A web engine URL scheme describes a URL scheme from the web engine's perspective, specifying how URLs of this scheme should be parsed, and which security restrictions should be placed on resources originating from such URLs.
Custom URL schemes must be configured early at application startup, before creating any Qt WebEngine classes. In general this means the schemes need to be configured before a QGuiApplication or QApplication 实例被创建。
Every registered scheme configuration applies globally to all profiles.
int main(int argc, char **argv) { QWebEngineUrlScheme scheme("myscheme"); scheme.setSyntax(QWebEngineUrlScheme::Syntax::HostAndPort); scheme.setDefaultPort(2345); scheme.setFlags(QWebEngineUrlScheme::SecureScheme); QWebEngineUrlScheme::registerScheme(scheme); ... }
To actually make use of the custom URL scheme, a QWebEngineUrlSchemeHandler must be created and registered in a profile.

This enum type specifies security options that should apply to a URL scheme.
| 常量 | 值 | 描述 |
|---|---|---|
QWebEngineUrlScheme::SecureScheme
|
0x1
|
Indicates that the URL scheme is
potentially trustworthy
. This flag should only be applied to URL schemes which ensure data authenticity, confidentiality, and integrity, either through encryption or other means. Examples of secure builtin schemes include
https
(authenticated and encrypted) and
qrc
(local resources only), whereas
http
is an example of an insecure scheme.
|
QWebEngineUrlScheme::LocalScheme
|
0x2
|
Indicates that the URL scheme provides access to local resources. The purpose of this flag is to prevent network content from accessing local resources. Only schemes with the
LocalAccessAllowed
flag may load resources from a scheme with the
Local
flag. The only builtin schemes with this flag are
file
and
qrc
.
|
QWebEngineUrlScheme::LocalAccessAllowed
|
0x4
|
Indicates that content from this scheme should be allowed to load resources from schemes with the
Local
标志。
|
QWebEngineUrlScheme::NoAccessAllowed
|
0x8
|
Indicates that all content from this scheme should be forced to have unique opaque origins: no two resources will have the same origin. |
QWebEngineUrlScheme::ServiceWorkersAllowed
|
0x10
|
Indicates that the Service Workers API should be enabled. |
QWebEngineUrlScheme::ViewSourceAllowed
|
0x20
|
Indicates that the View Source feature should be enabled. |
QWebEngineUrlScheme::ContentSecurityPolicyIgnored
|
0x40
|
Indicates that accesses to this scheme should bypass all Content-Security-Policy checks. |
QWebEngineUrlScheme::CorsEnabled
|
0x80
|
Enables cross-origin resource sharing (CORS) for this scheme. This flag is required in order to, for example, use the scheme with the 抓取 API , or to deliver CSS fonts to a different origin. The appropriate CORS headers are generated automatically by the QWebEngineUrlRequestJob class. (Added in Qt 5.14) |
Flags 类型是 typedef 对于 QFlags <Flag>。它存储 Flag 值的 OR 组合。
This enum type defines special values for defaultPort .
| 常量 | 值 | 描述 |
|---|---|---|
QWebEngineUrlScheme::PortUnspecified
|
-1
|
Indicates that the URL scheme does not have a port element. |
This enum type lists types of URL syntax.
To apply the same-origin policy to a custom URL scheme,
WebEngine
must be able to compute the origin (host and port combination) of a URL. The
Host...
options indicate that the URL scheme conforms to the standard URL syntax (like
http
) and automatically enable the same-origin policy. The
路径
option indicates that the URL scheme uses a non-standard syntax and that the same-origin policy cannot be applied.
| 常量 | 值 | 描述 |
|---|---|---|
QWebEngineUrlScheme::Syntax::HostPortAndUserInformation
|
0
|
The authority component of a URL of this type has all of the standard elements: host, port, user name, and password. A URL without a port will use the defaultPort (which must not be PortUnspecified ). |
QWebEngineUrlScheme::Syntax::HostAndPort
|
1
|
The authority component of a URL of this type has only the host and port elements. A URL without a port will use the defaultPort (which must not be PortUnspecified ). |
QWebEngineUrlScheme::Syntax::Host
|
2
|
The authority component of a URL of this type has only the host part and no port. The defaultPort must be set to PortUnspecified . |
QWebEngineUrlScheme::Syntax::Path
|
3
|
A URL of this type has no authority component at all. Everything after scheme name and separator character (:) will be preserved as is without validation or canonicalization. All URLs of such a scheme will be considered as having the same origin (unless the
NoAccessAllowed
flag is used).

void
QWebEngineUrlScheme::
registerScheme
(const
QWebEngineUrlScheme
&
scheme
)
注册 scheme with the web engine's URL parser and security model.
It is recommended that all custom URL schemes are first registered with this function at application startup, even if the default options are to be used.
警告： This function must be called early at application startup, before creating any WebEngine classes. Late calls will be ignored.
