【问题描述】：
我收到以下错误：(index):24 POST https://goldengates.club:3000/api/transact net::ERR_SSL_PROTOCOL_ERROR
(anonymous) @ (index):24
goldengates.club/:1 Uncaught (in promise) TypeError: Failed to fetch
Promise.then (async)
(anonymous) @ (index):26 尝试从客户端向我的 api 后端发出发布请求时。我已经使用 express 打开了端口 3000，以便在客户端将数据发布到的名为 api/transact 的端点上接受请求。问题似乎出在我当前的 ssl 上，但我不知道具体是什么问题。
我与服务器提供商联系，他们告诉我引用“您可能需要重新配置在端口 3000 上运行的应用程序以使用 SSL 加密数据。如果您需要证书文件，它们应该在用户帐户的 ssl 目录中可用。”万一这给出了提示。
相关服务器API代码：
const Blockchain = require('./blockchain');
const PubSub = require('./app/pubsub');
const TransactionPool = require('./wallet/transaction-pool');
const Wallet = require('./wallet');
const TransactionMiner = require('./app/transaction-miner');
const PubSubNub = require('./app/pubsub.pubnub');
//127.0.0.1:6379
const isDevelopment = process.env.ENV === 'development';
//TRY PUBNUB (comment out)
/*const REDIS_URL = isDevelopment ?
'redis://127.0.0.1:6379' : //try 6379 19289

const DEFAULT_PORT = 3000;
const ROOT_NODE_ADDRESS =

const app = express();
const blockchain = new Blockchain();
const transactionPool = new TransactionPool();
const wallet = new Wallet();
//const pubsub = new PubSub({ blockchain, transactionPool, redisUrl: REDIS_URL });//redis
const pubsub = new PubSubNub({ blockchain, transactionPool, wallet }); // for PubNub //change back to PubSub if issues arise
const transactionMiner = new TransactionMiner({ blockchain, transactionPool, wallet, pubsub });
//DELETE THIS
