需要准备的
1.API密钥
SecretId 及 SecretKey 两部分,
SecretId 用于标识 API 调用者的身份,
SecretKey 用于加密签名字符串和服务器端验证签名字符串的密钥。
前往API密钥管理页面,即可进行获取
https://console.cloud.tencent.com/cam/capi
2. 图形验证码凭证
CaptchaAppId 是需要客户端页面传入,为了给后端进行校验
AppSecretKey 是密钥用,不可暴露在客户端,主要是后端进行调用
验证码密钥是构建腾讯验证码请求的重要凭证
前往验证码管理页面,即可进行
https://console.cloud.tencent.com/captcha/graphical?fromCode=true
下载证书
证书问题
如果您的 PHP 环境证书有问题,可能会遇到报错,类似于cURL error 60: See http://curl.haxx.se/libcurl/c/libcurl-errors.html
请尝试按以下步骤解决:
到 https://curl.haxx.se/ca/cacert.pem 下载证书文件cacert.pem,将其保存到 PHP 安装路径下。
编辑php.ini文件,删除curl.cainfo配置项前的分号注释符(;),
值设置为保存的证书文件cacert.pem的绝对路径。
重启依赖 PHP 的服务。
开启php_curl
注:代码是基于 tp5.0来的,只是一个参考
此 SDK 依赖的 GuzzleHttp 需要开启 php_curl 扩展,查看环境上的 php.ini 环境确认是否已启用
安装SDK包
composer require tencentcloud/tencentcloud-sdk-php
官网SDK调试
网址:https://console.cloud.tencent.com/api/explorer?Product=captcha&Version=2019-07-22&Action=DescribeCaptchaResult&SignVersion=
现阶段需要修改的
1.注册 {host}/index/index/reg.html
2.找回密码 {host}/index/index/find_password.html
配置项
根据tp5.0框架特性,扩展配置文件直接放入application/extra目录会自动加载
路径:application/extra/imgvalidate.php
<?php
return [
'captchaAppid' => '登录到腾讯云平台去拿', //每个医院的值需要配置下的
'captchaAppkey' => '登录到腾讯云平台去拿',
'secretId' => 'AKIDObZHismPkoc9OM3UdV6RVIn31i8HAl6H', //这是已经设定好了的
'secretKey' => '4tSkmSs10jAKDqBF2ZomTu4xa1FCsHQI',
'region' => 'ap-shanghai'
];
调用sdk封装类
路径:extend/sms/ImgValidate.php
<?php
namespace sms;
use TencentCloud\Captcha\V20190722\CaptchaClient;
use TencentCloud\Captcha\V20190722\Models\DescribeCaptchaResultRequest;

$this->_initConf($imgValidConf);
}
private function _initConf($imgValidConf)
{
if (empty($imgValidConf)) {
exception('腾讯云配置数据不能为空!', 9000);
}
if (empty($imgValidConf['secretId'])) {
exception('平台API的secretId不能为空!',9001);
}
if (empty($imgValidConf['secretKey'])) {

$this->_captKey = $imgValidConf['captchaAppkey'];
$this->_region = $imgValidConf['region'];
}
/**
* 从前端传过来的必要参数
* @param $ticket //用户在客户端验证成功的字符吗
* @param $randStr //用户在客户端验证完成的随机码
*/
public function sendCode($ticket, $randStr)
{
try {
$cred = new Credential($this->_secretId, $this->_secretKey);
$httpProfile = new HttpProfile();
$httpProfile->setEndpoint("captcha.tencentcloudapi.com");
$clientProfile = new ClientProfile();
$clientProfile->setHttpProfile($httpProfile);
$client = new CaptchaClient($cred, "", $clientProfile);
$req = new DescribeCaptchaResultRequest();
$params = array(
"CaptchaType" => 9,

];
wLog(var_export($logInfo, true), $allowIpInfo = null, $level = '腾讯云图形验证码异常:', 'tencentImgValid');
return false;
}
}
}
ctroller层调用
调用的API:
路径:application/api/controller/Imgvalidate.php
<?php
namespace app\api\controller;
use think\Exception;
class Imgvalidate
{
/**
* 腾讯云的图形验证码操作
* @return false|string
*/
public function dovalidate()
{
$randStr = Input('post.randstr');
$ticket = Input('post.ticket');
$account = input('post.account');
$imgConf = config('imgvalidate');
try {
$ImgValidate = new \sms\ImgValidate($imgConf);
