我正在尝试做一个完整的Angularjs网站进行培训。我读过很多关于这个的文章不允许的方法,但是没有找到解决办法。我试图发送一个数据对象到我的服务。AngularJS,REST,C#服务,405 - 不允许Post方法
错误:无法加载资源:服务器与405状态响应(不允许的方法)
这是我AngularJS部分。
var addNews =
{
Title: newsList.newsTitle,
NewsContent: newsList.newsContent,
CreationDate: newsList.newsCreationDate,
CreatedBy: newsList.newsAuthor,
ModificationDate: newsList.newsCreationDate,
ModifiedBy: newsList.newsAuthor
};
var news = JSON.stringify(addNews);
$http({
method: 'POST',
dataType: 'json',
url: 'http://localhost:11672/InfinytecServices.svc/SaveNews',
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json'
},
data: news
});
这里是我的服务部分
[OperationContract]
[WebInvoke(Method = "POST",
UriTemplate = "/SaveNews",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json)]
int SaveNews(News news);
WebConfig正在添加
<?xml version="1.0" encoding="utf-8"?>

而且至少,在CORS
public class CORSEnablingBehavior : BehaviorExtensionElement, IEndpointBehavior
{
public void AddBindingParameters(
ServiceEndpoint endpoint,
BindingParameterCollection bindingParameters){ }
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime) { }
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
endpointDispatcher.DispatchRuntime.MessageInspectors.Add(
new CORSHeaderInjectingMessageInspector()
);
}
public void Validate(ServiceEndpoint endpoint) { }
public override Type BehaviorType { get { return typeof(CORSEnablingBehavior); } }
protected override object CreateBehavior() { return new CORSEnablingBehavior(); }
private class CORSHeaderInjectingMessageInspector : IDispatchMessageInspector
{
public object AfterReceiveRequest(
ref Message request,
IClientChannel channel,
InstanceContext instanceContext)
{
return null;
}
private static IDictionary<string, string> _headersToInject = new Dictionary<string, string>
{
{ "Access-Control-Allow-Origin", "*" },
{ "Access-Control-Request-Method", "POST,GET,PUT,DELETE,OPTIONS" },
{ "Access-Control-Allow-Headers", "X-Requested-With,Content-Type" }
};
public void BeforeSendReply(ref Message reply, object correlationState)
{
var httpHeader = reply.Properties["httpResponse"] as HttpResponseMessageProperty;
foreach (var item in _headersToInject)
httpHeader.Headers.Add(item.Key, item.Value);
}
}
}
你能帮助我吗?
提前,谢谢! :)
您可以发布浏览器网络选项卡的屏幕截图吗?浏览器使用OPTIONS进行两个调用,另一个使用POST方法。当你的服务通过OPTIONS方法接收到请求时,它应该返回CORS信息,并在它到达你的api方法之前结束请求。由于api只接受POST,所以无法处理OPTIONS请求。 –
在帖子中添加,我还添加了控制台选项卡。 Thx :) – Eidan
