php实现调用微信上传照片然后保存至服务器与数据库
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script><script type="text/javascript">
wx.config({
//debug: true,
appId: '{{$sites.appid}}',
timestamp: {{$timestamp}},
nonceStr: '{{$noncestr}}',
signature: '{{$signature}}',
jsApiList: [
'chooseImage',//拍照或从手机相册中选图接口
'previewImage',//预览图片接口
'uploadImage',//上传图片接口
'downloadImage',//下载图片接口

});
wx.ready(function(){
document.querySelector('#upimg').onclick = function(){
//选择照片
wx.chooseImage({
count: 1, //张数， 默认9
sizeType: ['compressed'], //建议压缩图
sourceType: ['album', 'camera'], // 来源是相册、相机
success: function (res) {
var localIds = res.localIds.toString();
$("#faceImg").attr("src", localIds);//显示图片到页面上
//上传至微信服务器
wx.uploadImage({