$res = $ImgValidate->sendCode($ticket,$randStr);
if (!$res) {
$returnData = [
'code'=>500,
'msg'=>'failed'
];
} else {
//用来做token校验
$cacheKey = 'img_validate_'.$account;
$token = getImgvaldateToken($cacheKey);
cache($cacheKey,$token);
wLog($token, $allowIpInfo = null, $level = 'token-'.$cacheKey, $logPath = 'imgValidToken');
//记录当前时间
// $currentTime = time();
// cache('dovalid_time_'.$account, $currentTime);
$returnData = [
'code'=>200,
'data' => cache($cacheKey),
'msg' => 'success'
];
}
return json($returnData);
} catch (Exception $e) {
$logInfo = [
'code' => $e->getCode(),
'msg' => $e->getMessage()
];
wLog(var_export($logInfo,true),null,'腾讯云图形验证码异常:','tencentImgValid');
return json(['code'=>501,'msg'=>'failed']);
}
}
}
短信发送前的校验:
在application/api/controller/User.php加入检验token的代码
/**
* 校验token
* @param $account //手机号码或用户名
* @param $postSign
* @param $beforCheck
* @return array
*/
private function _checkSign($account, $postSign, $beforCheck=0)
{
if ($beforCheck == 1) { //是否需要检查用户信息是否存在
$Users=new Users();
$res = $Users->check_account($account);
if (!empty($res)) {
$returnData = ['code'=>0,'msg'=>'用户数据已经存在'];
return $returnData;
}
}
//获取在腾讯图形验证码生成时生成的token
$cacheKey = 'img_validate_'.$account;
$localSign = cache($cacheKey);
if (!$localSign) {
$returnData = ['code' => 0, 'msg' => '请求非法,请联系管理员'];
} else {
if ($postSign == $localSign) {
$returnData = ['code'=>1,'msg'=>'校验成功!'];
cache($cacheKey,null); //校验成功后把这个session删除掉。
// wLog($postSign, $allowIpInfo = null, $level = 'validSucc-'.$cacheKey, $logPath = 'imgValidSucc');
} else {
wLog($postSign, $allowIpInfo = null, $level = 'postsign-'.$cacheKey, $logPath = 'imgValidFaild');
$returnData = ['code'=>0,'msg'=>'校验失败!'];
}
}
return $returnData;
}
//发送短信校验码
public function send_verify()
{
$ip=$_SERVER["REMOTE_ADDR"];//ip
$id = 1;
$param = input('post.param');
$uv_r = input('post.uv_r');
$postSign = input('post.data');
$beforChk = input('post.beforchk',0);
$type = 'sms';
$tel = $param;//电话
//检查请求是否非法
$checkData = $this->_checkSign($tel, $postSign, $beforChk);
if ($checkData['code'] != 1) {
return json($checkData);
}
//判断数据是否超过了限制
// $uvr_num = $this->checkUvr($uv_r);
$tel_num = $this->checkTel($tel);
....
}
在注册、找回密码渲染页controller层加入appid
路径:application/index/controller/Index.php
namespace app\index\controller;
use app\common\model\Announcement;
use app\common\model\AnnouncementMiddle;
use app\common\model\Branch;
use app\common\model\ImagesHistoryModel;
use app\common\model\ImagesMilieuModel;
use app\common\model\Jobs;
use app\common\service\ConfigServer;
use think\Db;
class Index extends Base
{
....
//会员注册
public function reg() {
$this->set_seo('会员注册');
$imgConf = config('imgvalidate'); //获取扩展配置
$this->assign('appid',$imgConf['captchaAppid']); //前端页面需要用到appid
return $this->fetch();
}
//找回密码
public function find_password(){
$this->set_seo('找回密码');
$imgConf = config('imgvalidate');
$this->assign('appid',$imgConf['captchaAppid']);
return $this->fetch();
}
....
