How to upload image to server from gallery as JSON on iOS
ios, iphone, json
Solution
if you want to upload an image as a string you must convert your image data to Base64, then you can use your above method:-
For converting to a base64 string, refer to this Stack Overflow answer. You can then use your code for uploading.
Another Way
You can directly upload an image like so:
-(void)uploadImage
{
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *urlString = [ NSString stringWithFormat:@"http://yourUploadImageURl.php?intid=%@",1];
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:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n", 1]] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
}
Problem
How can I upload an image to a server from the gallery on iPhone as JSON? I tried the following: ``` [Loading startLoading:YES]; NSString *urlString = [NSString stringWithFormat:@"http://railsboxtech.com/singing/jsn_song/register_response.php?accesstoken=%@",Access_Token]; //username, password, name, email, country NSString *parameter = [NSString stringWithFormat:@"username=%@&password=%@&fname=%@&email=%@&lname=%@&btnImage4=%@",userField.text,passField.text,fnameField.text,emailField.text,lnameField.text,btnImage4]; NSConnection *conn = [[NSConnection alloc] initWithDelegate:self]; [conn sendRequest:urlString withParaMeter:parameter withMethod:@"POST" withTag:1]; [conn startAsynchronousRequest]; ```
