ServiceStack请求正文

问题描述 投票：4回答：1

我正在尝试在servicestack和ormlite中编写我的第一个REST服务。还不错。

我设法编写了显示所有记录，基于和ID的记录并删除基于ID的记录的代码。

现在，我要开始添加和编辑记录，而对于如何从调用的请求正文中获取数据感到困惑。

我正在做

POST: http://localhost:7571/equipment/create/123

带有请求主体

[{"eMCo":"1","equipment":"DP112","location":"Field","manufacturer":"","model":"","modelYr":"2013","vinNumber":"","description":"Trevor","status":"A","attachToEquip":"BR118","licensePlateNo":""}]

但是在我的服务中，我无法确定如何使用此功能访问请求正文数据：

public object Post(EMEMTrev request)
    {
        var dbFactory = new OrmLiteConnectionFactory("Data Source=(local);Initial Catalog=Kent;Integrated Security=True", SqlServerDialect.Provider);
        using (IDbConnection db = dbFactory.OpenDbConnection())
        {
            //base.Request.FormData[""]
            db.Insert(request);
        }
        return null;
    }

这里是完整的代码...如果您可以指出任何错误，请执行！

您的问题与JSON数据和DTO之间的大小写差异有关。映射区分大小写。因为大小写匹配，所以填充了equipment参数，但其余属性没有。

您可以通过将此行添加到AppHost配置中来解决此问题。

JsConfig.EmitCamelCaseNames = true;

这将序列化程序设置为将JSON数据中的location映射到DTO中的Location 和其他属性，并在序列化时处理回转换。

因此，您可以访问请求参数上的属性，而不必通过原始数据。

您的服务看起来不错。我无法立即看到任何问题，我认为问题可能在于您如何调用服务。

以下这些方法将有助于调试问题。我建议您尝试使用此简单的HTML页面呼叫客户端，并查看是否填充了必填字段。

[创建文件，将其命名为test.html并将其放在ServiceStack服务程序集的bin文件夹中，然后导航到服务路径http://localhost:7571/test.html。

<!doctype html>
<html>
    <head>
        <title>Test</title>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script>
            function send()
            {
                // Send data to the service
                $.ajax({
                    type: "POST",
                    url: "/equipment/create/DP112",
                    contentType: "application/json",
                    data: JSON.stringify({
                        eMCo: "1",
                        equipment: "DP112",
                        location: "Field",
                        manufacturer: "",
                        model: "",
                        modelYr: "2013",
                        vinNumber: "",
                        description: "Trevor",
                        status: "A",
                        attachToEquip: "BR118",
                        licensePlateNo: ""
                    })
                }).done(function(result){

                });
            }
        </script>
</head>
<body>
    <button onclick="send()">Send Request</button>
</body>
</html>

此html文件应提供格式正确的请求。

也可以考虑通过添加此行到AppHost配置中来添加请求记录器。然后转到http://localhost:7571/requestlogs。 See here了解更多信息。

Plugins.Add(new RequestLogsFeature());

请求ContentType：

如果未在客户端请求上设置正确的内容类型，则ServiceStack不会将值填充到请求中。将请求上的contentType设置为application/json即可。
