1.网络请求封装

import qs from "qs";
import { getLocalStorage } from "./storage";interface RequestOption {url: string,payload: object,method?: any,showToast?: boolean,contentType?: string,urlPrefix?: string,     // 请求前缀isPublic?: boolean,     // 是否公共请求方法
}const baiduServer = `https://fanyi-api.baidu.com/api/trans/vip/translate`;// content-type 类型
export const ENUM_CONTENT_TYPE = {FORM: "application/x-www-form-urlencoded", //url编码格式JSON: "application/json", //json格式
};export async function baiduRequest(options: RequestOption):Promise<any> {const {url,payload,method = "GET",showToast = true,contentType = "application/x-www-form-urlencoded",urlPrefix = "",isPublic = false,} = options;const token = await getLocalStorage("token");const requestUrl = `${urlPrefix}${baiduServer}${url}`;const header: any = token ? { token: token } : {};if (method === "POST") {header["content-type"] = contentType;}if (method === "DELETE") {header["content-type"] = contentType;}console.log(contentType, "请求头类型");//请求拦截器uni.addInterceptor("request", {invoke(args) {console.log("🚀 ~ invoke ~ args:", args);if (method === "GET" ||(method === "POST" &&contentType === "application/x-www-form-urlencoded")) {if (args?.data) {args.url =args.url + "?" + qs.stringify(args.data, { indices: false });args.data = undefined;}}},});return new Promise((resolve, reject) => {uni.request({url: requestUrl,method,data: payload,header,success: (res: any) => {resolve(res.data);},fail: (err: any) => {uni.showToast({title: "网络开小差了~请检查网络再重试",icon: "none",});reject(err);},});});
}

2.使用该请求

封装translate.ts方法，md5加密方法， from: "zh",to: "jp",为可选项，可传入对于参数参考文档翻译对应语言。即可引入使用

//@ts-nocheck
import { baiduRequest } from "@/utils/request";var MD5 = function (string) {function RotateLeft(lValue, iShiftBits) {return (lValue << iShiftBits) | (lValue >>> (32 - iShiftBits));}function AddUnsigned(lX, lY) {var lX4, lY4, lX8, lY8, lResult;lX8 = lX & 0x80000000;lY8 = lY & 0x80000000;lX4 = lX & 0x40000000;lY4 = lY & 0x40000000;lResult = (lX & 0x3fffffff) + (lY & 0x3fffffff);if (lX4 & lY4) {return lResult ^ 0x80000000 ^ lX8 ^ lY8;}if (lX4 | lY4) {if (lResult & 0x40000000) {return lResult ^ 0xc0000000 ^ lX8 ^ lY8;} else {return lResult ^ 0x40000000 ^ lX8 ^ lY8;}} else {return lResult ^ lX8 ^ lY8;}}function F(x, y, z) {return (x & y) | (~x & z);}function G(x, y, z) {return (x & z) | (y & ~z);}function H(x, y, z) {return x ^ y ^ z;}function I(x, y, z) {return y ^ (x | ~z);}function FF(a, b, c, d, x, s, ac) {a = AddUnsigned(a, AddUnsigned(AddUnsigned(F(b, c, d), x), ac));return AddUnsigned(RotateLeft(a, s), b);}function GG(a, b, c, d, x, s, ac) {a = AddUnsigned(a, AddUnsigned(AddUnsigned(G(b, c, d), x), ac));return AddUnsigned(RotateLeft(a, s), b);}function HH(a, b, c, d, x, s, ac) {a = AddUnsigned(a, AddUnsigned(AddUnsigned(H(b, c, d), x), ac));return AddUnsigned(RotateLeft(a, s), b);}function II(a, b, c, d, x, s, ac) {a = AddUnsigned(a, AddUnsigned(AddUnsigned(I(b, c, d), x), ac));return AddUnsigned(RotateLeft(a, s), b);}function ConvertToWordArray(string) {var lWordCount;var lMessageLength = string.length;var lNumberOfWords_temp1 = lMessageLength + 8;var lNumberOfWords_temp2 =(lNumberOfWords_temp1 - (lNumberOfWords_temp1 % 64)) / 64;var lNumberOfWords = (lNumberOfWords_temp2 + 1) * 16;var lWordArray = Array(lNumberOfWords - 1);var lBytePosition = 0;var lByteCount = 0;while (lByteCount < lMessageLength) {lWordCount = (lByteCount - (lByteCount % 4)) / 4;lBytePosition = (lByteCount % 4) * 8;lWordArray[lWordCount] =lWordArray[lWordCount] |(string.charCodeAt(lByteCount) << lBytePosition);lByteCount++;}lWordCount = (lByteCount - (lByteCount % 4)) / 4;lBytePosition = (lByteCount % 4) * 8;lWordArray[lWordCount] = lWordArray[lWordCount] | (0x80 << lBytePosition);lWordArray[lNumberOfWords - 2] = lMessageLength << 3;lWordArray[lNumberOfWords - 1] = lMessageLength >>> 29;return lWordArray;}function WordToHex(lValue) {var WordToHexValue = "",WordToHexValue_temp = "",lByte,lCount;for (lCount = 0;
