在.vscode/settings.json中配置网络代理，如：

"http.proxy": "http://xxx:7890",
"http.proxyStrictSSL": false,
"http.proxySupport": "override",
"claudeCode.environmentVariables": [
    {
     "name":"HTTP_PROXY",
     "value":"http://xxx:7890"

    },
    {
     "name":"HTTPS_PROXY",
     "value":"http://xxx:7890"
    }
],
