- 当前 Bug 的表现（可附上截图） [图片] - 预期表现 产品轮播图正常显示 问题说明： 小程序体验版本，在IOS真机上部分网络图片不显示，安卓系统和开发模拟器上正常，从未出现过该问题。 两个不同的IPhone手机，图片在另一个IOS手机上正常显示，但又会丢失其他图片，丢失图片完全是随机的(图片格式是jpg和png)，在图片上绑定了预览图片方法，执行wx.previewImage方法传入不显示的图片地址，可正常预览 和swiper标签没有任何关系，在page中直接一个image标签也会随机图片不显示。 在后台查看nginx日志发现 访问图片的时候会在 jpg或者png后面加上/ 导致404， 日志详情： [代码]2018/11/06 17:33:16 [error] 4776#5532: *417 "E:/card/shop/tab6_icon.png/index.html" is not found (3: The system cannot find the path specified), client: 115.60.16.122, server: www.m.baidu.com, request: "GET /card/shop/tab6_icon.png/ HTTP/1.1", host: "www.m.baidu.com", referrer: "https://servicewechat.com/wx9fcadf2030746bd2/0/page-frame.html"[代码] [代码]2018/11/06 17:33:16 [error] 4776#5532: *422 "E:/card/shop/product/show/liaoyiliao_icon.png/index.html" is not found (3: The system cannot find the path specified), client: 115.60.16.122, server: www.m.baidu.com, request: "GET /card/shop/product/show/liaoyiliao_icon.png/ HTTP/1.1", host: "www.m.baidu.com", referrer: "https://servicewechat.com/wx9fcadf2030746bd2/0/page-frame.html"[代码] [代码]2018/11/06 17:33:16 [error] 4776#5532: *420 "E:/card/shop/product/show/fenxiang.png/index.html" is not found (3: The system cannot find the path specified), client: 115.60.16.122, server: www.m.baidu.com, request: "GET /card/shop/product/show/fenxiang.png/ HTTP/1.1", host: "www.m.baidu.com", referrer: "https://servicewechat.com/wx9fcadf2030746bd2/0/page-frame.html"[代码] [代码]2018/11/06 17:33:16 [error] 4776#5532: *424 "E:/card/shop/product/show/shoucang.png/index.html" is not found (3: The system cannot find the path specified), client: 115.60.16.122, server: www.m.baidu.com, request: "GET /card/shop/product/show/shoucang.png/ HTTP/1.1", host: "www.m.baidu.com", referrer: "https://servicewechat.com/wx9fcadf2030746bd2/0/page-frame.html"[代码] [代码]2018/11/06 17:33:16 [error] 4776#5532: *424 "E:/files/20181017/0a73f4e7-14b8-4ea6-8a67-ad71f6fd83ba.jpg/index.html" is not found (3: The system cannot find the path specified), client: 115.60.16.122, server: www.m.baidu.com, request: "GET /files/20181017/0a73f4e7-14b8-4ea6-8a67-ad71f6fd83ba.jpg/ HTTP/1.1", host: "www.m.baidu.com", referrer: "https://servicewechat.com/wx9fcadf2030746bd2/0/page-frame.html"[代码]     4. nginx配置      [代码]listen       443 ssl;[代码][代码]server_name  www.baidu.com baidu.com;[代码][代码] [代码] [代码]if ($http_user_agent ~* "(Android|iPhone|Windows Phone|UC|Kindle)"){[代码][代码]      [代码][代码]return 301   https://www.m.baidu.com$request_uri;[代码][代码]}[代码] 日志和nginx配置信息中我个域名替换成baidu.com，能说明问题就行，在配置中判断如果是手机端访问，则return 301 配置二 [代码]listen       443 ssl;[代码][代码]server_name  www.m.baidu.com m.baidu.com;[代码] [代码]location ~/weixin/(card|files|wxxiaochengxuimgs) {[代码][代码]    [代码][代码]root   E:\images;[代码][代码]}[代码] 微信小程序访问图片服务器，从baidu.com   301到m.baidu.com，然后直接读取硬盘图片资源 [代码]<[代码][代码]swiper[代码] [代码]class[代码][代码]=[代码][代码]'swiper'[代码] [代码]circular [代码][代码]bindchange[代码][代码]=[代码][代码]'_swiperbindchange'[代码][代码]>[代码][代码]   [代码][代码]<[代码][代码]block[代码] [代码]wx:for[代码][代码]=[代码][代码]'{{imagesList}}'[代码] [代码]wx:key[代码][代码]=[代码][代码]"*this"[代码] [代码]wx:for-index[代码][代码]=[代码][代码]'idx'[代码][代码]>[代码][代码]     [代码][代码]<[代码][代码]swiper-item[代码][代码]>[代码][代码]       [代码][代码]<[代码][代码]view[代码] [代码]class[代码][代码]=[代码][代码]'productmasterimage'[代码][代码]>[代码][代码]         [代码][代码]<[代码][代码]image[代码] [代码]src[代码][代码]=[代码][代码]'{{item}}'[代码] [代码]mode[代码][代码]=[代码][代码]'aspectFill'[代码] [代码]style[代码][代码]=[代码][代码]'width:100%;height:750rpx;'[代码] [代码]bindtap[代码][代码]=[代码][代码]'showmasterimage'[代码] [代码]data-index[代码][代码]=[代码][代码]'{{idx}}'[代码][代码]/>[代码][代码]         [代码][代码]<[代码][代码]image[代码] [代码]class[代码][代码]=[代码][代码]'videoplay'[代码] [代码]wx:if[代码][代码]=[代码][代码]'{{videocheck&&idx==0}}'[代码] [代码]src[代码][代码]=[代码][代码]'{{video_big}}'[代码] [代码]style[代码][代码]=[代码][代码]'width:116rpx;height:116rpx;'[代码] [代码]bindtap[代码][代码]=[代码][代码]'_videoshow'[代码][代码]/>[代码][代码]       [代码][代码]</[代码][代码]view[代码][代码]>[代码][代码]     [代码][代码]</[代码][代码]swiper-item[代码][代码]>[代码][代码]   [代码][代码]</[代码][代码]block[代码][代码]>[代码][代码] [代码][代码]</[代码][代码]swiper[代码][代码]>[代码] 循环imagesList数组，image标签直接指向网络图片地址，网络协议是https， - 复现路径 疑问： 1.

在微信开发工具里面的调试器里debug，debug退出后调试器会卡住点不了，过一会儿控制台报如下错： Framework Event Listeners API Errors: fetcher call produced error: ReferenceError: Node is not define
