                          mResponseCallback.onException(

                      }

                          mResponseCallback.onResponse(response.body()!!.string())
     
    
   

    

     

    
    

     

                      }
     
    
   

    

     

    
    

     

                  })
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

              } 
      catch (e1: IOException) {
     
    
   

    

     

    
    

     

                  e1.printStackTrace()
     
    
   

    

     

    
    

     

              }
     
    
   

    

     

    
    

     

          }
     
    
  

 代码很简单,我先介绍一下参数

uploadFilePath :文件的上传地址,绝对地址,注意安卓10.0的文件权限

Uri:服务器接收文件的地址

mMediaType:资源类型,这个可以百度得到,比如视频是 video/mp4

mResponseCallback:是一个回调

   

    

     

      

     
     

      

       interface ResponseCallback {
      
     
    

     

      

     
     

      
    
       fun onResponse(string: String)
      
     
    

     

      

     
     

      
    
       fun onError(httpCode: Int?, errorBody: String?, throwable: Throwable?)
      
     
    

     

      

     
     

      
    
       fun onException(string: String)
      
     
    

     

      

     
     

      
    
       fun UploadProBar()
      
     
    

     

      

     
     

      

       }
      
     
   

这个类看你们自己的交互可加可不加!

注意:我在使用这个类传大文件的时候出现通道破裂问题,但是小文件不会,这个问题是因为服务器默认限制了上传文件的大小 

扩展:有些服务器会有token一说,那么如果有token的话,我们的配置就是这样的:

request = Request.Builder()
        .url(Uri)
        .post(body)
        .header(TokenName, Token) //后台所需要的token
        .build()

 tokenName是token的别名,Token就是服务器需要的token,看情况而定!
