I want to make http form post using NSURLConnection in IOS.I have two form field and one file upload option in html form.When I am doing same thing using NSURLConnection I am not getting response.
NSString *urlString = @"http://url/test.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data"];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"file\"; filename=\"myphoto.png\"rn"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:filedata];
[body appendData:[[NSString stringWithFormat:@"&s=YL4e6ouKirNDgCk0xV2HKixt&hw=141246514ytdjadh"] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"RETURNED:%@",returnString);
But when I am using http://allseeing-i.com/ASIHTTPRequest/How-to-use and write the following code it's working and I am getting response.
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://url/test.php"]];
[request setPostValue:@"YL4e6ouKirNDgCk0xV2HKixt&hw" forKey:@"s"];
[request setPostValue:@"141246514ytdjadh" forKey:@"hw"];
[request setData:filedata withFileName:@"myphoto.png" andContentType:@"image/jpeg" forKey:@"file"];
[request startSynchronous];
NSError *error = [request error];
if (!error)
{
NSString *response = [request responseString];
NSLog(@"response:%@",response);
}
Can anyone tell me in NSURLConnection part where I am doing wrong.
Thanks in advance
You are not copying the example of that link. In that tutorial, the HTTPBody parameter is supposed to by an instance of NSData, not NSString.
ReplyDelete[request setHTTPMethod:@"POST"];
NSString *myString = [NSString stringWithFormat:@"value1=test3&value2=test"];
[request setHTTPBody:[myString dataUsingEncoding:NSUTF8StringEncoding]];
Try this ....
ReplyDeleteNSURL *url = [NSURL URLWithString:@"URL"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
NSString *myRequestString =@"Request string";
NSLog(@"%@",myRequestString);
NSData *myRequestData = [ NSData dataWithBytes: [ myRequestString UTF8String ] length: [ myRequestString length ] ];
[ request setHTTPBody: myRequestData ];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *content = [NSString stringWithUTF8String:[responseData bytes]];
I tried this code for uploading the image and its working. Added boundry.
ReplyDeleteNSString *urlString = @"URL";
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"Test.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
