How to fixed set the request's mode to 'no-cors'?
提问by Neel Shah
I am currently using yahoo weather api to fetch weather data. I am getting below error. Please help.
我目前正在使用雅虎天气 api 来获取天气数据。我得到低于错误。请帮忙。
Access to fetch at 'https://weather-ydn-yql.media.yahoo.com/forecastrss?location=sunnyvale,ca&format=json' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: 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.
从源“ http://localhost:3000”访问“ https://weather-ydn-yql.media.yahoo.com/forecastrss?location=sunnyvale,ca&format=json”已被 CORS 政策阻止：响应预检请求未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。如果不透明响应满足您的需求，请将请求的模式设置为“no-cors”以在禁用 CORS 的情况下获取资源。
