@ মেনু থেকে তৃতীয় পক্ষের সংস্থান তৈরি করুন

এই পৃষ্ঠাটি ব্যাখ্যা করে যে কীভাবে একটি Google Workspace অ্যাড-অন তৈরি করতে হয় যা Google ডক্স ব্যবহারকারীদের Google ডক্সের মধ্যে থেকে তৃতীয় পক্ষের পরিষেবাতে সহায়তার ক্ষেত্রে বা প্রজেক্ট টাস্কের মতো সংস্থান তৈরি করতে দেয়।

Google Workspace অ্যাড-অন দিয়ে, আপনি Docs-এর @ মেনুতে আপনার পরিষেবা যোগ করতে পারেন। অ্যাড-অন মেনু আইটেম যোগ করে যা ব্যবহারকারীদের ডক্সে একটি ফর্ম ডায়ালগের মাধ্যমে আপনার পরিষেবাতে সংস্থান তৈরি করতে দেয়।

ব্যবহারকারীরা কিভাবে সম্পদ তৈরি করে

একটি Google ডক্স ডকুমেন্টের মধ্যে থেকে আপনার পরিষেবাতে একটি সংস্থান তৈরি করতে, ব্যবহারকারীরা একটি নথিতে @ টাইপ করুন এবং @ মেনু থেকে আপনার পরিষেবা নির্বাচন করুন:

ব্যবহারকারী একটি কার্ডের পূর্বরূপ দেখেন

যখন ব্যবহারকারীরা একটি নথিতে @ টাইপ করেন এবং আপনার পরিষেবা নির্বাচন করেন, আপনি তাদের একটি কার্ডের সাথে উপস্থাপন করেন যাতে একটি সংস্থান তৈরি করার জন্য ব্যবহারকারীদের প্রয়োজনীয় ফর্ম ইনপুটগুলি অন্তর্ভুক্ত থাকে। ব্যবহারকারী সম্পদ তৈরির ফর্ম জমা দেওয়ার পরে, আপনার অ্যাড-অন আপনার পরিষেবাতে সংস্থান তৈরি করবে এবং এটিকে নির্দেশ করে এমন একটি URL তৈরি করবে।

অ্যাড-অন তৈরি করা সম্পদের জন্য নথিতে একটি চিপ সন্নিবেশ করায়। ব্যবহারকারীরা যখন এই চিপের উপরে পয়েন্টার ধরে রাখে, তখন এটি অ্যাড-অনের সংশ্লিষ্ট লিঙ্ক প্রিভিউ ট্রিগারকে আহ্বান করে। নিশ্চিত করুন যে আপনার অ্যাড-অন লিঙ্ক প্যাটার্ন সহ চিপগুলি সন্নিবেশ করাচ্ছে যা আপনার লিঙ্ক প্রিভিউ ট্রিগার দ্বারা সমর্থিত।

আপনার অ্যাড-অনের জন্য সংস্থান তৈরি সেট আপ করুন

এই বিভাগটি ব্যাখ্যা করে যে কীভাবে আপনার অ্যাড-অনের জন্য রিসোর্স তৈরি সেট আপ করবেন, যার মধ্যে নিম্নলিখিত পদক্ষেপগুলি অন্তর্ভুক্ত রয়েছে:

  1. আপনার অ্যাড-অনের ম্যানিফেস্টে সংস্থান তৈরি কনফিগার করুন ।
  2. আপনার পরিষেবার মধ্যে সংস্থান তৈরি করতে ব্যবহারকারীদের প্রয়োজন এমন ফর্ম কার্ডগুলি তৈরি করুন ৷
  3. ফর্ম জমাগুলি পরিচালনা করুন যাতে ব্যবহারকারীরা ফর্ম জমা দেওয়ার সময় সংস্থান তৈরি করে এমন ফাংশন চলে৷

সম্পদ তৈরি কনফিগার করুন

সম্পদ তৈরি কনফিগার করতে, আপনার অ্যাড-অনের ম্যানিফেস্টে নিম্নলিখিত বিভাগ এবং ক্ষেত্রগুলি নির্দিষ্ট করুন:

