通过AFNetworking 2.0上传iOS图片 [英] iOS Image upload via AFNetworking 2.0

问题描述

我一直在寻找新的AFNetworking 2.0上传图像的示例。
但是我碰壁了，无法弄清楚代码出了什么问题。
这就是我使用的代码

I've been looking examples for the new AFNetworking 2.0 to upload images. But I'm hitting wall and couldn't figure out what's wrong with the code. So this is the code I used

NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];


AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://myserverurl.com"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromData:imageData progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"Success: %@ %@", response, responseObject);
    }
}];
[uploadTask resume];

TIA

推荐答案

我最终使用了多部分请求

I ended up using the multi-part request

UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFormData:imageData name:@"image"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
