我仍然是 Firebase 世界的初学者,我一直在尝试找出以下代码的问题所在,但我在所有可能的方面都失败了。
该代码应该检索uid
来自数据库中的用户配置文件,然后使用它来更新身份验证配置文件,如果身份验证配置文件更新成功,则再次更新数据库配置文件。
In index.js
我定义了一个导出函数来处理 HTML 表单中的 POSTed 参数。下面的代码在另一个模块文件中定义了处理函数:
exports.auUpdateUserByEmail = (req, res) => {
// This handler function will retrieve the POSTed params of user profile
// and will attempt to update the existing user authentication as well as
// the database profiles.
//
// This function accepts the following params:
// 1. User email // 2. Phone number // 3. password // 4. Display name
// 5. Photo url // 6. Disabled Flag
//
var db = admin.firestore();
var uEmail = req.body.userEmail;
var dName = req.body.displayName;
var userId = "";
var newuser = {
displayName: dName
}
console.log("Email passed: " + uEmail);
// Fetch the user UID by user email...
res.write('User UID: ' + userId);
console.log('User UID: ' + userId);
// attempt to update the user authentication profile...
return db.collection('Users').where('email', '==', email).get()
.then(snapshot => {
snapshot.forEach(doc => {
var d = doc.data();
console.log("doc.id: " + doc.id + " - d.email: " + d.email);
if(d.email == email)
{
userId = d.uid;
}
});
return admin.auth().updateUser(userId, newuser);
}).then(function(userRecord) {
// The updating was successful... Attempt to update User Details in
// database User Profile...
console.log("User Updated Successfully. UID: " + userRecord.uid);
retUid = userRecord.uid;
// Create a reference to the Users Database...
var docRef = db.collection('Users');
// Update the user profile document.
return docRef.doc(userRecord.uid).update(newuser);
}).then(result => {
// everything went fine... return User UID as a successful result...
res.write(userId);
return res.end();
}).catch(function(error) {
console.log("doc.update - Error updating user profile in database:", error);
return res.end();
});
}
In index.js
,我有以下导出定义:
var appAuth = express();
//Here we are configuring express to use body-parser as middle-ware.
appAuth.use(bodyParser.urlencoded({ extended: false }));
appAuth.use(bodyParser.json());
appAuth.post('/updateUserByEmail', authusers.auUpdateUserByEmail);
exports.usersAuthFunctions = functions.https.onRequest(appAuth);
我不得不说我让它工作得很好以获得uid
,更新身份验证配置文件,然后更新数据库配置文件,但它一直等待函数返回。
感谢您的宝贵帮助。谢谢。
我已经更新了代码,如下所示,它完成了工作,但在承诺完成之前返回一个空白页面,因为 HTTPS 退出了“错误:在结束后写入” error.
var fetch_uid = db.collection('Users').where('email', '==', uEmail).get()
.then(snapshot => {
// var userId = snapshot.data.uid;
snapshot.forEach(doc => {
var d = doc.data();
console.log("doc.id: " + doc.id + " - d.email: " + d.email);
if(d.email == uEmail)
{
userId = d.uid;
res.write('User UID: ' + userId);
console.log('User UID: ' + userId);
}
});
return admin.auth().updateUser(userId, newuser);
}).then(function(userRecord) {
// The updating was successful... Attempt to update User Details in
// database User Profile...
console.log("User Updated Successfully. UID: " + userRecord.uid);
retUid = userRecord.uid;
// Create a reference to the Users Database...
var docRef = db.collection('Users');
// Update the user profile document.
return docRef.doc(userRecord.uid).update(newuser);
}).then(result => {
// everything went fine... return User UID as a successful result...
res.write(userId);
return;
}).catch(function(error) {
console.log("doc.update - Error updating user profile in database:", error);
return;
});
res.end();
