我在淘宝拿的图片很大张的，结果放到博客去变成很小张，我想应该用啥软件设置成不变的大尺寸？

Posted 2023-04-09

如题，我想要靠谱的答案，最好能教我使用，谢谢

呵呵，装个Photoshop 跟改一下图片的分辨率！网站上的图片分辨率一般都很小，建议用Photoshop CS4 !!! 参考技术A 是不是你的图片本身就是那么大呀，你得看一上你博客上放图片的地方是否比淘宝上的大。 参考技术B 如果你有P图软件 一般都可以将图片放大的 但图片变得模糊 一般的P图软件都可以 像美图秀秀之类的 参考技术C 用软件 制作一下就好了

微信jssdk上传图片，一张一张的上传 和 一次性传好几张

//html模板

<div class="zhaopin_3_2">
            <div id="bbb"></div>
            <img src="/Public/Home/images/jia.png" class="avatar-round1">
        </div>

 

此方法是一次可多张上传

//js控制

    
{:wx_jssdk_config("false")}
<script>
        var headimgurl;
        var y=0;
        var i =0;
        $(‘.avatar-round1‘).click(function(){
            if(y<5){
                var html = $(‘#bbb‘).html();
                wx.chooseImage({
                    count: 5-i,
                    success: function (res) {

                            var serverId = res.serverId; // 返回图片的服务器端ID
                            html += ‘<div class="uploadImg img"><div class="close"><img src="__HOME__/images/close.png" onclick="del_imgy(this);"> </div>‘+
                                        ‘<img src="‘+localId+‘"/><input type="hidden" name="image[]" value="‘+serverId+‘"></div>‘;
                            //其他对serverId做处理的代码
                            if(localIds.length > 0){
                                syncUpload(localIds);
                            }else{
                                $(‘#bbb‘).html(html);
                            }
                        }
                    });
                }; 
            } 
        });    

function del_img(dom){
    $(dom).parents(‘.uploadImg‘).remove();
}
</script>

 

//此方法可一张一张的上传

{:wx_jssdk_config("false")}
<script>
        var headimgurl;
        $(‘.avatar-round1‘).click(function(){
            wx.chooseImage({

                success: function(res) {
                    var localIds = res.localIds; // 返回选定照片的本地ID列表，localId可以作为img标签的src属性显示图片
                    // 上传照片
                    wx.uploadImage({
                        localId: ‘‘ + localIds,

                            $(localIds).each(function(index, el) {
                                iii=localIds[index];

                            });
                            var html = $(‘#bbb‘).html();
                            html += ‘<div class="uploadImg img" id="tuji"><div class="close"><img src="__HOME__/images/close.png" onclick="del_img(this);"> </div>‘+

        });


function del_img(dom){

            $(dom).parents(‘.uploadImg‘).remove();

}
 </script>

 

下面使用的方法都是一样的

//封装的方法
//我的是放在  function.php文件里

//下面这两个方法需要用到微信的配置

/**
 * 直接生成微信jssdk_config
 * @echo string $jssdk Jssdk_config
 * @author 5heAtMin9 <[email protected]>
 */

function wx_jssdk_config($debug=‘true‘){
    $getSignPackage = wx_getSignPackage();
    $jssdk = ‘<script src="https://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>‘;
    $jssdk .= ‘<script>
    wx.config({
        debug: ‘.$debug.‘, 
        appId: "‘.$getSignPackage[‘appId‘].‘",
        timestamp: "‘.$getSignPackage[‘timestamp‘].‘",
        nonceStr: "‘.$getSignPackage[‘nonceStr‘].‘",
        signature: "‘.$getSignPackage[‘signature‘].‘",
        jsApiList: ["checkJsApi","onMenuShareTimeline","onMenuShareAppMessage","onMenuShareQQ", "onMenuShareWeibo","onMenuShareQZone","hideMenuItems","showMenuItems","hideAllNonBaseMenuItem","showAllNonBaseMenuItem","translateVoice","startRecord","stopRecord","onVoiceRecordEnd","playVoice","onVoicePlayEnd","pauseVoice","stopVoice","uploadVoice","downloadVoice","chooseImage","previewImage","uploadImage","downloadImage","getNetworkType","openLocation","getLocation","hideOptionMenu","showOptionMenu","closeWindow","scanQRCode","chooseWXPay","openProductSpecificView","addCard","chooseCard","openCard"],
    });

}




//控制器里需要用到此方法