  1. docs ফিল্ডে addOns বিভাগের অধীনে, createActionTriggers ট্রিগার প্রয়োগ করুন যাতে একটি runFunction অন্তর্ভুক্ত থাকে। (আপনি নিম্নলিখিত বিভাগে এই ফাংশনটি সংজ্ঞায়িত করুন, ফর্ম কার্ড তৈরি করুন ।)

    createActionTriggers ট্রিগারে আপনি কোন ক্ষেত্রগুলি নির্দিষ্ট করতে পারেন সে সম্পর্কে জানতে, অন্যান্য রানটাইমের জন্য Apps স্ক্রিপ্ট ম্যানিফেস্ট বা স্থাপনার সংস্থানগুলির জন্য রেফারেন্স ডকুমেন্টেশন দেখুন৷

  2. oauthScopes ক্ষেত্রে, স্কোপ যুক্ত করুন https://www.googleapis.com/auth/workspace.linkcreate যাতে ব্যবহারকারীরা সংস্থান তৈরি করার জন্য অ্যাড-অনটিকে অনুমোদন করতে পারেন৷ বিশেষত, এই সুযোগ অ্যাড-অনকে তথ্য পড়তে দেয় যা ব্যবহারকারীরা রিসোর্স তৈরি ফর্মে জমা দেয় এবং সেই তথ্যের উপর ভিত্তি করে নথিতে একটি স্মার্ট চিপ সন্নিবেশ করে।

একটি উদাহরণ হিসাবে, একটি ম্যানিফেস্টের addons বিভাগটি দেখুন যা নিম্নলিখিত সমর্থন কেস পরিষেবার জন্য সংস্থান তৈরিকে কনফিগার করে:

{
  "oauthScopes": [
    "https://www.googleapis.com/auth/workspace.linkpreview",
    "https://www.googleapis.com/auth/workspace.linkcreate"
  ],
  "addOns": {
    "docs": {
      "linkPreviewTriggers": [
        ...
      ],
      "createActionTriggers": [
        {
          "id": "createCase",
          "labelText": "Create support case",
          "localizedLabelText": {
            "es": "Crear caso de soporte"
          },
          "runFunction": "createCaseInputCard",
          "logoUrl": "https://www.example.com/images/case.png"
        }
      ]
    }
  }
}

উদাহরণে, Google Workspace অ্যাড-অন ব্যবহারকারীদের সহায়তা কেস তৈরি করতে দেয়। প্রতিটি createActionTriggers ট্রিগারে নিম্নলিখিত ক্ষেত্র থাকতে হবে:

  • একটি অনন্য আইডি
  • একটি পাঠ্য লেবেল যা দস্তাবেজ @ মেনুতে প্রদর্শিত হয়৷
  • @ মেনুতে লেবেল পাঠ্যের পাশে প্রদর্শিত একটি আইকনের দিকে নির্দেশ করে একটি লোগো URL৷
  • একটি কলব্যাক ফাংশন যা হয় একটি Apps স্ক্রিপ্ট ফাংশন বা একটি HTTP এন্ডপয়েন্ট যা একটি কার্ড ফেরত দেয়

ফর্ম কার্ড তৈরি করুন

ডক্স @ মেনু থেকে আপনার পরিষেবাতে সংস্থান তৈরি করতে, আপনি createActionTriggers অবজেক্টে নির্দিষ্ট করেছেন এমন যেকোনো ফাংশন বাস্তবায়ন করতে হবে।

যখন একজন ব্যবহারকারী আপনার মেনু আইটেমগুলির একটির সাথে ইন্টারঅ্যাক্ট করে, তখন সংশ্লিষ্ট createActionTriggers ট্রিগার ফায়ার করে এবং এর কলব্যাক ফাংশন রিসোর্স তৈরির জন্য ফর্ম ইনপুট সহ একটি কার্ড উপস্থাপন করে।

সমর্থিত উপাদান এবং কর্ম

কার্ড ইন্টারফেস তৈরি করতে, আপনি তথ্য এবং ইনপুটগুলি প্রদর্শন করতে উইজেট ব্যবহার করেন যা ব্যবহারকারীদের রিসোর্স তৈরি করার জন্য প্রয়োজন। বেশিরভাগ Google Workspace অ্যাড-অন উইজেট এবং অ্যাকশন নিম্নলিখিত ব্যতিক্রমগুলির সাথে সমর্থিত:

  • কার্ড ফুটার সমর্থিত নয়।
  • বিজ্ঞপ্তি সমর্থিত নয়।
  • নেভিগেশনের জন্য, শুধুমাত্র updateCard নেভিগেশন সমর্থিত।

