Axios:如何正确取消请求拦截器中的请求? [英] Axios: how to cancel request inside request interceptor properly?

问题描述

如果没有令牌，我想取消请求，所以我这样做:

I want to cancel the request if there's no token so I do like this:

instance.interceptors.request.use(config => {
  if (!getToken()) {
    console.log("interceptors: no access token");
  } else {
    config.headers.Authorization = "Bearer " + getToken().accessToken;
    return config;
  }
});

但是在负面情况下，会出现错误TypeError: Cannot read property 'cancelToken' of undefined.

But in negative scenario there's an error TypeError: Cannot read property 'cancelToken' of undefined.

推荐答案

您不能在拦截器中使用令牌，而是抛出Cancel

You cannot use the token inside the interceptors but instead throw Cancel

axios.interceptors.response.use(function (response) {
  throw new axios.Cancel('Operation canceled by the user.');
}, function (error) {
  return Promise.reject(error);
});
