关于多张图片上传的name修复问题(紧急)!!!

[shang1219178163]

• (NSURLSessionTask )uploadImagesWithURL:(NSString )URL parameters:(id)parameters name:(NSString )name images:(NSArray<UIImage > )images fileNames:(NSArray<NSString > )fileNames imageScale:(CGFloat)imageScale imageType:(NSString )imageType progress:(PPHttpProgress)progress success:(PPHttpRequestSuccess)success failure:(PPHttpRequestFailed)failure ; 此方法中的name会传给下边方法,
• (void)appendPartWithFileData:(NSData )data name:(NSString )name fileName:(NSString )fileName mimeType:(NSString )mimeType 我们后台是PHP,同事反馈说多张图片name不能相同,不然只能接收到一张图片(图片会覆盖),建议将name:(NSString )name改为建议将name:(NSArray )name;还有问题是你通过一个name可以上传多张图片的话,能告诉我后台接收思路吗?我可以反馈给接口同事,共同进步. -------------------------------------------------------------------------------用代码改变世界.

但是name必须写死为"file", 是指服务器接收的数据类型. 请问有其他解决办法吗

`#pragma mark - 上传多张图片 多个参数

• (NSURLSessionTask )uploadImagesWithURL:(NSString )URL parameters:(id)parameters names:(NSArray )names images:(NSArray<UIImage > )images fileNames:(NSArray<NSString > )fileNames imageScale:(CGFloat)imageScale imageType:(NSString )imageType progress:(PPHttpProgress)progress success:(PPHttpRequestSuccess)success failure:(PPHttpRequestFailed)failure { NSURLSessionTask *sessionTask = [_sessionManager POST:URL parameters:parameters constructingBodyWithBlock:^(id _Nonnull formData) {

  for (NSUInteger i = 0; i < images.count; i++) {
      // 图片经过等比压缩后得到的二进制文件
      NSData *imageData = UIImageJPEGRepresentation(images[i], imageScale ?: 1.f);
      // 默认图片的文件名, 若fileNames为nil就使用
  
      NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
      formatter.dateFormat = @"yyyyMMddHHmmss";
      NSString *str = [formatter stringFromDate:[NSDate date]];
      NSString *imageFileName = NSStringFormat(@"%@%ld.%@",str,i,imageType?:@"jpg");
  
      [formData appendPartWithFileData:imageData
                                  name:[names objectAtIndex:i]
                              fileName:fileNames ? NSStringFormat(@"%@.%@",fileNames[i],imageType?:@"jpg") : imageFileName
                              mimeType:NSStringFormat(@"image/%@",imageType ?: @"jpg")];
  }

  } progress:^(NSProgress _Nonnull uploadProgress) { //上传进度 dispatch_sync(dispatch_get_main_queue(), ^{ progress ? progress(uploadProgress) : nil; }); } success:^(NSURLSessionDataTask _Nonnull task, id _Nullable responseObject) {

  if (_isOpenLog) {PPLog(@"responseObject = %@",responseObject);}
  [[self allSessionTask] removeObject:task];
  success ? success(responseObject) : nil;

  } failure:^(NSURLSessionDataTask _Nullable task, NSError _Nonnull error) {

  if (_isOpenLog) {PPLog(@"error = %@",error);}
  [[self allSessionTask] removeObject:task];
  failure ? failure(error) : nil;

  }];

  // 添加sessionTask到数组 sessionTask ? [[self allSessionTask] addObject:sessionTask] : nil ;

  return sessionTask; }` 完美解决
