I am developing an application in which i want to post
xml data as request but i am not able to post it correctly ,i think.
My request xml data is
<loginRequest><username>101</username></loginRequest>
and my request is as follows :
`NSString *post=#"<loginRequest><username>101</username></loginRequest>";
NSURL *url = [NSURL URLWithString:#"my url"];
__block ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setRequestMethod:#"POST"];
NSMutableData *mutData=[[NSMutableData alloc]init];
[request addRequestHeader:#"Content-Type" value:#"text/xml"];
[request setPostValue:#"test" forKey:#"body"];
[request setCompletionBlock:^{
NSData *data=[request responseData];
NSString *response=[request responseString];
}];
[request setFailedBlock:^{
NSLog(#"Failed");
}];
[request startAsynchronous];
`
Kindly help me with this..
You can check with your server api whether it supports different response type..
Accordingly you can set "Accept" parameter of HTTP request header.
[request addRequestHeader:#"Accept" value:#"application/xml"];

I have a website that i want to log into from my iphone in a iphone app i am making, i followed the documentation on ASIHttpRequests website but all i get from the response string is the html code for the login page , but i get a OK http code, Why is this happening?
Here is my code :
-(IBAction)fetchData:(id)sender
{
NSURL *url = [NSURL URLWithString:#"http://www.rssit.site90.com/login.php"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request shouldPresentCredentialsBeforeChallenge];
[request setRequestMethod:#"POST"];
[request setPostValue:#"" forKey:#"username"];
[request setPostValue:#"" forKey:#"password"];
[request setDelegate:self];
[request startAsynchronous];
//Add finish or failed selector
[request setDidFinishSelector:#selector(requestLoginFinished:)];
[request setDidFailSelector:#selector(requestLoginFailed:)];
}
- (void)requestLoginFinished:(ASIHTTPRequest *)request
{
NSString *yourResponse = [request responseString];
NSLog(#"%#", yourResponse);
}
The form on that page is doing a get, not a post. Your server is probably not expecting POST data, and is looking at query string params instead. Change to
[NSURL URLWithString:#"http://www.rssit.site90.com/login.php?username=YOURUSERNAME&password=YOURPASSWORD"];
and set the requestMethod to GET.
I have changed over to NSURLConnection and NSURLRequest delegates for my db connections etc.
I was using the ASIHTTPRequest libraries to do all this stuff but finally decided to move on due to the lack of support for that 3rd party library.
what I am woundering is how do I send post requests to my db like you do with the ASIFormDataRequest as shown below
//This sets up all other request
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request setValidatesSecureCertificate:NO];
[request setPostValue:#"ClientDataSet.xml" forKey:#"filename"];
[request startSynchronous];
i.e. how to do send the setPostValues with the NSURLRequest class?
any help would be greatly appreciated
Using NSURLRequest is slightly more difficult than utilizing ASIHTTPRequest. You have to build your own post body.
NSData *postBodyData = [NSData dataWithBytes: [postBodyString UTF8String] length:[postBodyString length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:yourURL];
[request setHTTPMethod: #"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setHTTPBody:postBodyData];
how can i use the get method to post data on an api link with 6 values and a json format?
im really fuzzled. im doing this for days . is it best to have 6 textfields that will be used to write the value and a button to indicate post data?
check out my code and please help.
-(IBAction)postDataPressed
{
NSString *urlString = #"http://192.168.18.8/apisample2/friendb.php?fm=jsn";
NSURL *url = [NSURL URLWithString:urlString];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:user.text forKey:#"un"];
[request setPostValue:pass.text forKey:#"pd"];
[request setPostValue:gender.text forKey:#"gd"];
[request setPostValue:age.text forKey:#"ag"];
[request setPostValue:status.text forKey:#"st"];
[request setPostValue:lookfor.text forKey:#"lf"];
[request setRequestMethod:#"GET"];
[request setCompletionBlock:^{
NSString *responseString = [request responseString];
NSLog(#"Response: %#", responseString);
}];
[request setFailedBlock:^{
NSError *error = [request error];
NSLog(#"Error: %#", error.localizedDescription);
}];
[request setDidFinishSelector:#selector(requestFinished:)];
[request setDidFailSelector:#selector(requestFailed:)];
[request startAsynchronous];
}
i hope someone will help.
