Ionic 4 WordPress REST用户验证Stuc

Question

我正在尝试通过WP REST Api上开发人员的引导框架进行身份验证。附件是移动应用程序登录页面上的代码，每当我尝试登录时，它将停留在“正在加载，请稍候”。任何想法？提前致谢。单击登录按钮时显示doLogin（）函数。 login.ts

doLogin() {
    this.translateService.get(['Notice', 'Loading', 'NetWork_Error', 'OK', 'Sign_In_Failed', 'Sign_In_No_Email', 'Sign_In_Email_Error', 'No_Email_Or_Password']).
    subscribe(async value => {
      var loadingModal = await this.loadingCtrl.create({
        message: value['Loading']
      });
      if (this.appConfig.Enable_Login_With_Password) {
        if (this.email == null || this.password == null || this.email.trim().length == 0 || this.password.trim().length < 6) {
          var alert=await this.alertCtrl.create({
            header: value['Notice'],
            message: value['No_Email_Or_Password'],
            buttons: [value['OK']]
          });
          alert.present();
          return;
        }

        loadingModal.present();

        var password = this.password;
        if (this.appConfig.App_Secret != '') {
          var key = CryptoJS.enc.Utf8.parse(CryptoJS.MD5(this.appConfig.App_Secret).toString());
          var iv = CryptoJS.enc.Utf8.parse(CryptoJS.MD5(this.appConfig.App_Secret).toString().substr(0, 16));
          password = CryptoJS.AES.encrypt(password, key, { iv: iv }).toString();
        }

        this.sowService.login({ email: this.email, password: encodeURIComponent(password) }).then(async (data: any) => {
          if (data && data != 'error') {

            await this.storage.set('oddwolves-user-info', data);
            loadingModal.dismiss();
            this.modalCtrl.dismiss();

          } else {
            loadingModal.dismiss();
            var alert=await this.alertCtrl.create({

                 message: value['Sign_In_Failed'],
                 buttons: [value['OK']]
