1. Fidhttp://www.aliyun.com/zixun/aggregation/16504.html "What is >dler?"

Fiddler is a free HTTPS network debugger written in C #. English Fiddler is the meaning of the violin, Fiddler-web-debugger, like a violin, can make the front-end development more elegant.

Fiddler is a proxy server to monitor the network data flow of the system. After running the fiddler, it will open 8888 ports locally, the network data flow through the fiddler, we can monitor the HTTPS data flow records, and analysis, and even modify the sent and received data. Fiddler also provides a range of tools to clear IE caching, request Builder, text conversion tools, etc., and is valuable for front-end development work.

2. Download and install the Fiddler installation. NET Framework version 2.0 is free to download fiddler from the official website.

Firefox with fiddler, you can download a plugin: fiddler switch

3. Fiddler interface and Feature List

On the left is the list of data, which distinguishes the data type and state with different icons, and the following is the meaning of the icon: sending the request data to the server is using the HTTP head method in the suspend request during a pause in the call from the server downloading the request for a data back The HTTP connect method should not be used in the return of the body content request. An HTTPS connection channel returns a content type where the content type returned by the image is the content type returned by the picture, and the content type returned by the JavaScript is the contents type that the CSS returns is the XML normal successful return return content for http/300,301,302,303 or 307 Jump return content is http/304: Use local cache return content for a certificate request return content is a server error request by the client, fiddler or server Interrupt Viewer in many forms provided by the viewer, we can view the contents of the data stream. Requests Builder (Request Builder) can create arbitrary data request filter filters that can filter the data flow list on the left, and we can mark, modify, or hide data streams for certain features. The Autoresponse feature, which can be counted as the most useful function of Fiddler, allows us to modify the data returned by the server side, such as making the return HTTP404 or reading the local file as the return content. We will introduce the use of Autoresponse functionality in the example. Text encoding and decoding provides some commonly used text codec conversions. In addition, two data streams can be compared fiddler can save and open the "saz" format of the file, so you can save the data stream to be heard, the next time you reopen the analysis. You can save saz files by using fiddlercap--, a gadget dedicated to recording and saving saz. Saz file can be set password protection, more intimate. Source: http://www.aliued.cn/?p=2567
