chrome with https proxy

If you turned on the global system proxy, when you visit websites based on https, you'll get NET::ERR_CERT_AUTHORITY_INVALID error, due to the proxyman using self-signed tls certificates, which chrome does not validate for security reason.

• Second, typing the following 12 characters: thisisunsafe on keyboard, yeah, there's not any reaction, just like typing a password on a linux terminal.

Rules usages

Redirect

Each Redirect rule is split by a line and divided into two parts by spaces, the first part being the regex to be matched and the second part being the final address to be redirected.

example

https://proxyhttpbin.org/(.*) https://httpbin.org/$1

Delay

The format is as same as Redirect rule, the difference is the second part is the delaying milliseconds.

example

# the-uri delaying-milliseconds
https://uri.com 200

Response

The format is as same as Redirect rule, the difference is the second part is the Value File name. Under the hood, the Response rule will find the file which named the second part in value files, then parsing the file content as the response of this request.

https://uri.com uri-response-example

Value files

The first line is http version and status code. Then the next parts is the response headers until the empty line appear. After the empty line, the parts is response body.
