xml parsing with Post method+iphone - iphone

I am having problem with xmlparsing with post method.
API URL : http://XXX.XXX.X.XX/api/user.php
Function Name : getUserList
Sample XML :
<root>
<data>
<id>0</id>
<search></search>
</data>
</root>
Now i am using :-
// setting up the URL to post to
NSString *urlString = #"http://XXX.XXX.X.XX/api/user.php";
// setting up the request object now
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
But how should i make the post HTMLbody part in this..
Means where and how should i put functional name and sample xml in the code
My Edited Question is :-
NSString *urlString = #" http://192.168.6.79/silverAPI/api/user.php/getUserList";
// setting up the request object now
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString * str = #"<root><data><id>0</id><search>a</search></data></root>";
NSString * message= [NSString stringWithFormat:#"/getUserList mydata=%#", str];
[request setHTTPBody:[message dataUsingEncoding:NSUTF8StringEncoding]];
[request addValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"Responce==>%#",returnString);
But i getting black in responce.Pleaseee help me out..
is my
NSString *urlString = #" http://192.168.6.79/silverAPI/api/user.php/getUserList";
And
NSString * str =
#"0a";
NSString * message= [NSString stringWithFormat:#"/getUserList
mydata=%#", str];
[request setHTTPBody:[message
dataUsingEncoding:NSUTF8StringEncoding]];
[request addValue:#"application/xml; charset=utf-8"
forHTTPHeaderField:#"Content-Type"];
This part of code is correct??

You can set html body using method - (void)setHTTPBody:(NSData *)data. For example:
[request setHTTPBody:[message dataUsingEncoding:NSUTF8StringEncoding]];
where message is,in your case, xml.
Also you need to add this code to help server to determine type of sent data:
[request addValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
If you want to set some additional flags to your request you can use method - (void)setValue:(NSString *)value forHTTPHeaderField:(NSString *)field.

What you have done is perfect, please check on server side whether response from there is coming properly by sending the same request or not.

Add new place to Google Places

I am new to IOS. I have to add new places to Google Places. I have referred this link https://developers.google.com/places/documentation/actions to add a place on button click, but I'm confused about passing parameters for this.
My coding lines are like this to fetch:
NSString *lat =#"-33.8669710";
NSString *longt =#"151.1957362";
gKey = #"my api key";
NSString *placeString = [NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/add/json?sensor=false&key=%#HTTP/1.1Host:maps.googleapis.com {\"location\":{\"lat\":%#,\"lng\":%#},\"accuracy\": 50,\"name\":\"Gimmy Pet Store!\",\"types\":[\"pet_store\"],\"language\":\"en-AU\"}",gKey,lat,longt];
placeString = [placeString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"Main Place Url: %#",placeString);
NSURL *placeURL = [NSURL URLWithString:placeString];
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:placeURL];
[request setHTTPMethod:#"POST"];
NSURLConnection *placesConn =[[NSURLConnection alloc] initWithRequest:request delegate:self];
I have made following changes to my code & finally it is executed successfully...
//for setting Parameters to post the url.just change tag values to below line...
NSString *str1 = [NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><PlaceAddRequest><location><lat>your latitude</lat><lng>your longitude</lng></location><accuracy>50</accuracy><name>place name</name><type>supported type</type><language>en-US</language></PlaceAddRequest>"];
NSLog(#"str1=====%#",str1);
NSString *str2 = [str1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSData *requestdata = [NSData dataWithBytes:[str2 UTF8String] length:[str2 length]];
NSString *postLength = [NSString stringWithFormat:#"%d", [requestdata length]];
//requesting main url to add new place to google places
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/add/xml?sensor=false&key=your api key"]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[NSData dataWithBytes:[str1 UTF8String] length:[str1 length]]];
//NSURLConnection *placesConn =[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSData *returndata = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnstr = [[[NSString alloc] initWithData:returndata encoding:NSUTF8StringEncoding] autorelease];
NSLog(#"returnstr: %#",returnstr);
& then i have decoded return response which i get i status as OK......:)
Any one can use above code...if any help require you can surely ask....:)

