Taro项目之请求API.HttpClient.ts封装

经过上次对运行命令的改装，我们便可轻松的获取到不同环境以使用不用的请求地址。
大致封装代码如下：

import Taro from "@tarojs/taro";
import { request, RequestParams } from "@tarojs/taro";
import { get, eq, merge, includes, delay, curryRight } from "lodash";
import { LOGIN_KEYS } from "../const/index";
import { PopupService, GlobalService } from "../service/";

export interface IResponseData<T = any> {
  code: string;
  msg: string;
  data: T;
}

class HttpRequest {
  static BASE_URL = {
    dev: "http://dev.***.com",
    test: "https://test.***.com",
    prd: "https://www.***.com"
  }[process.env.BUILD_ENV];

  static baseOptions = {
    header: {
      "content-type": "application/json",
      Authorization: `${Taro.getStorageSync(
        LOGIN_KEYS.USER_TOKEN_TYPE
      )} ${Taro.getStorageSync(LOGIN_KEYS.USER_TOKEN)}`
    },
    dataType: "json"
  };

  static generateFullUrl = (url: string) =>
    `${HttpRequest.BASE_URL}${url.startsWith("/") ? "" : "/"}${url}`;

  static requestSuccessHandler = (res, isCheckResponse, rs, rj) => {
    if (!isCheckResponse) {
      rs(res);

      return;
    }

    const statusCode = get(res, "statusCode");
    if (!eq(statusCode, 200)) {
      const error = get(res, "data.error");

      if (includes(["unauthorized", "invalid_token"], error)) {
        rj(res);

        PopupService.$showToast({
          title: "授权已失效，请重新授权登录",
          icon: "error",
          duration: 2000
        });

        delay(() => {
          try {
            GlobalService.$loginOut();
          } catch (er) {
            console.error(er);
          }
        }, 2000);

      return;
    } else {

    }
  };

  static requestFailHandler = (error, rj) => {
    PopupService.$message({
      message: JSON.stringify(get(error, "errMsg", "Unknow Error")),
      type: "error"
    });
    rj(error);
  };

  static request(url, method, data = {}, options = {}, isCheckResponse = true) {

      ) as Promise<IResponseData>;
    }
