Httpclient获取网络JSON get可以而post出错

[一分逍遥]

从一个数据开放平台获取JSON（天气）
这是get的代码

HttpClient  httpClient=new DefaultHttpClient();
HttpGet  httpGet=new HttpGet(
"http://route.showapi.com/9-7"+"?"+"area=北京&areaid=&month=201606&showapi_appid=22661&showapi_sign=fa597c55d97d435ebbc67bc9dd45fe83");
HttpResponse response = httpClient.execute(httpGet);
int code = response.getStatusLine().getStatusCode();
if(code== HttpStatus.SC_OK){
HttpEntity entity = response.getEntity()
String s1 = EntityUtils.toString(entity, "utf-8");
System.out.println(s1);
}

这个是post的

HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost=new HttpPost("http://route.showapi.com/9-7");
        
        List<BasicNameValuePair>  list=new ArrayList<BasicNameValuePair>();
        list.add(new BasicNameValuePair("showapi_sign","fa597c55d97d435ebbc67bc9dd45fe83"));
        list.add(new BasicNameValuePair("showapi_appid","22661"));
        list.add(new BasicNameValuePair("area","北京"));
        list.add(new BasicNameValuePair("month","201607"));
    
        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list);
        httpPost.setEntity(entity);

        HttpResponse response = httpClient.execute(httpPost);
        if(response.getStatusLine().getStatusCode()== HttpStatus.SC_OK){
            HttpEntity entity1 = response.getEntity();
            String s1 = EntityUtils.toString(entity1, "utf-8");
            System.out.println(s1);
        }

get得到的数据正确
post得到
{"showapi_res_code":-3,"showapi_res_error":"系统异常。读取错误。","showapi_res_body":{}}

应该是这个网站的问题

[一分逍遥]

追问一个问题吧 api23 httpclient不是弃用了嘛，就学习一下HttpURLConnection 问一下，HttpURLConnection post怎么添加请求参数 类似这样的： 网址+ ?showapi_appid=22587&type=&name=syz &showapi_sign=92ebb9944c5b4a43bd308b3facb6a3d8 HttpClient可以用这个方法，post.setEntity(new UrlEncodedFormEntity(list)) 那HttpURLConnection 应该怎么办啊，查了好久实在没找到干货，求大神帮助

应该是接口只支持GET请求吧

好像是的，那个数据平台有点问题，有的api就都支持，有的用post就出问题。 大神顺便回复一下2楼那个问题吧，有好的学习帖子贴一下也好
