HttpPost請求將json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。

把要發送的json作為字符串傳入body即可

 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;
}

我的測試代碼示例：

public static void main(String[] args) {
    //測試公司的API接口，將json當做一個字符串傳入httppost的請求體
    String result = null;
    HttpClient client = HttpClients.createDefault();
    URIBuilder builder = new URIBuilder();
    URI uri = null;
    try {
        uri = builder.setScheme("http")
                  .setHost("xxx.xxx.xxx.xxx:xxxx")
                  .setPath("/api/authorize/login")
                  .build();
        
        HttpPost post = new HttpPost(uri);
        //設置請求頭
        post.setHeader("Content-Type", "application/json");
        String body = "{\"Key\": \"\",\"Secret\": \"\"}";
        //設置請求體
        post.setEntity(new StringEntity(body));
        //獲取返回信息
        HttpResponse response = client.execute(post);
        result = response.toString();
    } catch (Exception e) {
        System.out.println("接口請求失敗"+e.getStackTrace());
    }
    System.out.println(result);
}
