I am having issue with app.get("/posts/:postName",function(req, res){ and const storedTitle =req.body.postTitle; The issue is whenever I run http://localhost:3000/posts/Test in browser I am suppose to get output as match found but when I console log storedTitle to debug I get it as undefined istead of Test. output screenshot: output image These are pictures of /compose ejs file. compose.ejs

CodePudding user response：

Instead of const storedTitle =req.body.postTitle; you should use const storedTitle = post.title;

CodePudding user response：

You get undefined in log because, of the following lines:

const storedTitle =req.body.postTitle; 
console.log(storedTitle);

Because, GET requests does not have body.

Change those lines as follows:

const storedTitle = post.title; 
console.log(storedTitle);

I suppose it is a copy/paste error from /compose handler :-)

Good day!

CodePudding user response：

You cannot use req.body in a GET request It should either use POST app.post("/posts/:postName",....

or

const storedTitle =req.query.postTitle;
