axios入门之响应类型

axios请求配置可以设置响应类型

export type ResponseType =
  | 'arraybuffer'
  | 'blob'
  | 'document'
  | 'json'
  | 'text'
  | 'stream';

默认的响应类型和content-type有关，text/plain 类型解析为 string

const server = http.createServer((req, res) => {
    res.setHeader('content-type','text/plain')
    res.write('hello world')
    res.end()
})

axios.get('http://localhost:3000').then(res => {
    console.log(typeof res.data)
})

const server = http.createServer((req, res) => {

    res.end()
})

axios.get(
