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){
     ....
     ....
   }
 }

axios。Post ('url'， {"body":data}， { 标题:{ “内容类型”:“application / json” ｝ ｝ ）

你可以传递一个配置对象给axios，比如:

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

@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。

可以在axios请求中同时使用参数和body。

  sendAllData (data) {
        axios
        .post(API_URL + "receiveData", JSON.stringify(data), {
          headers: { "Content-Type": "application/json; charset=UTF-8" },
          params: { mail: xyx@example.col }, //Add mail as a param
        })
        .then((response) => console.log("repsonse", response.status)); 
  }

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; });
