OK so why are the request parameters with complex objects so poorly parsed in the Backend Service

context.request

compared to a Suitlet or RESTlet script? Here is an example: I am getting the cart items and sending it to the backend as an object. Usually as a POST I would catch by doing

JSON.parse(request.body)

Copy code

cartComponent.getLines()
                    .then((lines) => {
                        this.model
                            .fetch({
                                type: "post",
                                data: {
                                    action: "updateOrder",
                                    session: this.session,
                                    lines: lines

                                }
                            })
                            .done(response => {
                                console.debug({ response: response });
                            })
                            .catch(reason => {
                                console.error({ title: "ERROR_UPDATING_ORDER", reason: reason });
                            });
                    });

I have tried logging request in the backend and both aren't well structured. I have tried logging the body.

Copy code

function doPost(context) {
    log.debug({
        title: "doPost body audit",
        details: {
            body: context.request.body
        }
    });

    log.debug({
        title: "doPost body JSON audit",
        details: {
            body: JSON.parse(context.request.body)
        }
    }); // fails with error SyntaxError: Unexpected token:
}

This is essentially what I get.

Copy code

{"body":"action=updateOrder&session%5Borderid%5D=2550927&session%5Btranid%5D=SO76470&session%5Bshipdate%5D=7%2F5%2F2022&session%5Bmode%5D=editorder&lines%5B0%5D%5Bextras%5D%5Brate_formatted%5D=%240.00&lines%5B0%5D%5Bextras%5D%5Btax_rate1%5D=&lines%5B0%5D%5Bextras%5D%5Btax_type1%5D=&lines%5B0%5D%5Bextras%5D%5Btax_rate2%5D=&lines%5B0%5D%5Bextras%5D%5Btax_type2%5D=&lines%5B0%5D%5Bextras%5D%5Btax1_amount%5D=&lines%5B0%5D%5Bextras%5D%5Btax1_amount_formatted%5D=%240.00&lines%5B0%5D%5Bextras%5D%5Bdiscount%5D=0&lines%5B0%5D%5Bextras%5D%5Bpromotion_discount%5D=&lines%5B0%5D%5Bextras%5D%5Btotal%5D=0&lines%5B0%5D%5Bextras%5D%5Bfree_gift%5D=false&lines%5B0%5D%5Bextras%5D%5Bamount_formatted%5D=%240.00&lines%5B0%5D%5Bextras%5D%5Btax_amount_formatted%5D=%240.00&lines%5B0%5D%5Bextras%5D%5Bdiscount_formatted%5D=%240.00&lines%5B0%5D%5Bextras%5D%5Btotal_formatted%5D=%240.00&lines%5B0%5D%5Binternalid%5D=item8518set165186&lines%5B0%5D%5Bquantity%5D=2&lines%5B0%5D%5Brate%5D=0&lines%5B0%5D%5Bamount%5D=0&lines%5B0%5D%5Bitem%5D%5Bextras%5D%5Bisinstock%5D=true&lines%5B0%5D%5Bitem%5D%5Bextras%5D%5Bweightunit%5D=...

I have tried logging the parameters.

Copy code

function doPost(context) {
    log.debug({
        title: "doPost parameters audit",
        details: {
            parameters: context.request.parameters
        }
    });
}

This is what I get.

Copy code

How would you parse a POST request body that has a complex object?

Have you tried

request.getParameter("xyz");

Chris

In other words, get a handle on what you posted, then you can parse it.

Creates an error.

Copy code

Cannot find function getParameter in object http.ServerRequest

Copy code

data: { $.param({
    action: "updateOrder",
    session: this.session,
    lines: lines })

Try sending it up to the back-end like that.

Came out the same on the backend.

Marvin

OK I think I figured it out. Send like this.

Copy code

data: JSON.stringify({
    action: "updateOrder",
    session: this.session,
    lines: lines })

Catch like this.

Copy code

const params = JSON.parse(JSON.parse(context.request.body));

Gotta turn your object into text or you send up some weird representation of the object.
