有几种方法可以做到:

For a single request: let config = { headers: { header1: value, } } let data = { 'HTTP_CONTENT_LANGUAGE': self.language } axios.post(URL, data, config).then(...) For setting default global config: axios.defaults.headers.post['header1'] = 'value' // for POST requests axios.defaults.headers.common['header1'] = 'value' // for all requests 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; });

你可以初始化一个默认头axios.defaults.headers

 axios.defaults.headers = {
        'Content-Type': 'application/json',
        Authorization: 'myspecialpassword'
    }

   axios.post('https://myapi.com', { data: "hello world" })
        .then(response => {
            console.log('Response', response.data)
        })
        .catch(e => {
            console.log('Error: ', e.response.data)
        })

这是一个简单的配置头和responseType的例子:

var config = {
  headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
  responseType: 'blob'
};

axios.post('http://YOUR_URL', this.data, config)
  .then((response) => {
  console.log(response.data);
});

Content-Type可以是'application/x-www-form-urlencoded'或'application/json' 也可以是'application/json;charset=utf-8'

responseType可以是arraybuffer, blob, document, json, text, stream

在这个例子中，这个。数据就是你想要发送的数据。它可以是一个值或数组。(如果你想发送一个对象，你可能需要序列化它)

你可以用Headers发送一个get请求(例如使用jwt进行身份验证):

axios.get('https://example.com/getSomething', {
 headers: {
   Authorization: 'Bearer ' + token //the token is a variable which holds the token
 }
})

你也可以发送一个post请求。

axios.post('https://example.com/postSomething', {
 email: varEmail, //varEmail is a variable which holds the email
 password: varPassword
},
{
  headers: {
    Authorization: 'Bearer ' + varToken
  }
})

我的做法是这样设置一个请求:

 axios({
  method: 'post', //you can set what request you want to be
  url: 'https://example.com/request',
  data: {id: varID},
  headers: {
    Authorization: 'Bearer ' + varToken
  }
})

使用异步/等待

Axios post签名 Post (url:字符串，数据?: any, config?: AxiosRequestConfig): Promise<AxiosResponse> data和config都是可选的 AxiosRequestConfig可以查看- https://github.com/axios/axios/blob/e462973a4b23e9541efe3e64ca120ae9111a6ad8/index.d.ts#L60

 ....
 ....
 try {
   ....
   ....
   const url = "your post url"
   const data = {
     HTTP_CONTENT_LANGUAGE: self.language
   }
   const config = {
      headers: {
       "header1": value
      },
      timeout: 1000,
      // plenty more options can be added, refer source link above
    }

   const response = await axios.post(url, data, config);
   // If Everything's OK, make use of the response data
   const responseData = response.data;
   ....
   ....
 }catch(err){
   // handle the error
   if(axios.isAxiosError(err){
     ....
     ....
   }
 }

@user2950593 您的axios请求是正确的。您需要在服务器端允许您的自定义头。 如果你在php中有api，那么这段代码将为你工作。

header("Access-Control-Allow-Origin: *");   
header("Access-Control-Allow-Methods: GET, POST, OPTIONS, HEAD");
header("Access-Control-Allow-Headers: Content-Type, header1");

一旦您允许在服务器端使用自定义头文件，axios请求就可以正常工作了。
