我一直在研究这样的正则表达式，我需要检查字符串，使其至少包含 3 个大写字母和至少 3 个数字，术语不应包含特殊。字符，即字符串中只能包含大写字母、数字和小写字母。也许有人知道如何编写这样的正则表达式？）

面对这样的问题，无法向服务器发送http请求。抛出错误“未指定网络安全配置，使用平台默认值”。我将 android:usesCleartextTraffic="true" 添加到清单中，但没有帮助。对于发送，我使用 Khttp 库。也许有人遇到过类似的问题。

override fun getToken(email: String, password: String) {

    val client = OkHttpClient()

    val formBody = FormBody.Builder()
        .add("email", "artur.yashchenko@nure.ua")
        .add("password", "123123")
        .build()
    val request = Request.Builder()
        .url("http://192.168.0.101:8080/login")
        .post(formBody)
        .build()

    try {
        val response = client.newCall(request).execute()
        print(response.body)
        // Do something with the response.
    } catch (e: IOException) {
        e.printStackTrace()
    }

}
