fetch-mock 不会模拟我的 fetch [英] fetch-mock does not mock my fetch
问题描述
这里是代码片段:
var fetch = require("node-fetch");
var fetchMock = require("fetch-mock");
function setupMockBlockChainExplorer() {
fetchMock.mock("https://cardanoexplorer.com/api/addresses/summary/DdzFFzCqrhsmagp4fDZpcY9UaBJk4Z8GaDfxqMCSwxPs3PnVoXmJWUZcgAxw3diCHVYauontEfk7YGeAu2LvAwq3aG2XQ8Mtsz7Vc8LA", {
"status" : 200,
"body" : "override"
});
}
async function makeRequest(url, method = "get", body = null, headers = null) {
const res = await fetch(url, {
method: method,
headers: headers,
body: body,
});
return res.json()
};
setupMockBlockChainExplorer();
var req = makeRequest("https://cardanoexplorer.com/api/addresses/summary/DdzFFzCqrhsmagp4fDZpcY9UaBJk4Z8GaDfxqMCSwxPs3PnVoXmJWUZcgAxw3diCHVYauontEfk7YGeAu2LvAwq3aG2XQ8Mtsz7Vc8LA");
// I would expect it to print "override" but it prints the http response from the real request instead
req.then(console.log)
所以我正在尝试覆盖 HTTP 请求,如您在上面的代码中所见,但我仍然使用 fetch 访问真实 URL.我已阅读 fetch-mock 文档 (http://www.wheresrhys.co.uk/fetch-mock/installation.html),我也尝试像这样设置配置:
So I'm trying to override a HTTP request as you can see in the code above, but I'm still hitting the real URL with fetch. I have read the fetch-mock docs (http://www.wheresrhys.co.uk/fetch-mock/installation.html) and I also tried setting the config like this:
fetchMock.config = Object.assign(fetchMock.config, {
"fetch": fetch
});
但没有运气.我做错了什么?
but with no luck. What am I doing wrong?
推荐答案
我认为问题在于您没有使用 fetch
的全局"版本.
I think the issue is that you are not using the 'global' version of fetch
.
尝试使用 isomorphic-fetch
而不是 node-fetch
.
Trying using isomorphic-fetch
instead of node-fetch
.
您可以在这里查看更多说明.
You can see more explanation here.
注意这句话:
使用 import 'isomorphic-fetch'
,而不是 import fetch from 'isomorphic-fetch'
Use import 'isomorphic-fetch'
, not import fetch from 'isomorphic-fetch'
