I get Nothing from the following code, which also does not produce an error.
(void)requestFinished:(ASIHTTPRequest *)request{
NSData *theData = [request responseData];
NSString *ret = [request responseString];
NSLog(#"ret--------------%#",ret);
}
When I use JSON, I get the result.

I am sending a JSON string to our server using the POST method. What should happen is that it should return a response showing "Array(JSON String) Array(JSON String)". The response contains two arrays: The first array is populated if I used the POST method, while the second array is populated if I use the GET method. I tried sending the JSON through GET method and indeed, the second array was populated. However, when I tried to send JSON through POST method, both arrays are returned empty.
Here is the code I used:
NSData *requestData = [NSJSONSerialization dataWithJSONObject:sqlArray options:NSJSONWritingPrettyPrinted error:&error];
NSURL *url = [NSURL URLWithString:#"http://myurl/xmlrpc/imwebsrvcjson.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:requestData];
NSData *result =[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *returnString = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
if (error == nil){
NSLog(#"The Result string: %#", returnString);
}
Can you tell me what is wrong with my code?
Here's what I do (please note that the JSON going to my server needs to be a dictionary with one value (another dictionary) for key = question..i.e. {:question => { dictionary } } ):
NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:#"StoreNickName"],
[[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:#"user_question"], nil];
NSArray *keys = [NSArray arrayWithObjects:#"nick_name", #"UDID", #"user_question", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:#"question"];
NSString *jsonRequest = [jsonDict JSONRepresentation];
NSLog(#"jsonRequest is %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"https://xxxxxxx.com/questions"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (connection) {
receivedData = [[NSMutableData data] retain];
}
The receivedData is then handled by:
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [jsonString JSONValue];
NSDictionary *question = [jsonDict objectForKey:#"question"];
This isn't 100% clear and will take some re-reading, but everything should be here to get you started. And from what I can tell, this is asynchronous. My UI is not locked up while these calls are made. Hope that helps.
i have this method -
NSArray *objects = [NSArray arrayWithObjects:appDelegate.UserID,itemName.text,#"1",#"1",itemDegem.text,itemDescription.text, nil];
NSArray *keys = [NSArray arrayWithObjects:#"userId",#"itemName",#"itemCategoryId",#"regionId",#"degemName",#"itemDescription", nil];
NSDictionary *registerDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSString *jsonRequest = [registerDict JSONRepresentation];
NSLog(#"jsonRequest is %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"http://www.somedomain.com/method"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (connection) {
self.responseData = [NSMutableData data];
}
but when i send strings in my objects that not in english im getting error from the server.
now, i know its a UTF8 problem, but i did set it to be UTF8. can someone please help me figure it out ?
I think the error is strlen([jsonRequest UTF8String]) is not equal to [jsonRequest length].
Use NSData *requestData = [jsonRequest dataUsingEncoding:NSUTF8StringEncoding]; to convert a NSString into NSData using UTF8 encoding.
I'm trying to send JSON post using NSURLConnection:
NSURL *url = [NSURL URLWithString:urlStr];
NSString *jsonPostBody = [NSString stringWithFormat:#"{\"user\":""\"%#\""",\"pass\":""\"%#\""",\"listades\":\"\"}",
[username stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
[password stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSLog(#"JSNON BODY:%#", jsonPostBody);
NSData *postData = [jsonPostBody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:10.0];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:postData];
[request setTimeoutInterval:2.0];
NSString* postDataLengthString = [[NSString alloc] initWithFormat:#"%d", [postData length]];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:postDataLengthString forHTTPHeaderField:#"Content-Length"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
App execution gets freeze when it reaches connection command, despite timeout.
I'm stucked in this issue and I can not find a solution.
Many thanks

It's freezing your app because you have passed YES into startImmediately. This will freeze the app until request is finished.
You need to use something like connectionWithRequest:delegate: - this will run the request in the background and tell you when it's done.
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
I'm trying to post to a rails backend from Objective-C and JSONKit and am having difficulty getting my results published. I keep getting back a null recordset from my server.
[dictionary setValue:(#"bar") forKey:#"foo"];
NSString *JSON = [dictionary JSONString];
NSData *theData = [JSON dataUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString: myUrl];
NSString *postLength = [NSString stringWithFormat:#"%d", [theData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
NSError *error = NULL;
NSURLResponse *response = nil;
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json-rpc" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:theData];
NSData *result = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response error:&error];
NSString *resultString = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
NSLog(resultString);
Is there something I'm missing? the JSON seems to be serializing correctly
{"foo":"bar"}
Any help would be greatly appreciated.
Thanks!
Just changed the setValue from json-rpc to json and it worked like a champ.
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
**[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];**
[request setCachePolicy:NSURLRequestReloadIgnoringCacheData];
[request setHTTPBody:theData];
