文本数据返回
GoFrame中通过以下方法返回文本数据到客户端：
func (r *Response) Write(content ...interface{})
func (r *Response) WriteExit(content ...interface{})
func (r *Response) Writef(format string, params ...interface{})
func (r *Response) WritefExit(format string, params ...interface{})
func (r *Response) Writeln(content ...interface{})
func (r *Response) WritelnExit(content ...interface{})
func (r *Response) Writefln(format string, params ...interface{})
func (r *Response) WriteflnExit(format string, params ...interface{})
以上方法中，带有Exit的表示执行完响应之后就退出本次请求，不再执行后面的内容。带有ln的表示会在响应内容的末尾追加换行符。
以上方法用于向客户端响应文本内容。内容格式为text/html或text/plain，参数可以是任意数据类型，非字符串类型通常会将内容进行json转为字符串后返回到客户端。
如果提供参数为文本，可以是普通文本也可以是HTML文本。
响应简单文本
req.Response.Write("锦瑟无端五十弦")
响应简单HTML
req.Response.Write("<h1>春蚕到死丝方尽</h1>")
响应复杂HTML
