github部署gitpages静态网站踩坑 一、下载代码1.https协议下载https://github.com/{username}/{projectName}.git缺点：在 clone 或者 pull/push 的时候经常报错：fatal: unable to access 'https://github.com/{username}/{projectName}.git/': OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054解决办法：git config --global http.sslVerify 'false'执行该命令后马上执行 clone/pull/push 命令2.git协议下载git://github.com/{username}/{projectName}.git缺点：无法使用git协议执行 push 命令，会提示要使用https。3.ssh协议下载git@github.com:{username}/{projectName}.git需要设置publicKey二、gitpages静态网站部署publicPath 或者 base 要设置为 . ，否则部署后，js/css和图片等文件找不到路径，报错 404。路由模式选择 history 模式，但是不出意外的，history 模式下，从非首页进入站点时会提示找不到路径，报错 404 。解决办法：在打包后h5后的文件目录下，新建一个和 index.html 同级的 404.html 文件

IOS上架app出现“您的 App 包含 NSUserTrackingUsageDescription....” 您的 App 包含 NSUserTrackingUsageDescription，这表示您将会请求追踪用户。要在 App 产品页上更新此信息，您必须注明哪些数据类型会追踪用户。如果此描述有误，请更新您的 App 二进制文件，并将新的构建版本上传到 App Store Connect。具体原因：12年9月份iOS6发布，IDFA面世，主要用于给开发者跟踪应用中广告的投放效果，但很多应用（或三方SDK）会获取IDFA作为设备唯一标识使用。iOS14.5 发布之后，苹果要求应用获取 IDFA 时，需弹出用户许可收集跟踪数据的授权框，如果没有弹出授权框则可能会被App Store审核拒绝，提示违反5.1.2规则：解决办法：取消勾选该服务配置开启广告标识（IDFA）在 manifest.json 文件的 “App常用其它设置” 中可勾选开启（注意HBuilder X 2.4以上为默认勾选），需提交云端打包才会生效在低版本的HBuilder是默认勾选，可以将这个勾选给去掉，重新打包后提交应用到AppStore。