JSON parsing, How to get response from server

I have the following details, for get the data from server. What is the use of methodIdentifier and web service name ?
{"zip":"12345","methodIdentifier":"s_dealer"}
url:- http://xxxxxxxxxxxxxxx.com/api.php
method: post
web service name: s_dealer
response : {"success":"0","dealer":[info...]}
I don't know how to send zip number "12345" with the url. Please direct me on right direction. I use the following.
-(void)IconClicked:(NSString *)zipNumber
{
NSString *post = [NSString stringWithFormat:#"&zipNumber=%#",zipNumber];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://xxxxxxxxxxxxxxxxxxx.com/api.php"]]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(conn)
{
NSLog(#"Connection Successful");
}
else
{
NSLog(#"Connection could not be made");
}
receivedData = [[NSMutableData alloc]init];
}
when i print the response in console :\"Unexpected end of string\"
Without knowing more about the API, I can't be certain about your requirements, but it seems that the server is expecting the request to contain JSON. The way you currently are creating the body for the request is using standard POST variables.
Have you tried changing:
NSString *post = [NSString stringWithFormat:#"&zipNumber=%#",zipNumber];
to:
NSString *post = [NSString stringWithFormat:#"{\"zip\":\"%#\",\"methodIdentifier\":\"s_dealer\"}",zipNumber];
Regarding your other questions, I'm guessing that there is a single URL for the API. The methodidentifier is used by the server in order to determine which server method(s) to run.
You get this error because you do not get a json as a response, but an error from Apache (or whatever), that has different structure, and json cannot parse it. Try my method to initiate the connection, in order to gain a successful one.
Declare a NSURLConnection property and synthesize it. Now:
NSString *post = [NSString stringWithFormat:#"zipNumber=%#",zipNumber];
NSString *toServer = [NSString stringWithString:#"your server with the last slash character"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#api.php?", toServer]];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *urlRequest = [[[NSMutableURLRequest alloc] init] autorelease];
[urlRequest setURL:url];
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setValue:postLength forHTTPHeaderField:#"Content-Length"];
[urlRequest setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[urlRequest setValue:#"utf-8" forHTTPHeaderField:#"charset"];
[urlRequest setHTTPBody:postData];
[urlRequest setTimeoutInterval:30];
NSURLConnection *tmpConn = [[[NSURLConnection alloc] initWithRequest:urlRequest delegate:self] autorelease];
self.yourConnectionProperty = tmpConn;
Now you work with self.yourConnectionProperty in connection delegates. Cheers!
hey bro check my answer for same problem may help you... You have to use the NSURLConnection Delegates to get the data
Could not make Json Request body from Iphone

Fetch POST value in coldfusion from objective C

I am trying to post a string to a URL in iphone which will be retrieved by the server. The server side scripting is done in coldfusion. I am trying to fetch the data in coldfusion and pass on the value back to iphone. I am not familiar much with coldfusion and wanted some help in this. Below is the coding in iphone :
/** Iphone code **/
NSString *post =[[NSString alloc] initWithString:#"Hello World"];
NSURL *url=[NSURL URLWithString:#"http://www.abc.com/test.cfm"];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
/*Coldfusion code */
<html>
<head><title>Test</title></head>
<body>
<cfoutput>#form.post#</cfoutput>
</body>
</html>
Am I doing it correctly ?
You may need to specify name of form variable in data. Try below for post variable. I haven't tested it should work.
NSString *post =[[NSString alloc] initWithString:#"post=Hello%20World"];

Why this POST don't work?

