ISchemeRegistrarAddCustomScheme Method |
Version 71.0.0
Register a custom scheme. This method should not be called for the built-in
HTTP, HTTPS, FILE, FTP, ABOUT and DATA schemes.
If
isStandard is true the scheme will be treated as a standard scheme.
Standard schemes are subject to URL canonicalization and parsing rules as
defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1 available
at http://www.ietf.org/rfc/rfc1738.txt
In particular, the syntax for standard scheme URLs must be of the form:
[scheme]://[username]:[password]@[host]:[port]/[url-path]
Standard scheme URLs must have a host component that is a fully qualified
domain name as defined in Section 3.5 of RFC 1034 [13] and Section 2.1 of
RFC 1123. These URLs will be canonicalized to "scheme://host/path" in the
simplest case and "scheme://username:password@host:port/path" in the most
explicit case. For example, "scheme:host/path" and "scheme:///host/path"
will both be canonicalized to "scheme://host/path". The origin of a
standard scheme URL is the combination of scheme, host and port (i.e.,
"scheme://host:port" in the most explicit case).
For non-standard scheme URLs only the "scheme:" component is parsed and
canonicalized. The remainder of the URL will be passed to the handler
as-is. For example, "scheme:///some%20text" will remain the same.
Non-standard scheme URLs cannot be used as a target for form submission.
This function may be called on any thread. It should only be called once
per unique
schemeName value. If
schemeName is already registered or
if an error occurs this method will return false.

Parameters
- schemeName
- Type: SystemString
scheme name, e.g. custom - isStandard
- Type: SystemBoolean
is this a standard scheme, see above for details - isLocal
- Type: SystemBoolean
If true the scheme will be treated with the same security
rules as those applied to "file" URLs. Normal pages cannot link to or
access local URLs. Also, by default, local URLs can only perform
XMLHttpRequest calls to the same URL (origin + path) that originated the
request. To allow XMLHttpRequest calls from a local URL to other URLs with
the same origin set the CefSettings.file_access_from_file_urls_allowed
value to true. To allow XMLHttpRequest calls from a local URL to all
origins set the CefSettings.UniversalAccessFromFileUrlsAllowed value
to true. - isDisplayIsolated
- Type: SystemBoolean
If true the scheme can only be displayed from
other content hosted with the same scheme. For example, pages in other
origins cannot create iframes or hyperlinks to URLs with the scheme. For
schemes that must be accessible from other schemes set this value to false,
set isCorsEnabled to true, and use CORS "Access-Control-Allow-Origin"
headers to further restrict access. - isSecure
- Type: SystemBoolean
If true the scheme will be treated with the same security rules as those applied to "https" URLs.
For example, loading this scheme from other secure schemes will not trigger mixed content warnings. - isCorsEnabled
- Type: SystemBoolean
If true the scheme can be sent CORS requests. This value should be true in most cases where isStandard is true. - isCspBypassing
- Type: SystemBoolean
If true the scheme can bypass Content-Security-Policy
(CSP) checks. This value should be false in most cases where isStandard is true.
Return Value
