# Test proxy availability

> It supports two verification methods: whitelist and username and password. It is recommended that you test it on this machine first. After the test is OK, you can use it normally.

## 1.Proxy verification

* Whitelist your machine's IP
* Set the username and password when making a request (according to the request library settings used, the username and password used for proxy verification can be obtained on the order details page)

## 2.Command line test

If your program runs on Linux, we highly recommend that you test the availability of the proxy server through commands under the command line `curl`before programming.

> For example, your username is `username`, password is `password`, Proxy Host and Proxy Port are `0hmg5j581x.g.go2proxy.com:16888`

You can execute the following command to test the proxy availability：

<CodeGroup>
  ```python HTTP Proxy theme={null}
  #Enter the username and password
  curl -v "https://www.google.com/" -x username:password@0hmg5j581x.g.go2proxy.com:16888

  #Enter the Proxy-Authorization
  curl -v -H "Proxy-Authorization: Basic bXl1c2VybmFtZTpteXBhc3N3b3Jk" "https://www.google.com/" -x 0hmg5j581x.g.go2proxy.com:16888
  ```

  ```python SOCKS Proxy theme={null}
  #Enter the username and password
  curl -v "https://www.google.com/" --socks5 username:password@0hmg5j581x.g.go2proxy.com:16888
  ```
