【问题描述】:
我正在尝试创建一个完整的 Angularjs 网站进行培训。我已经阅读了很多关于这个Method not allowed的文章,但没有找到解决方案。我正在尝试将数据对象发送到我的服务。
错误:加载资源失败:服务器响应状态为 405(不允许方法)
这是我的 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
});
这是我的服务部分
[OperationContract]
[WebInvoke(Method = "POST",
UriTemplate = "/SaveNews",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json)]
int SaveNews(News news);
WebConfig 即将上线

至少,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);
}
}
}
你能帮帮我吗?
提前谢谢! :)
【问题讨论】:
-
您能否发布您的浏览器网络选项卡的屏幕截图。浏览器进行了两次调用,一次使用 OPTIONS,另一次使用 POST 方法。当您的服务使用 OPTIONS 方法接收请求时,它应该返回 CORS 信息并在请求到达您的 api 方法之前结束请求。由于 api 只接受 POST 它无法处理 OPTIONS 请求。

在帖子中添加,我还添加了控制台选项卡。谢谢 :)
