【问题描述】：

有人可以帮我写一些代码吗，我正在尝试使用离子原生 HTTP，但它不工作。访问来自http.post 的响应时，我不断收到错误消息。我得到的错误是：

“HTTPResponse”类型上不存在属性“json”

或

“Promise”类型上不存在“订阅”属性。

当我使用import { Http } from '@angular/HTTP' 时，一切正常，但由于某些原因，有时在设备上@987654323@ 不起作用，这就是我想使用import { HTTP } from '@ionic-native/http'; 的原因下面我已经包含了这两个代码，请有人帮助我。

这很好用：

import { Injectable} from '@angular/core';
import {Http} from '@angular/http';
import 'rxjs/add/operator/map';

import {Auth0Config as Config} from '../config/auth0';

@Injectable()
 export class Auth {
 URL: String;

   constructor(public http: Http) {
     this.url = Config.AUTH0_DOMAIN;
   }

   login(user: String, pass: String) {
    let endpoint = "/oauth/token";
    let body = {
        "client_id": Config.AUTH0_CLIENTID,
        "username": user,
        "password": pass,
        "connection": Config.AUTH0_CONNECTION,
        "grant_type": "password"
    };
    return this.http.post(this.url + endpoint, body).map(res => res.json());
  }

  getProfile(token: String) {
    let endpoint = "/userinfo";
    let query = "?access_token=" + token;
    return this.http.get(this.url + endpoint + query).map(res => res.json());
  }

}

没用

import {Injectable} from '@angular/core';
import {HTTP} from '@ionic-native/http';
import 'rxjs/add/operator/map';

import {Auth0Config as Config} from '../config/auth0';

@Injectable()
export class Auth {
URL: String;

  constructor(public http: HTTP) {
    this.url = Config.AUTH0_DOMAIN;
  }

  login(user: String, pass: String) {
    let endpoint = "/oauth/token";
    let body = {
        "client_id": Config.AUTH0_CLIENTID,
        "username": user,
        "password": pass,
        "connection": Config.AUTH0_CONNECTION,
        "grant_type": "password"
    };
    return this.http.post(this.url + endpoint, body, {}).then(res => {
        var res = res.json()
    });
  }

  getProfile(token: String) {
    let endpoint = "/userinfo";
    let query = "?access_token=" + token;
    return this.http.get(this.url + endpoint + query, {}, {}) //.map(res => res.json());
  }

}

【解决方案1】：

问题来了：

  var res = res.json()

角度http返回Promise<Response>

而原生返回Promise<HTTPResponse>

用这一行代替

 var res = res
