Question

我正在尝试使用node.js连接Firebase

我的json文件中包含以下代码。

    const functions = require('firebase-functions');
    const hmac_sha256= require ('crypto-js/hmac_sha256');
    const request= require('request');
    const admin= require('firebase-admin');
    
    const service_Account= require('./service_account_key.json');
    const firebaseConfig= json.parse(process.env.FIREBASE_CONFIG);
    firebaseConfig.credential= admin.credential.cert("service_Account");
    admin.initializeApp(firebaseConfig);
    
    exports.getCustomToken = functions.https.onRequest((req,res)=>{
        const  accessToken= req.query.access_Token;
        const FacebookAppSec= '72100b8d4ee21a85fc67d014f3b0c9fa';
        const AppSecretProof= hmac_sha256(accessToken,FacebookAppSec);
        //Validate token...
        const uri='https://graph.accountkit.com/v1.1/me?access_Token=${accessToken}&App_Proof=${AppSecretProof}';
    
    request({
            url= uri,
            json:true
    },(error,fbresponse,data)=>{
        if(error)
        {
            console.error('Access Token validation request failed\n',error);
            res.status(400).send(error);
        }
        else if(data.error)
        {
            console.error('Invalid Access Token\n',
                'access_Token=${accessToken}',
                'App_Proof=${AppSecretProof}',data.error);
            res.status(400).send(data);
        }
        else
        {
            admin.auth().createCustomToken(data.id)
            .then(CustomToken => res.status(200).send(CustomToken))
            .catch(error => {
                console.error('Create Custom Token Failed.',error);
                res.status(400).send(error);
            })
        }
            
    
    })
    
    })

使用Command-firebase部署后，我得到了

我在堆栈溢出和github上都看到了很多答案，但是没有任何反应。我已经尽力通过myown解决了这个问题，也从在线社区获得了帮助，但现在将其发布给大家。

输出显示ESLint在index.js的第19行上给您此错误消息：

19：9错误解析错误：简写属性分配仅在解构模式下有效

第19行位于下面的url= uri：

request({
        url= uri,
        json:true
},(error,fbresponse,data)=>{

如果要为JavaScript对象中的属性赋值，则必须使用:而不是=，就像使用json:true一样。

request({
        url: uri,
        json:true
},(error,fbresponse,data)=>{

您能帮我解决有关json的错误吗？
