I have a server as following:
app.post('/', function(req, res, next) {
console.log(req);
res.json({ message: 'pppppppppppppssssssssssssss ' });
});
The request is sent from a client as:
$.ajax({
type: "POST",
url: self.serverURI,
data: JSON.stringify({ "a": "128", "b": "7" }),
dataType: 'json',
success: function (result) {
console.log(result);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr);
}
});
so far the connection fine.
My problem is in the server:
console.log(req);
where I want to read the data I sent. How can I read { "a": "128", "b": "7" }
from req
?
Any JSON data can be consumed from different sources like a local JSON file by fetching the data using an API call. After getting a response from the server, you need to render its value. You can use local JSON files to do an app config, such as API URL management based on a server environment like dev, QA, or prod.
Although you're not mentioning it, your code looks like it's written for an Express environment. My answer is targeted to this.
Make sure to use body-parser
for Express. In case, your project depends on some generated boilerplate code, it's most likely already included in your main server script. If not:
var bodyParser = require('body-parser');
app.use(bodyParser.json());
Installation with npm: npm install body-parser --save
The parsed JSON can then be accessed through req.body
:
app.post('/', function(req, res, next) {
console.log(req.body); // not a string, but your parsed JSON data
console.log(req.body.a); // etc.
// ...
});
