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);
    }
