ES6`fetch是未定义的 [英] ES6 `fetch is undefined`
问题描述
在脚本文件中,我需要对服务器上的服务进行ajax调用。因为这样做:
fetch('url')。then(
response => response.json()
).then(
supervisoryItems => doSomething(supervisoryItems)
)
在Google Chrome中,这个功能很好,但在Firefox或IE上无效(我收到错误 fetch is undefined
) 。
在Google上搜索我发现这应该解决它:
'es6-promise'的导入承诺
promise.polyfill()
遗憾的是,它没有改变任何东西,我有同样的问题。任何帮助?
您需要将'isomorphic-fetch'模块添加到'package.json',然后导入。
npm install --save isomorphic-fetch es6-promise
然后在你的代码中
importisomorphic-fetch
请参阅 https://www.npmjs.com/package/isomorphic-fetch
I'm building a site with ES6 and Babel.
In a script file, I need to make an ajax call to a service on server. For that I'm doing like this:
fetch('url').then(
response => response.json()
).then(
supervisoryItems => doSomething(supervisoryItems)
)
In Google Chrome this works just fine, but it does not work on Firefox or IE (I'm getting the error fetch is undefined
).
Searching on Google I found this should fix it:
import promise from 'es6-promise'
promise.polyfill()
Sadly it does not change anything, I have the same issue. Any help?
You need to add the 'isomorphic-fetch' module to your 'package.json' and then import this.
npm install --save isomorphic-fetch es6-promise
Then in your code
import "isomorphic-fetch"
See https://www.npmjs.com/package/isomorphic-fetch
