axios动态设置默认标题 [英] axios set default headers dynamically

问题描述

我想设置一个随每个请求发送的标头:

I want to set a header that sent with each request:

axios.defaults.headers.common = {
    Accept: 'application/json',
    'X-CSRF-TOKEN': store.state.csrf
};

这仅在页面加载时评估.我希望它是动态的，因为csrf值以后可能会更改.像这样:

This is only evaluated at the page load. I would like it to be dynamic since the csrf value may change later on. Something like:

axios.defaults.headers.common = {
    Accept: 'application/json',
    'X-CSRF-TOKEN': () => store.state.csrf
};

但是，这不起作用.

推荐答案

您可以随时覆盖/扩展默认值:

You can overwrite/extend the defaults at any time:

// set defaults...

// do requests...

// overwrite CSRF token
axios.defaults.headers.common['X-CSRF-TOKEN'] = store.state.csrf;

// do more requests...

或者您可以仅针对特定实例更改默认值.
