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");
