贝宝快速结帐-400错误的要求

Question

I'm using this instruction https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/advanced-integration/ to set up paypal. The only different is that I need to send data to CREATE_PAYMENT_URL endpoint, so I transfer it as second parameter

paypal.request.post(
                CREATE_PAYMENT_URL,
                JSON.stringify([{"name": "test", "price": 10}]),
                { headers: { 'Content-Type': 'application/json' } }

            )

after that I'm getting 400 error

{"success":false,"errors":{"statuscode":400,"message":"Invalid json message received"}}

Backend doesn't matter, cause it's never reached. Also I'm almost sure it worked fine few days ago Any ideas?

Try setting the second param to null, and send an options object as the third param with an object named json in the third with a plain JS object inside.

paypal.request.post(PAYMENT_URL, null, {
    json : {
        name:'test',
        price:10
      }
  })

It's not in the documentation, I was having similar issues but dug around in the source code to get it to work.
