我们有一个场景：使用微信小程序上传手机视频到OBS中，然后从OBS下载视频在小程序中播放。目前andorid手机可以上传视频并播放正常，但是IOS手机虽然上传成功但是不能正常播放视频。目前定位到的问题点是：把视频访问连接发送到微信群中，IOS手机是无法打开视频。也就是说可以排除小程序的影响因素。

php如何实现华为云obs跨区域复制

准备工作：申请一个OBS资源，创建一个桶。开启一个CloudIDE实例，打开一个terminal，先下载并安装obs的工具obsutil。配置obsutil:需要用到开发者的我的凭证->访问密钥->新建访问密钥的AK，SK。使用obsutil命令在桶中新建一个文件夹test

有增加用户自定义的元数据的api，但貌似没有看到可以删除的api？

请教一个问题，需要华为专业的帮助：我要遍历所有桶名，直接用官方提供obs的API代码，复制粘贴，然后直接运行就报错。错误是在huaweicloud-sdk-dotnet-obs-master源代码里抛出的。需要说明的是：这个.net版本的代码，在连接了互联网的机器上能够正常执行，是不会报错的。但是，由于我们的内网服务器不能连接互联网，是通过专线IPsec来实现对华为云的连接（在此条件下用obs客户端可以连接上并能正常操作云上的对象），并且用obs的java版本的代码也是可以正常执行。但是用obs的.net版本的程序执行却会报错！百思不得其解。报错情况，如下图：我调用执行的API代码，如下图：

【现象描述】通过外表从obs中导出数据有大量报错，例如1. duplicate key value violates unique constrain "xxxx"2.  null value in column "yyyy"3. 导入的数据中有大量非本数据文件中的内容【原因分析】obs中的文件名采用路径+文件拼写，读取时使用模糊匹配。当obs外表定义的路径中未加斜杠，且该路径下有其他类似的文件名，会导致obs读取到其他文件，入库时会出现各种违反约束的报错。即使能入库，也会出现非预期数据。【处理办法】定义外表在location的路径最后加斜杠，例如：/user/hive/warehouse/mppdb.db/region_orc11_64stripe/
