Close golang proxy

In the process of developing using Go language, we often use proxies to access some websites or services that cannot be directly connected. However, in some cases, we need to turn off the proxy settings of the Go language to avoid some problems. This article will introduce how to turn off the proxy of Go language.

Why do you need to turn off the proxy?

Before using the proxy, we need to understand why we need to turn off the proxy. Here are some possible reasons:

1. Trust issues: Sometimes we install some proxy services, but we don't trust its source. Turning off the proxy avoids this risk.
2. Unstable network: Proxies may cause unstable network connections. Turning off the proxy can avoid this problem.
3. Speed ​​issue: Accessing the website through a proxy may cause slowdowns. Turning off the proxy can increase access speed, thereby improving development efficiency.

How to turn off the proxy?

Turning off the agent is mainly divided into the following two situations:

1. Turn off the system agent

In the operating system, we can turn off the system agent through the following methods ：

• Windows system: In the "Internet Properties" menu, select the "Connection" tab, then click "LAN Settings", and finally clear the "Use a proxy server" check box.
• macOS system: In the "Network Preferences" panel, select the current network connection, then select "Advanced Settings", then click the "Proxy" tab, and finally uncheck "Use web proxy (HTTP)" and the "Use a secure web proxy (HTTPS)" checkbox.
• Linux system: Use the following command in the terminal to turn off the proxy settings:

export http_proxy=
export https_proxy=

2. Use the environment variable of the Go language

Use Go When developing the language, we can turn off the proxy by setting environment variables. Here's how to set environment variables:

• In a terminal, use the following command to set an environment variable:

export http_proxy=
export https_proxy=

• In code, use the following method to Set environment variables:

os.Setenv("http_proxy", "")
os.Setenv("https_proxy", "")

If you cannot turn off the proxy immediately and do not want to use environment variables in your code, you can use the Dial method in the golang.org/x/net/proxy package, which can be found in Correctly connect to the service under proxy settings, no need to manually set environment variables. The usage method is as follows:

dialer, err := proxy.SOCKS5("tcp", "127.0.0.1:1080", nil, proxy.Direct)
httpClient := &http.Client{Transport: &http.Transport{Dial: dialer.Dial}}
httpClient.Get("http://example.com")

Summary

Turning off the agent may not be a common operation, but in some specific cases, turning off the agent can help us avoid some problems and improve development efficiency. This article describes how to turn off the proxy settings of the Go language. I hope it will be helpful to you.
