大家好呀,这期是分享五行资源博客教程的:emlog网站非插件添加海报方法,这教程是需要动手改代码的,如果你看不懂代码的话,建议你还是不要上手了。注意:动手改之前,一定要备份好!
首先说说下面这两个文件
phpqrcode.php qrcode.php 这两个文件必须要用到 具体什么用处你不需要知道
步骤1
在你的模板创建个php文件例如我的haibao.php 创建好后你想放在那放在那 要记住路径 需要用到
<div class="dialog_overlay"></div>
<div class="bigger-share">
<div class="row-share">
<div class="img-share">
<img src="<?php echo poster_share($logid, Url::log($logid), img_url($thumbs,$logid,$log_content), $log_title, $date, $blogname, $bloginfo);?>" alt="<?php echo $log_title; ?>">
<div class="action-haibao">
<a href="<?php echo poster_share($logid, Url::log($logid), img_url($thumbs,$logid,$log_content), $log_title, $date, $blogname, $bloginfo);?>" download="<?php echo $log_title; ?>"><i class="fa fa-share-alt"></i></a>
</div>
</div>
<div class="share-item">
<h3>分享文本海报</h3>
<div class="button">
<a href="javascript:;" onclick="shareToWeibo('<?php echo Url::log($logid);?>','<?php echo $log_title;?>','<?php echo Url::log($logid);?>','')" title="分享到微博" class="btn btn-danger"><i class="fa fa-weibo"></i> 新浪微博</a>
</div>
<div class="button">
<a href="javascript:;" onclick="shareToQzone('<?php echo Url::log($logid);?>','<?php echo $log_title;?>','<?php echo Url::log($logid);?>')" title="分享到QQ好友" class="btn btn-info"> <i class="fa fa-qq"></i> QQ好友</a>
</div>
<div class="button">
<a href="javascript:;" onclick="shareToQzone('<?php echo Url::log($logid);?>','<?php echo $log_title;?>','<?php echo Url::log($logid);?>')" title="分享到QQ空间" class="btn btn-warning"> <i class="fa fa-qzone"></i> QQ空间</a>
</div>
<div class="button">
<a href="<?php echo poster_share($logid, Url::log($logid), img_url($thumbs,$logid,$log_content), $log_title, $date, $blogname, $bloginfo);?>" download="<?php echo $log_title; ?>" class="btn btn-primary">
<i class="fa fa-cloud-download"></i> 下载海报</a>
</div> </div>
<span class="share-close">
<i class="fa fa-close"></i>
</span>
<div class="text-weixin">
<p>长按图片转发给朋友</p>
</div>
</div>
</div>
创建好后开始第二步骤
步骤2
打开你的文章页 一般都是echo_log.php引入即可
引入代码:
<?php include View::getView('inc/haibao');?>
打开echo_log.php放入加载点
<a class="share-haibao"><i class="fa fa-share-alt"></i> 生成海报</a>
打开heeder.php载入
require_once View::getView('functions');
打开footer.php放在任意地方 即可
<?php include View::getView('inc/haibao');?>
放入js 如果你是用fee模板无需放入请忽略这步
$('.share-haibao').click(function() {
$('.bigger-share').addClass('haibao-on');
$('.dialog_overlay').show();
$('.dialog_overlay').click(function() {
$('.bigger-share').removeClass('haibao-on');
$('.dialog_overlay').hide();
});
});
$('.share-close').click(function() {
$('.bigger-share').removeClass('haibao-on');
$('.dialog_overlay').hide();
});
步骤3
新建一个functions.php放到模板目录里
<?php
/**
* 局部函数库
*/
if(!defined('EMLOG_ROOT')) {exit('error!');}
//获取图片
function img_url($thumburl,$gid,$content,$open=false){
if($thumburl){
return $thumburl;
}elseif(img_zw($content)){
return img_zw($content);
}elseif(img_fj($gid) && $open){
return img_fj($gid);
}else{
return TEMPLATE_URL.'images/post.jpg';
}
}
//抓取远程连接内容
function myCurl($url, $ip = '114.114.114.114'){
$ch = curl_init(); // Curl 初始化
$timeout = 30; // 超时时间:30s
$ua='Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'; // 伪造抓取 UA
curl_setopt($ch, CURLOPT_URL, $url); // 设置 Curl 目标
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Curl 请求有返回的值
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // 设置抓取超时时间
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // 跟踪重定向
curl_setopt($ch, CURLOPT_ENCODING, ""); // 设置编码
curl_setopt($ch, CURLOPT_REFERER, $url); // 伪造来源网址
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.$ip, 'CLIENT-IP:'.$ip)); //伪造IP
curl_setopt($ch, CURLOPT_USERAGENT, $ua); // 伪造ua
curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); // 取消gzip压缩
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$content = curl_exec($ch);
curl_close($ch); // 结束 Curl
return $content; // 函数返回内容
}
//海报图生成
function createSharePng($gData,$fileName){
//创建画布
$width = 600;
$height = 800;
$im = imagecreatetruecolor($width, $height);
//填充画布背景色
$color = imagecolorallocate($im, 255, 255, 255);

$source_path = myCurl($gData["pic"]);
$head_img = imagecreatefromstring($source_path);
$target_height = 480;
$target_width = 600;

}
// 裁剪

//时间
$day = date('d', $gData["date"]);

//返回浏览连接

//判断图片是否存在或已超过15天,创建缓存文件

//数据
$gData = [
'pic' => $pic,
'code' => $code,
'title' => $title,
'date' => $date,
'author' => $author,
'blogname' => $blogname,
'bloginfo' => $bloginfo
];
createSharePng($gData,$file);
}
return $src;
}
步骤4
创建图片上传路劲content/uploadfile/fee_file/poster/
打开content/uploadfile/
创建fee_file然后在打开此文件在创建poster即可

方法既然已经发出来了但是可能不怎么完整 一时间想不出来还有啥没写上去的