}
添加公共方法
在调用接口时,需要记录日志信息,方便来排查接口的错误信息,具体是在sdk封装类中使用
路径:application/common.php
/**
* 日志写入文件
* @param $msg 日志内容
* @param null $allowIpInfo 允许写入的ip
* @param string $level 层级
* @param string $logPath 日志路径
*/
function wLog($msg, $allowIpInfo = null, $level = 'msg', $logPath = '')
{
//授权给某个ip才能记录日志
if (!empty($allowIpInfo)) {
\think\Log::key(\think\Request::instance()->ip()); //获取当前的ip设置给日志
if (is_array($allowIpInfo)) {
$logConfig['allow_key'] = $allowIpInfo;
} elseif (is_string($allowIpInfo)) {
$logConfig['allow_key'] = [$allowIpInfo];
} else { //有可能ip经过转换
}
}
$logPath = !empty($logPath) ? 'log/'.$logPath : 'log';
$lastPath = RUNTIME_PATH .$logPath . DS;
if (!is_dir($lastPath)) {
mkdir($lastPath,0777,true);
}
$logConfig = [
'type' => 'File', //日志记录方式,内置 file socket 支持扩展
'path' => $lastPath, //日志保存目录
'file_size' => 2097152, //文件到了这个大小,自动生成下一个文件
'level' => [$level], //日志记录级别
'time_format' => 'c',
];
//记录日志
\think\Log::init($logConfig);
\think\Log::record($msg, $level);
}
/**
* 图形验证码中设置token,用来校验
* @param $data
* @param string $prefix
*/
function getImgvaldateToken($data,$prefix='hospitalname')
{
$data = $prefix ? $prefix.$data : $data;
return md5(md5($data));
}
前端步骤
前端地址 https://cloud.tencent.com/document/product/1110/36841
1.引用微信官方的js包
<script src="https://ssl.captcha.qq.com/TCaptcha.js"></script>
2. 发送验证码时候,data-appid,data-cbfn,data-biz-state不能为空
<a href="javascript:;" class="btn-send" data-appid="{$appid}" data-cbfn="callbackTentent" data-biz-state="data-biz-state" onclick="checkSmscode(this)">发送验证码</a>
3. 根据官方文档开启验证图层显示
var appId = String({$appid});
var captcha = new TencentCaptcha(appId,callbackTentent);
captcha.show(); // 显示验证码
具体代码
/**
* 获得腾讯图形验证码
* @param obj
*/
function checkSmscode(obj) {
var account=$(".find_account").val();
if(!account){
layer.msg('手机号不能为空!', {icon: 5});
}else{
//直接生成一个验证码对象。
try {
var appId = String({$appid});
var captcha = new TencentCaptcha(appId,callbackTentent);
captcha.show(); // 显示验证码
} catch (error) {
loadErrorCallback(error);
}
}
}
//图形验证码回调
function callbackTentent(res) {
if (res.ret === 0) {
var account = $(".find_account").val();
var uv_r = $(".uv_r").val();
$.ajax({
type: "POST",
url: "/api/imgvalidate/dovalidate",
data: {'ticket': res.ticket, 'randstr': res.randstr, 'account': account},
dataType: "json",
success: function (checkRes) {
// checkRes = JSON.parse(checkRes);
var obj = $(".btn-send");
if (checkRes['code'] == '200') {
var wait=60;
var timeId;
time(obj);
//验证码
$.ajax({
url: "/api/user/send_verify",
type: 'POST',
data: {id: 1, param: account, type: 'sms', uv_r: uv_r, data:checkRes['data']},
dataType: 'JSON',
success: function (ret) {
if (ret.code == 200) {
var wait=60;
var timeId;
time(obj);
layer.msg(ret.msg,{icon:1});
} else {
layer.msg(ret.msg, {icon: 5});
}
}
});
} else {
layer.msg('校验失败了,请联系管理员', {icon: 5});
}
}
});
} else {
layer.msg('加载验证码失败了,请联系管理员',{icon:5});
}
}
/**
* 抛出异常错误
* @param err
*/
function loadErrorCallback(err) {
console.log(err);
}
补充:
前端最好做成封装的,方便调用。
