问题描述
我正在构建一个扩展，并且仅在 azure devops 服务器上遇到 workItemIcons api 端点的问题，它适用于 azure devops 服务。我要达到的终点是 http://...../DefaultCollection/_apis/wit/workItemIcons。我在本地运行扩展时遇到以下错误，但即使在已发布的版本上也会出现相同类型的错误。
Access to fetch at 'http://...../DefaultCollection/_apis/wit/workItemIcons' from origin 'http://localhost:5500' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs,set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
我认为扩展范围很好
"vso.graph","vso.identity","vso.project","vso.profile","vso.work_full","vso.analytics","vso.work"
],```
We're using the `azure-devops-extension-api` package.
解决方法
您可以尝试以下方法：
-
将
Access-Control-Allow-Origin标头添加到您的回复中。例如：
res.setHeader('Access-Control-Allow-Origin','*'); -
通过将
mode设置为no-cors来绕过 CORS 安全机制。例如：
fetch('http://...../DefaultCollection/_apis/wit/workItemIcons',{ mode: 'no-cors' });
