由于访问控制检查,XMLHttpRequest无法加载https://firestore.googleapis ..... [英] XMLHttpRequest cannot load https://firestore.googleapis..... due to access control checks
问题描述
我正在尝试在我的项目中实现firestore。
我现在正在做的只是实现它并读取一些数据,但我在标题中得到错误:
I'm trying to implement firestore in my project. What I'm doing right now is just implementing it and read some data, but I get the error in the title :
XMLHttpRequest无法加载 https://firestore.googleapis.com/google.firestore .....由于访问控制检查。
XMLHttpRequest cannot load https://firestore.googleapis.com/google.firestore..... due to access control checks.
我使用以下内容:
// Initialize Firebase
var config = {
apiKey: "xxx",
authDomain: "xxx",
databaseURL: "xxx",
projectId: "xxx",
storageBucket: "xxx",
messagingSenderId: "xxx"
};
firebase.initializeApp(config);
// Initialize Cloud Firestore through Firebase
var db = firebase.firestore();
var docRef = db.collection("users");
docRef.get().then(function(querySnapshot) {
querySnapshot.forEach(function(doc) {
//alert(doc.data().born);
});
})
.catch(function(error) {
console.log("Error getting documents: ", error);
});
我尝试检索数据的部分导致错误(docRef.get()... )
The part where I try to retrieve the data cause the error (docRef.get()...)
你知道为什么会发生这个错误吗?
Do you have an idea why is this error happening ?

推荐答案
听起来您需要更新Firestore安全规则。您可以通过Firebase控制台网站中数据库页面的规则标签执行此操作。
Sounds like you need to update your Firestore Security Rules. You can do this via the "Rules" tab of the Database page in the Firebase Console website.
有关Firestore规则的文档位于: https://firebase.google.com/docs/firestore/security/get-started
Docs about Firestore Rules are here: https://firebase.google.com/docs/firestore/security/get-started
您可以使用此规则集使任何人都可以访问它。我会使用这些规则来确保您能够解决问题。之后,我会调整您的规则,使其符合您的应用数据所需的安全性(或敏感度)。
You can use this ruleset to make it accessible to anyone. I would use these rules just to make sure that you were able to fix your problem. After that, I would tweak your rules so they match the amount of security (or sensitivity) your app's data needs.
service cloud.firestore {
match / databases / {database} / documents {
match / {document = **} {
allow read,write:if true;
}
}
}
