I'm doing a POST to a service using Postman Chrome Extension , and I get the expected response. But, when I do the same POST request using $http , all goes to hell. I get a : Request header field Engaged-Auth-Token is not allowed by Access-Control-Allow-Headers Engaged-Auth-Token being a header.

阅读更多关于 How to receive POST request in an AngularJS page?

We made a AngularJS app where user opens a URL (xyz.com/booking) fills the forms and then selects some items for purchase. After that user clicks on BUY button and leaves the site for the payment gateway site. On successful payment, Payment Gateway sends back the user by sending a POST request on a Callback URL(xyz.com/booking-success). Now problem is that my corresponding Angular Page that I configured for that Callback URL is not opening. I configured xyz.com/booking-success page in RouteProvider, but that seems not to be working. However, if I open the page xyz.com/booking-success directly

API requires POST arguments in a query string?

阅读更多关于 API requires POST arguments in a query string?

问题 I'm playing with the Twitter API and noticed something funny- For updates, they require POST methods but expect the arguments in the query string. (See for example, the status/update call in their developer console here.) Obviously this is technically possible, but why would anyone do it like that? Don't POST arguments belong in the body? 回答1: Either option is just as valid. My favourite example for using parameters in the URL for a POST is an application that sets waypoints on a map. e.g.

How to deal with timed out POST requests

阅读更多关于 How to deal with timed out POST requests

In a RESTful SOA, suppose I issue a POST request via AJAX but I don't get a response before the request times out. Further suppose a re-submission of the request would be harmful. POST is not idempotent. For example, maybe I am posting a bank transfer of money. If I don't get a response, I don't know if the server processed the request. What is the best practice to deal with this, assuming I have control over the client-side and the services side? My initial thought is to include a nonce (i.e. a pseudo-id; some sort of unique identifier) with each POST request; e.g. perhaps a value in the If
