【英文标题】：ios: Having problem with posting data to Firestore

【发布时间】：2019-04-03 20:01:39

【问题描述】：

我正在尝试将数据发布到 Firebase。但是当我点击我的按钮时，什么也没有发生。既没有数据发送也没有任何异常发生。我尝试了很多方法，也尝试了新项目，但问题仍然存在。我已经尝试了 Firebase 网站上给出的测试代码，没有任何反应。

这是我的常量

let THOUGHTS_REF = "thoughts"

let CATEGORY = "category"

let NUM_COMMENTS = "numComments"

let NUM_LIKES = "numLikes"

let THOUGHT_TXT = "thoughtTxt"

let TIMESTAMP = "timestamp"

let USERNAME = "username"

**这里是 ThoughtCategory 的枚举 **

enum ThoughtCategory: String 

    case serious = "serious"
    case funny = "funny"
    case crazy = "crazy"
    case popular = "popular"

这是 VIEW 背后的代码：

import UIKit
import Firebase
import FirebaseFirestore

class AddThoughtVC: UIViewController, UITextViewDelegate 


    //Outlets
    @IBOutlet weak var segmentControl: UISegmentedControl!
    @IBOutlet weak var usernameTxt: UITextField!
    @IBOutlet weak var thoughtTxt: UITextView!
    @IBOutlet weak var postBtn: UIButton!

    //Variables
    private var categorySelected = ThoughtCategory.funny.rawValue


    override func viewDidLoad() 
        super.viewDidLoad()
        thoughtTxt.delegate = self

        postBtn.layer.cornerRadius = 4
        thoughtTxt.layer.cornerRadius = 4
        thoughtTxt.text = "My random thought..."
        thoughtTxt.textColor = UIColor.lightGray
    

    func textViewDidBeginEditing(_ textView: UITextView) 
        textView.text = ""
        textView.textColor = UIColor.darkGray
    

    @IBAction func categoryChanged(_ sender: Any) 

        switch segmentControl.selectedSegmentIndex 
        case 0:
            categorySelected = ThoughtCategory.funny.rawValue
        case 1:
            categorySelected = ThoughtCategory.serious.rawValue
        default:
            categorySelected = ThoughtCategory.crazy.rawValue
        

    

    @IBAction func postBtnTapped(_ sender: Any) 

        guard let username = usernameTxt.text else  return 

            Firestore.firestore().collection(THOUGHTS_REF).addDocument(data: [

            CATEGORY : categorySelected,
            NUM_COMMENTS : 0,
            NUM_LIKES : 0,
            THOUGHT_TXT : thoughtTxt.text,
            TIMESTAMP : FieldValue.serverTimestamp(),
            USERNAME : username


        ])  (err) in
            if let err = err 
                debugPrint("Error adding document: \(err)")
             else 
                self.navigationController?.popViewController(animated: true)
            
        

    

这是日志文件中的错误

【问题讨论】：

检查 Firestore 控制台上的安全规则。我认为您的应用程序无权访问 Firestore。检查控制台的规则选项卡。

谢谢，问题解决了

@Usama 你是如何解决这个问题的？我有同样的问题。安全规则设置为 public3

有关如何解决此问题的更多信息？

我刚刚将安全规则更改为公共@BradThomas Read: true Write: true

【参考方案1】：

Check Firestore rules
rules_version = '1';

service cloud.firestore 
  match /databases/database/documents 
    match /document=** 
      allow read, write;
