将字符串数组发布到Web API方法

Question

这是我的客户端ajax调用:

    var list = ["a", "b", "c", "d"];

    var jsonText = { data: list };

    $.ajax({
        type: "POST",
        url: "/api/scheduledItemPriceStatus/updateStatusToDelete",
        data: jsonText,
        dataType: "json",
        traditional: true,
        success: function() { alert("it worked!"); },
        failure: function() { alert("not working..."); }
    });

这是chrome网络标题:

Request URL:http://localhost:2538/api/scheduledItemPriceStatus/updateStatusToDelete

Request Method:POST

X-Requested-With:XMLHttpRequest

表格Dataview URL编码

data:a
data:b
data:c
data:d

这是我的webapi控制器方法:

public HttpResponseMessage UpdateStatusToDelete(string[] data)

结果:

当我调试时,UpdateStatusToDelete中的data参数返回{string[0]}而不是数据:a data:b data:c data:d

我究竟做错了什么？任何帮助都非常感谢.

Answer 1

对于传递简单类型,要发布的数据必须采用名称值对的形式,名称部分为空字符串.所以你需要像这样进行Ajax调用:

$.ajax({
  type: "POST",
  url: "/api/values",
  data: { "": list },
  dataType: "json",
  success: function() { alert("it worked!"); },
  failure: function() { alert("not working..."); }
});

此外,在Web API操作上,使用[FromBody]属性对其进行注释.就像是:

public void Post([FromBody]string[] values)

这应该够了吧.

使用var jsonText = { data: JSON.stringify(list)}
