用java pyhont通过HTTP协议传输文件流

// 代码网上抄的 忘记链接了 抱歉哈
package upload;

    private static void upLoadByCommonPost(String uploadUrl) throws IOException {

        URL url = new URL(uploadUrl);

再来个python的,用到了poster模块下载地址戳这

1# -*- coding: utf-8 -*-

import urllib2

import urllib 

 from poster.encode import multipart_encode
 from poster.streaminghttp import register_openers

      params = {'uploadfile': open(formvalue['file'], "rb")}

2     datagen, headers = multipart_encode(params)

3     request = urllib2.Request(url, datagen, headers)

4     return urllib2.urlopen(request).read().decode("utf_8_sig")

 

服务器代码PHP的

<?php

    var_dump($_FILES);

    if (//($_FILES["type"] == "image/gif")

        //|| ($_FILES["type"] == "image/jpg")

        //|| ($_FILES["type"] == "image/jpeg")

         ($_FILES['uploadfile']["size"] < 200000)){

        if ($_FILES['uploadfile']["error"]>0){

            echo "Error: ".$_FILES['uploadfile']["error"]."<br>";

        }

        else {

            echo "Upload: ". $_FILES['uploadfile']["name"]."<br>";

            echo "Type:".$_FILES['uploadfile']["type"]."<br>";

            echo "Size:".($_FILES['uploadfile']["size"]/1024)."kB<br>";

            echo "Stored in: ".$_FILES["tmp_name"];

        

            if (file_exists("upload/".$_FILES['uploadfile']["name"]))

            {

                echo $_FILES['uploadfile']["name"]." already exists";

            }

            else

            {

                move_uploaded_file($_FILES['uploadfile']["tmp_name"],"upload/".$_FILES['uploadfile']["name"]);

                echo "Stored in: "."upload/".$_FILES['uploadfile']["name"];

            }

        }

    }

    else {

        echo "Invalid file";

    }
