GooglePlus类没有Ionic应用程序中Cordova插件的登录功能

Question

我正在尝试关注this tutorial在Ionic应用中使用GooglePlus登录。我已经按Eddy Verbruggen安装了该插件，根据教程，我应该在home.ts的顶部添加此行。

import { GooglePlus } from 'ionic-native';

当我尝试构建时，Ionic抱怨了。改变它有助于

import { GooglePlus } from '@ionic-native/google-plus';

但是现在以下代码不会转换

GooglePlus.login({.....

因为“类型'类型'GooglePlus'上不存在”属性'登录'“。使用WebStorm我可以控制点击GooglePlus，它会转到node_modules/@ionic-native/google-plus中的类定义，它表明该类显然有一个名为login的函数。

• npm 5.5.1
• Ionic 3.19.0
• Cordova 7.1.0
• OS X 10.12.6

Answer 1

本教程中我需要的这些更改部分详见Ionic's docs

1）将GooglePlus添加到构造函数

      @ExceptionHandler({ ResourceNotFoundException.class })
      @ResponseStatus(value = HttpStatus.NOT_FOUND)
      public ResponseEntity<Object> handleResourceNotFound(ResourceNotFoundException ex, WebRequest request) {
             ErrorResponseProperty property = ErrorResponseProperty.builder()
                        .id("req_id")
                        .message("resource not found")
                        .status(Integer.toString(Response.SC_NOT_FOUND)).build();

          List<ErrorResponseProperty> propertyList = new ArrayList<ErrorResponseProperty>();
          propertyList.add(property);

          ErrorResponsePOJO responsePOJO = ErrorResponsePOJO.builder()
                        .errors(propertyList).build();

          return new ResponseEntity<Object>(responsePOJO, HttpStatus.NOT_FOUND);
      }

      @ExceptionHandler({ NoHandlerFoundException.class })
      @ResponseStatus(value = HttpStatus.NOT_FOUND)
      public ResponseEntity<Object> handleResourceUnavailable(NoHandlerFoundException ex, WebRequest request) {
             ErrorResponseProperty property = ErrorResponseProperty.builder()
                        .id("req_id")
                        .message("resource not found")
                        .status(Integer.toString(Response.SC_NOT_FOUND)).build();

          List<ErrorResponseProperty> propertyList = new ArrayList<ErrorResponseProperty>();
          propertyList.add(property);

          ErrorResponsePOJO responsePOJO = ErrorResponsePOJO.builder()
                        .errors(propertyList).build();

          return new ResponseEntity<Object>(responsePOJO, HttpStatus.NOT_FOUND);
      }

2）将constructor(private googlePlus: GooglePlus) { } 更改为GooglePlus.login()

3）导入GooglePlus并将其作为提供商添加到this.googlePlus.login

中

app.module.ts

...

import { GooglePlus } from '@ionic-native/google-plus';
