我正在使用本机脚本的Angular版本,并尝试创建网络登录系统。
下面是我尝试登录网络的代码。
home.component.ts
import { LoginService } from '../Services/login/login.service';
export class LoginComponent implements OnInit {
public user: User;
loginForm: FormGroup;
constructor(private router: Router,
private userService: UserService,
private page: Page,
public loginDetails: LoginDetails,
private LoginService: LoginService
) {
this.user = new User();
this.user.email = "m@m.com";
this.user.password = "pass123";
this.user.logo = "~/Images/opos_logo.png";
}
submit() {
/* set a user variable with data from the formGroup */
const user: string = this.user.email;
/* set a password variable with data from the formGroup */
const password: string = this.user.password;
this.LoginService.loginUser(user, password)
.subscribe(data => this.checkUser(data));
}
}
Services / login / login.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Component, OnInit } from "@angular/core";
import { Jwt } from '../../Classes/jwt';
@Injectable({
providedIn: 'root'
})
export class LoginService {
loginUrl = 'http://localhost/Login.w';
constructor(private _http: HttpClient) { }
loginUser(user, pass) {
return this._http.get<Jwt>(
this.loginUrl, { params: { fi_user: user, fi_pass: pass } });
}
}
当我尝试这样运行我的应用程序时,会出现以下错误:
“ originalStack”:“错误:java.io.IOException:在新的ZoneAwareError上,不允许对本地主机的明文HTTP通信\ n(file:///data/data/org.nativescript.preview/files/app/tns_modules/ @ nativescript / angular / zone-js / dist / zone-nativescript.js:1298:31)\ n在onRequestComplete(file:///data/data/org.nativescript.preview/files/app/tns_modules/@nativescript/ core / http / http-request / http-request.js:54:30)\ n位于Object.onComplete(file:///data/data/org.nativescript.preview/files/app/tns_modules/@nativescript/core /http/http-request/http-request.js:43:7)“
要尝试按照帖子Android 8: Cleartext HTTP traffic not permitted上的建议并遵循该帖子上的建议来解决此问题。 我在路径/App_Resources/Android/AndroidManifest.xml上的程序中添加了一个androidmanifest.xml文件(这还不是应用程序的一部分,因此我不确定应用程序是否正在访问该文件)。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="__PACKAGE__"
android:versionCode="1"
android:versionName="1.0">
<supports-screens
android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"/>
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="__APILEVEL__"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:name="com.tns.NativeScriptApplication"
android:allowBackup="true"
android:icon="@drawable/icon"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:networkSecurityConfig="@xml/network_security_config">
<activity
android:name="com.tns.NativeScriptActivity"
android:label="@string/title_activity_kimera"
android:configChanges="keyboardHidden|orientation|screenSize"
android:theme="@style/LaunchScreenTheme">
<meta-data android:name="SET_THEME_ON_LAUNCH" android:resource="@style/AppTheme" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.tns.ErrorReportActivity"/>
</application>
我还向堆栈res / xml / network_security_config.xml路径中添加了堆栈溢出帖子建议的network_security_config.xml文件
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">domain.com (to be adjusted)</domain>
</domain-config>
</network-security-config>
我还尝试将应用程序android:usesCleartextTraffic =“ true”标记添加到我的home.component.html中,以修复错误,但这不能解决问题。
答案 0 :(得分:2)
尝试:
loginUrl = 'http://10.0.2.2/Login.w';
我刚刚阅读了以下文章:https://stackoverflow.com/a/48591525 @EdwardGarson写道:
在仿真器中,localhost或127.0.0.1指的是仿真器本身,而不是本地计算机。您需要使用桥接到本地计算机的ip 10.0.2.2。
