1、常用的默认配置的是:baseURL、method、timeout
① baseURL:设置url的基本结构(请求根地址),域名和协议,再结合属性url某个请求路径,axios会自动将baseURL 和 url 进行拼接,从而得出正确的请求路径。
② method:请求方式 get/post
③ timeout:延时时间(超过多少时间就取消请求)【单位是毫秒】
2、axios配置多个服务器url
javascript
// 请求时的基础配置VITE_APP_BASE_URL
export const URLMap = {
base: import.meta.env.MODE === 'development'
? import.meta.env.VITE_APP_BASE_URL
: (window as any).config.VITE_APP_BASE_URL,
pdf:import.meta.env.MODE === 'development'
? import.meta.env.VITE_APP_BASE_URL_PDF
: (window as any).config.VITE_APP_BASE_URL_PDF,
}
const REQUESTS : Record<string, AxiosInstance> = {}
declare module 'axios' {
interface AxiosResponse<T = any> {
errorinfo: null
doc: any
time: any
x: any
y: any
}
export function create(config?: AxiosRequestConfig): AxiosInstance
}
Object.keys(URLMap).forEach((item) => {
const REQUEST: AxiosInstance = axios.create({
baseURL: URLMap[item],
headers: {
'Content-Type': 'application/json;charset=UTF-8',
},
timeout: 300000,
withCredentials: item === 'data',
})
REQUESTS[item] = REQUEST
})
// 请求拦截器
Object.keys(REQUESTS).forEach((item) => {
REQUESTS[item].interceptors.request.use(async (config: AxiosRequestConfig) => {
const headerToken = await getToken()
config.headers = config.headers || {}
if (headerToken)
config.headers.Authorization = headerToken
if (config.headers.type === 'form') {
delete config.headers.type
config.data = qs.stringify(config.data)
config.headers['Content-Type'] = 'application/x-www-form-urlencoded'
}
return config
})
})
// 响应拦截器
Object.keys(REQUESTS).forEach((item) => {
REQUESTS[item].interceptors.response.use(
async (response: AxiosResponse) => {
const { status, data = {}, statusText } = response
const errorText = serverCodeMessage[status] || statusText
const error = ''
if (status)
return Promise.resolve(data)
message.error(error)
return Promise.reject(error)
},
(error) => {
message.error(String(new Error(error)))
return Promise.reject(new Error(error))
},
)
})
export default REQUESTS
3、配置api文件
javascript
import requests from '@/service/index'
export const getAll = (data: paramsInter) => requests.base({
url: 'xx/xx',
method: 'POST',
data,
})
export const get = (data: paramsInter) => requests.pdf({
url: 'xx/xx',
method: 'POST',
data,
})
这样,不同的接口实现从不同的服务器获取资源
4、文件中使用
javascript
import { getAll} from '@/service/xx/index'
onMounted(() => {
getXX()
})
function getXX() {
getAll(params).then((res) => {
// xxx
}
