获取邮递员发送的二进制文件数据？

Question

我正在尝试获取从 nodejs 中的邮递员的二进制选项发送的数据，但是当我打印 req.body 时它返回空白对象。 谁能告诉我如何获取这些数据？

代码：

const express = require("express");
const app = express();
const bodyParser = require('body-parser');

app.use(bodyParser.text()); // This will parse your file

app.post('/data/UploadLogsToServer', async (req, res) => {
   res.status(200).send(req.body)
});

const server = app.listen(3000, function () {
    console.log('Server listening on port 3000');
});

Foo.txt 文件

在 Postman 中，确保您的标题具有 Content-Type = application/octet-stream。然后在您的app.post 定义中，分块读取数据。例如，下面它返回一个简单的 JSON 响应，但至少服务器看到了数据。您的版本似乎没有：

    var data = '';
    app.post('/data/UploadLogsToServer',function(req, res) {

    req.on('data', function(chunk) {
      data += chunk;
    });

    req.on('end', function() {
      console.log(data);
    });

    var responseJson = {
      "message": "success!!!"
    };

    return res.status(200).send(responseJson);
  });
