通过 Jquery ajax 将 javascript 对象传递给 webservice

发布于 2024-10-09 13:46:13 字数 1859 浏览 1 评论 0原文

我有一个返回对象的 Web 服务

[WebMethod]
    public List<User> ContractorApprovals()

我也有一个接受对象的 Web 服务

[WebMethod]
    public bool SaveContractor(Object u)

当我通过 Jquery 进行 Web 服务调用时：

function ServiceCall(method, parameters, onSucess, onFailure) {
    var parms = "{" + (($.isArray(parameters)) ? parameters.join(',') : parameters) + "}"; // to json
    $.ajax({
        type: "POST",
        url: "services/"+method,
        data: parms,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            if (typeof onSucess == 'function' || typeof onSucess == 'object')
                onSucess(msg.d);
        },
            error: function(msg, err) {
            $("#dialog-error").dialog('open');}
});

我可以很好地调用第一个。我的 onSucess 函数传递了一个 JavaScript 对象，其结构与我在服务上的 User 对象完全相同。

但是，我现在无法将对象返回到服务器。

我接受对象作为服务器端的参数，所以我无法想象那里存在问题。所以我认为客户端的参数出了问题，但我不确定是什么......

我正在做一些事情，

ServiceCall("AuthorizationManagerWorkManagement.asmx/ContractorApprovals",
      "",
      function(data,args){$("#div").data('user',data[0])},
      null)

然后

ServiceCall("AuthorizationManagerWorkManagement.asmx/SaveContractor",
      JSON.stringify({u: $("#div").data("user")}) //dont work $("#div").data('user'), //These also do not work: "{'u': ' + $("#div").data("user") + '}", NOR JSON.stringify({u: userObject})
      function(data,args){(alert(data)},
      null)

我知道第一个服务调用有效，我可以获取数据。第二个是导致执行“onFailure”方法而不是“OnSuccess”。

有什么想法吗？

更新：

我修改了最后一个要使用的代码块： JSON.stringify({u: $("#div").data("user")})

我现在得到 传递了无效的对象中，应为成员名称。 (1):

但我不知道这意味着什么...谷歌已经发现了很多这样的错误，但没有像我这样的问题...

原文

I have a webservice that returns an object

[WebMethod]
    public List<User> ContractorApprovals()

I also have a webservice that accepcts an object

[WebMethod]
    public bool SaveContractor(Object u)

When I make my webservice calls via Jquery:

function ServiceCall(method, parameters, onSucess, onFailure) {
    var parms = "{" + (($.isArray(parameters)) ? parameters.join(',') : parameters) + "}"; // to json
    $.ajax({
        type: "POST",
        url: "services/"+method,
        data: parms,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            if (typeof onSucess == 'function' || typeof onSucess == 'object')
                onSucess(msg.d);
        },
            error: function(msg, err) {
            $("#dialog-error").dialog('open');}
});

I can call the first one just fine. My onSucess function gets passed a javascript object exactly structured like my User object on the service.

However, I am now having trouble getting the object back to the server.

I'm accepting Object as a parameter on the server side so I can't inagine there is an issue there. So I'm thinking something is wrong with the parms on the client side but i'm not sure what...

I am doing something to the effect

ServiceCall("AuthorizationManagerWorkManagement.asmx/ContractorApprovals",
      "",
      function(data,args){$("#div").data('user',data[0])},
      null)

then

ServiceCall("AuthorizationManagerWorkManagement.asmx/SaveContractor",
      JSON.stringify({u: $("#div").data("user")}) //dont work $("#div").data('user'), //These also do not work: "{'u': ' + $("#div").data("user") + '}", NOR JSON.stringify({u: userObject})
      function(data,args){(alert(data)},
      null)

I know the first service call works, I can get the data. The second one is causing the "onFailure" method to execute rather then "OnSuccess".

Any ideas?

UPDATE:

I chaed my last code block to use : JSON.stringify({u: $("#div").data("user")})

I now get Invalid object passed in, member name expected. (1):

But I have no idea what the means... Google has turned up plenty of that error, but no problem like mine...
