The QHttpHeader class contains header information for HTTP.
In most cases you should use the more specialized derivatives of this class, QHttpResponseHeader and QHttpRequestHeader , rather than directly using QHttpHeader .
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 value () 和 setValue ()，如
header.setValue("content-type", "text/html"); QString contentType = header.value("content-type");
Some fields are so common that getters and setters are provided for them as a convenient alternative to using value () 和 setValue ()，如 contentLength () 和 contentType (), setContentLength () 和 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.

Constructs an empty HTTP header.
構造副本為 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 "\r\n" delimited lines; each of these lines should have the format key, colon, space, value.
