axios ts 封装 比较简洁的封装 大部分场景够使用

import axios { AxiosResponse ,AxiosRequestConfig} from 'axios'

const serviceAxios = axios.create({
    baseURL: 'http://jsonplaceholder.typicode.com', //这里我简写了  全局配置即可
    timeout: 5000,
})
//请求拦截器
serviceAxios.interceptors.request.use(
    //根据业务需求在请求时候做一些配置
    // (response: AxiosRequestConfig) => {
    //     // response.headers['Access-Control-Allow-Origin'] = '*'
    //     response.headers?.['Content-Type'] = 'application/json'        return response;
    // }
)

serviceAxios.interceptors.response.use(
    (response: AxiosResponse) => {
        // response.headers['Access-Control-Allow-Origin'] = '*'
        console.log(response);
        if (response.status == 200) {
            return response.data
        } else {
            return requestHandler
        }

    }
)

// interface axiosParams<T> extends AxiosResponse {
//     data: T
// }
interface customDataParams<T> { //根据后端返回的估固定🧷格式
    data: T,
    message: string,
    status: boolean
}

// type returnResponseType<T> = axiosParams<customDataParams<T>>
type methodType = 'get' | 'post' | 'put' | 'delete'


type paramsData<T> = {
    params?: T,
    data?: T
}
const RequestAxiosInstance = <T, P>(url: string, method: methodType, params: paramsData<P> | {}, config?: AxiosRequestConfig) => {
    const data = serviceAxios<any, customDataParams<T>>({
        url,
        method,
        ...params,
        ...config,
    })
    return data
}

enum methodTypeMode {
    get = 'get',
    post = 'post',
    put = 'put',
    delete = 'delete',
}

const requestHandler = <T, P>(url: string, method: methodType, paramsData?: P, config?: AxiosRequestConfig) => {
    if (method === methodTypeMode.get || method === methodTypeMode.delete) {
        return RequestAxiosInstance<T, P>(url, method, { params: { ...paramsData } }, config)
    } else {
        return RequestAxiosInstance<T, P>(url, method, { data: paramsData }, config)
    }
    // return data;
}

/** 用法
  type returnData={
    name:string,
    age:18
}
type responseParams={
    username:string,
    password:string
}

const resultData=requestHandler<returnData,responseParams>("/user/login", "post", { username: "admin",password:"123456" })
