如何在 axios 中设置标题和选项? [英] How to set header and options in axios?

问题描述

我使用 Axios 执行这样的 HTTP 帖子:

I use Axios to perform an HTTP post like this:

import axios from 'axios'
params = {'HTTP_CONTENT_LANGUAGE': self.language}
headers = {'header1': value}
axios.post(url, params, headers)

这是正确的吗?或者我应该这样做:

Is this correct? Or should I do:

axios.post(url, params: params, headers: headers)

推荐答案

有几种方法可以做到这一点:

There are several ways to do this:

• 对于单个请求:

• For a single request:

let config = {
  headers: {
    header1: value,
  }
}

let data = {
  'HTTP_CONTENT_LANGUAGE': self.language
}

axios.post(URL, data, config).then(...)

用于设置默认全局配置:

For setting default global config:

axios.defaults.headers.post['header1'] = 'value' // for POST requests
axios.defaults.headers.common['header1'] = 'value' // for all requests

用于在 axios 实例上设置为默认值:

For setting as default on axios instance:

let instance = axios.create({
  headers: {
    post: {        // can be common or any other method
      header1: 'value1'
    }
  }
})

//- or after instance has been created
instance.defaults.headers.post['header1'] = 'value'

//- or before a request is made
// using Interceptors
instance.interceptors.request.use(config => {
  config.headers.post['header1'] = 'value';
  return config;
});
