真机调试ios 10.1.x的版本不支持fetch 所以一直loading显示白屏。
其他设备都没问题。 所以用主要属性window.fetch用来判断是否支持fetch 属性
import { baseUrl } from ‘./env‘ export default async(url = ‘‘, data = {}, type = ‘GET‘, method = ‘fetch‘) => { type = type.toUpperCase(); url = baseUrl + url; if (type == ‘GET‘) { let dataStr = ‘‘; //数据拼接字符串 Object.keys(data).forEach(key => { dataStr += key + ‘=‘ + data[key] + ‘&‘; }) if (dataStr !== ‘‘) { dataStr = dataStr.substr(0, dataStr.lastIndexOf(‘&‘)); url = url + ‘?‘ + dataStr; } } if (window.fetch && method == ‘fetch‘) { let requestConfig = { credentials: ‘include‘, method: type, headers: { ‘Accept‘: ‘application/json‘, ‘Content-Type‘: ‘application/json‘, ‘Authorization‘: localStorage.getItem(‘token‘), }, mode: "cors", // cache: "force-cache" } if (type == ‘POST‘) { Object.defineProperty(requestConfig, ‘body‘, { value: JSON.stringify(data) }) } try { const response = await fetch(url, requestConfig); const responseJson = await response.json(); return responseJson } catch (error) { throw new Error(error) } } else { return new Promise((resolve, reject) => { let requestObj; if (window.XMLHttpRequest) { requestObj = new XMLHttpRequest(); } else { requestObj = new ActiveXObject; } let sendData = ‘‘; if (type == ‘POST‘) { sendData = JSON.stringify(data); } requestObj.open(type, url, true); requestObj.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); requestObj.setRequestHeader("Accept","application/json"); requestObj.setRequestHeader("Content-Type","application/json"); requestObj.setRequestHeader("Authorization",localStorage.getItem(‘token‘)); requestObj.send(sendData); requestObj.onreadystatechange = () => { if (requestObj.readyState == 4) { if (requestObj.status == 200) { let obj = requestObj.response if (typeof obj !== ‘object‘) { obj = JSON.parse(obj); } resolve(obj) } else { reject(requestObj) } } } }) } }
