遇到同样的问题,签名验证成功的,url自己写死试了好多种,就是无效签名。请问你解决了吗?
JSSDK调用,怎么一直提示invalid signature?调用微信JSSDK一直提示无效签名,用微信提供的工具检查了签名,都是比对得上的,也按照官方文档对url进行截取掉#,前后台的appid也是一样的,还是出现invalid signature,然后同样的前后台代码,用我同事的电脑调用是可以调微信jssdk的摄像头接口的,防火墙也是关闭了,都不行,这是什么问题呢? [图片] [图片] 下面是调用的代码 $(function(){ $(".butt").bind("click",function(){ console.log((location.href.split('#')[0])) var signUrl = encodeURIComponent(window.location.href.split('#')[0]); $.ajax({ url: "http://hzf.free.idcfengye.com/ncgascip-app/weixinsdk/config", method: "post", data: { url: signUrl }, success: function (data) { console.log(data);

wx.error(function (res) { console.log(res); }); wx.ready(function(){ wx.chooseImage({ count: 1, // 默认9 sizeType: ['compressed'], // 可以指定是原图还是压缩图,默认二者都有 sourceType: ['camera'], // 可以指定来源是相册还是相机,默认二者都有 success: function (res) { $("#photolist").html("");
