將URL附加到AFNetworking 2.0請求的URL？

我想執行使用的是iOS這種捲曲要求AFNetworking 2.0：使用這個圖像將URL附加到AFNetworking 2.0請求的URL？

curl -F "[email protected]" "https://image.groupme.com/pictures?access_token=token123"

：http://s3.amazonaws.com/joinlook1/ffb9900d0ea123972d2fc5319ee2f9ec2abe691e.jpg

我想：

[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); 
}];

但我不斷收到錯誤：{"errors":["http: no such file"]}

看着Uploading image with AFNetworking 2.0，我試過使用擴展函數，但不斷得到相同的錯誤。

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

我也是第一次嘗試下載該文件，然後在這兩個其他職位所用的確切代碼上傳，但我一直得到了同樣的錯誤：

__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); 
}];

下面是完整的錯誤消息：

這是相同的錯誤，如果我下載的圖像，然後將其固定，或者如果我只是用URL連接它。

如何將圖像附加到AFNetworking中的表單請求？

使用'[FORMDATA appendPartWithFileData：名稱：文件名：mime類型：]'，不'[formData appendPartWithFormData：name：]' – dirkgroten

看起來像file cURL的一部分與appendPartWithFileData函數中的name參數相關。如果我將其更改爲name它的工作原理：

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

但似乎我必須使用該方法。如果我嘗試剛纔添加的網址，仍然失敗：

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

即使我用的是真實的文件名從文件URL
