Rest Post示例（java服务端、python客户端）

　　前提：服务端是现成的，java、springMVC、resttemplate、jboss等；突然有个需要，要在windows上开发一个客户端，作用是定期向服务端上传文件。想了想，如果客户端写一个java程序，势必要求在windows上安装java的运行环境，这样比较麻烦。后来的解决思路是写python的程序，然后打包成exe在windows上执行。以下是Rest Post示例的服务端、客户端代码。

server端代码：

@RequestMapping(value = "/uploadScriptResult")
    public @ResponseBody OperateResult uploadScriptResult(MultipartFile files){
        //public @ResponseBody OperateResult uploadScriptResult(@RequestParam(value="files",required=false) MultipartFile files){
        OperateResult result = new OperateResult();
        try {
            log.info("uploadScriptResult start. ");
            result = uploadFile(files);
        } catch (Exception e) {
            log.error("uploadScriptResult error", e);
            result.setStatus(false);
            result.setMsg(e.getMessage());
        }
        return result;
    }

    private OperateResult uploadFile(MultipartFile file) {
        OperateResult result = new OperateResult();
        log.info("upload file start");
        String basePath = ContextLoader.getCurrentWebApplicationContext().getServletContext().getRealPath("/") + Constants.REMOTE_SCRIPT_TEST_DIR + "execresult/" + getDate() + "/";
        File uploadPath =new File(basePath);
        if(!uploadPath.exists())
            {
            uploadPath.mkdir();
        }
        String name = file.getOriginalFilename();
        name = name + "." + System.currentTimeMillis() + ".execresult.txt";
        String resourceURL = basePath + name;
        try {
            file.transferTo(new File(resourceURL));
            log.info("transfer file To: " + resourceURL + "success!");
            result.setMsg(name);
        } catch (Exception e1) {
            log.error("upload file error! resourceURL=" + resourceURL, e1);
            String msg = "upload file error resourceURL=" + resourceURL + " OriginalFilename: " + file.getOriginalFilename();
            result.setStatus(false);
            result.setMsg(msg);
        }
        return result;
    }

   private String getDate(){
        Date d = new Date();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
        String dateNowStr = sdf.format(d);
        return dateNowStr;
    }

public class OperateResult {
    private Boolean status;
    private String msg;
    public OperateResult(){
        this.status = true;
        this.msg = "";
    }
    public Boolean getStatus() {
        return status;
    }
    public void setStatus(Boolean status) {
        this.status = status;
    }
    public String getMsg() {
        return msg;
    }
    public void setMsg(String msg) {
        this.msg = msg;
    }
}

client端代码：

import urllib
import urllib2
import requests
from poster.encode import multipart_encode
from urllib2 import Request, urlopen, URLError, HTTPError
from poster.encode import multipart_encode
from poster.streaminghttp import register_openers

def uploadFile(filePath, url):
    register_openers()
    datagen, headers = multipart_encode({"files": open(filePath, "rb")})
    request = urllib2.Request(url, datagen, headers)
    response = urllib2.urlopen(request)
    print response.read()

if __name__ == "__main__":
    uploadFile("/home/testResult", "http://192.168.7.144:8888/starott_cloud_client/remotescripttest/uploadScriptResult");
