HttpPost请求将json作为请求体传入的简单处理方法

***********************************************************

通过httpclient的post方法发送json参数进行接口测试。借鉴知乎上“云层”的提供的方法。

把要发送的json作为字符串传入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;
}

我的测试代码示例：

public static void main(String[] args) {
    //测试公司的API接口，将json当做一个字符串传入httppost的请求体
    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);
        //设置请求头
        post.setHeader("Content-Type", "application/json");
        String body = "{\"Key\": \"\",\"Secret\": \"\"}";
        //设置请求体
        post.setEntity(new StringEntity(body));
        //获取返回信息
        HttpResponse response = client.execute(post);
        result = response.toString();
    } catch (Exception e) {
        System.out.println("接口请求失败"+e.getStackTrace());
    }
    System.out.println(result);
}