ফর্ম ইনপুট সহ কার্ডের উদাহরণ

নিম্নলিখিত উদাহরণটি একটি Apps স্ক্রিপ্ট কলব্যাক ফাংশন দেখায় যা একটি কার্ড প্রদর্শন করে যখন একজন ব্যবহারকারী @ মেনু থেকে সমর্থন কেস তৈরি করুন নির্বাচন করেন:

ফর্ম ইনপুট সহ কার্ড

কার্ডটিতে পাঠ্য ইনপুট, একটি ড্রপ-ডাউন মেনু এবং একটি চেকবক্স অন্তর্ভুক্ত রয়েছে। এটিতে একটি onClick অ্যাকশন সহ একটি পাঠ্য বোতাম রয়েছে যা তৈরি ফর্ম জমা দেওয়ার জন্য অন্য একটি ফাংশন চালায়।

ব্যবহারকারী ফর্মটি পূরণ করে Create এ ক্লিক করার পর, অ্যাড-অন ফর্ম ইনপুটগুলিকে onClick অ্যাকশন ফাংশনে পাঠায়- যাকে আমাদের উদাহরণে submitCaseCreationForm বলা হয়- যেখানে অ্যাড-অন ইনপুটগুলিকে যাচাই করতে পারে এবং সম্পদ তৈরি করতে ব্যবহার করতে পারে। তৃতীয় পক্ষের পরিষেবা।

ফর্ম জমা হ্যান্ডেল

একজন ব্যবহারকারী তৈরি ফর্ম জমা দেওয়ার পরে, onClick অ্যাকশনের সাথে যুক্ত ফাংশনটি চলে। একটি আদর্শ ব্যবহারকারীর অভিজ্ঞতার জন্য, আপনার অ্যাড-অন সফল এবং ভ্রান্ত ফর্ম জমা উভয়ই পরিচালনা করবে।

সফল সম্পদ সৃষ্টি হ্যান্ডেল

আপনার অ্যাড-অনের onClick ফাংশনটি আপনার তৃতীয় পক্ষের পরিষেবাতে সংস্থান তৈরি করবে এবং এটিকে নির্দেশ করে এমন একটি URL তৈরি করবে।

চিপ তৈরির জন্য রিসোর্সের ইউআরএল ডক্সে ফেরত পাঠানোর জন্য, onClick ফাংশনটি renderActions.action.links এ একটি এক-উপাদান অ্যারে সহ একটি SubmitFormResponse ফেরত দিতে হবে যা একটি লিঙ্কের দিকে নির্দেশ করে। লিঙ্কের শিরোনামটি তৈরি করা সংস্থানের শিরোনামকে উপস্থাপন করা উচিত এবং URLটি সেই সংস্থানটির দিকে নির্দেশ করা উচিত।

একটি Google ডক্স ডকুমেন্টের মধ্যে থেকে আপনার পরিষেবাতে একটি সংস্থান তৈরি করতে, ব্যবহারকারীরা একটি নথিতে @ টাইপ করুন এবং @ মেনু থেকে আপনার পরিষেবা নির্বাচন করুন:

ব্যবহারকারী একটি কার্ডের পূর্বরূপ দেখেন

যখন ব্যবহারকারীরা একটি নথিতে @ টাইপ করেন এবং আপনার পরিষেবা নির্বাচন করেন, আপনি তাদের একটি কার্ডের সাথে উপস্থাপন করেন যাতে একটি সংস্থান তৈরি করার জন্য ব্যবহারকারীদের প্রয়োজনীয় ফর্ম ইনপুটগুলি অন্তর্ভুক্ত থাকে। ব্যবহারকারী সম্পদ তৈরির ফর্ম জমা দেওয়ার পরে, আপনার অ্যাড-অন আপনার পরিষেবাতে সংস্থান তৈরি করবে এবং এটিকে নির্দেশ করে এমন একটি URL তৈরি করবে।

অ্যাড-অন তৈরি করা সম্পদের জন্য নথিতে একটি চিপ সন্নিবেশ করায়। ব্যবহারকারীরা যখন এই চিপের উপরে পয়েন্টার ধরে রাখে, তখন এটি অ্যাড-অনের সংশ্লিষ্ট লিঙ্ক প্রিভিউ ট্রিগারকে আহ্বান করে। নিশ্চিত করুন যে আপনার অ্যাড-অন লিঙ্ক প্যাটার্ন সহ চিপগুলি সন্নিবেশ করাচ্ছে যা আপনার লিঙ্ক প্রিভিউ ট্রিগার দ্বারা সমর্থিত।

