将图片附加到AFNetworking 2.0请求的网址？ [英] Attach image at URL to AFNetworking 2.0 request?

问题描述

我想使用AFNetworking 2.0在iOS中执行此CURL请求：

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

使用此图片： http://s3.amazonaws.com/joinlook1/ffb9900d0ea123972d2fc5319ee2f9ec2abe691e.jpg

查看通过AFNetworking 2.0上传iOS图片

我试过：

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

但我一直收到错误： {errors：[http ：no such file]}

查看使用AFNetworking 2.0上传图片，我尝试使用扩展功能，但仍然得到相同的错误。

  [formData appendPartWithFileURL：[NSURL URLWithString：photo.urlString] name：@imagefileName：@photo.jpgmimeType：@image / jpegerror：& 
  

我也尝试过下载文件，然后使用其他帖子，但我一直得到相同的错误：

  __ 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 constructedBodyWithBlock：^（id< AFMultipartFormData> formData）{
 [formData appendPartWithFormData：imageData name： 图片]; 
} success：^（AFHTTPRequestOperation * operation，id responseObject）{
 NSLog（@Success：％@ *****％@，operation.responseString，responseObject）; 
}失败：^（AFHTTPRequestOperation * operation，NSError * error）{
 NSLog（@Error：％@ *****％@，operation.responseString，error）; 
}]; 
  

以下是完整的错误讯息：

如何在AFNetworking中将图片附加到表单请求？

c> c> c / cURL的名称 code> appendPartWithFileData 函数中的code>参数。如果我把它改为 name 它工作原理：

  [formData appendPartWithFileData： imageData name：@filefileName：@image.jpgmimeType：@image / jpeg]; 
  

但似乎我必须使用该方法。如果我尝试添加网址，它会继续失败：

  [formData appendPartWithFileURL：[NSURL URLWithString：@... ] name：@filefileName：@image.jpgmimeType：@image / jpeg错误：错误] 
  

，即使我使用文件URL

的真实文件名

I am trying to perform 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 iOS Image upload via 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 Uploading image with AFNetworking 2.0, I tried using the extended function, 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 uploading it with the exact code used in both of those other posts, but I kept getting 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 full 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 {

It is the same error if I download the image then attach it, or if I just attach it with the URL.

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

解决方案

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

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

But it seems I have to use that method. If I try just add the URL, it continues to fail:

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

even if I use the real filename from the file URL
