I am very new to node js. I am just testing some stuff about client-server communication.
I have these codes:
server:
app.post('/zsa', (req, res) => {
res.send("zsamo");
});
client:
fetch("http://localhost:3000/zsa", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(data),
})
.then((data) => {
console.log(data);
});
With this code i get a response object:
I want to log to the console what was in the response data: "zsamo"
fetch returns a Response. If you want JSON from the body of your response then you can do this:
fetch(url)
.then(response => response.json())
.then(data => console.log(data));
See also Using the Fetch API
response.text() instead of response.json() and don't send your response from the server with the Content-Type application/json but instead use text/plain
res.send('"zsamo"')
At client side, in console.log instead of data, write data.body
zsamois not JSONres.send("zsamo")). Beware thatJSON.parse("zsamo")in a modern browser will still produce SyntaxError: Unexpected token 'z', "zsamo" is not valid JSON ButJSON.parse('"zsamo"')will result in a string with the content:zsamo. See this answerzsamois not JSON.
