web-services

问题 I am using methods with the Attribute [WebMethod] in my aspx pages. I don't use any asp.net ajax but jQuery to call these methods and return objects in JSON. This all works fine.

问题 I have been provided RESTful web services to push data into a remote DB of another application. I need to call these services to push data from PostgreSQL DB by sending data in JSON format as GET/POST parameters to the web service.

问题 I have a simple site example.com and an external file link. I want this scenario to be implemented: Once a user visits example.com, a file from an external link is automatically downloaded. Mind that I don't want a user to click some link, but just an immediate file download once the site is visited. Thus <a href="link/to/file" download>Download</a> is not what I need.

I generate a XML with body inside body data correctly for the soap message and look like this: <SERVICE_DISPATCHER_REQUEST xmlns="http://inti.notariado.org/XML" xmlns:ns2="http://ancert.notariado.org/XML/CSN"><ns2:SERVICIO_CONSIGNACION_NOTARIAL><ns2:REQUEST><ns2:CABECERA><ns2:ID_COMUNICACION>2147483647</ns2:ID
