We recommend updating whistle and Node to ensure that you receive important features, bugfixes and performance improvements. Some versions of Node have bugs that may cause whistle to not work properly, for detail see the issue: #231
whistle
whistle is a cross-platform web debugging tool based on Node.js.
It features the following:
- offer HTTP proxying
- capture, replay or compose requests of HTTP, HTTPS, WebSocket and TCP.
- manipulate http request and response by configing hosts, or patterns like domain, path, regular expression, wildcard characters, wildcard path, etc.
- offer build-in mobile debugging mode
If the aboves can't satisfy your requirements, you can also use plugins to extend its capabilities.
The specific functions are as follows:
Manipulations to http request and response in whistle can be achieved as a Rule looks like:
pattern operatorURI
Description:
pattern is an expression to match the target request url. You can write patterns in different forms including domain, path, regular expression, wildcard, and so on.
# matching domain www.example.com # domain with port www.example.com:6666 # domain with protocol, supporting http, https, ws, wss, tunnel http://www.example.com # matching path, supporting protocol, port www.example.com/test https:/www.exapmle.com/test https:/www.exapmle.com:6666/test # matching regular expression /^https?://www\.example\.com\/test/(.*)/ referer://http://www.test.com/$1 # matching wildcard ^www.example.com/test/*** referer://http://www.test.com/$1
For more details, please visit Pattern Matching
operatorURI is the corresponding operation, made up of opProtocol and opValue:
opProtocol represents the kind of operation, e.g.# host:setting requested server IP pattern host://opValue # file:using the local file to replace pattern file://opValue
opValue represents the parameters of the specific operation, e.g.
# host:setting requested server IP pattern host://127.0.0.1:6666 # or pattern 127.0.0.1:6666 # file:using the local file to replace pattern file:///User/test/dirOrFile # or pattern /User/test/dirOrFile pattern file://E:\test\dirOrFile # or pattern E:\test\dirOrFile
For more details, please visit operation value
The position of pattern and operatorURI can be swapped in most situations while the combination mode is also supported. For more details, please visit configuration mode

cofigure hosts
Specify the ip of www.ifeng.com:
www.ifeng.com 127.0.0.1 # or 127.0.0.1 www.ifeng.com
Specify the ip and port of www.ifeng.com to forward http request to local port 8080. In this way, we can visit the local website just as online when the developing port is not 80:
# www.ifeng.com 127.0.0.1 www.ifeng.com 127.0.0.1:8080 # or 127.0.0.1:8080 www.ifeng.com
We can also replace the real IP (or domain) and port with any domain without port:
www.ifeng.com host://www.qq.com:8080 # or host://www.qq.com:8080 www.ifeng.com
For more details, please visit Pattern Matching
local files replacing
Replace the response with content in local file system, which is frequently used during web developing.
# Mac or Linux
www.ifeng.com file:///User/username/test
# or www.ifeng.com file:///User/username/test/index.html
# Both '\' and '/' can be used as path separator for Widows
www.ifeng.com file://E:\xx\test
# or www.ifeng.com file://E:\xx\test\index.html
http://www.ifeng.com/ will try to load /User/username/test
first. If the former dosen't exist, the file /User/username/test/index.html
will be loaded. For neither exists, it returns 404.
To replace jsonp request, you can refer to tpl
