java後臺模擬傳送post請求,get也請用此種方式避免編碼問題


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

        //設定請求的方法型別
        httpURLConnection.setRequestMethod("POST"
); //設定請求的內容型別 httpURLConnection.setRequestProperty("Content-type", "application/x-www-form-urlencoded"); //設定傳送資料 httpURLConnection.setDoOutput(true); //設定接受資料 httpURLConnection.setDoInput(true); //傳送資料,使用輸出流 OutputStream outputStream = httpURLConnection.getOutputStream(); //傳送的soap協議的資料
// String requestXmlString = requestXml("北京"); //String content = "user_id="+ URLEncoder.encode("13846", "gbk"); //傳送資料 outputStream.write(content.getBytes()); //接收資料 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; }

字串轉為json物件並獲取其中屬性

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

如果獲得的jsonobject的裡面是陣列

則:

@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); // 遍歷 jsonarray 陣列,把每一個物件轉成 json 物件
                System.out.println(job.get("pdtname"));

            }


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

        return null;
    }
