介绍 PostMethod请求注意两点:
HttpClient HttpClient =, new HttpClient ();
,String host =,(字符串),BaseConfig.get (“host");
,String port =,(字符串),BaseConfig.get (“port");
,httpClient.getHostConfiguration () .setProxy(主机,Integer.valueOf(港口));
,PostMethod PostMethod =, new PostMethod (applyurl);
,JSONObject JSONObject =, new JSONObject ();
,jsonObject.put (“name" user.getName ());
,jsonObject.put (“phone" user.getPhone ());
,jsonObject.put (“provinceCode" user.getProvinceCode ()),,
,jsonObject.put (“cityCode" user.getCityCode ()),,
,jsonObject.put (“buyModelCode" user.getBuyModelCode ()),,
,jsonObject.put (“dealerCode" user.getDealerCode ()),,
,jsonObject.put (“url"“http: xxx"),,
,String toJson =, jsonObject.toString ();
,RequestEntity se =, new StringRequestEntity (toJson ,“应用程序/json",,“UTF-8");
,postMethod.setRequestEntity (se);
,postMethod.setRequestHeader (“Content-Type",“应用程序/json");
,//默认的重试策略
,postMethod.getParams () .setParameter (HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler ());
,postMethod.getParams () .setParameter (HttpMethodParams.SO_TIMEOUT, 5000);//设置超时时间
,int httpStatus =, hc.executeMethod (postMethod);
,String str=postMethod.getResponseBodyAsString ();
,T.console (“str - - - - - - -:“+ str); //HttpClient发起请求
public static String sendUrlFile (String url, String jsonstr), {,
,String result =,““
try {大敌;
,HttpClient HttpClient =, new HttpClient ();
,PostMethod post =, new PostMethod (url),,
,FilePart FilePart =, new FilePart (“file",, new 文件(“/根/桌面/文档/记录.txt"));
,filePart.setCharSet (“utf-8");,
,post.getParams () .setParameter (HttpMethodParams.HTTP_CONTENT_CHARSET,“utf-8");
,//数部分组装需要传第的参数和文件等
,部分[]parts =, {new StringPart (“username" jsonstr ,,“utf-8"), filePart};
,MultipartRequestEntity entity =, new MultipartRequestEntity(部分,post.getParams ());
,post.setRequestEntity(实体);
,int code =, httpclient.executeMethod (post);
,//拿到响应结果=,,result new 字符串(post.getResponseBody (),“UTF-8");
,//可释放连接
,post.releaseConnection (),,
,return 结果;
,}catch (HttpException h), {
,LOGGER.error (“cause textbox:“, +, h.getMessage ()),,
,}catch (Exception i), {
,LOGGER.error(“发送请求错误:,url cause IOException:“, +, i.getMessage ());
}大敌;
,return ““;
}//接收请求服务器端,参数需要和发送端一致 @ResponseBody
@RequestMapping (value =,/登录)
public JsonResult revice (@RequestParam(“文件”),MultipartFile 文件,@RequestParam(“用户名”)String 用户名),throws IOException {
InputStream 拷贝=,file.getInputStream ();
OutputStream out =, new FileOutputStream(“/根/桌面/ok.txt");
时间=byte [], bs new 字节[1024];
int 兰;
而(1,!=,(len =, (in.read (bs)))) {
out.write (bs);
}
JsonResult json =, new JsonResult ();
System.out.println ();
json.setResult (“ok”);
return json;
}
这期内容当中小编将会给大家带来有关怎么在java中利用HttpClient PostMethod对json数据进行提交,文章内容丰富且以专业的角度为大家分析和叙述,阅读完这篇文章希望大家可以有所收获。
PostMethod请求注意两点:
1,如果使用的是公司的服务器,设置好代理和端口。
2,如果url中有空格,需要使用% 20进行转义。
贴一下我的代码,给不会还没用过不会PostMethod请求的萌新们…
代码很简单,就不过多解释了,最后感谢这个坑爹的文档,又让我学到了一招。
<>强补充:利用HttpClient& PostMethod上传文件和请求参数
我就废话不多说了,大家还是直接看代码吧~
上述就是小编为大家分享的怎么在java中利用HttpClient PostMethod对json数据进行提交了,如果刚好有类似的疑惑,不妨参照上述分析进行理解。如果想知道更多相关知识,欢迎关注行业资讯频道。
