Javascript 如何在 axios 中设置标题和选项？

How to set header and options in axios?

提问by user2950593

I use Axios to perform an HTTP post like this:

我使用 Axios 执行这样的 HTTP 帖子：

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

Is this correct? Or should I do:

这样对吗？或者我应该这样做：

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

There are several ways to do this:

做这件事有很多种方法：

• 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;
  });
  

• 对于单个请求：

  let config = {
    headers: {
      header1: value,
    }
  }
  
  let data = {
    'HTTP_CONTENT_LANGUAGE': self.language
  }
  
  axios.post(URL, data, config).then(...)
  

• 设置默认全局配置：

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

• 要在 axios 实例上设置为默认值：

  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;
  });

You can send a get request with Headers (for authentication with jwt for example):

您可以发送带有 Headers 的 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
 }
})

Also you can send a post request.

您也可以发送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
  }
})

My way of doing it,is to set a request like this:

我的做法是设置这样的请求：

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

You can pass a config object to axios like:

您可以将配置对象传递给 axios，例如：

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

This is a simple example of a configuration with headers and responseType:

这是带有标头和响应类型的配置的简单示例：

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 can be 'application/x-www-form-urlencoded' or 'application/json' and it may work also 'application/json;charset=utf-8'

内容类型可以是 'application/x-www-form-urlencoded' 或 'application/json' 也可以是 'application/json;charset=utf-8'

responseType can be 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream'

responseType 可以是“arraybuffer”、“blob”、“document”、“json”、“text”、“stream”

In this example, this.data is the data you want to send. It can be a value or an Array. (If you want to send an object you'll probably have to serialize it)

在本例中，this.data 是您要发送的数据。它可以是一个值或一个数组。（如果你想发送一个对象，你可能需要序列化它）

You can initialize a default header axios.defaults.headers

您可以初始化默认标头 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)
        })

if you want to do a get request with params and headers.

如果您想使用参数和标头执行 get 请求。

var params = {
  paramName1: paramValue1,
  paramName2: paramValue2
}

var headers = {
  headerName1: headerValue1,
  headerName2: headerValue2
}

 Axios.get(url, {params, headers} ).then(res =>{
  console.log(res.data.representation);
});

回答by Prateek Arora

Here is the Right way:-

这是正确的方法：-

axios.post('url', {"body":data}, {
    headers: {
    'Content-Type': 'application/json'
    }
  }
)

试试这个代码

in example code use axios get rest API.

在示例代码中使用 axios get rest API。

in mounted

在安装

  mounted(){
    var config = {
    headers: { 
      'x-rapidapi-host': 'covid-19--statistics.p.rapidapi.com',
      'x-rapidapi-key': '5156f83861mshd5c5731412d4c5fp18132ejsn8ae65e661a54' 
      }
   };
   axios.get('https://covid-19--statistics.p.rapidapi.com/v1/stats? 
    country=Thailand',  config)
    .then((response) => {
    console.log(response.data);
  });
}

I have face this issue in post request. I have changed like this in axios header. It works fine.

我在 post request 中遇到过这个问题。我在 axios 头文件中做了这样的改变。它工作正常。

axios.post('http://localhost/M-Experience/resources/GETrends.php',
      {
        firstName: this.name
      },
      {
        headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
      });
