C# - 如何将 JSON 数据的 Post 数组发送和读取到 WCF RESTful 服务

Question

我的担忧：

1. 我下面的代码是否正确？用于发送的输入。

2. 我尝试使用 SOAPUI 和 POST MAN 进行本地调试，我的函数被命中但输入为空 - 所以我想知道 - 如何发送带有 JSON 数据的 http post 请求？

我正在尝试的网址： http://localhost:49240/TranslationService.svc/DVRDatalist

类型：JSON（应用程序/json） 原始数据：

{"DVRMigration":"[{“ProgramID”:”1111”,”ServiceID”:”1111”,”ChannelNo”:”11”,”TimeSlot”:”1111”},{“ProgramID”:”2222”,”ServiceID”:”2222”,”ChannelNo”:”22”,”TimeSlot”:”2222”},{“ProgramID”:”3333”,”ServiceID”:”3333”,”ChannelNo”:”33”,”TimeSlot”:”3333”},{“ProgramID”:”4444”,”ServiceID”:”4444”,”ChannelNo”:”44”,”TimeSlot”:”4444”}]"}

1. 我需要以下输入的示例代码，该输入被保存并拆分，以便我可以执行我的数据库操作，例如：

   {“ProgramID”:”1111”,”ServiceID”:”1111”,”ChannelNo”:”11”,”TimeSlot”:”1111”}

   并形成最终列表并以 json 格式返回响应

=====================

以下是将发送到 Web 服务的示例输入：

[输入] => JSON 数据

{“DVR Migration”:[{“ProgramID”:”1111”,”ServiceID”:”1111”,”ChannelNo”:”11”,”TimeSlot”:”1111”},{“ProgramID”:”2222”,”ServiceID”:”2222”,”ChannelNo”:”22”,”TimeSlot”:”2222”},{“ProgramID”:”3333”,”ServiceID”:”3333”,”ChannelNo”:”33”,”TimeSlot”:”3333”},{“ProgramID”:”4444”,”ServiceID”:”4444”,”ChannelNo”:”44”,”TimeSlot”:”4444”}]}

以下是我应该从 Web 服务收到的示例输出：

[输出] => JSON 数据

{"DVR Migration”:[{"ChannelNo”:"11","GuideStart":"00","ProgramID”:"1111","PvrID":"111","SeriesID":"1001","ServiceID":"1234","TableID":"11","Title":"ABCD","UpdateFlag":"False”},{"ChannelNo”:"22","GuideStart":"00","ProgramID”:"2222","PvrID":"111","SeriesID":"1001","ServiceID":"1234","TableID":"11","Title":"ABCD","UpdateFlag":"False”},{"ChannelNo”:"33","GuideStart":"00","ProgramID”:"3333","PvrID":"111","SeriesID":"1001","ServiceID":"1234","TableID":"11","Title":"ABCD","UpdateFlag":"False”},{"ChannelNo”:"44","GuideStart":"00","ProgramID”:"4444","PvrID":"111","SeriesID":"1001","ServiceID":"1234","TableID":"11","Title":"ABCD","UpdateFlag":"False”}]}

        DataSet dsdvrdata = dvr.Getdvrdata(pgrmId, svcid, cn, ts, pvrid, tid);
        datalist.ServiceID = dsdvrdata.Tables[0].Rows[0]["ServiceID"].ToString();
        datalist.ProgramID = dsdvrdata.Tables[0].Rows[0]["ProgramID"].ToString();
        datalist.ChannelNo = dsdvrdata.Tables[0].Rows[0]["ChannelNo"].ToString();

        datalist.PvrID = pvrid;
        datalist.TableID = tid;

        response.Add(datalist);
    }
    return response;
}

    [DataMember(Order = 6)]
    public string GuideStart { get; set; }

    [DataMember(Order = 7)]
    public string SeriesID { get; set; }

    [DataMember(Order = 8)]
    public string PvrID { get; set; }

    [DataMember(Order = 9)]
    public string TableID { get; set; }

    #endregion
}

Answer 1

首先，您应该使用[DataContract] 属性装饰您想要的请求/响应类（此处为DataList 类用于响应）。

查看您的代码，您的操作方法需要一个 Migration 对象，而您希望传递一个 DVR Migration 对象。在这种情况下，您应该尝试将 Action 方法参数更改为 DVRMigration，或者您应该将 Migration 对象从 JSON 请求传递到此操作方法。 MVC 模型绑定通过将传入请求数据对象与 Action 参数绑定来工作。它会检查这些名称和属性的兼容性。

然后，您可以创建一个名为 DVRMigration 的 Javascript 对象并初始化其属性并将其发送到控制器，即

var input = { DvrMigration: { ServiceID: 1, ProgramID: 123 and so on} };
$.ajax({
    type: "POST",
    url: "http://localhost:49240/TranslationService.svc/DVRDatalist",
    contentType: "application/json",
    data: JSON.stringify(input),
    success: function (result) {
        alert("POST result: " + JSON.stringify(result));
    }
});
