[英]CORS error: Request header field authentication is not allowed by Access-Control-Allow-Headers in preflight response
注销时,会发生此错误。 Access to XMLHttpRequest at ' http://127.0.0.1:8000/api/auth/logout/ ' from origin ' http://localhost:3000 ' has been blocked by CORS policy: Request header field authentication is not allowed by Access-预检响应中的 Control-Allow-Headers。
我将 auth.js 的注销 function 称为 onClick。 我不知道为什么刷新页面时会注销。
减速器.js
case LOGOUT_SUCCESS:
localStorage.removeItem("token");
return {
...state,
isAuthenticated: null,
isLoading: false,
user: null,
isFreelancer: false
};
注销 action/auth.js 的 function
export const logout = () => (dispatch, getState) => {
const token = getState().auth.token;
const config = {
headers: {
"Content-Type": "application/json"
}
};
if (token) {
config.headers["Authentication"] = `Token ${token}`;
}
axios
.post("http://127.0.0.1:8000/api/auth/logout/", null, config)
.then(res => {
dispatch({ type: LOGOUT_SUCCESS });
})
.catch(err => {
console.log(err.message);
});
};
我希望立即注销,但每次刷新页面时都会注销。
如果您使用的是 Create-React-App,您可以在 package.json 文件中简单地执行此操作:
"proxy": "http://127.0.0.1:8000",
这将是代理请求,浏览器不会阻止响应。
