Attach image to url in AFNetworking 2.0 request?

Question

I am trying to execute this CURL request in iOS using AFNetworking 2.0:

curl -F "file=@picture.jpg" "https://image.groupme.com/pictures?access_token=token123"

using this image: http://s3.amazonaws.com/joinlook1/ffb9900d0ea123972d2fc5319ee2f9ec2abe691e.jpg

Looking at Downloading an iOS Image Through AFNetworking 2.0

I tried:

 [self POST:[NSString stringWithFormat:@"pictures?access_token=%@", access_token] parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { NSError *error; [formData appendPartWithFileURL:[NSURL URLWithString:@"http://s3.amazonaws.com/joinlook1/ffb9900d0ea123972d2fc5319ee2f9ec2abe691e.jpg"] name:@"image" error:&error]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@ ***** %@", operation.responseString, error); }]; 

but I kept getting the error: {"errors":["http: no such file"]}

Looking at Downloading an image with AFNetworking 2.0 , I tried to use the advanced feature, but kept getting the same error.

 [formData appendPartWithFileURL:[NSURL URLWithString:photo.urlString] name:@"image" fileName:@"photo.jpg" mimeType:@"image/jpeg" error:&error]; 

I also tried downloading the file first and then downloading it using the exact code used in both of these posts, but I still got the same error:

 __block NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://s3.amazonaws.com/joinlook1/ffb9900d0ea123972d2fc5319ee2f9ec2abe691e.jpg"]]; NSDictionary *parameters = @{@"image":@"YES"}; [self POST:[NSString stringWithFormat:@"pictures?access_token=%@", access_token] parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFormData:imageData name:@"image"]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@ ***** %@", operation.responseString, error); }]; 

Here is the complete error message:

 ***** Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x14fa92dc0> { URL: https://image.groupme.com/pictures?access_token=XXXX } { status code: 400, headers { "Access-Control-Allow-Credentials" = false; "Access-Control-Allow-Headers" = "Accept, Content-Type, X-Requested-With, X-Access-Token, User-Agent, Pragma, Referrer, Cache-Control, Origin"; "Access-Control-Allow-Methods" = "POST, GET, PUT, DELETE, OPTIONS"; "Access-Control-Allow-Origin" = "*"; "Access-Control-Max-Age" = 86400; "Cache-Control" = "must-revalidate, private, max-age=0"; Connection = "keep-alive"; "Content-Length" = 34; "Content-Type" = "application/json;charset=utf-8"; Date = "Tue, 19 Apr 2016 09:50:42 GMT"; Server = "nginx/1.8.1"; "X-Gm-Service" = "image-service"; } }, NSErrorFailingURLKey=https://image.groupme.com/pictures?access_token=XXXXX, com.alamofire.serialization.response.error.data=<7b226572 726f7273 223a5b22 68747470 3a206e6f 20737563 68206669 6c65225d 7d0a>, NSLocalizedDescription=Request failed: bad request (400)} 

This is the same error if I upload an image and then attach it or just add it with a url.

How can I attach an image to a form request in AFNetworking?

Answer 1

Looks like the file cURL part correlated with the name parameter in the appendPartWithFileData function. If I change it to name , it will work:

 [formData appendPartWithFileData:imageData name:@"file" fileName:@"image.jpg" mimeType:@"image/jpeg"]; 

But it seems to me that I should use this method. If I try to just add the URL, it will continue to work:

 [formData appendPartWithFileURL:[NSURL URLWithString:@"..."] name:@"file" fileName:@"image.jpg" mimeType:@"image/jpeg" error:&error] 

even if I use the real file name from the file url
