The QQuickWebEngineProfile class provides a web engine profile shared by multiple pages.
A web engine profile contains properties and functionality shared by a group of web engine pages.
Information about visited links is stored together with persistent cookies and other persistent data in a storage described by the persistentStoragePath 特性。
Profiles can be used to isolate pages from each other. A typical use case is a dedicated off-the-record profile 对于 隐私浏览 mode. An off-the-record profile forces cookies, the HTTP cache, and other normally persistent data to be stored only in memory. The offTheRecord property holds whether a profile is off-the-record.
The default profile can be accessed by defaultProfile (). It is a built-in profile that all web pages not specifically created with another profile belong to.
A WebEngineProfile instance can be created and accessed from C++ through the QQuickWebEngineProfile class, which exposes further functionality in C++. This allows Qt Quick applications to intercept URL requests ( QQuickWebEngineProfile::setRequestInterceptor ), or register custom URL schemes ( QQuickWebEngineProfile::installUrlSchemeHandler ).
Spellchecking HTML form fields can be enabled per profile by setting the spellCheckEnabled property and the current languages used for spellchecking can be set by using the spellCheckLanguages 特性。
此枚举描述 HTTP 缓存类型：
| 常量 | 值 | 描述 |
|---|---|---|
QQuickWebEngineProfile::MemoryHttpCache
|
0
|
Use an in-memory cache. This is the only setting possible if
off-the-record
is set or no cache path is available.
|
QQuickWebEngineProfile::DiskHttpCache
|
1
|
Use a disk cache. This is the default. |
QQuickWebEngineProfile::NoCache
|
2
|
禁用内存和磁盘缓存。(在 Qt 5.7 添加) |
此枚举描述 Cookie 持久性策略：
| 常量 | 值 | 描述 |
|---|---|---|
QQuickWebEngineProfile::NoPersistentCookies
|
0
|
Both session and persistent cookies are stored in memory. This is the only setting possible if
off-the-record
is set or no persistent data path is available.
|
QQuickWebEngineProfile::AllowPersistentCookies
|
1
|
Cookies marked persistent are saved to and restored from disk, whereas session cookies are only stored to disk for crash recovery. This is the default setting. |
QQuickWebEngineProfile::ForcePersistentCookies
|
2
|
会话和持久 Cookie 均保存到磁盘并从中还原。 |
The path to the location where the profile's caches are stored, in particular the HTTP cache.
By default, the caches are stored below QStandardPaths::writableLocation ( QStandardPaths::CacheLocation ) in a directory named using storageName .

访问函数：
| QString | httpAcceptLanguage () const |
| void | setHttpAcceptLanguage (const QString & httpAcceptLanguage ) |
通知程序信号：
| void | httpAcceptLanguageChanged () |
The maximum size of the HTTP cache. If
0
, the size will be controlled automatically by
QtWebEngine
。默认值为
0
.
访问函数：
| int | httpCacheMaximumSize () const |
| void | setHttpCacheMaximumSize (int maxSize ) |
通知程序信号：
