【问题描述】：

我正在尝试使用 AFNetworking 3.0 将图像上传到我的服务器。我的服务器返回“请选择要上传的文件。”。这是我如何在我的 php 文件 $filename = $_FILES["file"]["name"]; 中捕获上传的文件。

-(void)uplodeImages :(NSString *)image 
    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://local/upload.php" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 
        [formData appendPartWithFileURL:[NSURL fileURLWithPath:image] name:@"file" fileName:@"imagename.jpg" mimeType:@"image/jpeg" error:nil];
     error:nil];

    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    NSURLSessionUploadTask *uploadTask;
    uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) 
                      dispatch_async(dispatch_get_main_queue(), ^
                          NSLog(@"Laddar...");
                      );
                   completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) 
                      if (error) 
                          NSLog(@"Error: %@", error);
                       else 
                          NSLog(@"%@ %@", response, responseObject);
                      
                  ];
    [uploadTask resume];

【参考方案1】：

注意 :- 我刚刚使用 AFNetworking 3.0 实现了图片上传服务，

-> 这里 kBaseURL 表示服务器的 Base URL

->serviceName 表示服务名称。

->dictParams 表示需要时给出参数，否则为零。

->image 表示传递你的图像。

注意：- 这段代码是用 NSObject 类编写的，我们已经在我们的项目中应用了。

+ (void)requestPostUrlWithImage: (NSString *)serviceName parameters:(NSDictionary *)dictParams image:(UIImage *)image success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure 

NSString *strService = [NSString stringWithFormat:@"%@%@",kBaseURL,serviceName];
[SVProgressHUD show];

NSData *fileData = image?UIImageJPEGRepresentation(image, 0.5):nil;

NSError *error;
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:strService parameters:dictParams constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 

    if(fileData)
        [formData appendPartWithFileData:fileData
                                    name:@"image"
                                fileName:@"img.jpeg"
                                mimeType:@"multipart/form-data"];
    
 error:&error];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSURLSessionUploadTask *uploadTask;
uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) 

    NSLog(@"Wrote %f", uploadProgress.fractionCompleted);

                                  completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) 
                                      [SVProgressHUD dismiss];
                                      if (error)
                                      
                                          failure(error);
                                      
                                      else
                                      
                                          NSLog(@"POST Response  : %@",responseObject);
                                          success(responseObject);

                                      
                                  ];

[uploadTask resume];

--> 现在申请到我们的项目中。

UIImage *imgProfile = //Pass your image.        


    [WebService requestPostUrlWithImage:@"save-family-member" parameters:nil image:imgProfile success:^(NSDictionary *responce) 

        NSString  *check = [NSString stringWithFormat:@"%@",[responce objectForKey:@"status"]];
        if ([check  isEqualToString: @"1"]) 
           //Image Uploaded. 
        
        else
        
         //Failed to Upload.
        


     failure:^(NSError *error) 
        //Error
    ];
