在用户注册时如何将其添加到现有角色?我下面的代码不起作用,日志中没有任何错误或打印(不确定我在做什么):
Parse.User.signUp(req.body.email, req.body.password, {
"name": req.body.name,
"email": req.body.email,
}, {
success: function(user) {
var query = new Parse.Query(Parse.Role);
query.equalTo("name", 'Basic User');
query.find({
success: function(roles) {
alert("HELLO" + roles);
if (roles.length < 1) {
alert("HELLO");
console.log("Error Signing Up: No roles for " + signUpRoleGroup + " were found");
} else {
alert("HERE");
roles[0].getUsers().add(user);
roles[0].save();
}
},
error: function(error) {
alert("Could not add users to the account " + accountName + " error: " + error.message);
}
});
},
error: function(user, error) {
alert("Error signing up user");
}
});
最佳答案
我认为发生了什么事,就是呼叫者没有给此功能一个完成保存角色的机会。在调用response.success()或error()之前,云函数应该等待直到角色被保存。
这是对相同代码的承诺返回重写。我认为,对序列进行的异步任务更轻松,也更清楚。这使您可以更牢固地控制响应。
Parse.Cloud.define("signupAsBasicUser", function(request, response) {
signupAsBasicUser(request.params.name, request.params.password, request.params.email).then(function(user) {
response.success(user);
}, function(error) {
response.error(error);
});
});
// return a promise fulfilled with a signed-up user who is added to the 'Basic User" role
//
function signupAsBasicUser(name, password, email) {
Parse.Cloud.useMasterKey();
var user = new Parse.User();
user.set("username", name);
user.set("password", password);
user.set("email", email);
return user.signUp().then(function() {
var query = new Parse.Query(Parse.Role);
query.equalTo("name", 'Basic User');
return query.find();
}).then(function(roles) {
if (roles.length < 1) return Parse.Promise.error("no such role");
roles[0].getUsers().add(user);
return roles[0].save();
}).then(function() {
return user;
});
}
