问题 I'm working on an application which makes a web service request using the HttpClient API to a third party service over which I have no control. The service seems to respond to requests with an ETag HTTP header containing an invalid value according to the HTTP specification (the value is not enclosed in quotation marks). This causes the HttpClient to fail with a System.FormatException . In this case I am not interested in the ETag header and would like to be able to ignore the invalid value.

问题 We have a vendor supplied solution that requires a username and password to utilize their APIs exposed as a web service. They are to be included in the actual xml of the call. We obviously don't like that. Does anyone know of any product, system, whatever, that we can have calling systems authenticate to with token based security, which would then inject the username password and forward the request in a secure zone accessible by the product but not the outside callers. And of course return

问题 When exactly does the Application_End fire in the case of a WebService ?? I read (Application_End global.asax) that the Application_End is called everytime the application is unloaded. Does this mean after every call to a method in a web service ? I have a piece of code that I need fired only once on the first call to the IIS, and again after the last call to the IIS (and between recycles), and I can't have it being fired upon every WebService request and response... 回答1: Application_End is

问题 I have recently created a web service that uses a static method in Java to obtain a list of items from the database. The web service works perfectly and returns JSON back to the caller. However, it works only once. If you try to refresh or make a new request, I get a EntityManagerFactory is closed error. Here's how the Web Service class looks like: public class WebService extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws

问题 I have to call 5 APIs in sequence after generating the token. i am using below API to generate token . POST https://idcs-xxxx.identity.c9dev2.oc9qadev.com/oauth2/v1/token I will send username and password to get token in above API. Once token will be received I will have to use the same token to call below 5 APIs in sequence. I will use output of one API and filter it and pick some values as an input to next API . all the rest endpoint will change based on the input value of previous API
