详细描述¶

该类是一个接口类型，用于使用或消费此类标头的Qt网络API。

允许的字段名称和值字符¶

HTTP头由名称和值组成。在设置这些时，QHttpHeaders会验证名称和值，以确保它们只包含HTTP RFCs允许的字符。有关详细信息，请参阅RFC 9110第5.1和5.5章。

总的来说，这意味着：

name 必须由可见的ASCII字符组成，且不能为空

value 可以包含任意字节，只要遵守头部和特定用例的编码规则。value 可以为空

此类的设置器会自动移除value中的任何前导或尾随空格，因为在value处理过程中必须忽略它们。

组合值¶

大多数HTTP头值可以用单个逗号','加上可选的空格组合，语义保持不变。例如，这两个在语义上应该是相似的：

// Values as separate header entries
myheadername: myheadervalue1
myheadername: myheadervalue2
// Combined value
myheadername: myheadervalue1, myheadervalue2

然而，这条规则有一个显著的例外：Set-Cookie。由于这一点以及自定义用例的可能性，QHttpHeaders 不会自动合并这些值。

性能¶

大多数 QHttpHeaders 函数都提供了 WellKnownHeader 和 QAnyStringView 的重载。从内存使用和计算的角度来看，建议使用 WellKnownHeader 的重载。

class WellKnownHeader¶

根据IANA注册表的知名头列表。

__init__()¶

创建一个新的QHttpHeaders对象。

__init__(other)

Parameters:: 其他 – QHttpHeaders

创建 other 的副本。

append(name, value)¶

Parameters:

name – str
value – str

Return type:

布尔

使用name和value附加一个头条目，并在成功时返回true。

另请参阅

WellKnownHeader, QAnyStringView) 允许的字段名称和值字符

append(name, value)

Parameters:

name – WellKnownHeader
value – str

Return type:

布尔

此函数重载了 append(QAnyStringView, QAnyStringView) 。

clear()¶

清除所有头条目。

另请参阅

size()

combinedValue(name)¶

Parameters:: name – str
Return type:: QByteArray

返回头部name的值，以逗号组合的字符串形式。如果带有name的头部不存在，则返回一个null的QByteArray。

注意

以这种方式访问‘Set-Cookie’头的值可能无法按预期工作。这是HTTP RFC中的一个显著例外，因为它的值不能以这种方式组合。建议使用values()代替。

另请参阅

values(QAnyStringView)

combinedValue(name)

Parameters:: 名称 – WellKnownHeader
Return type:: QByteArray

此函数重载了 combinedValue(QAnyStringView) 。

contains(name)¶

Parameters:: name – str
Return type:: 布尔

返回头部是否包含名为 name 的头部。

另请参阅

WellKnownHeader)

contains(name)

Parameters:: 名称 – WellKnownHeader
Return type:: 布尔

此函数重载了has(QAnyStringView)。

static fromListOfPairs(headers)¶

Parameters:: headers – .std.pairQByteArray,QByteArray 的列表
Return type:: QHttpHeaders

创建一个新的QHttpHeaders对象，并用headers填充。

另请参阅

允许的字段名称和值字符

static fromMultiHash(headers)¶

Parameters:: headers – .QMultiHashQByteArray,QByteArray
Return type:: QHttpHeaders

创建一个新的QHttpHeaders对象，并用headers填充。

另请参阅

允许的字段名称和值字符

static fromMultiMap(headers)¶

Parameters:: headers – .QMultiMapQByteArray,QByteArray
Return type:: QHttpHeaders

创建一个新的QHttpHeaders对象，并用headers填充。

另请参阅

Allowed field name and value characters

insert(i, name, value)¶

Parameters:

i – 整数
name – str
value – str

Return type:

布尔

在索引 i 处插入一个头条目，包含 name 和 value。索引必须有效（参见 size()）。返回插入是否成功。

另请参阅

append() WellKnownHeader, QAnyStringView) size() 允许的字段名称和值字符

insert(i, name, value)

Parameters:

i – 整数
name – WellKnownHeader
value – str

Return type:

布尔

此函数重载了 insert(qsizetype, QAnyStringView, QAnyStringView) 。

isEmpty()¶

Return type:: 布尔

如果头部的大小为0，则返回true；否则返回false。

另请参阅

size()

nameAt(i)¶

Parameters:: i – 整数
Return type:: QLatin1String

返回索引 i 处的标题名称。索引 i 必须有效（参见 size() ）。

头部名称是大小写不敏感的，返回的名称是小写的。

另请参阅

size() valueAt()

removeAll(name)¶

Parameters:: name – str

移除头部 name。

另请参阅

removeAt() WellKnownHeader)

removeAll(name)

Parameters:: 名称 – WellKnownHeader

此函数重载了 removeAll(QAnyStringView) 。

removeAt(i)¶

Parameters:: i – 整数

移除索引 i 处的标题。索引 i 必须有效（参见 size() ）。

另请参阅

WellKnownHeader) removeAll(QAnyStringView) size()

replace(i, name, newValue)¶

Parameters:

i – 整数
name – str
newValue – 字符串

Return type:

布尔

用name和newValue替换索引i处的头条目。索引必须有效（参见size()）。返回替换是否成功。

另请参阅

append() WellKnownHeader, QAnyStringView) size() 允许的字段名称和值字符

replace(i, name, newValue)

Parameters:

i – 整数
name – WellKnownHeader
newValue – str

Return type:

布尔

此函数重载了 replace(qsizetype, QAnyStringView, QAnyStringView) 。

replaceOrAppend(name, newValue)¶

Parameters:

name – str
newValue – 字符串

Return type:

布尔

此函数重载了 replaceOrAppend(WellKnownHeader, QAnyStringView)。

replaceOrAppend(name, newValue)

Parameters:

name – WellKnownHeader
newValue – 字符串

Return type:

布尔

如果 QHttpHeaders 已经包含 name，则用 newValue 替换其值，并删除可能的额外 name 条目。如果 name 不存在，则追加一个新条目。如果成功，返回 true。

此函数是一个便捷方法，用于设置唯一的name : newValue 头信息。对于大多数头信息，相对顺序并不重要，这允许在存在现有条目时重复使用。

另请参阅

replaceOrAppend(QAnyStringView, QAnyStringView)

reserve(size)¶

Parameters:: size – int

尝试为至少 size 个头条目分配内存。

如果你提前知道会有多少个头部条目，你可以调用这个函数来防止重新分配和内存碎片化。

size()¶

Return type:: 整数

返回头条目的数量。

swap(other)¶

Parameters:: 其他 – QHttpHeaders

将此 QHttpHeaders 与 other 交换。此函数非常快且永远不会失败。

toListOfPairs()¶

Return type:: std.pairQByteArray的列表，QByteArray

返回头部条目作为（名称，值）对的列表。头部名称不区分大小写，返回的名称是小写的。

toMultiHash()¶

Return type:: .QMultiHashQByteArray,QByteArray

返回头部条目作为从名称到值的哈希。头部名称不区分大小写，返回的名称是小写的。

toMultiMap()¶

Return type:: .QMultiMapQByteArray,QByteArray

返回头部条目作为从名称到值的映射。头部名称不区分大小写，返回的名称是小写的。

value(name[, defaultValue={}])¶

Parameters:

name – str
defaultValue – QByteArrayView

Return type:

QByteArrayView

返回（第一个）标头name的值，如果不存在则返回defaultValue。

另请参阅
