如何使用带有flutter的URL_launcher包发送短信? [英] How to send sms with URL_launcher package with flutter?

问题描述

您好，我搜索了一个简单的示例(Android和iOS)，以与此包一起发送短信

Hello I search a simple example (Android and iOS) to send SMS with this package

https://pub.dartlang.org/packages/url_launcher

在插件页面中，我仅看到如何使用电话号码打开短信本机应用程序，但没有多余的消息

In the plugin page I only see how to open sms native app with phone number, but no extra message

sms:<phone number>, e.g. sms:5550101234 Send an SMS message to <phone 
number> using the default messaging app

推荐答案

在Android上，完整的sms: URI受支持，您可以发送带有这样的正文的消息(

On Android the full sms: URI is supported and you can send a message with a body like that (RFC5724):

 _textMe() async {
    // Android
    const uri = 'sms:[phone]?body=hello%20there';
    if (await canLaunch(uri)) {
      await launch(uri);
    } else {
      // iOS
      const uri = 'sms:0039-222-060-888?body=hello%20there';
      if (await canLaunch(uri)) {
        await launch(uri);
      } else {
        throw 'Could not launch $uri';
      }
    }
  }

在

On iOS the official doc says you can only use the number field of The URI.

代替 Konstantine 所指出的那样，如果您使用非标准的URI，并且使用&代替，而不使用?开始查询字符串，则仍然可以正常使用.似乎是一个未记录的功能.

Instead as Konstantine pointed out, if you use a non standard URI and instead and instead of starting the query string with ? you use & it still works as well. It seems like an undocumented feature.

短信计划用于启动消息"应用.网址格式 这种类型是"sms:"，其中是可选参数 指定SMS消息的目标电话号码.这 参数可以包含数字0到9和加号(+)，连字符 (-)和句点(.)字符. URL字符串不得包含任何 消息文字或其他信息.

The sms scheme is used to launch the Messages app. The format for URLs of this type is "sms:", where is an optional parameter that specifies the target phone number of the SMS message. This parameter can contain the digits 0 through 9 and the plus (+), hyphen (-), and period (.) characters. The URL string must not include any message text or other information.

PS.要检查平台，您可以使用 dart.io库Platform类:

PS. to check the plaform you could use the dart.io library Platform class:

 _textMe() async {
    if (Platform.isAndroid) {
      const uri = 'sms:[phone]?body=hello%20there';
      await launch(uri);
    } else if (Platform.isIOS) {
      // iOS
      const uri = 'sms:0039-222-060-888&body=hello%20there';
      await launch(uri);
    }
  }
