.Net webservice读取http头 [英] .Net webservice reading http header
问题描述
我有以下情况：
Android应用程序正在调用我的c＃webservice。在HTTP标题中，将有一个令牌，我必须在每次调用我的web服务时检查以验证调用者的身份。
我想要强调我的webservice不是WCF服务，它的名字以asmx结尾。
我的一个webmethods的代码如下：
I have the following situation:
An android app is calling my c# webservice. In the HTTP header there will be a token which I have to check each time my webservice is called in order to validate the identity of the caller.
I would like to stress that my webservice is not a WCF service, its name ends with asmx.
The code for one of my webmethods looks like this:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<Object> GetContact(string clientNr, int clientId = 0)
{
var contact = new List<Object>();
...code ommited
return contact;
}
我的想法是拨打电话，例如
My idea is to make a call like
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<Object> GetContact(string clientNr, int clientId = 0)
{
If(CheckToken())
{
var contact = new List<Object>();
...code ommited
}
return contact;
}
函数CheckToken将返回True或False。它会从HTTP Header读取令牌，但我该怎么做？
亲切的问候
Jeroen
The function CheckToken would return True or False. It would be reading the token from the HTTP Header, but how do I do that?
Kind regards

推荐答案
您必须创建从soapheader类派生的令牌。
公共类TokenHeader：System.Web.Services。 Protocols.SoapHeader
{
public string tokenNo;
}
in Web服务类使用
公共TokenHeader令牌;
[WebMethod]
[SoapHeader（token，Required = true）]
public string GetToken（）
{
if（checkToken（））
返回token.tokenNo;
else
返回身份验证错误;
}
private bool checkToken（）
{
if（token！= null）
{
i f（token.tokenNo == 100）
返回true;
else
返回false;
}
else
返回false;
}
You will have to create the token derived from soapheader class.
public class TokenHeader : System.Web.Services.Protocols.SoapHeader
{
public string tokenNo;
}
in the web service class use
public TokenHeader token;
[WebMethod]
[SoapHeader("token",Required=true)]
public string GetToken()
{
if (checkToken())
return token.tokenNo;
else
return "Error in authentication";
}
private bool checkToken()
{
if (token!= null)
{
if (token.tokenNo==100)
return true;
else
return false;
}
else
return false;
}
这就是我想出的：
命名空间TestServiceHttpAuthentication
{
公共类AuthenticateRequestHttpModule：IHttpModule
{
私人HttpApplication mHttpApp;
public void Init（HttpApplication httpApp）
{
this.mHttpApp = httpApp;
mHttpApp.AuthenticateRequest + = new EventHandler（OnAuthentication）;
}
void OnAuthentication（对象发送者，EventArgs a）
{
HttpApplication application = （HttpApplication）发件人;
HttpRequest request = application.Context.Request;
// WindowsIdentity identity =（WindowsIdentity）application.Context.User.Identity;
StreamWriter sw = new StreamWriter（request.MapPath（Test.txt），true）;
sw.WriteLine（application.Context.Request.HttpMethod。 ToString（））;
sw.WriteLine（application.Context.Request.Headers.Count.ToString（））;
NameValueCollection coll;
coll = application.Context.Request.Headers;
string [] arr1 = coll.AllKeys;
for（int loop1 = 0; loop1< arr1.length; loop1 ++ ）>
{
sw.WriteLine（arr1 [loop1] .ToString（））;
string [] arr2 = coll.GetValues（arr1 [loop1]）;
for（int loop2 = 0; loop2< arr2.length; loop2 ++）>
{
sw.WriteLine（arr2 [loop2] .ToString（ ））;
}
}
sw.Flush（）;
sw.Close（）;
}
public void Dispose（ ）
{}
}
}
在web.config中：
This is what I came up with:
namespace TestServiceHttpAuthentication
{
public class AuthenticateRequestHttpModule : IHttpModule
{
private HttpApplication mHttpApp;
public void Init(HttpApplication httpApp)
{
this.mHttpApp = httpApp;
mHttpApp.AuthenticateRequest += new EventHandler(OnAuthentication);
}
void OnAuthentication(object sender, EventArgs a)
{
HttpApplication application = (HttpApplication)sender;
HttpRequest request = application.Context.Request;
//WindowsIdentity identity = (WindowsIdentity)application.Context.User.Identity;
StreamWriter sw = new StreamWriter(request.MapPath("Test.txt"), true);
sw.WriteLine(application.Context.Request.HttpMethod.ToString());
sw.WriteLine(application.Context.Request.Headers.Count.ToString());
NameValueCollection coll;
coll=application.Context.Request.Headers;
string[] arr1 = coll.AllKeys;
for(int loop1=0;loop1<arr1.length;loop1++)>
{
sw.WriteLine(arr1[loop1].ToString());
string[] arr2=coll.GetValues(arr1[loop1]);
for(int loop2=0;loop2<arr2.length;loop2++)>
{
sw.WriteLine(arr2[loop2].ToString());
}
}
sw.Flush();
sw.Close();
}
public void Dispose()
{ }
}
}
And in the web.config:
<httpModules>
add name="AuthenticateRequestHttpModule" type="TestServiceHttpAuthentication.AuthenticateRequestHttpModule, TestServiceHttpAuthentication" />
</httpModules>
现在我可以从HTTP标头读取，验证特定键/值的值对。
感谢那些和我一起想过的人。

Now I can read from the HTTP header, validate the values from specific key/value pairs.
Thanks for those who''ve thought with me.
