数据转换

默认的transformResponse直接返回小程序原始的返回数据{statusCode,...}

同时提供了根据状态码返回对应数据的转换方式

import {
    Request, transformRequestResponseOkData,
    Download, transformDownloadResponseOkData,
    Upload, transformUploadResponseOkData,
} from 'miniprogram-network';
 
// Request的默认响应拦设为成transformRequestResponseOkData,
// 正常2xx返回data部分，否则rejected
Request.Defaults.transformResponse = transformRequestResponseOkData;
// Download的默认响应拦设为transformDownloadResponseOkData，
// 正常2xx返回string,否则rejected
Download.Defaults.transformResponse = transformDownloadResponseOkData;
// Upload默认响应拦截transformUploadResponseOkData,
//正常2xx返回data,否则rejected
Upload.Defaults.transformResponse = transformUploadResponseOkData;
 
Download.download('url')
    .then(path=>{
        console.log(path);//string
    }).catch(res=>{
        console.error(res);//objct
    });

快速配置 setConfig

import { setConfig } from 'miniprogram-network';
 
//将Request,Upload,Download的默认baseURL设置为'https://api.newfuture.cc'
setConfig('baseURL', 'https://api.newfuture.cc');
 
//等效方式
setConfig({
    baseURL:'https://api.newfuture.cc'
})
 

Cache 缓存

import {getCache,downloadCache,CacheConfig} from 'miniprogram-network';
 
//getCache 与 Request共用配置
getCache('xxx').then(resolve);
getCache('xxx').then(resolve);
 
// downloadCache 与 Download共用配置
downloadCache('xxx').then();
 
CacheConfig.expire = 30*60*1000;//设置缓存时间
