Fiddler是一个http协议调试代理工具，它能够记录并检查所有你的电脑和互联网之间的http通讯，设置断点，查看所有的“进出”Fiddler的数据（指cookie,html,js,css等文件）。 Fiddler 要比其他的网络调试器要更加简单，因为它不仅仅暴露http通讯还提供了一个用户友好的格式(Fiddler is a http protocol debugging agent tool that logs and checks all http traffic between your computer and the Internet, sets breakpoints, and views all "in and out" Fiddler data (referring to files such as cookie,html,js,css). Fiddler is simpler than other network debuggers because it not only exposes http traffic but also provides a user-friendly format)
