问题 I have a flex client connecting to a web service that needs an authentication token added as a header, named "Identity". An example of the expected message is: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Header> <Identity xmlns="ns">2188dcbe-0325-4c1e-9a77-19110e0ea99f</Identity> <To s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">https://localhost:8001/MyService</To> <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com

问题 This one's killing me. I've read through a lot of Oleg's comments, and through the documentation, but I think I'm overlooking something really simple. I have a jqGrid populated by calling a webmethod that returns JSON. We're good there. I'm using the Navigator for my "Add" button, and using onSelectRow w/ jqGrid.editRow() for my editing. I get the dialog box when clicking the "Add" button, and can fill everything in. However, I get a error Status: 'Internal Server Error'. Error code: 500

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: .NET code to send ZPL to Zebra printers My company has a Eltron 2543 thermal printer. I'm developing an VB.NET application incorporating FedEx web services to print off shipping labels.

Sort of lost here and would love if

问题 Do anyone know how can I write POST method in RESTful web service to upload data using java ? I found that smartupload and commons.upload are just for web page. 回答1: You can use some JAX-RS library, like Apache Wink, so you can write something like this: @Path("/upload") class UploadResource { @POST @Consumes(MediaType.APPLICATION_OCTET_STREAM) public Response upload(byte[] input) { // store input somewhere return Response.ok().build(); } } So you will receieve your file is byte[] . You can

问题 If REST based web services are as simple as GETing and POSTing to a url and parsing the response wht exactly do we need a wsdl? Whats the point. I understand that when using SOAP based services it is used to construct the SOAP requests and responses but dont really see why visual studio provides me with a wsdl when I create a REST based service... 回答1: There is no point in WSDL for REST services created with WCF because WCF supports only WSDL 1.1 (or 1.0) which cannot describe REST seevice.

I also feel this requirement is weird, because in general an App or a web application is used by n number of users so it is difficult to monitor those many API
