问题
I am currently using yahoo weather api to fetch weather data. I am getting below error. Please help.
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.
I have tried to do google, but none of solution worked for me
回答1:
You can set the request mode to 'no-cors' like so:
fetch(url, {
mode: "no-cors",
...
})
