在 Node JS 中分块数据

Chunking Data in Node JS

我是 node 的新手,我无法理解为什么你会 "Chunk" 数据只在 POST 请求而不是 GET 请求?

if (request.method === "POST") {
  if (request.url === "/classes/messages" || request.url === "/classes/room1") {
    var statusCode = 201;
    var headers = defaultCorsHeaders;
    var body = '';
    request.on('data', function(data) {
      console.log("receiving data....", body);
      body += data;
    });
    //request ended, you can now do something with the data
    request.on('end', function() {
      var bodyObj = JSON.parse(body);
      bodyObj.objectId = Math.random() * 10;
      responseObj['results'].push(bodyObj);
      // request ended -> do something with the data. set the headers. 
      response.writeHead(statusCode, headers);
      //writing the data to json
      //response.write();
      //ending the response. 
      response.end(JSON.stringify(responseObj));
    });
    //headers['Content-Type'] = "text/plain";
  }
}

当使用 POST 方法时,用户将数据发送到服务器,我们需要分析,因此需要查出所有数据。 使用GET服务器向用户发送数据时,服务器取不到数据,不需要chuck
