Introduction<\/h2>\n\n\n\n

In this part I will show how to create a CGI. With C\/C++ and\/or with Python.
The C\/C++ projects need to be compiled with the same Eclipse configuration as used for the download programs an the SLI programs, see the installation section in: 
https:\/\/github.com\/fischertechnik\/txt_demo_c_download\/blob\/master\/README.md<\/a> orhttps:\/\/github.com\/fischertechnik\/txt_demo_ROBOPro_SLI\/blob\/master\/README.md<\/a><\/p>\n\n\n\n

Startpoint<\/h2>\n\n\n\n

We have already setup a Civetweb server as we have shown in de post “Using TXT CivetWeb server as general web server (part 1A)”<\/p>\n\n\n\n

<\/p>\n\n\n\n

First expriment<\/h2>\n\n\n\n

Add some files to the document_root. And discover the CGI-script with Python or a pre-compiled C\/C++ CGI-script. <\/p>\n\n\n\n

Example of a simple C\/C++ script<\/h4>\n\n\n\n

filenaam: cpptest.cgi, in \/var\/www, don’t forget to adjust the file attributes.<\/p>\n\n\n\n

This file needs to be compiled with the same Eclipse configuration as used for the download programs an the SLI programs, see the installation section in: https:\/\/github.com\/fischertechnik\/txt_demo_c_download\/blob\/master\/README.md<\/a><\/p>\n\n\n\n

Compiles the main.cpp to TxtCgiTest01.cgi

Example of a simple Python script<\/h2>\n\n\n\n
filenaam: pytest.cgi, in \/var\/www, don’t forget to adjust the file attributes.<\/p>\n\n\n\n
This example make use of the already pre-installed FtRoboPy. It is also possible to use the fischertechnik C\/C+ libraries directly from a C\/C++ CGI-script. <\/p>\n\n\n\n
module#!\/usr\/bin\/python3\n# Import modules for CGI handling\nimport cgi, cgitb\nimport ftrobopy\nimport sys\nprint ("Content-type:text\/html\\r\\n\\r\\n")\nprint ('<html>')\nprint ('<head>')\nprint ('<title>Hello Word - First CGI Program<\/title>')\nprint ('<\/head>')\nprint ('<body>')\nprint ('<h2>Hello Word! This is my first CGI program<\/h2>')\nprint ('<p>')\ntxt=ftrobopy.ftrobopy('auto')\nprint ("1<br\/>")\ntxt.play_sound(int(1),int(0))\nprint ("1A<br\/>")\nwhile not txt.sound_finished():   pass\nprint ("2<br\/>")\nMotor_links  = txt.motor(2)\nprint ("3<br\/>")\nMotor_links.setSpeed(512)\nprint ("4<br\/>")\nMotor_links.setDistance(500, syncto=0)\nprint ('5<br\/>')\nwhile not Motor_links.finished():\n  print ('r')\nprint ("<br \/>")\ntxt.stopOnline()\nprint ("End FT program<br\/>")\nprint ('<\/p>')\nprint ('<\/body>')\nprint ('<\/html>')<\/pre><\/div>\n\n\n\n
There are more options to use the public data area as document_root for the CivetWeb server.<\/p>\n\n\n\n
  • Change the document_root in a way that it point to under the user: ROBOPro accessible data area.<\/li>
  • start a new instance of the CivetWeb server on a different port (8081) and  document_root in a way that it point to under the user: ROBOPro accessible data area. <\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"
