记录一个海报批量生成、邮件批量发送功能开发，业务场景如下：
国外客户做观展预登记，工作人员通过后台，批量给这些观众生成入场证件并发送到观众登记的邮箱，以方便观众入场时快速进场。证件信息包含入场二维码、姓名；需要批量生成证件和批量发送邮件功能。
实现步骤大概如下：
index页面增加三个按钮，三个按钮的html如下：
<a class="btn btn-info btn-change btn-start" data-params="" data-url="miniform/guojihaibao/getdata" href="javascript:;"><i class="fa fa-play"></i> 批量获取登记数据</a>
<a class="btn btn-success btn-disabled disabled btn-selected" href="javascript:;"><i class="fa fa-magic"></i> 批量生成海报</a>
<a class="btn btn-warning btn-disabled disabled btn-sendemail" href="javascript:;"><i class="fa fa-leaf"></i> 批量发送邮件</a>1、批量获取登记数据；
后端
public function getdata(){
$row = $this->model->query("SELECT a.name,a.email,a.qrcode
FROM fa_miniform_di53jieguojimingjiajudongguanzhanlanhui a LEFT JOIN fa_haibao_guoji b
ON a.email=b.email
WHERE b.email IS NULL AND lang='en';");
// dump($row);exit;
if(!$row) $this->error('没有登记数据');
$insert = $this->model->insertAll($row);
if($insert){
$this->success('同步了'.count($row).'条数据');
}
}2、批量生成海报；
前端JS
// 批量生成海报
$(document).on("click", ".btn-selected", function () {
let ids = Table.api.selectedids(table) //获取选中的条目ID集合
ids.forEach(function(value,index) {
let row = Table.api.getrowbyid(table, value) //根据主键ID获取行数据
if(row.url_image){
Toastr.error(row.name+'已生成海报');
return false;
}
$.ajax({
type: "GET",
url: "miniform/guojihaibao/get_poster" + '/ids/' + value,
cache: false,
success: function(data) {
Toastr.info(data.msg);
}
});
});
table.bootstrapTable('refresh',{});
});后端
//生成海报
public function get_poster($ids=null){
if(!$ids) $this->error('ids参数缺失');
$row = $this->model->get($ids);
$fileUrl = '/uploads/qrcode/haibao/'. $row->qrcode.'.jpg';
$filename = ROOT_PATH .'public'. $fileUrl;
//生成用户二维码
$qrInfo = Haibao::buildQrcode($row->qrcode,'');
$config = array(
'image'=>array(
array(
'url'=>$qrInfo, //二维码地址
'is_yuan'=>false, //true图片圆形处理
'stream'=>0,
'top'=>1140,
'right'=>0,
'width'=>500, //图像宽
'height'=>500, //图像高
'opacity'=>100 //透明度
),
),
'text'=>array(
array(
// 'text'=>$userInfo['invite_code'], //文字内容
'text'=>$row->name,
'left'=>-1, //小于0为水平居中
'top'=>1750,
'fontSize'=>38, //字号
'fontColor'=>'88, 133, 44', //字体颜色
'angle'=>0,
'fontPath'=>ROOT_PATH.'/public/assets/fonts/SourceHanSansK-Regular.ttf', //字体文件
)
),
'background'=>cdnurl($this->background,true), //背景图
);
Haibao::createPoster($config,$filename);
$url = cdnurl($fileUrl,true);
if($url){
$update = $this->model->save(['url_image'=>$fileUrl],['id'=>$ids]);
if($update) $this->success('生成成功',$url);
}
}其中生成二维码和生成海报引入了另外一个类文件Haibao
<?php

// 生成二维码
public static function buildQrcode($text,$label)

$qrCode->writeFile($filePath);
return $filePath;
}
/**

public static function createPoster($config = array() , $filename = "") {
//如果要看报什么错，可以先注释调这个header

//处理了图片
if (!empty($config['image'])) {
foreach ($config['image'] as $key => $val) {
$val = array_merge($imageDefault, $val);
$info = getimagesize($val['url']);
$function = 'imagecreatefrom' . image_type_to_extension($info[2], false);
if ($val['stream']) { //如果传的是字符串图像流
$info = getimagesizefromstring($val['url']);
$function = 'imagecreatefromstring';
}
$res = $function($val['url']);
$resWidth = $info[0];

