Two: HttpResponse common properties

2. status_code：返回的HTTP响应状态码。
3. content_type：返回的数据的MIME类型，默认为text/html。浏览器会根据这个属性，来显示数据。
                        如果是text/html，那么就会解析这个字符串，如果text/plain，那么就会显示一个纯文本。
                        常用的Content-Type如下：
        text/html（默认的，html文件）
        text/plain（纯文本）
        text/css（css文件）
        text/javascript（js文件）
        multipart/form-data（文件提交）
        application/json（json传输）
        application/xml（xml文件）
