[英]Axios: getting two requests OPTIONS & POST
I'm trying to post data.我正在尝试发布数据。 Everything works fine, but I don't know why I'm getting two requests
OPTIONS
& POST
一切正常,但我不知道为什么我收到两个请求
OPTIONS
& POST
Here's the code:这是代码:
const url = 'http://rest.learncode.academy/api/johnbob/myusers';
export function postUsers(username, password) {
let users = {
username,
password,
};
return{
type: "USERS_POST",
payload: axios({
method:'post',
url:url,
data: users,
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
})
}
}
Non-simple CORS requests via AJAX are pre-flighted.通过 AJAX 的非简单 CORS 请求是预检的。 Read more about it here .
在此处阅读更多相关信息。 This is a browser behavior and nothing specific to axios.
这是浏览器行为,与 axios 无关。 There's nothing inherently wrong with this behavior and if it's working for you, you can just leave it.
这种行为本身没有任何问题,如果它对你有用,你可以放弃它。
If you insist on getting rid of it, there are a few ways you can go about:如果你坚持要摆脱它,有几种方法可以解决:
You can set Access-Control-Allow-Origin: *
on your server to disable CORS.您可以在服务器上设置
Access-Control-Allow-Origin: *
以禁用 CORS。
Make your CORS request a simple one.使您的 CORS 请求变得简单。 You will have to change the
Content-Type
header to application/x-www-form-urlencoded
or multipart/form-data
or text/plain
.您必须将
Content-Type
标头更改为application/x-www-form-urlencoded
或multipart/form-data
或text/plain
。 No application/json
.没有
application/json
。
I'd say just leave it as it is if the OPTIONS
request is not blocking you.如果
OPTIONS
请求没有阻止您,我会说就保持原样。
