arangodb，如何从发布请求中检索JSON

Question

I'm posting a JSON message to an endpoint in my foxx microservice. It's unclear to me how to get the complete JSON in order to parse it:

router.post('/storeDataRecord', (req, res) => {

....

}).body('deviceData');

This is the json:

{
    “data”: [
        {
            “id”: “identifier”,
            “key1”: “value1”,
            “key2”: “value2”
        }
    ]
}

I've tried with

var request = req.body.deviceData;
var request = req.body.get('data');

can you help me to understand how to navigate the json?

Answer 1

Here is a minimal, complete, working example of a post-request route accepting a json body :

var joi = require('joi');
var processJson = function(jsonObject) {
    return JSON.stringify(jsonObject);
};
router.post('/start', function(req, res) {
    var result = processJson(req.body);
    res.json({'result': result});
}).summary('Json example').body(joi.object().unknown(true), ['json']);

Notice that the accepted content-type is declared ( ['json'] , shorthand for ['application/json'] )

Of course this assumes the data you post is actually valid JSON, but if it is not, you should see errors on the sending side (debug into the sending code and inspect the data you pass), or at least an error from arangodb indicating invalid data in the request.