আপনার অ্যাড-অনের জন্য সংস্থান তৈরি সেট আপ করুন

এই বিভাগটি ব্যাখ্যা করে যে কীভাবে আপনার অ্যাড-অনের জন্য রিসোর্স তৈরি সেট আপ করবেন, যার মধ্যে নিম্নলিখিত পদক্ষেপগুলি অন্তর্ভুক্ত রয়েছে:

  1. আপনার অ্যাড-অনের ম্যানিফেস্টে সংস্থান তৈরি কনফিগার করুন ।
  2. আপনার পরিষেবার মধ্যে সংস্থান তৈরি করতে ব্যবহারকারীদের প্রয়োজন এমন ফর্ম কার্ডগুলি তৈরি করুন ৷
  3. ফর্ম জমাগুলি পরিচালনা করুন যাতে ব্যবহারকারীরা ফর্ম জমা দেওয়ার সময় সংস্থান তৈরি করে এমন ফাংশন চলে৷

সম্পদ তৈরি কনফিগার করুন

সম্পদ তৈরি কনফিগার করতে, আপনার অ্যাড-অনের ম্যানিফেস্টে নিম্নলিখিত বিভাগ এবং ক্ষেত্রগুলি নির্দিষ্ট করুন:

  1. docs ফিল্ডে addOns বিভাগের অধীনে, createActionTriggers ট্রিগার প্রয়োগ করুন যাতে একটি runFunction অন্তর্ভুক্ত থাকে। (আপনি নিম্নলিখিত বিভাগে এই ফাংশনটি সংজ্ঞায়িত করুন, ফর্ম কার্ড তৈরি করুন ।)

    createActionTriggers ট্রিগারে আপনি কোন ক্ষেত্রগুলি নির্দিষ্ট করতে পারেন সে সম্পর্কে জানতে, অন্যান্য রানটাইমের জন্য Apps স্ক্রিপ্ট ম্যানিফেস্ট বা স্থাপনার সংস্থানগুলির জন্য রেফারেন্স ডকুমেন্টেশন দেখুন৷

  2. oauthScopes ক্ষেত্রে, স্কোপ যুক্ত করুন https://www.googleapis.com/auth/workspace.linkcreate যাতে ব্যবহারকারীরা সংস্থান তৈরি করার জন্য অ্যাড-অনটিকে অনুমোদন করতে পারেন৷ বিশেষত, এই সুযোগ অ্যাড-অনকে তথ্য পড়তে দেয় যা ব্যবহারকারীরা রিসোর্স তৈরি ফর্মে জমা দেয় এবং সেই তথ্যের উপর ভিত্তি করে নথিতে একটি স্মার্ট চিপ সন্নিবেশ করে।

একটি উদাহরণ হিসাবে, একটি ম্যানিফেস্টের addons বিভাগটি দেখুন যা নিম্নলিখিত সমর্থন কেস পরিষেবার জন্য সংস্থান তৈরিকে কনফিগার করে:

{
  "oauthScopes": [
    "https://www.googleapis.com/auth/workspace.linkpreview",
    "https://www.googleapis.com/auth/workspace.linkcreate"
  ],
  "addOns": {
    "docs": {
      "linkPreviewTriggers": [
        ...
      ],
      "createActionTriggers": [
        {
          "id": "createCase",
          "labelText": "Create support case",
          "localizedLabelText": {
            "es": "Crear caso de soporte"
          },
          "runFunction": "createCaseInputCard",
          "logoUrl": "https://www.example.com/images/case.png"
        }
      ]
    }
  }
}

উদাহরণে, Google Workspace অ্যাড-অন ব্যবহারকারীদের সহায়তা কেস তৈরি করতে দেয়। প্রতিটি createActionTriggers ট্রিগারে নিম্নলিখিত ক্ষেত্র থাকতে হবে:

  • একটি অনন্য আইডি
  • একটি পাঠ্য লেবেল যা দস্তাবেজ @ মেনুতে প্রদর্শিত হয়৷
  • @ মেনুতে লেবেল পাঠ্যের পাশে প্রদর্শিত একটি আইকনের দিকে নির্দেশ করে একটি লোগো URL৷
  • একটি কলব্যাক ফাংশন যা হয় একটি Apps স্ক্রিপ্ট ফাংশন বা একটি HTTP এন্ডপয়েন্ট যা একটি কার্ড ফেরত দেয়

