Url Delphi DLL Reference Documentation
Url
Current Version: 11.0.0
Provides an object representation of a URL and easy access to the parts of the URL.
Create/Dispose
var myObject: HCkUrl; begin myObject := CkUrl_Create(); // ... CkUrl_Dispose(myObject); end;
Creates an instance of the HCkUrl object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.
Objects created by calling CkUrl_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.
Properties
DebugLogFilePath
procedure CkUrl_putDebugLogFilePath(objHandle: HCkUrl; newPropVal: PWideChar); stdcall;
function CkUrl__debugLogFilePath(objHandle: HCkUrl): PWideChar; stdcall;
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
See the notes about PWideChar memory ownership and validity.
Frag
function CkUrl__frag(objHandle: HCkUrl): PWideChar; stdcall;
Contains any text following a fragment marker (#) in the URL, excluding the fragment marker. Given the URI http://www.contoso.com/index.htm#main, the fragment is "main".
See the notes about PWideChar memory ownership and validity.
topHost
function CkUrl__host(objHandle: HCkUrl): PWideChar; stdcall;
The DNS host name or IP address part of the URL. For example, if the URL is "http://www.contoso.com:8080/", the Host is "www.contoso.com". If the URL is "https://192.168.1.124/test.html", the Host is "192.168.1.124".
See the notes about PWideChar memory ownership and validity.
HostType
function CkUrl__hostType(objHandle: HCkUrl): PWideChar; stdcall;
The type of the host name specified in the URL. Possible values are:
- "dns": The host name is a domain name system (DNS) style host name.
- "ipv4": The host name is an Internet Protocol (IP) version 4 host address.
- "ipv6": The host name is an Internet Protocol (IP) version 6 host address.
See the notes about PWideChar memory ownership and validity.
topLastErrorHtml
function CkUrl__lastErrorHtml(objHandle: HCkUrl): PWideChar; stdcall;
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
See the notes about PWideChar memory ownership and validity.
topLastErrorText
function CkUrl__lastErrorText(objHandle: HCkUrl): PWideChar; stdcall;
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
See the notes about PWideChar memory ownership and validity.
LastErrorXml
function CkUrl__lastErrorXml(objHandle: HCkUrl): PWideChar; stdcall;
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
See the notes about PWideChar memory ownership and validity.
topLastMethodSuccess
procedure CkUrl_putLastMethodSuccess(objHandle: HCkUrl; newPropVal: wordbool); stdcall;
Indicates the success or failure of the most recent method call: True
means success, False
means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
Login
function CkUrl__login(objHandle: HCkUrl): PWideChar; stdcall;
If the URL contains a login and password, this is the login part. For example, if the URL is "http://user:password@www.contoso.com/index.htm ", then the login is "user".
See the notes about PWideChar memory ownership and validity.
topPassword
function CkUrl__password(objHandle: HCkUrl): PWideChar; stdcall;
If the URL contains a login and password, this is the password part. For example, if the URL is "http://user:password@www.contoso.com/index.htm ", then the password is "password".
See the notes about PWideChar memory ownership and validity.
topPath
function CkUrl__path(objHandle: HCkUrl): PWideChar; stdcall;
The path (and params) part of the URL, excluding the query and fragment. If the URL is: "http://www.amazon.com/gp/product/1476752842/ref=s9_psimh_gw_p14_d0_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1", then the path is "/gp/product/1476752842/ref=s9_psimh_gw_p14_d0_i3".
See the notes about PWideChar memory ownership and validity.
PathWithQueryParams
function CkUrl__pathWithQueryParams(objHandle: HCkUrl): PWideChar; stdcall;
The path (and params) part of the URL, including the query params, but excluding the fragment. If the URL is: "http://www.amazon.com/gp/product/1476752842/ref=s9_psimh_gw_p14_d0_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1", then then this property returns "/gp/product/1476752842/ref=s9_psimh_gw_p14_d0_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1".
See the notes about PWideChar memory ownership and validity.
topPort
The port number of the URL.
For example, if the URL is "http://www.contoso.com:8080/", the port number is 8080.
If the URL is "https://192.168.1.124/test.html", the port number is the default 80.
If the URL is "https://www.amazon.com/", the port number is the default SSL/TLS port 443.
Query
function CkUrl__query(objHandle: HCkUrl): PWideChar; stdcall;
The query part of the URL, excluding the fragment. If the URL is: "http://www.amazon.com/gp/product/1476752842/ref=s9_psimh_gw_p14_d0_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1#frag", then the query is "pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1".
See the notes about PWideChar memory ownership and validity.
topSsl
True
if the URL indicates SSL/TLS, otherwise false. A URL beginning with "https://" indicates SSL/TLS.
VerboseLogging
procedure CkUrl_putVerboseLogging(objHandle: HCkUrl; newPropVal: wordbool); stdcall;
If set to True
, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False
. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version
function CkUrl__version(objHandle: HCkUrl): PWideChar; stdcall;
Version of the component/library, such as "10.1.0"
See the notes about PWideChar memory ownership and validity.
Methods

url: PWideChar): wordbool; stdcall;
Parses a full URL. After parsing, the various parts of the URL are available iin the properties.
Returns True for success, False for failure.
