问题描述

由于控制台显示设置/number失败，因此无法将NodeMCU与Firebase连接:每次 在Firebase上也没有更新.

Unable to connect NodeMCU with Firebase as console shows setting /number failed: each time No updation on firebase as well.

还是应该更改云服务器?

or should I change the cloud server?

    #include <ESP8266WiFi.h>
    #include <FirebaseArduino.h>

    // Set these to run example.
    #define FIREBASE_HOST "example.firebaseio.com"
    #define FIREBASE_AUTH "token_or_secret"
    #define WIFI_SSID "SSID"
    #define WIFI_PASSWORD "PASSWORD"

    void setup() {
      Serial.begin(9600);

      // connect to wifi.
      WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
      Serial.print("connecting");
      while (WiFi.status() != WL_CONNECTED) {
        Serial.print(".");
        delay(500);
      }
      Serial.println();
      Serial.print("connected: ");
      Serial.println(WiFi.localIP());

      Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
    }

    int n = 0;

    void loop() {
      // set value
      Firebase.setFloat("number", 42.0);
      // handle error
      if (Firebase.failed()) {
          Serial.print("setting /number failed:");
          Serial.println(Firebase.error());  
          return;
     }
      delay(1000);
    }

推荐答案

Firebase Arduino库具有对Firebase SSL证书指纹的引用.该指纹可能与当前指纹不匹配.

The Firebase Arduino library has a reference to a fingerprint of the Firebase SSL certificate. This fingerprint may not match the current fingerprint.

此指纹在FirebaseHttpClient.h中(通常在C:\Users\<User>\Documents\Arduino\libraries\firebase-arduino-<version>\src\FirebaseHttpClient.h中).

This fingerprint is in FirebaseHttpClient.h (typically in C:\Users\<User>\Documents\Arduino\libraries\firebase-arduino-<version>\src\FirebaseHttpClient.h).

要查找并更改当前指纹，请执行以下操作:

To find and change the current fingerprint:

1. 转到 https://www.grc.com/fingerprints.htm
2. 输入"test.firebaseio.com"
3. 记录指纹(例如，当前为03:D6:42:23:03:D1:0C:06:73:F7:E2:BD:29:47:13:C3:22:71:37:1B
4. 打开C:\Users\<User>\Documents\Arduino\libraries\firebase-arduino-<version>\src\FirebaseHttpClient.h
5. 用指纹替换kFirebaseFingerprint的值(不带冒号)
6. 重新编译

1. Go to https://www.grc.com/fingerprints.htm
2. Enter "test.firebaseio.com"
3. Record the fingerprint (e.g. it is currently 03:D6:42:23:03:D1:0C:06:73:F7:E2:BD:29:47:13:C3:22:71:37:1B
4. OpenC:\Users\<User>\Documents\Arduino\libraries\firebase-arduino-<version>\src\FirebaseHttpClient.h
5. Replace value of kFirebaseFingerprint with the fingerprint (without colons)
6. Recompile

例如以下指纹在此时间点有效:

e.g. the following fingerprint works at this point of time:

static const char kFirebaseFingerprint[] =
  "03 D6 42 23 03 D1 0C 06 73 F7 E2 BD 29 47 13 C3 22 71 37 1B";