NSString *request_url = [NSString stringWithFormat: #"http://192.168.18.8/apisample2/friendb.php?fm=jsn&un=%#&pd=%#&gd=%#&ag=%#&st=%#&lf=%#",
user.text, pass.text, gender.text, age.text,status.text,lookfor.text];
NSURL *url = [NSURL URLWithString:request_url];
ASIHttpRequest *request = [ASIHttpRequest requestWithURL:url];
request.delegate = self;
....
HTTP Get method only accept data in url, called query string, so you have to build query string yourself.
people,
I'm using JSON touch inmy iphone app.
Now I have to send a string and then an array to server, how can I do this?
I get data from json requests succefully, but I have to send some data.
Here is the code I've got so far:
-(void)subimtSelection:(int)aNumber
{
NSString *choiceData=[NSString stringWithFormat:#"%d", aNumber];
NSError *theError=nil;
[[CJSONSerializer serializer] serializeString:choiceData error:&theError];
NSDictionary *jsDic=[NSDictionary dictionaryWithObject:choiceData
forKey:#"selection"];
//WHAT SHOULD I DO NEXT?
}
You can use ASIHTTRequest to POST string/json data to server:
ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:#"http://server.url"];
[request addRequestHeader:#"Accept" value:#"application/json"];
[request addRequestHeader:#"Content-Type" value:#"application/json"];
[request setRequestMethod:#"POST"];
[request appendPostData:[yourJSONString dataUsingEncoding:NSUTF8StringEncoding]];
[request startSynchronous];
If you want to post a string value then try:
[request appendPostData:#"key=value"];
ASIHTTPRequest can be used in asynchronious mode as well.
P.S. I did not tested the code, but it should work.
To post form data you can use ASIFormDataRequest, documentation is here
I'm using ASIHTTPRequest and json-framework to post JSON to a rails app,
The problem is that when the JSON arrives on the server it is wrapped in double quotes,
Here is the code i am using to encode and send the JSON:
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#/shared_lists.json",kAPIRoot]]];
NSString *dataString = [NSString stringWithFormat:#"shared_items=%#&shared_list=%#&facebook_id=%#",[sharedItems JSONRepresentation],[sharedList JSONRepresentation],facebookID];
NSLog(#"%#",[NSString stringWithUTF8String:[[dataString dataUsingEncoding:NSUTF8StringEncoding] bytes]]);
[request appendPostData:[dataString dataUsingEncoding:NSUTF8StringEncoding]];
[request setRequestMethod:#"POST"];
[request setDelegate:self];
[request setDidFinishSelector:#selector(requestDone:)];
[request setDidFailSelector:#selector(requestWentWrong:)];
[queue addOperation:request];
Which logs correctly as:
shared_items=[{"entity_id":"531","position":"1"},{"entity_id":"733","position":"2"},{"entity_id":"723","position":"3"},{"entity_id":"2530","position":"4"}]&shared_list={"list_id":1197}&facebook_id=-1540981104
Although when it arrives on the server it outputs as:
shared_items="[{"entity_id":"531","position":"1"},{"entity_id":"733","position":"2"},{"entity_id":"723","position":"3"},{"entity_id":"2530","position":"4"}]",shared_list="{"list_id":1197}",facebook_id="-1540981104"
How do i stop the arrays being wrapped up as a single string?
Try this way:
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#/shared_lists.json",kAPIRoot]]];
NSString *dataString = [NSString stringWithFormat:#"shared_items=%#&shared_list=%#&facebook_id=%#",[sharedItems JSONRepresentation],[sharedList JSONRepresentation],facebookID];
NSMutableData *requestBody = [[NSMutableData alloc] initWithData:[dataString dataUsingEncoding:NSUTF8StringEncoding]];
[request setRequestMethod:#"POST"];
[request setPostBody:requestBody];
[request addRequestHeader:#"Content-Type" value:#"application/json; encoding=utf-8"];
[request setUseSessionPersistence:NO];
[request setUseCookiePersistence:NO];
[request setCacheStoragePolicy:ASICacheForSessionDurationCacheStoragePolicy];
I solved the problem by manually creating the JSON String like so:
NSString *dataString = [NSString stringWithFormat:#"{\"shared_items\":%#,\"shared_list\":%#,\"facebook_id\":%#}",[sharedItems JSONRepresentation],[sharedList JSONRepresentation],facebookID];
