AFNetworking 上传文件

@第一种:我的

#pragma mark - AFNetworking上传文件
- (void)didClickUploadButtonAction{

    NSString *fileName = @"hmt";
    //  确定需要上传的文件(假设选择本地的文件)
    NSURL *filePath = [[NSBundle mainBundle] URLForResource:fileName withExtension:@"png"];
    NSDictionary *parameters = @{@"name":@"额外的请求参数"};
    AFHTTPRequestOperationManager *requestManager = [AFHTTPRequestOperationManager manager];
    [requestManager POST:@"http://192.168.10.18:8080/AFNetworkingServer/upload" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        
        /**
         *  appendPartWithFileURL   //  指定上传的文件
         *  name                    //  指定在服务器中获取对应文件或文本时的key
         *  fileName                //  指定上传文件的原始文件名
         *  mimeType                //  指定商家文件的MIME类型
         */
        [formData appendPartWithFileURL:filePath name:@"file" fileName:[NSString stringWithFormat:@"%@.png",fileName] mimeType:@"image/png" error:nil];
        
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        
        [[[UIAlertView alloc] initWithTitle:@"上传结果" message:[[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]  delegate:self cancelButtonTitle:@"" otherButtonTitles:nil] show];
        
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        
        NSLog(@"获取服务器响应出错");
        
    }];
    
}

@第二种:(朋友的)

    NSData *imageData = UIImagePNGRepresentation(image);
    
    //转码成UTF-8  否则可能会出现错误
    
    
    NSString *URLTmp = [NSString stringWithFormat:@"%@%@",CGBaseURL,path];
    
    NSString *URLTmps = [URLTmp stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    
    URLTmp = URLTmps;
    
    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:URLTmp parameters:body constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        
        [formData appendPartWithFileData:imageData name:@"headerImg" fileName:@"123.png" mimeType:@"image/png"];
        
    } error:nil];
    
    
    
    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
    
    NSProgress *progress = nil;
    

    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

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