मैं Capistrano 3 (lib / capistrano / कार्य / संशोधन) में एक कस्टम कार्य लिख रहा हूं जो कर्ल के माध्यम से चल रहे एप्लिकेशन के संशोधन को प्राप्त कर रहा है।
फिर यह नवीनतम तैनात के साथ चल रहे संस्करण की तुलना करता है और उनकी तुलना करता है, अगर वे समान नहीं हैं तो एक त्रुटि फेंक दी जानी चाहिए।
मुझे इस बात पर ध्यान दिया गया कि रनिंग एप्लिकेशन का रिविजन किया गया है और एक एरर फेंकने के लिए एक खाली स्ट्रिंग की तुलना में।
समस्या यह है कि मैं इस कार्य का उत्पादन सुंदर नहीं है, यह सिर्फ सादे सफेद पाठ है
मैं क्या खो रहा हूँ? मैं पूरे दिन प्रलेखन में खुदाई कर रहा हूं।
सादर!

उत्तर:
उत्तर № 1 के लिए 1कोर में हल की जा रही एक समान समस्या का एक अच्छा उदाहरण यहां है: https://github.com/capistrano/capistrano/blob/master/lib/capistrano/tasks/deploy.rake#L91
उन पंक्तियों के साथ, आप "कोड को कुछ इस तरह चाहते हैं:
task :httpapi do
on roles(:httpapi), in: :sequence do |host|
puts "Checking revision of httpapi on #{host}"
response = capture "curl -L "http://#{fetch(:diagnostics_username)}:#{fetch(:diagnostics_password)}@#{host}/diagnostics/status?mode=extended&output=detailed""
object = JSON.parse(response, object_class: OpenStruct)
unless object.result.revision == "" #For test, just compare to empty string so error is thrown
error "The running revision is not the same as the installed, please restart all applications"
exit 1
end
end
