Detailed Description

Represents an HTTP response header first line. The first line includes 2 parameters: status code (e.g 200 OK, 404 Not Found, etc.), and HTTP version (e.g HTTP/1.1). These 2 parameters are included in this class, and the user can retrieve or set them. This class cannot be instantiated by users, it's created inside HttpResponseLayer and user can get a pointer to an instance of it. The "get" methods of this class will retrieve the actual data of the HTTP response and the "set" methods will change the packet data. Since HTTP is a textual protocol, most fields aren't of fixed size and this also applies to the first line parameters. So most "set" methods of this class need in most cases to shorten or extend the data in HttpResponseLayer. These methods will return a false value if this action failed

Member Function Documentation

int pcpp::HttpResponseFirstLine::getSize ( )
inline
Returns
The size in bytes of the HTTP first line
HttpResponseLayer::HttpResponseStatusCode pcpp::HttpResponseFirstLine::getStatusCode ( )
inline
Returns
The status code as HttpResponseLayer::HttpResponseStatusCode enum
int pcpp::HttpResponseFirstLine::getStatusCodeAsInt ( )
Returns
The status code number as integer (e.g 200, 404, etc.)
std::string pcpp::HttpResponseFirstLine::getStatusCodeString ( )
Returns
The status code message (e.g "OK", "Not Found", etc.)
HttpVersion pcpp::HttpResponseFirstLine::getVersion ( )
inline
Returns
The HTTP version
bool pcpp::HttpResponseFirstLine::isComplete ( )
inline

As explained in HttpResponseLayer, an HTTP header can spread over more than 1 packet, so when looking at a single packet the header can be partial. Same goes for the first line - it can spread over more than 1 packet. This method returns an indication whether the first line is partial

Returns
False if the first line is partial, true if it's complete
static HttpResponseLayer::HttpResponseStatusCode pcpp::HttpResponseFirstLine::parseStatusCode ( char *  data,
size_t  dataLen 
)
static

A static method for parsing the HTTP status code out of raw data

Parameters
[in]dataThe raw data
[in]dataLenThe raw data length
Returns
The parsed HTTP status code as enum
bool pcpp::HttpResponseFirstLine::setStatusCode ( HttpResponseLayer::HttpResponseStatusCode  newStatusCode,
std::string  statusCodeString = "" 
)

Set the status code

Parameters
[in]newStatusCodeThe new status code to set
[in]statusCodeStringAn optional parameter: set a non-default status code message (e.g "Bla Bla" instead of "Not Found"). If this parameter isn't supplied or supplied as empty string (""), the default message for the status code will be set
void pcpp::HttpResponseFirstLine::setVersion ( HttpVersion  newVersion)

Set the HTTP version. This method doesn't return a value since all supported HTTP versions are of the same size (HTTP/0.9, HTTP/1.0, HTTP/1.1)

Parameters
[in]newVersionThe HTTP version to set