ফর্ম কার্ড তৈরি করুন

ডক্স @ মেনু থেকে আপনার পরিষেবাতে সংস্থান তৈরি করতে, আপনি createActionTriggers অবজেক্টে নির্দিষ্ট করেছেন এমন যেকোনো ফাংশন বাস্তবায়ন করতে হবে।

যখন একজন ব্যবহারকারী আপনার মেনু আইটেমগুলির একটির সাথে ইন্টারঅ্যাক্ট করে, তখন সংশ্লিষ্ট createActionTriggers ট্রিগার ফায়ার করে এবং এর কলব্যাক ফাংশন রিসোর্স তৈরির জন্য ফর্ম ইনপুট সহ একটি কার্ড উপস্থাপন করে।

সমর্থিত উপাদান এবং কর্ম

কার্ড ইন্টারফেস তৈরি করতে, আপনি তথ্য এবং ইনপুটগুলি প্রদর্শন করতে উইজেট ব্যবহার করেন যা ব্যবহারকারীদের রিসোর্স তৈরি করার জন্য প্রয়োজন। বেশিরভাগ Google Workspace অ্যাড-অন উইজেট এবং অ্যাকশন নিম্নলিখিত ব্যতিক্রমগুলির সাথে সমর্থিত:

  • কার্ড ফুটার সমর্থিত নয়।
  • বিজ্ঞপ্তি সমর্থিত নয়।
  • নেভিগেশনের জন্য, শুধুমাত্র updateCard নেভিগেশন সমর্থিত।

ফর্ম ইনপুট সহ কার্ডের উদাহরণ

নিম্নলিখিত উদাহরণটি একটি Apps স্ক্রিপ্ট কলব্যাক ফাংশন দেখায় যা একটি কার্ড প্রদর্শন করে যখন একজন ব্যবহারকারী @ মেনু থেকে সমর্থন কেস তৈরি করুন নির্বাচন করেন:

ফর্ম ইনপুট সহ কার্ড

কার্ডটিতে পাঠ্য ইনপুট, একটি ড্রপ-ডাউন মেনু এবং একটি চেকবক্স অন্তর্ভুক্ত রয়েছে। এটিতে একটি onClick অ্যাকশন সহ একটি পাঠ্য বোতাম রয়েছে যা তৈরি ফর্ম জমা দেওয়ার জন্য অন্য একটি ফাংশন চালায়।

ব্যবহারকারী ফর্মটি পূরণ করে Create এ ক্লিক করার পর, অ্যাড-অন ফর্ম ইনপুটগুলিকে onClick অ্যাকশন ফাংশনে পাঠায়- যাকে আমাদের উদাহরণে submitCaseCreationForm বলা হয়- যেখানে অ্যাড-অন ইনপুটগুলিকে যাচাই করতে পারে এবং সম্পদ তৈরি করতে ব্যবহার করতে পারে। তৃতীয় পক্ষের পরিষেবা।

ফর্ম জমা হ্যান্ডেল

একজন ব্যবহারকারী তৈরি ফর্ম জমা দেওয়ার পরে, onClick অ্যাকশনের সাথে যুক্ত ফাংশনটি চলে। একটি আদর্শ ব্যবহারকারীর অভিজ্ঞতার জন্য, আপনার অ্যাড-অন সফল এবং ভ্রান্ত ফর্ম জমা উভয়ই পরিচালনা করবে।

সফল সম্পদ সৃষ্টি হ্যান্ডেল

আপনার অ্যাড-অনের onClick ফাংশনটি আপনার তৃতীয় পক্ষের পরিষেবাতে সংস্থান তৈরি করবে এবং এটিকে নির্দেশ করে এমন একটি URL তৈরি করবে।

চিপ তৈরির জন্য রিসোর্সের ইউআরএল ডক্সে ফেরত পাঠানোর জন্য, onClick ফাংশনটি renderActions.action.links এ একটি এক-উপাদান অ্যারে সহ একটি SubmitFormResponse ফেরত দিতে হবে যা একটি লিঙ্কের দিকে নির্দেশ করে। লিঙ্কের শিরোনামটি তৈরি করা সংস্থানের শিরোনামকে উপস্থাপন করা উচিত এবং URLটি সেই সংস্থানটির দিকে নির্দেশ করা উচিত।
