java后台模拟发送post请求,get也请用此种方式避免编码问题

    public static String geturl1(String geturl,String content) throws Exception {
        //请求的webservice的url
        URL url = new URL(geturl);
        //创建http链接
        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

        //设置请求的方法类型
        httpURLConnection.setRequestMethod("POST");

        //设置请求的内容类型
        httpURLConnection.setRequestProperty("Content-type", "application/x-www-form-urlencoded");

        //设置发送数据
        httpURLConnection.setDoOutput(true);
        //设置接受数据
        httpURLConnection.setDoInput(true);

        //发送数据,使用输出流
        OutputStream outputStream = httpURLConnection.getOutputStream();
        //发送的soap协议的数据
        //    String requestXmlString = requestXml("北京");

        //String content = "user_id="+ URLEncoder.encode("13846", "gbk");

        //发送数据
        outputStream.write(content.getBytes());

        //接收数据
        InputStream inputStream = httpURLConnection.getInputStream();
        BufferedReader in = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));  
        StringBuffer buffer = new StringBuffer();  
        String line = "";  
        while ((line = in.readLine()) != null){  
            buffer.append(line);  
        }  
        String str = buffer.toString();  


        return str;
    }

字符串转为json对象并获取其中属性

String addrJson = GnthkUtil.geturl1();
JSONObject jobjectaddr =  JSON.parseObject(addrJson);
            String addr=jobjectaddr.getJSONObject("result").getString("formatted_address");

如果获得的jsonobject的里面是数组

则:

@RequestMapping("/toProduct")
    public String toProduct() {
        try {
            String addrJson = GnthkUtil.geturl("http://xxxxxxxxx", "");

            JSONObject jsonObject =  JSON.parseObject(addrJson);
            JSONArray array = jsonObject.getJSONArray("result");
            String string = jsonObject.getJSONArray("result").toJSONString();


            for(int i=0;i<array.size();i++){
                JSONObject job = array.getJSONObject(i); // 遍历 jsonarray 数组，把每一个对象转成 json 对象
                System.out.println(job.get("pdtname"));

            }


        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return null;
    }
