Syntax

public abstract class BaseEndpoint : IConfigurationSerializable

Constructors

BaseEndpoint()

Creates a new Base Endpoint.

Declaration

protected BaseEndpoint()

BaseEndpoint(Uri)

Creates a new Base Endpoint.

Declaration

protected BaseEndpoint(Uri endpointUri)

Parameters

Type	Name	Description
System.Uri	endpointUri	Endpoint URI.

Properties

Credentials

Gets the HTTP authentication credentials to be used to access the endpoint.

Declaration

public NetworkCredential Credentials { get; set; }

Property Value

Type	Description
System.Net.NetworkCredential

HttpMode

Gets/Sets the HTTP Mode used for requests.

Declaration

public virtual string HttpMode { get; set; }

Property Value

Type	Description
string

Remarks

This property defaults to the value AUTO. in AUTO mode GET will be used unless the total length of query parameters exceeeds 2048 characters or the query contains non-ASCII characters, and POST will be used for longer queries or where the query contains non-ASCII characters.

Only AUTO, GET and POST are permitted - implementations may override this property if they wish to support more methods.

Proxy

Gets/Sets a Proxy Server to be used.

Declaration

public IWebProxy Proxy { get; set; }

Property Value

Type	Description
System.Net.IWebProxy

ProxyCredentials

Gets/Sets Credentials to be used for Proxy Server.

Declaration

public ICredentials ProxyCredentials { get; set; }

Property Value

Type	Description
System.Net.ICredentials

Timeout

Gets/Sets the HTTP Timeouts used specified in milliseconds.

Declaration

public int Timeout { get; set; }

Property Value

Type	Description
int

Remarks

Defaults to 30 Seconds (i.e. the default value is 30,000).

It is important to understand that this timeout only applies to the HTTP request portions of any operation performed and that the timeout may apply more than once if a POST operation is used since the timeout applies separately to obtaining the request stream to POST the request and obtaining the response stream. Also the timeout does not in any way apply to subsequent work that may be carried out before the operation can return so if you need a hard timeout you should manage that yourself.

When set to a zero/negative value then the standard .Net timeout of 100 seconds will apply, use System.Int32.MaxValue if you want the maximum possible timeout i.e. if you expect to launch extremely long running operations.

Not supported under Silverlight, Windows Phone and Portable Class Library builds.

Uri

Gets the Endpoints URI.

Declaration

public Uri Uri { get; }

Property Value

Type	Description
System.Uri

UseCredentialsForProxy

Controls whether the Credentials set with the SetCredentials() method or the Credentialsare also used for a Proxy (if used).

Declaration

public bool UseCredentialsForProxy { get; set; }

Property Value

Type	Description
System.Boolean

UserAgent

Gets/Sets the user agent string to pass in the request header.

Declaration

public string UserAgent { get; set; }

Property Value

Type	Description
string

Remarks

Defaults to null, which will not set the header.

Methods

ApplyCustomRequestOptions(HttpWebRequest)

Method which may be overridden in derived classes to add any additional custom request options/headers to the request.

Declaration

protected virtual void ApplyCustomRequestOptions(HttpWebRequest httpRequest)

Parameters

Type	Name	Description
System.Net.HttpWebRequest	httpRequest	HTTP Request.

Remarks

This is called at the end of ApplyRequestOptions(HttpWebRequest) so can also be used to override that methods default behaviour.

ApplyRequestOptions(HttpWebRequest)

Applies generic request options (timeout, authorization and proxy server) to a request.

Declaration

protected void ApplyRequestOptions(HttpWebRequest httpRequest)

Parameters

Type	Name	Description
System.Net.HttpWebRequest	httpRequest	HTTP Request.

ClearCredentials()

Clears any in-use credentials so subsequent requests will not use HTTP authentication.

Declaration

public void ClearCredentials()

ClearProxy()

Clears any in-use credentials so subsequent requests will not use a proxy server.

Declaration

public void ClearProxy()

ClearProxyCredentials()

Clears the in-use proxy credentials so subsequent requests still use the proxy server but without credentials.

Declaration

public void ClearProxyCredentials()

SerializeConfiguration(ConfigurationSerializationContext)

Declaration

public virtual void SerializeConfiguration(ConfigurationSerializationContext context)

Parameters
