I'm sending a post request through webservices but I'm not getting the response I want.
Here's my code:
NSString *newurlString = [NSString stringWithFormat:#"{\"name\":\"asit\",\"email\":\"m.kulkarni#easternenterprise.com\",\"businessType\":\"1\",\"score\":30}"];
NSString * url = #"http://www.nieuwe-dag.nl/mobile_be/public/?action=saveScore";
//NSString *urlString =[NSString stringWithFormat:#"name=%#&email=%#&businessType=%d&score=%d",name, email, bussinesstype, score];
NSData *postData = [newurlString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSLog(#"urlString::%#",newurlString);
NSLog(#"postLength::%#",postLength);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:300];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLConnection *theConnection =[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (theConnection){
webData = [[NSMutableData data] retain];
}
else {
NSLog(#"theConnection is NULL");
}
You are setting the request type to json but you are not creating a json. The data you are creating is just nsstring. I think you need to create a json object. You can download JSON API from here:
https://github.com/stig/json-framework/
Use [SBJSONWriter dataWithObject:] to create a JSON object. Then pass it to your request.
FOr more info on JSON:
http://www.json.org/
You need proper postData
NSDictionary *dataDict = #{
#"name": #"asit",
#"email": #"m.kulkarni#easternenterprise.com",
#"businessType": #"1",
#"score": #(30)
};
NSData *postData = [NSJSONSerialization dataWithJSONObject:dataDict options:0 error:nil];

Hi I want to post XML data within JSON Object.
This is the way i post
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
NSString *postString = [NSString stringWithFormat:#"{\"UserId\":\"%#\",\"UserDataXML\":\"%#\"}",#"USRfa9210bad85165d5",#"<Root Bookmark=\"Page1\">\\u000d\\u000a <Name>MyName<\Name>\\u000d\\u000a <Address>MyAddress<\ Address></Root>"];
NSData *requestData = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:requestData];
In connectionDidFinishLoading _responseData is come,But responsedict is getting Null.
Where i am going wrong?
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(#"_responseData %#",_responseData);
NSString *responseString = [[NSString alloc] initWithData:_responseData encoding:NSUTF8StringEncoding];
NSError *error;
NSData *jsonData = [responseString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
NSLog(#"responseDict %#",responseDict);
}
First of all, you must escape your JSON before use.
And then,
(1) If the server is only responding with a form-data, a post data must be a pair of key and value.
NSString *postString = [NSString stringWithFormat:#"UserId=%#&UserDataXML=%#",
#"USRfa9210bad85165d5",
#"<Root Bookmark=\\\"Page1\\\">\\u000d\\u000a<Name>MyName</Name>\\u000d\\u000a<Address>MyAddress</Address></Root>"];
(2) If the server is only responding with JSON, Content-Type should be set to "application/json" and then,
NSString *postString = [NSString stringWithFormat:#"{\"UserId\":\"%#\", \"UserDataXML\":\"%#\"}",
#"USRfa9210bad85165d5",
#"<Root Bookmark=\\\"Page1\\\">\\u000d\\u000a<Name>MyName</Name>\\u000d\\u000a<Address>MyAddress</Address></Root>"];
BTW, have you checked the variable '_responseData'? I think it's also empty.
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
I have a problem. I need to convert base64 string to JSON string and pass it to server.
for example I have a base64 string /9j/4AAQSkZJRgABAQAAAQABAAD/4QBYRXhpZgAATU0AKgAAAAgAAgESAAMAAAABAAEAAIdpAAQAAAABAAAAJgAAAAAAA6ABAAMAAAABAAEAAKACAAQAAAABAAAACqADAAQAAAABAAAACgAAAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/Z
i need to convert it to JSON format. I do the following:
+(NSData *)prepareForUploading:(NSString *)base64Str
{
NSDictionary *dict=[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:base64str, nil] forKeys:[NSArray arrayWithObjects:#"picture", nil]];
NSData *preparedData=[NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:nil];
return preparedData;
};
here how I'm making NSURLRequest
-(NSString *)uploadPict:(NSString *)pict
{
NSLog(#"Server: upload: called");
NSData *prepPictData=[[self class] prepareForUploading:pict];
NSString *preparedBase64StrInJSON=[[NSString alloc] initWithData:prepPictData encoding:NSUTF8StringEncoding];
//here I'm adding access token to request
NSString *post = [NSString stringWithFormat:#"accessToken=%#&object=%#", self.key, preparedBase64StrInJSON];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#upload.aspx", serverAPIPath]]];
[request setHTTPMethod:#"POST"];
[request setValue:#"postLength" forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLResponse *response;
NSError *error;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
//....
