AFN做是最簡單的。

NSURL *fileURL = [NSURL fileURLWithPath:zipPath];//zipPath是zip文件路徑，是NSString類型的
NSURL *url = [NSURL URLWithString:@"http://..."];

AFHTTPSessionManager *client = [[AFHTTPSessionManager alloc] initWithBaseURL:url];
client.responseSerializer = [AFJSONResponseSerializer serializer];
client.requestSerializer.timeoutInterval = 30.0f;
NSURLSessionDataTask *task = nil;

//如果有參數(shù)需要拼接到url上，可以在POST：寫字符串
task = [client POST:nil parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
  NSURL *url = fileURL;
            
  NSError *error = nil;
  [formData appendPartWithFileURL:url
                                       name:@"file"
                                      error:&error];
            
   if (error) {
     DGJLogError(@"uploadFileLog call appendPartWithFileURL error! Error is %@",error);             
   }
} progress:nil
                    success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                        if (responseObject) {
                            NSDictionary *dicContent = responseObject;
                            NSInteger status = [[dicContent objectForKey:@"status"] intValue];
                     
                            if (status == 0 ) {
                          
                                
                            } 
                           
                        }
                        
                    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                        NSLog(@"error = %@",error);
                    }];
