【问题描述】：

我想使用 AFNetworking 上传多张图片。 像这样Please Check This Image

我附上了邮递员的例子。

我的代码：

NSString *key = [[mediaInfo allKeys] objectAtIndex:0];
NSDictionary *dict = [[mediaInfo objectForKey:key] objectAtIndex:0];
UIImage *image = [dict objectForKey:IQMediaImage];

NSMutableDictionary    *dictParam = [[NSMutableDictionary alloc] init];
[dictParam setValue:imageData forKey:@"Files"];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager POST:@BaseURL(@"/MediaUpload") parameters:dictParam progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) 

     failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error)   ];

AFNetworking 3.0

【参考方案1】：

从AFURLSessionManager查看这个方法：

- (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request
                                     fromFile:(NSURL *)fileURL
                                     progress:(void (^)(NSProgress *uploadProgress)) uploadProgressBlock
                            completionHandler:(void (^)(NSURLResponse *response, id responseObject, NSError *error))completionHandler

完整代码实现：

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *sessionManager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

[[sessionManager uploadTaskWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@BaseURL(@"/MediaUpload")]]
                              fromFile:[NSURL fileURLWithPath:@"/path/to/uploading_file"]
                              progress:^(NSProgress * _Nonnull uploadProgress)  
                     completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) 
] resume];

【参考方案2】：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"multipart/form­data" forHTTPHeaderField:@"Content-Type"];

[manager POST:[NSString stringWithFormat:@"%@/api/1.0/customer/sign-up", DEFAULT_URL] parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) 

if (userHaveImage == YES) 
    [formData appendPartWithFileData:image name:@"img_profile" fileName:@"profileImage.jpg" mimeType:@"image/jpg"];
    [formData appendPartWithFormData:image name:@"img_profile"];

然后将图像转换为 UTF8 字符串并以该格式发送。

【讨论】：

你的回答是对的。但我问我们可以直接传递图像吗？无需转换数据。或者没有传递图像 URL。
