axiosのパラメータ指定方法まとめ

More than 1 year has passed since last update.

概要

HTTPクライアントのaxiosを使っていて、
パラメータの指定する方法を毎回調べるのが面倒だったのでまとめました。
ほぼREADMEに書いてある内容と同じです。

GET

クエリパラメータをつける

直接URLにつける

axios.get('/user?ID=12345');

optionに指定する

axios.get('/user', {
  params: {
    // ここにクエリパラメータを指定する
    ID: 12345
  }
});

POST

json形式で送る

axios.post('/user', {
    firstName: 'Fred',
    lastName: 'Flintstone'
});

application/x-www-form-urlencoded形式で送る

URLSearchParams を使う方法

var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);

qs を使う方法

var qs = require('qs');
axios.post('/foo', qs.stringify({ 'bar': 123 }));
