Attempting to send POST request to URL in iOS - ios

Question

I'm trying to post to a webserver in iOS but am receiving a 404 error. The person I'm working with is able to post from a different system with the address and data in a single string:
http://xxx.xxx.xxx.xxx/api/message?salu=mr&firstname=john&lastname=smith&email=smith#testemail.com&country=usa&zipcode=99999&checkbox=y&messagelist=message&q1=1&q2=2&q3=3&q4=4&q5=5
I'm trying to do the same with the following code in Xcode:
NSString *body = [NSString stringWithFormat:#"message?salu=mr&firstname=john&lastname=smith&email=matt#testmail.com&country=usa&zipcode=99999&checkbox=y&messagelist=message&q1=1&q2=2&q3=3&q4=4&q5=5"];
NSData *data = [body dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [data length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://xx.xxx.xxx.xxx/api"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:data];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *reply = [[NSString alloc] initWithBytes:[responseData bytes] length:[responseData length] encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", reply);
and the last few lines of 'reply' above from NSLog are:
<b> Description: </b>HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
<br><br>
<b> Requested URL: </b>/api<br><br>
</body>
However, I'm able to perform a 'GET' on the same address with the following code, where I receive the expected data:
NSMutableURLRequest *request2 = [[NSMutableURLRequest alloc] init];
[request2 setURL:[NSURL URLWithString:#"http://xx.xxx.xxx.xxx/api/message"]];
[request2 setHTTPMethod:#"GET"];
NSURLResponse *requestResponse;
NSData *requestHandler = [NSURLConnection sendSynchronousRequest:request2 returningResponse:&requestResponse error:nil];
NSString *requestReply = [[NSString alloc] initWithBytes:[requestHandler bytes] length:[requestHandler length] encoding:NSASCIIStringEncoding];
NSLog(#"requestReply: %#", requestReply);
So the web server is functioning and it appears the problem lies in the way I'm posting. Does anyone have an idea of what I'm doing wrong?

Answer 1

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://xx.xxx.xxx.xxx/api"]];
Don't you notice that you should call NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://xx.xxx.xxx.xxx/api/message"]];
/message is part of path, not request body.
and look forward to use some ready framework, such as AFNetworking is.

Answer 2

You've taken the last path component of the request's URL, message, and put that into the body of the request. So, replace:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://xx.xxx.xxx.xxx/api"]];
with
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://xx.xxx.xxx.xxx/api/message"]];
Also, replace:
NSString *body = [NSString stringWithFormat:#"message?salu=mr&firstname=john&lastname=smith&email=matt#testmail.com&country=usa&zipcode=99999&checkbox=y&messagelist=message&q1=1&q2=2&q3=3&q4=4&q5=5"];
with:
NSString *body = [NSString stringWithFormat:#"salu=mr&firstname=john&lastname=smith&email=matt#testmail.com&country=usa&zipcode=99999&checkbox=y&messagelist=message&q1=1&q2=2&q3=3&q4=4&q5=5"];
