我正在使用 JQuery 和 Ajax 与 ASP.Net Web 服务进行交互。这是Jquery代码:
$.jrpc = function(url, id, method, params, success, error) {
var request = $.json_stringify({
'jsonrpc': '2.0', 'method': method,
'params': params, 'id': id});
return $.ajax({
url: url,
data: "json=" + encodeURIComponent(request),
success: success,
error: error,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
async: true,
cache: false,
//timeout: 1,
type: 'POST'});
};
这是网络服务代码:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class Access : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string EntryMethod(string json)
{
Requests d = JsonConvert.DeserializeObject<Requests>(json);
Response resp = new Response();
resp.jsonrpc = d.jsonrpc;
resp.result = "Got the call!";
resp.id = d.id;
resp.error = null;
JavaScriptSerializer response = new JavaScriptSerializer();
string r = response.Serialize(resp);
return r;
}
}
我收到此错误:
[AJAX] 错误 - 服务器响应为:{"Message":"Invalid JSON primitive: json.","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject()\r\n at System.Web .Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n 在 System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(字符串输入,Int32 depthLimit,JavaScriptSerializer 序列化程序)\r\n 在 System.Web.Script.Serialization .JavaScriptSerializer.Deserialize(JavaScriptSerializer 序列化程序,字符串输入,类型类型,Int32 depthLimit)\r\n 在 System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](字符串输入)\r\n 在 System.Web.Script .Services.RestHandler.GetRawParamsFromPostRequest(HttpContext 上下文,JavaScriptSerializer 序列化程序)\r\n 在 System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n 在 System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)" "ExceptionType":"System.ArgumentException"}
使用 ASP.Net webservice 测试页面,这里是我的标题和请求字符串: Cache-Control: private, max-age=0 Date: Wed, 03 Oct 2012 19:47:16 GMT Content-Length: 149 Content-Type:文本/xml;charset=utf-8 服务器:ASP.NET 开发服务器/10.0.0.0 X-AspNet-Version:4.0.30319 连接:关闭
json=%7B%22jsonrpc%22%3A%222.0%22%2C%22method%22%3A%22test%22%2C%22params%22%3A%5B%5D%2C%22id%22%3A1%7D
这是我的 Ajax 调用的标头/请求字符串,它不起作用: Cache-Control: private Date: Wed, 03 Oct 2012 19:47:09 GMT Content-Length: 1062 Content-Type: application/json; charset=utf-8 jsonerror: true 服务器:ASP.NET 开发服务器/10.0.0.0 X-AspNet-Version:4.0.30319 连接:关闭

关于我为什么会收到此错误的任何想法?我试过用谷歌搜索它,但没有一个结果真的对我有帮助。
编辑:
如果我使用:数据:“{'jsonrpc':'2.0','method':'test','params':[],'id':1}”,
我收到此错误:[AJAX] 错误 - 服务器响应为:{“消息”:“无效的 Web 服务调用,参数缺失值:\u0027json\u0027。”,“StackTrace”:“在 System.Web.Script.Services .WebServiceMethodData.CallMethod(对象目标,IDictionary 2 parameters)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary
