ATX [求助][iOS] 使用 appium 的 WDA 连跑中断开，请问哪位小伙伴有解决方法

匿名 · September 23, 2019 · Last by 张 replied at December 11, 2020 · 3064 hits

每次断开时间也不一致，有时候半小时，有时候一个半小时，有时候两个半小时，有小伙伴遇到过这种情况么？

环境信息：

python: 3.7.3
facebook-wda: 0.4.1
com.facebook.wda.runner: 6.0
xcode：10.3
mac os：10.14.6
设备：iphone5s（12.4.1）,iphone6p(12.1.4)

python 端报错日志

这里只能看出来是连接断了

E               urllib3.exceptions.ProtocolError: ('Connection aborted.', ConnectionResetError(54, 'Connection reset by peer'))

1、有可能是 iproxy 的问题，即使用了其他端口映射的工具也有可能出现类似的问题，只是时间问题，可以在 python 逻辑程序中的访问 WDA 的接口的时候来个 try except 来捕获异常，重试代理
2、从日志上看，工具运行时间的挺长的，内存使用率达到一定峰值也会销毁 WDA，首先看你的写的逻辑是不是死循环，死循环定时退出循环，来个@autoreleases清理下内存，如果不是的话也只能重试 WDA

匿名 #2 · September 26, 2019

对

ltyd5788 回复

非常感谢答复，我试了重试，但是因为是 xcodebuild 运行的 WDA 断开，重新运行 xcodebuild 启动 wda 服务后，就算服务起来了，用例也已经全部失败了，内存使用率这块不知道怎么控制，没有死循环，请问 wda 有提供清理内存的接口么？

ltyd5788 #3 · September 26, 2019

1、https://github.com/manishPatwari/WebDriverAgent 例子可以看提交的 commit，类似可以在 fb_tree、handleTap 等常用的方法对 xcuitest 相应的 api 嵌套@autoreleasepool ，可以及时释放内存，这种情况对于 Monkey 工具来说是有好处的，常规的业务自动化只能算是小优化吧，并不能解决你遇到的问题，重新看了下日志你这种情况更贴近第二种情况
2、页面底部存在 “加载更多” 功能，使用 XCUITEST 查找元素短时间内会频繁的创建对象，App 也会出现卡死的现象，可以找下有 Table 嵌套的 Cell 页面尝试复现，打开报告面板，观察 Memory 的变化，如果是这种情况解决方法需要研发配合下，具体可以看下 Appium issues 和 WDA issues

3、WDA 断开还有一种情况是端口转发的问题，我仔细复现过这个问题，iproxy 转发出现异常，实际 WDA 是正常运行的，当下一次在发送请求时 WDA 就挂了，所以需要在下一次向 WDA 发送请求时 kill iproxy、start iproxy，可以先加上类似的操作，以免干扰你的判断

匿名 #4 · September 27, 2019

对

ltyd5788 回复

谢谢，如果是第二种，appium 他们应该会做内存释放吧，而且我有时候会看到这样的日志"xcodebuild iscarding message, buffer is full"，感觉是你说的这种；对于 3，我做用例前置添加 killall iproxy && iproxy 8100 8100 ，每次用例开始都断掉重连，但是实际情况是用例都直接因为断开而失败了，这个地方该如何处理，搞好几天了，头都大了

这个 WDA 断开的问题，有谁遇到么，貌似是 result 文件太大导致"Failed to spawn process for sample: 34 - Result too large"

对

edsion 回复

没用的，如果是代理断开，重启 iproxy 可以，但如果不是代理断开，而是 wda 断开，即使重试，仍然连不上的，只能重新将 wda build 到手机上。

edsion #8 · October 11, 2019

“重新启动 appium” 和 “重新将 wda build 到手机上” 不是一回事吗

之前也遇到此问题,解决方案,以下几点,你逐一试试吧,
1.python3.7.3 升级为 python3.7.4 版本,上一版本有此问题
2.openssl 升级版本
3.防火墙看看关了吗?查看代码是否有循环请求,在同一命令循环快速请求时,报此错误
4.安装 conda,python 和 python3 都指向了 conda(实际就这个方法,碰对了)
挨个试试吧,试了多长时间我就不说了,反正坑到头了
