配置HTTP代理后Git正常但go mod tidy无法下载Go模块，如何解决？

问题描述

我尝试通过HTTP代理下载Go包，已编辑.gitconfig文件，配置内容如下：

[http]
        proxyAuthMethod = basic
        sslVerify = false
        proxy = http://mydomain\username:passwd@myproxy:8080
[credential "http://myproxy:8080"]
        provider = generic
[https]
        proxyAuthMethod = basic
        sslVerify = false
        proxy = http://mydomain\username:passwd@myproxy:8080

通过Git克隆仓库可正常工作（执行git clone https://github.com/ClickHouse/clickhouse-go.git -v成功），日志如下：

$ git clone https://github.com/ClickHouse/clickhouse-go.git -v
Cloning into 'clickhouse-go'...

但执行go mod tidy添加Go模块时出现如下错误：

PS C:\Users\user\go\src> go mod tidy
go: finding module for package github.com/ClickHouse/clickhouse-go/v2
main imports
        github.com/ClickHouse/clickhouse-go/v2: module github.com/ClickHouse/clickhouse-go/v2: Get "https://proxy.golang.org/github.com/%21click%21house/clickhouse-go/v2/@v/list": proxyconnect tcp: dial tcp: lookup http: no such host

解决方案

Go模块的代理配置与Git独立，需单独配置Go环境变量适配代理：

设置HTTP/HTTPS代理环境变量
临时生效（重启终端后需重设），在PowerShell执行：
```
$env:HTTP_PROXY="http://mydomain\username:passwd@myproxy:8080"
$env:HTTPS_PROXY="http://mydomain\username:passwd@myproxy:8080"
```
若需永久生效，直接在系统环境变量中添加HTTP_PROXY和HTTPS_PROXY，值与上述一致。
关闭Go模块SSL验证（按需）
因Git已关闭SSL验证，Go模块需同步设置：
```
$env:GOSSLNOVERIFY="1"
```
永久生效同样添加至系统环境变量。
检查代理地址格式
注意代理地址中的反斜杠\，部分环境需用双反斜杠\\或正斜杠替换，确保域名+用户名的组合能被正确解析。
切换Go模块代理源（可选）
若默认proxy.golang.org访问异常，可更换为其他代理源：
```
go env -w GOPROXY=https://goproxy.io,direct
```

完成配置后重新执行go mod tidy即可正常下载模块。
