Read the HTTP response from the file ut.txt and parse it to get the status code, headers and body.
The code is written in C++11 and well tested on Linux.
make
g++ -std=c++11 -Wall -c -o obj/HttpResponseParser.o HttpResponseParser.cpp
g++ -std=c++11 -Wall -c -o obj/main.o main.cpp
g++ -std=c++11 -Wall -o bin/httpparser obj/HttpResponseParser.o obj/main.o
./bin/httpparser
HTTP Version: 1.0
Status: 200
Number of valid headers: 4
Number of invalid headers: 0
HTTP Version: 1.1
Status: 302
Number of valid headers: 3
Number of invalid headers: 1
HTTP Version: 2.0
Status: 404
Number of valid headers: 3
Number of invalid headers: 2
Invalid HTTP response: Invalid status line
Invalid HTTP response: Invalid status line
But if you want to test it on Windows, you need to modify the code a little bit.
Because
For Windows, the line separator is "\r\n"
But for Linux, the line separator is "\n"
The code needs to be modified to run on Windows.
size_t statusLinePosEnd = message.find("\n");should be changed to
size_t statusLinePosEnd = message.find("\r\n");
