我正在尝试使用默认的通过Facebook登录名登录应用程序,但是我无法获取用户的电子邮件。
这是我的按钮:
<LoginButton
publishPermissions={["email"]}
onLoginFinished={
(error, result) => {
if (error) {
alert("Login failed with error: " + error.message);
} else if (result.isCancelled) {
alert("Login was cancelled");
} else {
alert("Login was successful with permissions: " + result.grantedPermissions)
}
}
}
onLogoutFinished={() => alert("User logged out")}
/>
这是我尝试获取用户详细信息的方式:
async FBGraphRequest(fields, callback) {
const accessData = await AccessToken.getCurrentAccessToken();
console.log("token= ", accessData.accessToken )
// Create a graph request asking for user information
const infoRequest = new GraphRequest('/me', {
accessToken: accessData.accessToken,
parameters: {
fields: {
string: fields
}
}
}, this.FBLoginCallback.bind(this));
// Execute the graph request created above
new GraphRequestManager().addRequest(infoRequest).start();
}
async FBLoginCallback(error, result) {
if (error) {
this.setState({
showLoadingModal: false,
notificationMessage: "facebook error"
});
} else {
// Retrieve and save user details in state. In our case with
// Redux and custom action saveUser
this.setState({
id: result.id,
email: result.email,
name: result.name
});
console.log("facebook login",result)
}
}
console.log("facebook login",result)
行仅向我返回帐户名和ID,但没有用于发送电子邮件的字段...
我在做什么错?
PS .:我也尝试过使用“自定义功能”,但是它也不起作用(对于电子邮件,登录有效,并且我仅获得用户详细信息,例如姓名和ID):
async facebookLogin() {
// native_only config will fail in the case that the user has
// not installed in his device the Facebook app. In this case we
// need to go for webview.
let result;
try {
this.setState({showLoadingModal: true});
LoginManager.setLoginBehavior('NATIVE_ONLY');
result = await LoginManager.logInWithReadPermissions(['public_profile', 'email']);
} catch (nativeError) {
try {
LoginManager.setLoginBehavior('WEB_ONLY');
result = await LoginManager.logInWithReadPermissions(['email']);
} catch (webError) {
// show error message to the user if none of the FB screens
// did not open
}
}
console.log("facebook result 1: ", result)
// handle the case that users clicks cancel button in Login view
if (result.isCancelled) {
this.setState({
showLoadingModal: false,
notificationMessage: I18n.t('welcome.FACEBOOK_CANCEL_LOGIN')
});
} else {
// Create a graph request asking for user information
this.FBGraphRequest('id, email, name', this.FBLoginCallback);
}
}

<LoginButton
publishPermissions={["email"]}
onPress={
this.facebookLogin()
}
onLogoutFinished={() => alert("User logged out")}
/>
!!! 已解决 !!!
<权限的道具是“ permissions”,而不是“ readPermission” ...
所以按钮代码是:
<LoginButton
permissions={['public_profile', 'email', 'user_birthday', ]}
onClick={this.facebookLogin}
/>
