在Windows窗体应用程序中使用Restful Webservice

Question

我正在尝试在Windows窗体应用程序中使用用PHP编写的restful webservice（返回JSon响应）。它给出了一些回复的html

此网站需要使用Javascript工作，请在您的浏览器中启用Javascript或使用支持Javascript的浏览器

网络服务

#!/bin/bash 
mysql --host=localhost --user=root --password=111111
mysql 1<< EOF
INSERT INTO
table1(id)
SELECT MAX(id) + 1 FROM table1;
EOF

C＃代码：点击按钮我发出请求，但意外响应了一些html

//Slim based php webservice   
 $app->get(
        "/books",
        function () use ($app) {
           $books[0] = array(
                    "id" => "1",
                    "name" => "lifeGoesOn" ,
                    "author" => "nomibhaii"
                );
            $books[1] = array(
                    "id" => "2",
                    "name" => "lifesaysgoodbye" ,
                    "author" => "nomibhaii"
                );
            $app->response()->header("Content-Type", "application/json");
            return json_encode($books);
        }
    )

;

我收到此回应回复：

private void button1_Click(object sender, EventArgs e)
        {
            string response = null;
            using (var client = new WebClient())
            {
                response = client.DownloadString("http://nomi.byethost5.com/api/index.php/books");
                if (response != "")
                {
                    resultBox.Text = response;
                }

            }

        }
