c#webservice返回错误 [英] c# webservice return error

问题描述

我需要这方面的帮助.请对我温柔点，我还不是专家.

I need some help regarding this. Please be gentle with me, Im not an expert - yet.

问题是我试图通过 JSON 将数据从客户端(浏览器)发送到服务器(网络服务).当我在 Fiddler 中观看 POST 数据时，我可以看到我发送的 JSON.这是有效的(已测试).但是我的网络服务(当我手动测试然后我得到返回 OK)返回以下内容:{Message":处理请求时出错."，StackTrace":"，ExceptionType":""}"

The thing is that Im trying to send data from a client (browser) to the server (webservice) via JSON. When I watch the POST data in Fiddler, I can see the JSON I send. This is valid (tested). But my webservice, (when I manually test then I get a return OK), returns the following: "{"Message":"There was an error processing the request.","StackTrace":"","ExceptionType":""}"

不幸的是，它仅供内部使用，所以我无法为您发布网络服务.

Unfortunately its only for internal use so I can't publish the webservice for you.

有人可以向我解释一下有什么问题吗?

推荐答案

尝试格式化发送的数据以匹配 Web 服务方法

Try formatting the data sent to match the web service method

<script>
    var markers = {param1:1, param2:"test"}; //<-- format the model

    $.ajax({
        type: "POST",
        url: "http://xxx.xxx.xxx.xxx/site/util.asmx/CreateMarkers",
        // The key needs to match your method's input parameter (case-sensitive).
        data: JSON.stringify(markers),  //<-- just send the markers
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (data) { alert(data); },
        failure: function (errMsg) {
            alert(errMsg);
        }
   });
</script>
