信鴿推送 push API

參考： push_api_v3

0. 基本 push

const _ = require('lodash');
const fetch = require('node-fetch');
const CryptoJS = require('crypto-js');

// zh/en android/ios authorization
const XINGE_PARAMS = {
  zh: {
    android: {
      appId: '', // 需要替換成自己app的appId
      secretKey: '', // 需要替換成自己app的secretKey
    },
    ios: {
      appId: '',
      secretKey: '',
    },
  },
  en: {
    android: {
      appId: '',
      secretKey: '',
    },
    ios: {
      appId: '',
      secretKey: '',
    },
  },
};
const getAuthorization = (locale, platform) => {
  const { appId, secretKey } = XINGE_PARAMS[locale][platform];
  const str = `${appId}:${secretKey}`;
  const wordArray = CryptoJS.enc.Utf8.parse(str);
  const base64AuthString = CryptoJS.enc.Base64.stringify(wordArray);
  return base64AuthString;
};
const XINGE_AUTHORIZATIONS = ['zh', 'en'].reduce((authorizations, locale) => {
  const platforms = ['android', 'ios'].reduce((platformResult, platform) => {
    platformResult[platform] = getAuthorization(locale, platform);
    return platformResult;
  }, {});
  authorizations[locale] = platforms;
  return authorizations;
}, {});

// android/ios notification message;
const formatMessageByPlatform = (platform, custom = {}) => {
  if (platform === 'android') {
    return {
      android: {
        action: {
          action_type: 1,
        },
        custom_content: custom, //使用者自定義的鍵值對
      },
    };
  }

  return {
    ios: {
      aps: {
        alert: {},
        sound: 'default',
      },
      custom,
    }
  };
};

// common push, audience_type default value is all
const push = (params, audienceOptions) => {
  const { locale, platform, title, content, custom, environment = 'product' } = params;
  const authorization = XINGE_AUTHORIZATIONS[locale][platform];
  const otherMessage = formatMessageByPlatform(platform, custom);
  const environmentObj = platform === 'ios' ? { environment } : {};

  const data = Object.assign({
    audience_type: 'all',
    platform,
    ...environmentObj,
    message_type: 'notify',
    message: {
      title,
      content,
      ...otherMessage,
    },
  },
  audienceOptions);

  return fetch('https://openapi.xg.qq.com/v3/push/app', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `Basic ${authorization}`,
    },
    body: JSON.stringify(data),
  })
  .then((res) => res.json())
  .then((res) => console.log(res));
};
exports.push = push;
 

1. 根據 token list，推送到android和ios

function getTokensByPlatform(platform, tokens) {
  return tokens
    .filter((item) => item.platform === platform)
    .map((item) => item.token);
}

// 1. push to tokenList by tokens
exports.xgPushByTokens= (params, tokens) => {
  const androidParams = { platform: 'android', ...params };
  const androidTokens = getTokensByPlatform('android', tokens);
  const androidAudience = {
    audience_type: 'token_list',
    token_list: androidTokens,
  };

  const iosParams = { platform: 'ios', ...params };
  const iosTokens = getTokensByPlatform('ios', tokens);
  const iosAudience = {
    audience_type: 'token_list',
    token_list: iosTokens,
  };

  return Promise.all([
    _.isEmpty(androidTokens) ? Promise.resolve() : push(androidParams, androidAudience),
    _.isEmpty(iosTokens) ? Promise.resolve() : push(iosParams, iosAudience),
  ]);
};
 

2. 推送到android和ios 所有使用者

// 2. push to all
exports.xgPushAll = (params) => {
  const androidParams = { platform: 'android', ...params };
  const iosParams = { platform: 'ios', ...params };

  return Promise.all([
    push(androidParams),
    push(iosParams),
  ]);
};
