HttpPost請求將帶有數組json格式數據作為請求體傳入的簡單處理方法

通過httpclient的post方法發送json參數進行接口測試。借鑒知乎上“雲層”的提供的方法。

public static String sendHttpPost(String url, String body) throws Exception {
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("Content-Type", "application/json");
httpPost.setEntity(new StringEntity(body));
CloseableHttpResponse response = httpClient.execute(httpPost);
System.out.println(response.getStatusLine().getStatusCode() + "\n");
HttpEntity entity = response.getEntity();
String responseContent = EntityUtils.toString(entity, "UTF-8"); 
System.out.println(responseContent);
response.close();
httpClient.close();
return responseContent;
}

其中httpPost.setEntity(new StringEntity(body));body部分是JSON數據格式，可以不是定長數據，可以根據需求定義成數組形式，如下：

 

{
   "splineList" : 
   [
      {
         "Points" : 
         {
            "Pos" : [
               {
                  "Xasis" : 1.66156307383845,
                  "Yasis" : 132.2036349238536
               },
               {
                  "Xasis" : 2.598720236773715,
                  "Yasis" : 186.8623164821516
               },
               {
                  "Xasis" : 3.598720236773715,
                  "Yasis" : 186.8623164821516
               }
            ]
         }
      },
      {
         "Points" : 
         {
            "Pos" : [
               {
                  "Xasis" : 4.66156307383845,
                  "Yasis" : 132.2036349238536
               },
               {
                  "Xasis" : 5.598720236773715,
                  "Yasis" : 186.8623164821516
               }
            ]
         }
      },
      {
         "Points" : 
         {
            "Pos" : [
               {
                  "Xasis" : 6.66156307383845,
                  "Yasis" : 132.2036349238536
               },
               {
                  "Xasis" : 7.598720236773715,
                  "Yasis" : 186.8623164821516
               },
               {
                  "Xasis" : 17.598720236773715,
                  "Yasis" : 186.8623164821516
               },
               {
                  "Xasis" : 27.598720236773715,
                  "Yasis" : 186.8623164821516
               },
               {
                  "Xasis" : 37.598720236773715,
                  "Yasis" : 186.8623164821516
               }
            ]
         }
      }
   ]
}

 

其中，splineList有多個Points組成，Points又由多個Xasis，Yasis坐標組成.
