Question

我在尝试从客户端向我的api后端发出发布请求时收到以下错误：(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。我已经使用express打开了端口3000，以在客户端向其发布数据的名为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。我在服务器提供商处签到，他们告诉我“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。如果需要证书文件，则应在用户帐户的ssl目录中提供这些文件。”万一这提示。

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
  'redis://h:p602b6838e89da65c8c4d29a6a4f954452d1ece59c10b27a29ebf9808721cb8e2@ec2-35-153-115-238.compute-1.amazonaws.com:9819'//19289
*/  
const DEFAULT_PORT = 3000;
const ROOT_NODE_ADDRESS = 
`http://localhost:${DEFAULT_PORT}`;

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
/*const config =
{
    headers: {'Access-Control-Allow-Origin':'*'}
};*/
//TEST DELETE

app.use(bodyParser.json());
app.use(express.static(path.join(__dirname, 'client/dist')));
//delete below
//app.options('*', cors());

app.use(cors({
    origin: 'https://goldengates.club',
    allowedHeaders: ["Content-Type"],
    methods: 'POST'
}));

SKIPPING TO FoCUSED ENDPOINT...

app.post('/api/transact',(req, res) => {

  const { amount, recipient } = req.body;
  //REMOVE
  console.log(amount);
  //REMOVE
  let transaction = transactionPool
    .existingTransaction({ inputAddress: wallet.publicKey });

  try {
    if (transaction) {
      transaction.update({ senderWallet: wallet, recipient, amount });
    } else {
      transaction = wallet.createTransaction({
        recipient,
        amount,
        chain: blockchain.chain
      });
    }
  } catch(error) {
    return res.status(400).json({ type: 'error', message: error.message });
  }

  transactionPool.setTransaction(transaction);

  pubsub.broadcastTransaction(transaction);

  res.json({ type: 'success', transaction });
});

    <script>
        const amount=10;

        const options=
        {
            method: 'POST',
            headers:
            {
                'Content-Type': 'application/json',
            },

            body: JSON.stringify(data)
        };
        fetch('https://www.goldengates.club:3000/api/transact',options)
        .then(response => response.json())
        .then(data => console.log(data));

https://goldengates.club:3000/api/transact net::ERR_SSL_PROTOCOL_ERROR

您在端口3000上的应用程序未针对HTTPS设置，而仅针对HTTP。尝试使用HTTPS访问普通HTTP服务器会导致您看到错误。请注意，您不能简单地在客户端中用http://host:port切换https://host:port并期望服务器可以通过HTTPS神奇地使用。

...他们告诉我说：“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。如果需要证书文件，则应在用户帐户的ssl目录中提供它们。”

他们指出的完全一样。

除此之外，使用HTTPS公开nodejs API的一种常用方法不是使nodejs服务器本身具有HTTPS功能，而是针对诸如nginx之类的反向代理对其进行隐藏-例如参见Configuring HTTPS for Express and Nginx。

SSL_PROTOCOL_ERROR，发布请求，客户端，api，ssl
