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];

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 used NSURLConnection to communicate with Soap webservice and it worked fine.
Now I am using ASIFormDataRequest and I am not getting is it necessary to create soap message for that? and I am not aware what is SoapAction.
Here is the code I am using
NSURL *url = [NSURL URLWithString:#"http://SERVERNAME.com/WEBSERVICENAME"];
[self setFrmdataReq:[ASIFormDataRequest requestWithURL:url]];
[frmdataReq setRequestMethod:#"POST"];
[frmdataReq addRequestHeader:#"Content-Type" value:#"text/xml; charset=utf-8"];
[frmdataReq setPostValue:txtField.text forKey:#"city"];
[frmdataReq setDelegate:self];
[frmdataReq setDidFinishSelector:#selector(requestFinished:)];
[frmdataReq setDidFailSelector:#selector(requestFailed:)];
[frmdataReq startSynchronous];
UPDATE
Soap Message I used,
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSString *soapMessage = [NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"utf-8\"?>\
<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">\
<soap12:Body>\
<getCityTime xmlns=\"http://www.Nanonull.com/TimeService/\">\
<city>%#</city>\
</getCityTime>\
</soap12:Body>\
</soap12:Envelope>",txtField.text];
NSString *msgLength = [NSString stringWithFormat:#"%d",[soapMessage length]];
[request addValue:#"text/xml" forHTTPHeaderField:#"Content-Type"];
[request addValue:msgLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(conn)
{
responseData = [[NSMutableData data]retain];
NSLog(#"connection successful");
}
else
NSLog(#"connection fail.");
I didn't defined SOAPAction as I don't know anything about that.
When using ASIHTTPRequest, you need to create the SOAP request in basically the same way as you do with NSURLConnection.
The setPostValue call in ASIHTTPRequest is for create HTTP POST requests in the same format use for POST <form> tags in HTML.
For comparing ASIHTTPRequest / NSURLConnection, see things like:
ASIHTTPRequest vs NSURLConnection
and "What is ASIHTTPRequest?" on:

}
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.
Hi I want to pass my userName and Password to WCF Webservice from iPhone. I'm using ASIFormDataRequest.
Here is my code
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setRequestMethod:#"POST"];
[request setPostValue:txtUsername forKey:#"userName"];
[request setPostValue:txtPassword forKey:#"password"];
[request setDelegate:self];
[request addRequestHeader:#"Content-Type" value:#"application/json; charset=utf-8"];
[request startAsynchronous];
How do I pass JSON Data?
I could use this...
[request appendPostBody:jsonData]; // JSON as NSData
but how do I set JSON to NSData?
NSData *jsonData = #"{'userName':'john', 'password':'secret'}";
Please help me!
Supposing you want to encode the JSON in UTF-8 as stated in your header:
NSString *json = #"{'userName':'john', 'password':'secret'}";
NSData *jsonData = [json dataUsingEncoding:NSUTF8StringEncoding];
[request appendPostBody:jsonData];
NSURL *url = [NSURL URLWithString:#"someurl"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:year1 forKey:#"year"];
[request setPostValue:appy_level forKey:#"appy_level"];
[request setPostValue:reasons forKey:#"reasons"];
[request setPostValue:country forKey:#"country"];
[request setPostValue:city forKey:#"city"];
[request setPostValue:sex forKey:#"sex"];
[request setRequestMethod:#"POST"];
[request setValidatesSecureCertificate:NO];
[request setDelegate:self];
[request startAsynchronous];
NSLog(#"response -%#",[request responseString]);
[self dismissModalViewControllerAnimated:YES];
}
- (void)requestFinished:(ASIHTTPRequest *)request
{
NSString *response = [request responseString];
NSLog(#"%#",response);
}
any idea why this code return (null) i mean response is null? and this requestFinised: method isnt working even i write[requestsetDidFinishSelector:#selector(requestFinished)];
method too.I am confuesed right now.
The first NSLog won't work because you start your request as asynchronous.
You chould try putting NSLog(#"finished"); in -requestFinished: to check if page is loading or not. It can be an error in your server file (e.g. php fatal error).
Have you tried this:
NSString *response = [[NSString alloc] initWithData:[request data] encoding:NSUTF8StringEncoding];
NSLog(#"%#", response);
