小程序宿主环境 渲染层和逻辑层   小程序的运行环境分成渲染层和逻辑层:WXML 模板和 WXSS 样式工作在渲染层,JS 脚本工作在逻辑层。渲染层和数据相关;逻辑层负责产生、处理数据,通过 Page 实例的 data 属性传递数据到渲染层。 通信模型   小程序的渲染层和逻辑层分别由2个线程管理:渲染层的界面使用了WebView 进行渲染;逻辑层采用JsCore线程运行JS脚本。一个小程序存在多个界面,所以渲染层存在多个WebView线程,这两个线程的通信会经由微信客户端(下文中也会采用Native来代指微信客户端)做中转,逻辑层发送网络请求也经由Native转发,小程序的通信模型如下图所示: 程序与页面   从逻辑组成来说,一个小程序是由多个“页面”组成的“程序”。 程序   “小程序”指的是产品层面的程序,而“程序”指的是代码层面的程序实例。 程序构造器App()   宿主环境提供了 App() 构造器用来注册一个程序App。App() 构造器必须写在项目根目录的app.js里,App实例是单例对象,在其他JS脚本中可以使用宿主环境提供的 getApp() 来获取程序实例。 1 // other.js 2 var appInstance = getApp()   App() 的调用方式如上所示,App构造器接受一个Object参数,参数说明如下: 1 App({ 2

tap() vs subscribe() to set a class property

倖福魔咒の 提交于 2019-11-29 02:37:48
问题 I am very new to rxjs and was just wondering is it ok to setup a class property by piping the stream and tapping it, or it should i do it in the subscribe. To me either way works, just wonder if it is ok to do it as I see fit to my eyes or there is something I am unaware of. Typescript code demonstrating both ways: export class ViewComponent implements OnInit { applicant = {}; constructor(public route: ActivatedRoute, private store: Store<any>) {} ngOnInit() { this.route.paramMap.pipe(

How to tap (hook) F7 through F12 and Power/Eject on a MacBook keyboard

a 夏天 提交于 2019-11-28 12:46:48
This question follows from How to hook/remap an arbitrary keyboard event on OSX? So far I am able to tap the modifier keys and most of the other keys using: _eventTap = CGEventTapCreate( kCGHIDEventTap, kCGHeadInsertEventTap, kCGEventTapOptionDefault, CGEventMaskBit( kCGEventKeyDown ) | CGEventMaskBit( kCGEventFlagsChanged ) , (CGEventTapCallBack)_tapCallback, (__bridge void *)(self)); Notably, F3 correctly reports a keycode (160) before taking action. i.e. I can disable the action by having my event handler return NULL (and thus failing to propagate the event). However, F7 through F12 and

使用tap-minio-csv 我们可以将s3 中csv 的文件,通过singer 的target 写到不用的系统中,可以兼容 s3 的存储类型,以下是一个集成minio 的测试,将minio 中的csv 数据导入到pg中 环境准备 docker-compose 文件 version: "3" services: s3: image: minio/minio command: server /data ports: - "9000:9000" environment: - "MINIO_ACCESS_KEY=dalongapp" - "MINIO_SECRET_KEY=dalongapp" volumes: - "./data:/data" target: image: postgres:9.6.11 ports: - "5432:5432" environment: - "POSTGRES_PASSWORD:dalong" 创建bucket 并上传文件 文件格式 my_table.csv id,username,userage2,classinfo 1,"dalong",11,"v1" 2,"rong",29,"v2" 3,"appdemo",30,"v3" 4,"tetst",30,"v4" my_table2.csv id2,username2,userage3

Singer 修改tap-s3-csv 支持minio 连接

[亡魂溺海] 提交于 2019-11-28 06:02:06
singer 团队官方处了一个tap-s3-csv 的tap,对于没有使用aws 的人来说并不是很方便了,所以简单修改了 下源码,可以支持通用的s3 csv 文件的处理,同时发布到了官方pip 仓库中,方便大家使用。 以下是简单代码修改部分的说明,以及如何发布pip包 修改说明 主要是关于连接s3 的部分,因为tap-s3-csv 使用的是boto3 我们需要修改的就是关于boto3 连接s3 的部署 添加上 aws_access_key_id , aws_secret_access_key , endpoint_url 关于s3 自定义连接的说明,格式如下: s3_client = boto3.session.Session().client( service_name='s3', aws_access_key_id=aws_access_key_id, aws_secret_access_key=aws_secret_access_key, endpoint_url=endpoint_url, ) 几个需要修改的部分 s3.py get_input_files_for_table 部分,主要是传递参数的 修改如下: def get_input_files_for_table(config, table_spec, modified_since=None): bucket =

问题 I found the following tun\tap example program and can not get it to work: http://www.secdev.org/projects/tuntap_udp/files/tunproxy.py I have modified the following lines: f = os.open("/dev/tun0", os.O_RDWR) ifs = ioctl(f, TUNSETIFF, struct.pack("16sH", "toto%d", TUNMODE)) ifname = ifs[:16].strip("\x00") The first line was modified to reflect the real location of the driver. It was originally f = os.open("/dev/net/tun", os.O_RDWR) Upon running I get the following error: sudo ./tuntap.py -s
