Express.js发送数据以通过发布获取请求

Question

I've a form with express.js:

app.get("/", function (req, res) {
  if (req.body.something) {
    // Do something
  }
  res.send(myform);
});
app.post("/", function (req, res) {
  if (req.body.foobar == false) {
     // I need to set req.body.something and make it visible to "get"
  }}
});

My form:

<form method="post" action="/">
  <input type="checkbox" name="foobar">
  <input type="submit" value="submit">
</form>

I need a way to send data with "post" method and make it visible by the "get" method. How can I do?

Answer 1

There are probably a number of ways to do this. One option is to store the POST values in a session.

app.post("/", function (req, res) {
  if (req.body.foobar == false) {
    //Store foobar from body of POST into the session
    req.session.foobar = req.body.foobar;
    // Other stuff...
  }}
});

app.get("/", function (req, res) {
  if (req.body.something) {
  // Do something
     doStuff(req.session.foobar) // Here we use the foobar set in POST
     //DO MORE STUFF
  }
  res.send(myform);
});

To use this before add something similar to below enable sessions.

app.use(session({secret: 'fabecefd-387c-4dc9-a525-25d1fab00330'}));

Additional note: Please validate your input, handle error conditions, and structure your code your own way. The above was a very basic example on how to use sessions.

You can send data with the GET method using jQuery :

$.ajax({
  type: 'GET',
  data: 'Your body content here'
});

Or using curl from a terminal :

curl -XGET -d "Your body content" http://localhost:3000/

app.get("/", function (req, res) {
  if (req.body.something) {
    app.get('setKey');
  }
 res.json(req.body);
});

app.post("/", function (req, res) {
 if (req.body.foobar == false) {
   app.set('setKey','setValue');
 }}
});
