Sign

Intro

This example sends a signing request to the fiskaltrust.Service via REST.

A zero receipt is sent to a specified url and CashBox and the response is printed.

Note: If the http statuscode 204 is returned the CashBox may not yet be activated and you'll need to send a start receipt first. For instructions on how to do this please consult our videos about sending requests to the fiskaltrust.Service

This example can be used as a starting point to implement the fiskaltrust.Interface

Note: The german cash transaction is being implemented at the moment in the fiskaltrust.Service. Since the implementation is similar, you can use the austrian service for testing.

Requirements

Toolchain

To compile the example the C compiler gcc and the buildtool make is needed.

Note: On windows we recommend installing these with a package manager like scoop or chocolatey

curl

To build the example, the curl library needs to be available.

Note: We tested the example with version 7.x.x, other versions may not work.

Windows

The curl library can be downloaded as pre compiled libraries. Please downlaod the prebuild libraries (curl, OpenSSL, brotli, libssh2, nghttp2, zlib) from here

Please copy libbrotlicommon-static.a, libcurl*.dll, libnghttp*.a, libssh*.dll,libssl*.dll, libcrypto*.dll and libz*.a to the .\build\ folder

Note: This list of libraries will be reminded by executing the program from a window, in the error message.

curl certificate is included in the curl zip file, next to the libcurl*.dll, copy curl-ca-bundle.crt to this project folder.

Linux

Install the library via your distributions package manager.

Distribution	Command
Ubuntu/Debian	apt-get install libcurl4 libcurl4-openssl-dev
Fedora	dnf install libcurl
OpenSUSE	zypper install libcurl4 libcurl4-openssl-dev

json-c

This JSON parser is used in this project.

Windows

Build the library open the VS 2015 command prompt, navigate to the json-c folder and using the following commands:

mkdir build
cd build
cmake ../
cmake --build . --target install

Note: To run these commands the VS build tools need to be installed.

After the library is compiled, the file json-c.dll has to be copied to C:\Windows\System32 or to .\build\.

Linux

To complile the library follow those instructions.

Note: You may also have to look into the Install prerequisites.

Building

Linux

1. Run the make command.

Windows

1. Run the powershell script configure.ps1 and follow the instructions.
2. Run the make command.

Example:

.\configure.ps1
make
