Question

我的node.js脚本正在接收来自Google Chrome扩展程序邮递员的HTML POST请求调用，但它没有看到键值对。继续给我

TypeError: Cannot read property 'username' of undefined
   at app.get.params.QueueUrl (/home/ec2-user/Outfitr/Server/index.js:45:53)
    at Layer.handle [as handle_request] (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/layer.js:82:5)

这是我的代码。如果您还有其他需要，请告诉我

app.post('/bscreateuser', function(request, response) {
  process.stdout.write("Attempted to create a --- BBBSSSSS ---- user  |  ");
  process.stdout.write("request is " + request.url);
  process.stdout.write("username is " + request.body.username);
  process.stdout.write("Password is " + request.body.password);
  bscreateUser(request.query.username, request.body.password);
  response.send('Success' );
});

function bscreateUser(username, password) {
  messageBody = 'create_user("' + username + '","' + password + '")';
  queueUrl = DAO_QUEUE_URL;
  // sys.puts("--- going for BS ---");
  sendSQSMessage(JSON.stringify(messageBody), queueUrl);
}

Answer 1

 bscreateUser(request.query.username, request.body.password);

应该是：

 bscreateUser(request.body.username, request.body.password);

将来避免这种情况的好方法是：

var body = request.body;
var username = body.username;
var password = body.password

然后在代码中使用var username和var password，更不容易出错，而且更具可读性！

Node.js没有读取HTML POST请求
