How to generate text CAPTCHA by Unity

Editor to share with you how to generate Unity text verification code, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Text verification code

Since I often use Unity to develop webgl versions, I see a lot of CAPTCHA verification when users log in to the site. The tool class text verification code of Unity is written as follows:

Tool class: VerificationCode

Using System.Collections;using System.Collections.Generic;using System.Text / the tool class is: generate CAPTCHA / / author: hys/// time: 2019.12.30 shock / E-mail: 840917807@qq.com/// public class VerificationCode {private static char [] constant = {'0pm] constant = {' 0# * $$} 1, # 2, 3, 4, 5, 6, 7, 7, 8, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 4, 4, 4, 4, 4, 6, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9 'fendy, makeshift, pageantry, pageantry, punitive, wishy-washy, wishy-washy-wishy-wishy- 'Lindsay, recorder, etc. / get the randomly generated CAPTCHA / length / public static string SetDeleKey (int Length) {StringBuilder newRandom = new StringBuilder (62); System.Random rd = new System.Random (); for (int I = 0; I < Length; iCAPTCHA +) {newRandom.Append (certificate [rd.Next (62)]) / / rd.Next (62) returns a non-negative random number less than 62, and Append splices Length sub-random codes} return newRandom.ToString ();}}

Unity script

Using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.UI;public class HuangVerificationCodeTextScripts: MonoBehaviour {private Text verificationCodeText; / / CAPTCHA Text. Private void Awake () {init ();} void Start () {} void Update () {} / initialize / private void init () {verificationCodeText = GameObject.Find ("VerificationCodeText") .GetComponent () } / generate CAPTCHA / CAPTCHA length / CAPTCHA of string type public string generateVerificationCode (int length) {string code= VerificationCode.SetDeleKey (length); verificationCodeText.text = code; return code;}} above is all the content of the article "how to generate text CAPTCHA by Unity".
