Question

我的担忧：

我的下面的代码是否正确？正在发送的输入。
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 - 如何使用JSON数据发送http post请求？

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

类型：JSON（application / 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”}]"}

我需要保存输入的以下输入的示例代码，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”}

并形成一个最终列表并在json

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

以下是将发送到Web服务的Sample输入：

[INPUT] =＆gt; 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 Service收到的示例输出：

[OUTPUT] =＆gt; 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”}]}

首先，你应该用[DataContract]属性装饰你想要的请求/响应类（这里的DataList类用于响应）。

查看代码，您的操作方法需要一个Migration对象，并且您希望传递一个DVR Migration对象。在这种情况下，您应尝试将Action方法参数更改为DVRMigration，或者应将Migration对象从JSON请求传递给此操作方法。 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));
    }
});
