axios动态设置默认标题

本文介绍了axios动态设置默认标题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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.headersmon = { 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.headersmon = { 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.headersmon['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.
