继承者： QHttpRequestHeader , QHttpResponseHeader
PySide.QtNetwork.QHttpHeader class contains header information for HTTP.
In most cases you should use the more specialized derivatives of this class, PySide.QtNetwork.QHttpResponseHeader and PySide.QtNetwork.QHttpRequestHeader , rather than directly using PySide.QtNetwork.QHttpHeader .
PySide.QtNetwork.QHttpHeader provides the HTTP header fields. A HTTP header field consists of a name followed by a colon, a single space, and the field value. (See RFC 1945.) Field names are case-insensitive. A typical header field looks like this:
content-type: text/html
In the API the header field name is called the “key” and the content is called the “value”. You can get and set a header field's value by using its key with PySide.QtNetwork.QHttpHeader.value() and PySide.QtNetwork.QHttpHeader.setValue() ，如
header.setValue("content-type", "text/html")
contentType = header.value("content-type")
Some fields are so common that getters and setters are provided for them as a convenient alternative to using PySide.QtNetwork.QHttpHeader.value() and PySide.QtNetwork.QHttpHeader.setValue() ，如 PySide.QtNetwork.QHttpHeader.contentLength() and PySide.QtNetwork.QHttpHeader.contentType() , PySide.QtNetwork.QHttpHeader.setContentLength() and PySide.QtNetwork.QHttpHeader.setContentType() .
Each header key has a single value associated with it. If you set the value for a key which already exists the previous value will be discarded.
| 参数： |
|
|---|
Constructs an empty HTTP header.
构造副本为 header .
Constructs a HTTP header for str .
This constructor parses the string str for header fields and adds this information. The str should consist of one or more “rn” delimited lines; each of these lines should have the format key, colon, space, value.
| 参数： |
|
|---|
Adds a new entry with the key and value .
| 参数： | key – unicode |
|---|---|
| 返回类型： | 字符串列表 |
Returns all the entries with the given key . If no entry has this key , an empty string list is returned.
| 返回类型： | PySide.QtCore.uint |
|---|
Returns the value of the special HTTP header field content-length .
| 返回类型： | unicode |
|---|
Returns the value of the special HTTP header field content-type .
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the header has an entry for the special HTTP header field content-length ；否则返回 false。
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the header has an entry for the special HTTP header field content-type ；否则返回 false。
| 参数： | key – unicode |
|---|---|
| 返回类型： | PySide.QtCore.bool |
Returns true if the HTTP header has an entry with the given key ；否则返回 false。
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if the HTTP header is valid; otherwise returns false.
A PySide.QtNetwork.QHttpHeader is invalid if it was created by parsing a malformed string.
| 返回类型： | 字符串列表 |
|---|
Returns a list of the keys in the HTTP header.
| 返回类型： | PySide.QtCore.int |
|---|
Returns the major protocol-version of the HTTP header.
| 返回类型： | PySide.QtCore.int |
|---|
Returns the minor protocol-version of the HTTP header.
| 参数： | str – unicode |
|---|---|
| 返回类型： | PySide.QtCore.bool |
Parses the HTTP header string str for header fields and adds the keys/values it finds. If the string is not parsed successfully the PySide.QtNetwork.QHttpHeader becomes invalid .
返回 true 若 str was successfully parsed; otherwise returns false.
| 参数： |
|
|---|---|
| 返回类型： |
PySide.QtCore.bool |
Parses the single HTTP header line line which has the format key, colon, space, value, and adds key/value to the headers. The linenumber is number . Returns true if the line was successfully parsed and the key/value added; otherwise returns false.
| 参数： | key – unicode |
|---|
Removes all the entries with the key key from the HTTP header.
| 参数： | key – unicode |
|---|
Removes the entry with the key key from the HTTP header.
| 参数： | len – PySide.QtCore.int |
|---|
Sets the value of the special HTTP header field content-length to len .
| 参数： | type – unicode |
|---|
Sets the value of the special HTTP header field content-type to type .
| 参数： | arg__1 – PySide.QtCore.bool |
|---|
| 参数： |
|
|---|
Sets the value of the entry with the key to value .
If no entry with key exists, a new entry with the given key and value is created. If an entry with the key already exists, the first value is discarded and replaced with the given value .
| 参数： | values – |
|---|
| 返回类型： | unicode |
|---|
Returns a string representation of the HTTP header.
The string is suitable for use by the constructor that takes a PySide.QtCore.QString . It consists of lines with the format: key, colon, space, value, “rn”.
| 参数： | key – unicode |
|---|---|
| 返回类型： | unicode |
Returns the first value for the entry with the given key . If no entry has this key , an empty string is returned.
| 返回类型： |
|---|
Returns all the entries in the header.
