电话号码可以带到发送短信界面，短信内容怎么带过去

startMMSAbilityExplicit() { 
  // 这里完善联系人和号码 
  let params: Array<Object> = [new Contact(“张三”, 13344556677)]; 
 
  let want: Want = { 
    bundleName: “com.ohos.mms”, 
    abilityName: “com.ohos.mms.MainAbility”, 
    parameters: { 
      contactObjects: JSON.stringify(params), 
      pageFlag: “conversation”, 
      // 这里填写短信内容 
      content: “内容” 
    } 
  }; 
  this.context.startAbilityForResult(want).then((data) => { 
    console.log(“Success” + JSON.stringify(data)) 
  }).catch(() => { 
    console.log(“error”) 
  }) 
}