// imageColorTransparent($canvas, $color); //颜色透明
}
}
//关键函数，参数（目标资源，源，目标资源的开始坐标x,y, 源资源的开始坐标x,y,目标资源的宽高w,h,源资源的宽高w,h）
imagecopyresampled($canvas, $res, 0, 0, 0, 0, $val['width'], $val['height'], $resWidth, $resHeight);
//$val['left'] = $val['left']<0?$backgroundWidth- abs($val['left']) - $val['width']:$val['left'];
//如果left小于-1我这做成了计算让其水平居中
if ($val['left'] < 0) {
$val['left'] = ceil($backgroundWidth - $val['width']) / 2;
}
$val['top'] = $val['top'] < 0 ? $backgroundHeight - abs($val['top']) - $val['height'] : $val['top'];
//放置图像
imagecopymerge($imageRes, $canvas, $val['left'], $val['top'], $val['right'], $val['bottom'], $val['width'], $val['height'], $val['opacity']); //左，上，右，下，宽度，高度，透明度
}
}
//处理文字
if (!empty($config['text'])) {
foreach ($config['text'] as $key => $val) {
$val = array_merge($textDefault, $val);
list($R, $G, $B) = explode(',', $val['fontColor']);
$fontColor = imagecolorallocate($imageRes, $R, $G, $B);
//$val['left'] = $val['left']<0?$backgroundWidth- abs($val['left']):$val['left'];
//如果left小于-1我这做成了计算让其水平居中
if ($val['left'] < 0) {
$fontBox = imagettfbbox($val['fontSize'], 0, $val['fontPath'], $val['text']); //文字水平居中实质

imagettftext($imageRes, $val['fontSize'], $val['angle'], $val['left'], $val['top'], $fontColor, $val['fontPath'], $val['text']);
}
}

if (!$res) return false;
return $filename;
} else {
header("Content-type:image/png");
imagejpeg($imageRes); //在浏览器上显示
imagedestroy($imageRes);
}
}
}
3、批量发送邮件；
前端JS
// 批量发送邮件
$(document).on("click", ".btn-sendemail", function () {
let ids = Table.api.selectedids(table) //获取选中的条目ID集合
ids.forEach(function(id,index) {
let row = Table.api.getrowbyid(table, id) //根据主键ID获取行数据
if(row.send_email){
Toastr.error(row.name+'有发送记录');
return false;
}
if(!row.url_image){
Toastr.error(row.name+'无海报，请先生成');
return false;
}
$.ajax({
type: "GET",
url: 'miniform/guojihaibao/email_api?image='+row.url_image+'&email='+row.email+"&ids="+row.id,
cache: false,
success: function(data) {
Toastr.info(data.msg);
}
});
});
table.bootstrapTable('refresh',{});
});后端
/*
*英文--提交email
*/
public function email_api($ids=null,$email=null,$image=null){
if (!preg_match('/^[^\s@]+@[^\s@]+\.[^\s@]+$/', $email)) $this->error('邮箱正则不通过');
if(!$image) $this->error('无海报');
$url = 'xxx';
$title = 'VIP badge to participate the 53rd International Famous Furniture Fair (Dongguan)';
$fsr='FURNITRUE FAIR (DONGGUAN)';
// dump($image);
$neirong = '<img src="'.cdnurl($image,true).'">';
// $email = 'zhanpeng.wang@qq.com';
$params = ['title'=>$title,'fsr'=>$fsr,'neirong'=>$neirong,'youxiang'=>$email];
// dump($params);exit;
$result = \fast\Http::post($url, $params);
if($result){
$result = json_decode($result,true);
if($result['code']==200){
$this->model->save(['send_email'=>time()],['id'=>$ids]);
// $row = $this->model->get($ids);
// dump();exit;
// $row->send_email = time();
// $row->save();
$this->success($result['message']);
}else{
$this->error($result['message']);
}
}else{
$this->error('API接口错误');
}
}最终实现后台管理效果如下：
生成海报的效果
客户收到邮件的效果（每个邮件平台不一样，仅作参考）
