layui的html部分：
<div class="layui-upload">
<button type="button" class="layui-btn" id="wxsharepic">微信分享图</button>
<div class="layui-upload-list">
<img class="layui-upload-img" id="d1">
<p id="wxshareText"></p>
</div>
</div>
layui的Js部分：
//普通图片上传
var uploadInst = upload.render({
elem: '#wxsharepic'
,url: '/index.php/agent/agent/iconupload' //改成您自己的上传接口
,before: function(obj){
//预读本地文件示例，不支持ie8
obj.preview(function(index, file, result){
$('#d1').attr('src', result); //图片链接（base64）
});
}
,done: function(res){
//如果上传失败
if(res.code > 0){
return layer.msg('上传失败');
}
//上传成功
}
,error: function(){
//演示失败状态，并实现重传
var demoText = $('#wxshareText');
demoText.html('<span style="color: #FF5722;">上传失败</span> <a class="layui-btn layui-btn-xs demo-reload">重试</a>');
demoText.find('.demo-reload').on('click', function(){
uploadInst.upload();
});
}
});
thinkphp5.1的接收图片方法代码:
public function iconupload()
{
$icon = Request::file('file');
if($icon)
{
$info = $icon->validate([
'size'=>10240000,
'ext'=>'bmp,jpg,png,tif,gif,pcx,tga,exif,fpx,svg,psd,cdr,pcd,dxf,ufo,eps,ai,raw,WMF,webp'
])->move('uploads/usericon/');
if($info)
{
$url = "\\uploads\\usericon\\".$info->getSaveName();
return json(['status'=>100,'message'=>'上传成功','url'=>$url]);
}
else
{
return json(['status'=>-200,'message'=>$icon->getError(),'url'=>'\static\default_images\user_default_image.jpg']);
}
}
}
