详细描述#

此类是 Qt 网络 API 的接口类型，用于或使用此类头部。

允许的字段名和值字符#

HTTP 头部由名称和值组成。在设置这些时，QHttpHeaders 会验证名称和值只包含 HTTP RFCs 允许的字符。有关详细信息，请参阅 RFC 9110 的第 5.1 和 5.5 章节。

广泛地说，这意味着

name 必须由可见的 ASCII 字符组成，且不能为空

value 可以由任意字节组成，只要遵循头部和使用情况特定的编码规则。《code class="docutils literal notranslate">value 可以是空的

此外，value 在历史上可能包含开头或结尾的空白字符，在处理此类值时必须忽略这些空白字符。此类的设置器会自动删除此类空白字符。

值的组合#

大多数 HTTP 头部值可以通过单个逗号 ',' 进行组合，并且语义意义得到保留。例如，这两个应该是语义上相似的

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

然而，有一个值得注意的例外：Set-Cookie。由于这一点，以及由于可能的自定义使用情况，QHttpHeaders 不会自动组合值。

class WellKnownHeader#

根据 IANA 注册表的已知头部列表。

__init__(other)#

参数：: other – QHttpHeaders

创建 other 的副本。

__init__()

创建一个新的 QHttpHeaders 对象。

append(name, value)#

参数：

name – str
value – str

返回类型：:

bool

追加一个名为 name 且值为 value 的头信息项，并返回 true 表示成功。

另请参阅

WellKnownHeader, QAnyStringView) Allowed field name and value characters

append(name, value)

参数：

size()

combinedValue(name)#

参数：: name – str
返回类型：:: QByteArray

返回头信息 name 的值构成的逗号分隔字符串。如果不存在名为 name 的头信息，则返回一个空的 QByteArray。

注意

以这种方式访问“Set-Cookie”头部的值可能不会按预期工作。在HTTP RFC中，这被视为一个显著的例外，因为其值不能以这种方式合并。请首选使用values()方法。

另请参阅

values(QAnyStringView)

combinedValue(name)

参数：: name – WellKnownHeader
返回类型：:: QByteArray

此函数重载了combinedValue(QAnyStringView)。

contains(name)#

参数：: name – str
返回类型：:: bool

返回头是否包含具有name的头。

另请参阅

WellKnownHeader)

contains(name)

参数：: name – WellKnownHeader
返回类型：:: bool

此函数重载了has(QAnyStringView)。

static fromListOfPairs(headers)#

参数：: headers – std.pair QByteArray, QByteArray 的列表
返回类型：:: QHttpHeaders

创建一个新的 QHttpHeaders 对象，该对象包含 headers。

另请参阅

允许的字段名和值字符

static fromMultiHash(headers)#

参数：: headers – QMultiHashQByteArray, QByteArray
返回类型：:: QHttpHeaders

创建一个新的 QHttpHeaders 对象，该对象包含 headers。

另请参阅

允许的字段名和值字符

static fromMultiMap(headers)#

参数：: headers – QMultiMapQByteArray, QByteArray
返回类型：:: QHttpHeaders

创建一个新的 QHttpHeaders 对象，该对象包含 headers。

另请参阅

允许的字段名和值字符

insert(i, name, value)#

参数：

i – int
name – str
value – str

返回类型：:

bool

在索引 i 处插入一个包含 name 和 value 的头条目。索引必须是有效的（见 size()）。返回插入是否成功。

另请参阅

append() WellKnownHeader, QAnyStringView) size() Allowed field name and value characters

insert(i, name, value)

参数：

i – int
name – WellKnownHeader
value – str

返回类型：:

bool

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

isEmpty()#

返回类型：:: bool

如果头部大小为 0，则返回 true；否则返回 false。

另请参阅

size()

nameAt(i)#

参数：: i – int
返回类型：:: QLatin1String

返回索引 i 位置的头部名称。索引 i 必须有效（参见 size()）。

头部名称不区分大小写，返回的名称均为小写。

另请参阅

size() valueAt()

removeAll(name)#

参数：: name – str

移除名为 name 的头部。

另请参阅

removeAt() WellKnownHeader)

removeAll(name)

参数：: name – WellKnownHeader

replace(i, name, newValue)#

参数：

i – int
name – str
newValue – str

返回类型：:

bool

替换索引为 i 的标题条目，使用 name 和 newValue。索引必须是有效的（参见 size()）。返回替换是否成功。

另请参阅

append() WellKnownHeader, QAnyStringView) size() Allowed field name and value characters

replace(i, name, newValue)

参数：

i – int
name – WellKnownHeader
newValue – str

返回类型：:

bool

此函数覆盖了 replace(qsizetype, QAnyStringView, QAnyStringView)。

reserve(size)#

参数：: size – int

尝试为至少 size 个标题条目分配内存。

如果您提前知道将有多少个标题条目，可以调用此函数以防止重新分配和内存碎片化。

size()#

返回类型：:: int

返回标题条目的数量。

swap(other)#

参数：: other – QHttpHeaders

将此 QHttpHeaders 与 other 交换。此函数非常快速且从不失败。
