jQuery美元。使用字符串数组调用Web Api

I am trying to call a .net Web Api method via jquery's $.ajax. When I pass in

我正在尝试通过jquery的$.ajax调用。net Web Api方法。当我通过

var process = "first process", var nameArray = ["first", "second"], var valueArray = ["val1", "val2"]

var process =“first process”，var nameArray = ["first"， "second"]， var valueArray = ["val1"， "val2"]

and then:

然后:

 $.ajax({
url: jsonFeed,
data: {process: process, nameArray: nameArray, valueArray: valueArray},
    etc...

I have a ASP.NET Web Api method:

我有一个ASP。NET Web Api方法:

  public string GetResponseToken(string process, string[] nameArray, string[] valueArray)

When I run everything, I receive an error message:

当我运行一切时，我收到一条错误消息:

"Can't bind multiple parameters ('nameArray' and 'valueArray') to the request's content."

不能将多个参数('nameArray'和'valueArray')绑定到请求的内容。

Does anyone know why this is, or how I can fix it to accept my arrays?

有人知道这是为什么吗?或者我如何修复它以接受数组?

The Web.API parameter/model binder work differently than the MVC one. You need to tell it that you wan't to bind all of your arguments from the query string with the [FromUri] attribute:

网络。API参数/模型绑定器的工作方式与MVC不同。您需要告诉它，您不想将查询字符串中的所有参数与[FromUri]属性绑定:

public string GetResponseToken(
      [FromUri]string process, 
      [FromUri]string[] nameArray, 
      [FromUri]string[] valueArray)
{
    //... 
}

In the long run (e.g the above mentioned approach won't work if you your request type is a POST) you should consider to use a parameter object instead of having multiple arguments.

从长远来看(e。如果您的请求类型是POST，那么上面提到的方法将不起作用)您应该考虑使用参数对象，而不是使用多个参数。

public string GetResponseToken([FromUri]ResponseTokenRequest request)
{
    //...
}

public class ResponseTokenRequest
{
    public string Process { get; set; }
    public string[] NameArray { get; set; }
    public string[] ValueArray { get; set; }
}
