IOS系统部分图片不显示问题，求大神分析

• 当前 Bug 的表现（可附上截图）

• 预期表现

产品轮播图正常显示

问题说明：

1. 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。

2. 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

3. 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。

4. 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，

    4. nginx配置

 

listen       443 ssl; server_name  www.baidu.com baidu.com;    if ($http_user_agent ~* "(Android|iPhone|Windows Phone|UC|Kindle)"){       return 301   https://www.m.baidu.com$request_uri; }

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

listen       443 ssl; server_name  www.m.baidu.com m.baidu.com;   location ~/weixin/(card|files|wxxiaochengxuimgs) {     root   E:\images; }

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

<swiper class='swiper' circular bindchange='_swiperbindchange'>    <block wx:for='{{imagesList}}' wx:key="*this" wx:for-index='idx'>      <swiper-item>        <view class='productmasterimage'>          <image src='{{item}}' mode='aspectFill' style='width:100%;height:750rpx;' bindtap='showmasterimage' data-index='{{idx}}'/>          <image class='videoplay' wx:if='{{videocheck&&idx==0}}' src='{{video_big}}' style='width:116rpx;height:116rpx;' bindtap='_videoshow'/>        </view>      </swiper-item>    </block>  </swiper>

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. IOS部分网络图片随机不显示，是服务器并发到最到拒绝？但我nginx设置的是

worker_rlimit_nofile 65535;   events {     worker_connections 65535; }

2. nginx配置问题

但安卓和模拟器可以正常访问到图片

3. 404？

真机调试，console栏里什么都没输出，没任何错误

5. 图片路径在IOS上没赋值成功

打开Wxml查看好好的啊

已经查阅N多资料，折腾了两周，问题还没解决，或许就差那一点点，大神们和腾讯官方给协助一下，谢谢~~
