Web 引擎 Profile (配置文件) 包含设置、脚本、持久性 Cookie 策略及属于 Profile 由所有 Web 引擎页面共享的拜访链接列表。
Information about visited links is stored together with persistent cookies and other persistent data in a storage determined by the storageName property. Persistent data is stored in a subdirectory determined by the persistentStoragePath property and the cache in a subdirectory determined by the cachePath property. The httpCacheType property describes the type of the cache: in-memory or on-disk . If only the storageName property is set, the other values are generated automatically based on it. If you specify any of the values manually, you should do it before creating any pages that belong to the profile.
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 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

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
|

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 .
