I am trying to Build server for testing on Linux(Alma linux 9 VM) NAME="AlmaLinux" VERSION="9.7 (Moss Jungle Cat)" ID="almalinux" ID_LIKE="rhel centos fedora" VERSION_ID="9.7" PLATFORM_ID="platform:el9" PRETTY_NAME="AlmaLinux 9.7 (Moss Jungle Cat)" ANSI_COLOR="0;34"

[azuki@AlmaDevVM ~]$ uname -m x86_64

I have tried the following steps:

  1. Before starting, ensured that Swift 6 installed. Referred https://www.swift.org/install/ for instructions.

  2. Build the library

In Terminal, uses the following commands to compile the Swift library: cd Development/Key_Server_Module/Swift swift build -Xbuild-tools-swiftc -DTEST_CREDENTIALS

  1. After building the library, ran test cases to ensure the library behaves as expected. ALL unit tests are passing with the development credentials.

• Since I was using an x86_64 machine: export LD_LIBRARY_PATH=./Sources/prebuilt/x86_64-unknown-linux-gnu/

Run all tests: swift test -Xbuild-tools-swiftc -DTEST_CREDENTIALS --disable-swift-testing

  1. Build the server

Build the server: Apache Before starting, ensured the following: a. Installed Apache HTTPD and the dev tools. Using the following command for installation: yum install httpd httpd-devel redhat-rpm-config b. After this, integrated it into the Apache server environment with swift library that was built above. Used the following command to build the server using apxs: • Since I was using an x86_64 machine: apxs -i -a -c
-Wl,-L${PWD}/.build/x86_64-unknown-linux-gnu/debug/
-Wl,-lswift_fpssdk
-Wl,-L${PWD}/Sources/prebuilt/x86_64-unknown-linux-gnu -lfpscrypto
-Wl,-R${PWD}/.build/x86_64-unknown-linux-gnu/debug
server_setup/mod_fps.c

c. Next, copied the dependent libraries to the Apache modules folder using these commands: • If using an x86_64 machine: cp Sources/prebuilt/x86_64-unknown-linux-gnu/libfpscrypto.so /usr/lib64/httpd/modules/libfpscrypto.so cp .build/x86_64-unknown-linux-gnu/debug/libswift_fpssdk.so /usr/lib64/httpd/modules/libswift_fpssdk.so

d. Configuring Apache HTTPD Configured Apache HTTPD by adding the module and handler to your Apache HTTPD configuration (/etc/httpd/conf/httpd.conf). Note that the apxs command may automatically add the LoadModule line in the previous step. Listen 8080 LoadFile /usr/lib64/httpd/modules/libfpscrypto.so LoadFile /usr/lib64/httpd/modules/libswift_fpssdk.so LoadModule fps_module /usr/lib64/httpd/modules/mod_fps.so <Location "/fps"> SetHandler fps_handler </Location> Copy the credentials to the Apache modules folder. cp -r ../credentials /usr/lib64/httpd/modules/ export FPS_CERT_PATH=
/usr/lib64/httpd/modules/credentials/test_certificates.json e. Run your server You can run the Apache HTTPD server with the configured module by using the following command: httpd -D FOREGROUND

No issues see till step.

Get SDK version [azuki@AlmaDevVM Key_Server_Module]$ curl localhost:8080/fps/v 26.0.0

But when i try to generate license [azuki@AlmaDevVM Key_Server_Module]$ curl -d ../Test_Inputs/iOS/spc_ios_hd_lease_2048.json localhost:8080/fps {"fairplay-streaming-response":{"create-ckc":[{"id":1,"status":-42601}]}}

Can you please suggest what i might be missing here?

This looks like a problem with your curl command. Can you try the following?

curl -d @Test_Inputs/iOS/spc_ios_hd_lease_2048.json localhost:8080/fps

The @ symbol is needed to send the contents of the file. Otherwise, curl just sends the filename as a string in the body of the request, and the server will respond with that error. Also, it looks like you are running from the Key_Server_Module directory, so the relative path is probably Test_Inputs instead of ../Test_Inputs.

Tried this. Now I see curl: (52) Empty reply from server


 curl -d @Test_Inputs/iOS/spc_ios_hd_lease_2048.json localhost:8080/fps

curl: (52) Empty reply from server [azuki@AlmaDevVM Key_Server_Module]$

Any further help would be highly appreciated. Is it specific to this OS? Any other working reference would be helpful.

  1. Please verify that your apache server is still running, for example by doing version check: "curl localhost:8080/fps/v"
  2. Check that in the folder where you run "curl -d @Test_Inputs/iOS/spc_ios_hd_lease_2048.json localhost:8080/fps" you can access the SPC request you are sending to the server, for example by running:

"ls Test_Inputs/iOS/spc_ios_hd_lease_2048.json"

I have confirmed that server is running. I am able to get version

[azuki@AlmaDevVM ~]$ cd server_setup/FairPlay_Streaming_Server_SDK_26/FairPlay_Streaming_Server_SDK_26/Development/Key_Server_Module/

[azuki@AlmaDevVM Key_Server_Module]$ ls

credentials parse_fps Rust Swift Test_Inputs

[azuki@AlmaDevVM Key_Server_Module]$ curl localhost:8080/fps/v

26.0.0

I had tried few more requests and i noticed same response for all

[azuki@AlmaDevVM Key_Server_Module]$ curl -d @Test_Inputs/iOS/spc_ios_hd_lease_2048.json localhost:8080/fps

curl: (52) Empty reply from server

[azuki@AlmaDevVM Key_Server_Module]$ curl -d @Test_Inputs/tvOS/spc_tvos_get_client_info_1024.json localhost:8080/fps

curl: (52) Empty reply from server


[azuki@AlmaDevVM Key_Server_Module]$ curl -d @Test_Inputs/iOS/spc_v3_ios_uhd_no_lease_2048.json localhost:8080/fps

Two things you could try that may give some clue as to why it's not working:

  1. Review apache logs in /etc/httpd/logs/error_log
  2. Run the curl command with -v or --trace -

Thanks for the sugegstions

I ran the curl with -v option

[azuki@AlmaDevVM Key_Server_Module]$ curl -v -d @Test_Inputs/iOS/spc_v3_ios_uhd_no_lease_2048.json localhost:8080/fps

Also when I checked httpd logs I do see a couple of errors.

I hope this helps to understand what might be the issue.
