Javascript 将数据发送到ServiceStack RESTful服务,获取';访问被拒绝';
我用ServiceStack构建了一个RESTful服务,它将数据发送到数据库。我在本地测试过,效果很好。当我将它部署到服务器并运行相同的代码(jQuery$.ajax调用)时,我得到一个“访问被拒绝”错误。我在ServiceStack配置中使用插件as设置了CORS。在ajax调用中,我还将crossDomain设置为true。我想不出还能做些什么来让它工作,老实说,我也不确定这个错误会被抛出到哪里。我已经浏览了Javascript,但它甚至没有到达ajax调用的“failure”块,在此之前会抛出错误。。。我正在使用IE9进行测试,如果相关的话 知道会发生什么吗 以下是我的ServiceStack POST方法:Javascript 将数据发送到ServiceStack RESTful服务,获取';访问被拒绝';,javascript,jquery,ajax,rest,

public CitationResponse Post(Citation citation)
{
var response = new CitationResponse { Accepted = false };
if (string.IsNullOrEmpty(citation.ReportNumber))
{
response.Accepted = false;
response.Message = "No data sent to service. Please enter data in first.";
return response;
}
try
{
response.ActivityId = Repository.CreateCitation(citation.ReportNumber, citation.ReportNumber_Prefix, citation.ViolationDateTime, citation.AgencyId, citation.Status);
response.Accepted = true;
}
catch (Exception ex)
{
response.Accepted = false;
response.Message = ex.Message;
response.RmsException = ex;
}
return response;
}
下面是调用web服务的Javascript函数:
SendCitationToDb: function(citation, callback) {
$.ajax({
type: "POST",
url: Citations.ServiceUrl + "/citations",
data: JSON.stringify(citation),
crossDomain: true,
contentType: "application/json",
dataType: "json",
success: function (data) {
if (!data.Accepted) {
Citations.ShowMessage('Citation not added', 'Citation not added to database. Error was: ' + data.Message, 'error');
} else {
citation.ActivityId = data.ActivityId;
callback(data);
}
},
failure: function(errMsg) {
Citations.ShowMessage('Citation not added', 'Citation not added to database. Error was: ' + errMsg.Message, 'error');
}
});
}
谢谢你的帮助
更新:
我刚刚在Chrome 29上运行了相同的应用程序,我发现了以下错误(为了安全起见,替换了真实的URL):
现在,如果我在Chrome中运行相同的服务调用,我将从ServiceStack获得有效响应。以下是响应标题:

现在我不知道该怎么办。我什么都试过了,但还是会犯同样的错误。使用Chrome中的REST控制台,这些方法仍然工作得很好,这有点令人恼火,因为我无法让它们在网页上调用它们。我几乎准备好用WCF重新编写整个过程,但我真的很想让ServiceStack版本正常工作,因为我知道它在本地工作!如果有人有任何其他建议我可以尝试,我将非常感谢你的帮助
更新:
有关详细信息,请参见底部的注释。我必须从IIS中的HTTP标题选项卡中删除标题。我不确定我什么时候把它们放进去,但对于其他可能面临同样问题的人,这里是IIS中选项卡的屏幕截图:
在我之前的工作中,我和你有同样的问题 您可以阅读mythz和的非常有用的答案 我在AppHost中使用的代码
using System.Web;
using ServiceStack.WebHost.Endpoints.Extensions; // for httpExtensions methods
// => after v.3.9.60, =>using ServiceStack;

谢谢你的回复。在过去的几天里,我尝试了你的建议,以及其他一些推荐的修复方法,但仍然得到了最初问题中提到的相同错误。IE显示访问被拒绝,Chrome显示我的主叫域“不被访问控制允许来源所允许。*”完全不明白这为什么不起作用。我让另一个开发者看了看,我们在周五和今天都花了几个小时,但仍然没有运气。它在本地工作,部署时不工作。如果我直接在REST控制台中进行服务调用,它们就可以工作,但不是通过jQueryAjax调用。Eddie,上面的代码在生产环境中工作。作为一个单独的示例,您尝试过吗?除非我在复制粘贴上犯了错误,否则它应该可以正常工作。今天早上我花时间用您的代码构建了一个测试项目,将它部署到同一台服务器上,结果成功了。所以我开始并排比较项目,看看有什么不同。代码中的所有内容看起来都一样。最后,我远程访问了服务器,打开了这两个站点的属性,发现“HTTP头”选项卡中的“自定义HTTP头”列出了相同的头。我把它们拿走了,罪恶
