WCF服务，带有参数的下载文件，根据GET请求发送数据

Question

jQuery has support for sending data with a GET request:

jQuery.get( url [, data ] [, success(data, textStatus, jqXHR) ] [, dataType ] )

Is it possible to write a WCF service that supports receiving data on a GET request?

An example is much appreciated.

UPDATE: Url length exceeds the limit for IE8 and IE8 is a requirement. I need to pass a lot of parameters, basically a big JSON. What I did to workaround this is to make a POST request,store the parameters on the server side, then set window.location to the service location the invoke a GET request that will download my file.But, I want to avoid the POST request and storing the file on server side because I'm in a distributed system and I have a lot of issues with this.

Answer 1

Sure you can:

[OperationContract]
[WebInvoke(
    Method = "GET",
    UriTemplate = "SomeUrl?param1={param1}&param2={param2}"
)]
string SomeOperation(string param1, string param2);

And then:

$.get('SomeService.svc/SomeUrl?param1=SomeValue&param2=AnotherValue', function(response) {
    console.log(response);
});

Or:

$.get('SomeService.svc/SomeUrl', {param1: 'SomeValue', param2: 'AnotherValue'}, function(response) {
    console.log(response);
});

It is possible. Here link for more info - How to: Choose between HTTP POST and HTTP GET requests for ASP.NET AJAX Endpoints

But REST services are more suitable for AJAX and calling from JS. When it is going about new service, you can use ASP.NET Web API. A lot of tutorials about it here
