How to set header and options in axios?

问题

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)

Is this correct? Or should I do:

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

回答1:

There are several ways to do this:

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;
});

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

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.

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:

 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:

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:

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'

responseType can be '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)

回答5:

You can initialize a default header 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)
        })

回答6:

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

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

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

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

Here is the Right way:-

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