Reverse Proxy: Use For AWS IAM/v4 Auth

The program itself contains only the official library

What is Reverse Proxy?

We have some machine(clint want to visit server):

1. Client Machine(CM)
2. Proxy Machine(PM)
3. Server Machine(SM)

Proxy way such as: CM --> PM ---> SM, And Forward Proxy: ** ---> PM --> SM, PM hide the CM (e.g. our http/http/socks proxy). Reverse Proxy: CM ---> PM --> **, PM hide the SM (e.g. our nginx/haprxoy load balancing)

A story:

Li Lei commissioned you to borrow money from Han Meimei. Han Meimei lent you $500, but Han Meimei didn't know it was Li Lei's. you were the Forward Proxy. Hide Client End.

Li Lei want to borrow money from you , Han Meimei lent you $500, you lent to Li Lei, but Li Lei didn't know that money is Han Meimei's, you are the Reverse Proxy. Hide Server End.

Chinese:

李雷委托你跟韩梅梅借钱, 韩梅梅借给你500刀,但是韩梅梅不知道是李雷借的, 你是正向代理.  隐藏客户端

李雷和你借钱, 韩梅梅给了你500刀, 你借给了李雷, 但是李雷不知道钱是韩梅梅的, 你是反向代理. 隐藏服务器端

How to Use?

1.No authentication proxy way:

proxyamd64 --remote=http://www.zhihu.com --local=127.0.0.1:8889 --auth=no

2.AWS authentication proxy way:

proxyamd64 --access-key=1213 --secret-key=131312 --remote=https://search-asdsaddsa.us-east-1.es.amazonaws.com  --local=127.0.0.1:8888

Then you can have a try:

curl 127.0.0.1:8888

If you want to write some other aws service auth you can refer core code:

	.....

	switch *Type {
	case "aws-es":
		AwsConfig.AwsService = "es"    //   Just Modify here
		AwsConfig.AwsRegion = *AWSRegion  // Just Modify here
	default:
		break
	}
	AwsConfig.AwsID = *Key
	AwsConfig.AwsKey = *Secret
	
	.....

	req.ParseForm()
	amzdate, authorization_header := AwsAuthSignature(AwsConfig, getURIPath(req.URL), req.Method, req.URL.Host, req.Form, buf)
	req.Header.Set("X-Amz-Date", amzdate)
	req.Header.Set("Authorization", authorization_header)
	
	.....

Usage of proxyamd64:

  -access-key string
        access key
  -auth string
        auth way: aws-es|no (default "aws-es")
  -aws-region string
