Url C 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
HCkUrl instance = CkUrl_Create(); // ... CkUrl_Dispose(instance);
Creates an instance of the HCkUrl object and returns a handle ("void *" 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. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkUrl_Dispose.
Properties
DebugLogFilePath
void CkUrl_putDebugLogFilePath(HCkUrl cHandle, const char *newVal);
const char *CkUrl_debugLogFilePath(HCkUrl cHandle);
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.
Frag
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".
topHost
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".
HostType
const char *CkUrl_hostType(HCkUrl cHandle);
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.
LastErrorHtml
const char *CkUrl_lastErrorHtml(HCkUrl cHandle);
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.
topLastErrorText
const char *CkUrl_lastErrorText(HCkUrl cHandle);
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.
LastErrorXml
const char *CkUrl_lastErrorXml(HCkUrl cHandle);
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.
topLastMethodSuccess
void CkUrl_putLastMethodSuccess(HCkUrl cHandle, BOOL newVal);
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
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".
topPassword
const char *CkUrl_password(HCkUrl cHandle);
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".
topPath
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".
PathWithQueryParams
const char *CkUrl_pathWithQueryParams(HCkUrl cHandle);
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".
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
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".
topSsl
TRUE if the URL indicates SSL/TLS, otherwise false. A URL beginning with "https://" indicates SSL/TLS.
Utf8
void CkUrl_putUtf8(HCkUrl cHandle, BOOL newVal);
When set to TRUE, all const char * arguments and return values are interpreted as UTF-8 strings. When set to FALSE, they are interpreted as ANSI strings.
In Chilkat v11.0.0 and later, the default value is TRUE. Before v11.0.0, it was FALSE.
VerboseLogging
void CkUrl_putVerboseLogging(HCkUrl cHandle, BOOL newVal);
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.
