如何在Flutter中集成华为认证服务

最近发现华为AGC认证服务支持Flutter框架了，期待这个平台的支持已经很久了，所以迫不及待接入了，关联了自己的邮箱等账号。

集成步骤

1. 安装flutter环境

a) 下载Flutter sdk包，地址：https://flutter.dev/docs/get-...

将压缩包解压到任意文件夹，例如D:Flutter

b) 将flutter命令文件添加到环境变量中，此处我添加的Path为D:Flutterflutter_windows_1.22.2-stableflutterbin。

c) 在Android Studio中点击“File-Settings-Plugins”，下载Flutter和Dart插件，重启Android Studio使插件生效。

1. 开通服务&创建工程

a) 在AGC创建Android应用并开通认证服务

b) 开启认证服务中的匿名帐号，手机帐号，邮箱帐号

c) 在Android Studio中新建Flutter工程

d) 将agconnect-services.json文件放入Android/app目录下

e) 配置Maven仓地址和AGC插件地址。

a. 打开Flutter项目android文件夹下的build.gradle文件。

b. 在allprojects ->repositories里面配置maven仓地址。

c. 在buildscript->repositories中配置maven仓地址。

d. 在buildscript->dependencies中配置AppGallery Connect插件地址。

1. 添加编译依赖和AGC插件地址。

a. 打开Flutter项目android/app文件夹下的build.gradle文件。
b. 在文件中添加如下配置。

1. 集成SDK

在Flutter项目的pubspec.yaml文件中添加依赖：

dependencies:
flutter:
sdk: flutter
# Add the following line:
agconnect_auth: ^1.1.0

然后点击Pub get进行同步

1. 接入功能
2. 匿名帐号登录

匿名帐号只需要调用signInAnonymously接口进行登录

_signIn() async {
AGCAuth.instance.signInAnonymously().then((value) {
setState(() {
_log =
'signInAnonymously = ${value.user.uid} , ${value.user.providerId}';
});
});
}

通过value，我们可以获取到用户信息，例如这里我们获取到了user的id。

1. 手机号&邮箱认证

手机号邮箱账号认证首先需要发送验证码，

手机号请求验证码，即调用requestVerifyCode方法，传入手机号、国家码、设置项作为参数：

_requestPhoneVerifyCode(VerifyCodeAction action) {
String countryCode = _countryCodeController.text;
String phoneNumber = _phoneNumberController.text;
VerifyCodeSettings settings = VerifyCodeSettings(action, sendInterval: 30);
PhoneAuthProvider.requestVerifyCode(countryCode, phoneNumber, settings).then((value) => print(value.validityPeriod));
}

邮箱请求验证码，即调用requestVerifyCode方法，传入邮箱、设置项作为参数：

_requestEmailVerifyCode(VerifyCodeAction action) {
String email = _emailController.text;
VerifyCodeSettings settings = VerifyCodeSettings(action, sendInterval: 30);
EmailAuthProvider.requestVerifyCode(email, settings)
.then((value) => print(value.validityPeriod));
}

而后是创建用户的操作：

创建手机账号用户，需要调用createPhoneUser方法，传入封装好的PhoneUser对象

_createPhoneUser() async {
bool result = await _showPhoneDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String countryCode = _countryCodeController.text;
String phoneNumber = _phoneNumberController.text;
String verifyCode = _verifyCodeController.text;
String password = _passwordController.text;
AGCAuth.instance.createPhoneUser(PhoneUser(countryCode, phoneNumber, verifyCode, password: password)) .then((value) {
setState(() {
_log = 'createPhoneUser = ${value.user.uid} , ${value.user.providerId}';
});
}).catchError((error)=>print(error));
}

创建邮箱账号用户，需要调用createEmailUser方法，传入封装好的EmailUser对象。

_createEmailUser() async {
bool result = await _showEmailDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String email = _emailController.text;
String verifyCode = _verifyCodeController.text;
String password = _passwordController.text;
AGCAuth.instance
.createEmailUser(EmailUser(email, verifyCode, password: password))
.then((value) {
setState(() {
_log = 'createEmailUser = ${value.user.uid} , ${value.user.providerId}';
});
}).catchError((error) => print(error));
}

最后是登录功能，有两种登录模式，一种是密码登录方式：

• 手机账号，调用signIn方法，传入使用手机号等生成的认证凭据。

_signInWithPassword() async {
bool result = await _showPhoneDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String countryCode = _countryCodeController.text;
String phoneNumber = _phoneNumberController.text;
String password = _passwordController.text;
AGCAuthCredential credential = PhoneAuthProvider.credentialWithPassword(countryCode, phoneNumber, password);
AGCAuth.instance.signIn(credential).then((value) {
setState(() {
_log = 'signInWithPassword = ${value.user.uid} , ${value.user.providerId}';
});
});
}

• 邮箱账号：调用signIn方法，传入通过邮箱和密码生成的认证凭据。

_signInWithPassword() async {
bool result = await _showEmailDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String email = _emailController.text;
String password = _passwordController.text;
AGCAuthCredential credential =
EmailAuthProvider.credentialWithPassword(email, password);
AGCAuth.instance.signIn(credential).then((value) {
setState(() {
_log =
'signInWithPassword = ${value.user.uid} , ${value.user.providerId}';
});
});
}

另一种是验证码登录方式：

• 手机账号：调用signIn方法，传入通过手机、验证码和密码生成的认证凭据。

_signInWithVerifyCode() async {
bool result = await _showPhoneDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String countryCode = _countryCodeController.text;
String phoneNumber = _phoneNumberController.text;
String verifyCode = _verifyCodeController.text;
String password = _passwordController.text;
AGCAuthCredential credential = PhoneAuthProvider.credentialWithVerifyCode(countryCode, phoneNumber, verifyCode, password: password);
AGCAuth.instance.signIn(credential).then((value) {
setState(() {
_log = 'signInWithVerifyCode = ${value.user.uid} , ${value.user.providerId}';
});
});
}

• 邮箱账号：调用signIn方法，传入通过邮箱、验证码和密码生成的认证凭据。

_signInWithVerifyCode() async {
bool result = await _showEmailDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String email = _emailController.text;
String verifyCode = _verifyCodeController.text;
String password = _passwordController.text;
AGCAuthCredential credential = EmailAuthProvider.credentialWithVerifyCode(
email, verifyCode,
password: password);
AGCAuth.instance.signIn(credential).then((value) {
setState(() {
_log =
'signInWithVerifyCode = ${value.user.uid} , ${value.user.providerId}';
});
});
}

1. 自有账号

自有账号创建jwt获取token等步骤为server端步骤，端侧只需要取到token进行登录即可。

_signIn() async {
bool result = await _showSelfBuildDialog(VerifyCodeAction.registerLogin);
if (result == null) {
print("cancel");
return;
}
String token = _selfBuildController.text;
AGCAuthCredential credential = SelfBuildAuthProvider.credentialWithToken(token);
AGCAuth.instance.signIn(credential).then((value) {
setState(() {
_log = 'signIn = ${value.user.uid} , ${value.user.providerId}';
});
});
}

1. 打包

与Android相同，只需要在Android Studio中点击运行即可
