I just realized that fetch does not send Accept-Language header by default, therefore I plan to add that. However, I haven't come across any way to get the string that the browser should generate.
For example, in my browser, all normal requests have a nice Accept-Language value:
en-US,en;q=0.9,ja;q=0.8,vi;q=0.7,la;q=0.6
My problem can be solved by either option:
- Is there a declaration that tell browser to include Accept-Language
header with
fetch? - Is there a way to get that string instead of generate it from
navigator.languages? Currently I am using this method, but I made it myself, and not sure if it's overkill/bad. I would prefer to use a built in way if possible.
var getAcceptLanguageValue = () => {
// Assume there are less than 10 languages
let q = 1;
return navigator.languages
.slice(0, 10)
.map(l => `${l};q=0.${10-q++}`)
.join(",");
};
The result I get is not identical obviously:
en-US;q=0.9,en;q=0.8,ja;q=0.7,vi;q=0.6,la;q=0.5