}
But I get "Invalid length for a Base-64 char array" from server. What's wrong?
If I paste my token and JSON to http://hurl.it/ and make request using it - everything goes normally.
I think the problem is / symbols in base64 string and as a result / symbols in JSON.
Maybe it is something with [postData length]: if I erase \/ characters from JSON string:
9j4AAQSkZJRgABAQAAAQABAAD4QBYRXhpZgAATU0AKgAAAAgAAgESAAMAAAABAAEAAIdpAAQAAAABAAAAJgAAAAAAA6ABAAMAAAABAAEAAKACAAQAAAABAAAACqADAAQAAAABAAAACgAAAAD2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQHZ request will perform normally but this base64 encoded string is not the same.
Please, help me to solve this problem
jString is your base64 string, first use following line
[self encodeString:jString];
and then call use following.
NSString *URL = [NSString stringWithFormat:#"forms.asmx/CreateUpdate?"];
URL=[NSString stringWithFormat:#"%#%#", USERS_API_ROOT_URL, URL];
NSString *post = [NSString stringWithFormat:#"apiKey=A0B1I2L3A4L5-A1D3-4F30-5AB2-C8DEE266&strPost=%#",jString];
unsigned long long postLength = [post length];
NSString *contentLength = [NSString stringWithFormat:#"%llu",postLength];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:URL]];
[request setHTTPMethod:#"POST"];
[request setValue:contentLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData ];
(void)[[NSURLConnection alloc] initWithRequest:request delegate:self];
-(NSString *)encodeString:(NSString *)string
{
NSString *newString = (__bridge_transfer NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)string, NULL,CFSTR(":/?#[]#!$ &'()*+,;=\"<>%{}|\\^~`"), CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
return newString;
}
Hope it will work.
GET Method, it works fine.
url: http://myurl.com/test.html?query=id=123&name=kkk
I do not have concepts of POST method. Please help me.
How can I chagne GET method to POST method?
url: http://testurl.com/test.html
[urlRequest setHTTPMethod:#"POST"];
try this
NSString *post = [NSString stringWithFormat:#"username=%#&password=%#",username.text,password.text];
NSLog(#"%#",post);
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:#" server link here"]]];
[request setHTTPMethod:#"POST"];
NSString *json = #"{}";
NSMutableData *body = [[NSMutableData alloc] init];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:postData];
//get response
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[NSError alloc] init];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300)
{
NSLog(#"Response: %#", result);
}
// create mutable request
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
// set GET or POST method
[request setHTTPMethod:#"POST"];
// adding keys with values
NSString *post = #"query=id=123&name=kkk";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
[request addValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
I am new to iPhone programming, and this is the first time parsing XML file. I have added the url and also hardcoded the XML file into the string, however I am not getting the correct response from the server.
Here is my code:
NSString *post = #"<?xml version=\"1.0\"encoding=\"UTF-8\"?<request><call>GetNewChapters</call><udid>1000000000000000000000000000000000000000</udid><book_id>1</book_id><updatetoken>B20100125054802</updatetoken></request>";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSURL *url=[NSURL URLWithString:#"https://www.paisible.com/babelle_api"];
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];
NSString *myStr = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
NSLog(#"String Value :%#",myStr);
NSLog(#"theRequest: %#", request);
NSURL *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(theConnection)
{
webData = [[NSMutableData data] retain];
}
else
{
NSLog(#"theConnection is NULL");
}
Where as webdata is NSMutable data. Please let me know what errors I have made in my parsing code.
Try to replace
NSURL *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
with the following:
NSURLResponse *resp;
NSError *error;
NSMutableData *webData = [NSURLConnection sendSynchronousRequest:request returningResponse:&resp error:&error];
Than, check what "webData" contains.
