Javascript 正在尝试获取JQuery帖子以与WCF通信,但不接受JSON数据
我正在使用以下JQuery\JavaScript代码与WCF 4 REST服务通信Javascript 正在尝试获取JQuery帖子以与WCF通信,但不接受JSON数据,javascript,ajax,wcf,jquery,Javascript,Ajax,Wcf,Jquery,我正在使用以下JQuery\JavaScript代码与WCF 4 REST服务通信 <script> var serviceUrl = "http://services.xiine.com/Xiine/Live/AccountService/rest/json/Login"; var userInfo = { "IsNotEncrypted":true, "Password":null, "
<script>
var serviceUrl = "http://services.xiine.com/Xiine/Live/AccountService/rest/json/Login";
var userInfo = {
"IsNotEncrypted":true,
"Password":null,
"UserName":null
};
var loginSuccess = function(data, textStatus, jqXHR){
console.log("yay");
};
var loginError = function(){
console.log("oh no");
};
$.post(serviceUrl , userInfo, loginSuccess);
$.post(serviceUrl , loginSuccess);
</script>
与我传递用户数据时相反,此时它会给出POST 400(错误请求)错误
我确信这与JSON对象userInfo的构建或解释方式有关,如果有帮助的话,我可以发布Fiddler 2或WireShark转储。让我知道
我真的无法更改服务的WCF端,所以希望在我这方面我能做些什么来实现这一点
谢谢

我得到了更多的信息。。。显然,问题在于服务器响应时出现以下错误:
服务器在处理请求时遇到错误。异常消息为“传入消息>具有意外消息格式“Raw”。操作所需的消息格式为“Xml”>“Json”。这可能是因为尚未在绑定上配置WebContentTypeMapper。有关详细信息,请参阅WebContentTypeMapper的>文档。“。有关详细信息,请参阅服务器日志。>异常堆栈跟踪是:
在System.ServiceModel.Dispatcher.DemultiplexingDispatchMessageFormatter.DeserializeRequest(消息消息,对象[]参数)在System.ServiceModel.Dispatcher.UriTemplateDispatchFormatter.DeserializeRequest(消息,对象[]参数)在System.ServiceModel.Dispatcher.CompositeDispatchFormatter.DeserializerRequest在System.ServiceModel.Dispatcher.DispatcherOperationRuntime.System.ServiceModel.Dispatcher.DispatcherOperationRuntime.InvokeBegin(MessageRpc&rpc)在System.ServiceModel.Dispatcher.ImmutableDispatcherRuntime.ProcessMessage5(MessageRpc&rpc)上的(消息消息消息消息,对象[]参数)位于System.ServiceModel.Dispatcher.ImmutableDispatcheRuntime.ProcessMessage41(MessageRpc&rpc)的System.ServiceModel.Dispatcher.MessageRpc.Process(布尔等操作上下文集)
因此,我想我需要弄清楚如何通过JQuery.post()方法使对象作为JSON对象通过连接
更多信息——再一次
好的……这里没有app.config或web.config
这里是我能得到的关于合同和代码的信息
[ServiceContract]
public interface IAccount
{
[OperationContract]
bool Login(UserInformation user);
}
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class AccountService : IAccount
{
public bool Login(UserInformation user)
{
//stuff...
}
}
[DataContract]
public class UserInformation
{
[DataMember(IsRequired = true)]
public string UserName;
[DataMember(IsRequired = true)]
public string Password;
[DataMember(IsRequired = true)]
public bool IsNotEncrypted;
}
public interface IUserInformation
{
UserInformation UserInformation { get; set; }
}
在服务的接口中,您需要具有OperationalContract属性,并且在该属性中,您需要设置RequestFormat
[OperationContract, WebInvoke(UriTemplate = "/runGenericMethodJSON", Method = "POST",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest)]
所以,我找到了我问题的答案 有人试图通过提到JSON.stringify()方法来为我指明正确的方向,但我花了一点努力才能正确地实现它 最后,我使用WireShark嗅出http请求,查看实际发送和接收的内容,并观察到不仅需要对数据进行加密,还需要指定内容类型 这是最后的代码
// This is the URL that is used for the service.
var serviceUrl = "http://services.xiine.com/Xiine/Live/AccountService/rest/json/Login";
// This is the JSON object passed to the service
var userInfo = {
"UserName": null,
"Password": null,
"IsNotEncrypted": true
};
// $.ajax is the longhand ajax call in JQuery
$.ajax({
type: "POST",
url: serviceUrl,
contentType: "application/json; charset=utf-8",
// Stringify the userInfo to send a string representation of the JSON Object
data: JSON.stringify(userInfo),
dataType: "json",
success: function(msg) {
console.log(msg);
}});
请发布您的WCF服务配置。不幸的是,我没有访问权限…我已尝试实施您的建议,但似乎不起作用…

RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest)]
