字符串数组后对Web API方法 [英] Post array of strings to web API method

问题描述

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..."); }
    });

这是铬合金网头：

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

Request Method:POST

表格数据视图的URL连接codeD

Form Dataview URL encoded

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

这是我的WebAPI控制器的方法：

public HttpResponseMessage UpdateStatusToDelete(string[] data)

结果：

当我调试，在UpdateStatusToDelete数据参数返回 {字符串[0]} ，而不是数据：一 数据：乙 数据：C 数据：D

when I debug, the data parameter in UpdateStatusToDelete returns {string[0]} instead of data:a data:b data:c data:d

我是什么做错了吗？任何帮助真的AP preciated。

What am I doing wrong? Any help is really appreciated.

推荐答案

有关通过简单的类型，数据发布必须采取一个名字值对的名称部分为空字符串的形式。所以，你需要做的Ajax调用就像这样：

For passing simply types, the data to post must take the form of a name value pair with the name portion being an empty string. So you need to make the Ajax call like so:

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

此外，您的Web API的行动，将其标注为瓦特/ [FromBody]属性。是这样的：

Additionally, on your Web API action, annotate it w/ the [FromBody] attribute. Something like:

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

这是应该做的伎俩。
