訪問taotao-portal服務406問題 - HTTP Status 406 （httpclient調用）

 

解決辦法：

1、查看是否Jackson包是否存在。

2、如果後綴是html是不能響應json數據的。需要修改後綴名。

3、POST的編碼亂碼

 

4、正確的用例結果：

1、單元測試用例 

    @Test
    public void doPost() throws Exception {
        CloseableHttpClient httpClient = HttpClients.createDefault();

        //創建一個post對象
        HttpPost post = new HttpPost("http://localhost:8082/httpclient/post.html");
        //執行post請求
        CloseableHttpResponse response = httpClient.execute(post);
        String string = EntityUtils.toString(response.getEntity());
        System.out.println(string);
        response.close();
        httpClient.close();

    }

 

2、測試接口

    @RequestMapping(value = "/httpclient/post", method = RequestMethod.POST)
    @ResponseBody
    public TaotaoResult testPost(String username, String password) {
        String result = "username:" + username + "\tpassword:" + password;
        System.out.println(result);
        return TaotaoResult.ok();
    }