this is my snippet:
NSString *post = #"from=A&name=B&email=ciccio#aaasd.com&messaggio=MESSAGE&codHidden=-1";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://www.mysite.com/page.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSData *urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSLog(#"Succeeded! Received %d bytes of data",[urlData length]);
NSString *outputdata = [[NSString alloc] initWithData:urlData encoding:NSASCIIStringEncoding];
NSLog(#"%#", outputdata);
It call a php page that send me an email...
Is there any errors in this code?
Does not seem to work...
thanks
Is it a Synchronous/Asynchronous problem? If so, use the delegate-pattern and access the data asynchronously. Could you post any errors you see (or the server's response string)?
EDIT: Since you're not doing anything useful with the error returned, change your class to do the request asynchronously. A great answer to this was previously posted here. Once you implement didFailWithError you'll have a better picture.
Try to change NSASCIIStringEncoding to NSUTF8StringEncoding

iPhone sending POST with NSURLConnection

I'm having some problems with sending POST data to a PHP script with NSURLConnection. This is my code:
const char *bytes = [[NSString stringWithFormat:#"<?xml version=\"1.0\"?>\n<mydata>%#</mydata>", data] UTF8String];
NSURL *url = [NSURL URLWithString:#"http://myurl.com/script.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[NSData dataWithBytes:bytes length:strlen(bytes)]];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSLog(#"responseData: %#", responseData);
And my script.php is as simple as this:
<?php
echo $_POST['mydata'];
?>
This have worked for me in the past, but for some reason the output I get from NSLog(#"responseData: %#", responseData); now is just "<>" instead of "theData".
Probably some lame mistake somewhere but I can't seem to find it? Any ideas?
Your data is wrong. If you expect the data to be found in the $_POST array of PHP, it should look like this:
const char *bytes = "mydata=Hello%20World";
If you want to send XML Data, you need to set a different HTTP Content Type. E.g. you might set
application/xml; charset=utf-8
If you set no HTTP Content Type, the default type
application/x-www-form-urlencoded
will be used. And this type expects the POST data to have the same format as it would have in a GET request.
However, if you set a different HTTP Content Type, like application/xml, then this data is not added to the $_POST array in PHP. You will have to read the raw from the input stream.
Try this:
NSString * str = [NSString stringWithFormat:#"<?xml version=\"1.0\"?>\n<mydata>%#</mydata>", data];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:[str dataUsingEncoding:NSUTF8StringEncoding]];
and on the server try the following PHP:
$handle = fopen("php://input", "rb");
$http_raw_post_data = '';
while (!feof($handle)) {
$http_raw_post_data .= fread($handle, 8192);
}
fclose($handle);
Please note that this only works if the HTTP header of your POST is not application/x-www-form-urlencoded. If it is application/x-www-form-urlencoded then PHP itself reads all the post data, decodes it (splitting it into key/value pairs), and finally adds it to the $_POST array.
Ah yeah... cheers. But the responseData output is like "<48656c6c 6f326f72 6c64>", don't you print NSData with %#? – per_pilot Jan 15 '10 at 13:57
that is because you are showing the "bytes" values you should pass it to NSString to see the real message
NSString *string = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];
NSLog(#"responseData: %#", string);
NSString *post =[NSString stringWithFormat:#"usertype(%#),loginname(%#),password(%#)",txtuser.text,txtusername.text,txtpassword.text];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://www.dacinci.com/app/tes2/login_verify.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
POST data and XML data are not the same. You can send XML data just as you did, but the PHP code must parse the XML from the request body. PHP's xml_parse (http://php.net/manual/en/function.xml-parse.php) can help you do this.
Alternatively, if you would prefer sending POST data, set the request body like this:
const char *bytes = [[NSString stringWithFormat:#"mydata=%#", data] UTF8String];
If you use NSURLSession then in iOS9 set
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request addValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"application/json" forHTTPHeaderField:#"Accept"];
request.HTTPMethod = #"POST";
In PHP set
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to SQL.";
//select a database to work with
$selected = mysql_select_db($db,$dbhandle)
or die("Could not select anons db");
echo "Connected to DB sucess.";
mysql_query("SET NAMES 'utf8'");
mysql_query("SET CHARACTER SET 'utf8'");
mysql_query("SET SESSION collation_connection = 'utf8_general_ci'");
In the db (MySql5) set utf-8_generic.
