Question

请教一个鸿蒙开发中打开系统邮箱并且展示邮件地址的问题？通过Want和context打开了系统邮箱，但是要发送的邮件地址，能通过哪个参数传过去（邮箱地址默认展示在打开的系统邮箱里，就像手机号，直接展示在拨打电话的页面），Want中的Uri还是其他参数，如何拼接？

Answer 1

可以通过拼接uri传递收件人，抄送人，内容等参数，关键代码参考如下：

mail({ subject= '', recipients=[], body='', ccRecipients=[], bccRecipients=[] }: mainOptions, callback: Function) { 
  let mailUri: string = ''; 
  mailUri += recipients?.join(',') || ''; 
  mailUri += '?cc=' + ccRecipients?.join(',') || ''; 
  mailUri += '&bcc=' + bccRecipients?.join(',') || ''; 
  mailUri += '&subject=' + subject; 
  mailUri += '&body=' + body; 
  Logger.info('mailUri ', mailUri, 'ccRecipients:' + ccRecipients, 'bccRecipients:' + bccRecipients); 
  this.startEmailApp(mailUri, callback); 
} 
 
startEmailApp = (mailUri, callback) => { 
  let want: Want = { 
    bundleName: 'com.huawei.hmos.email', 
    abilityName: 'EntryAbility', 
    moduleName: 'entry', 
    uri: 'mailto:' + mailUri, 
    action: 'ohos.want.action.viewData', 
  }; 
  Logger.info('want ', JSON.stringify(want)); 
  try { 
    this.ctx.uiAbilityContext.startAbility(want) 
      .then(() => { 
        Logger.info('startAbility success'); 
      }) 
      .catch((err: BusinessError) => { 
        Logger.info('startAbility error.', err.message); 
        callback(err.message); 
      }) 
  } catch (e) { 
    callback(e); 
    Logger.info('error:', e); 
  } 
}
