可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I've created a function that can build nested urls like so. I was wondering if there existed a more mainstream library to build urls / uris like this. I'd rather use a standard. utility.urlConstruct({ "scheme": "https://", "domain": "domain.com", "path": "/login", "query":{ "user":"thomasreggi", "from":utility.urlConstruct({ "scheme": "https://", "domain": "redirect.com", "path": "/funstuff", }), } }); Spits out https://domain.com/login?user=thomasreggi&from=https%3A%2F%2Fredirect.com%2Ffunstuff 回答1: The correct answer is node's built in URL

地推是 App 获客的一种有效方式,相比于线上推广,地推数据的监测更加困难。如何监测 App地推渠道流量,发掘出优质渠道、优质地域以及优质地 ?? 地推是 App 获客的一种有效方式,相比于线上推广,地推数据的监测更加困难。如何监测 App 地推渠道流量,发掘出优质渠道、优质地域以及优质地推员,是所有 App 市场推广和运营都需要解决的问题。 运营商、O2O、电商等行业,在渠道推广上会有大量地推场景,今天这篇文章就选取典型的地推案例 - 运营商在 App 地推中遇到的渠道监测问题、采用的方案和最终产生的价值,帮助更多 App 市场推广和运营提升工作效率。 一、问题 某省级运营商计划通过线下地推的方式推广一款 App,希望借此抢占线上流量。目前线下主要的推广渠道有三个,分别是营业厅服务人员推广、校园推广、地推代理推广。无论是哪一种渠道,推广场景都很类似:地推人员让目标用户扫描二维码,用户进入落地页下载 App ,然后注册激活。 在这个过程中如何进行渠道监测和绩效管理,即统计每个城市、每个营业厅、每个工作人员的推广效果,这就是一个巨大的考验了。以 iPhone 手机为例,我们只有 App Store 一个应用下载页面;面对来自四面八方的地推流量,我们该如何一一识别出来呢? 在这之前,该运营商采用人工手动记录的方式进行渠道监测,然后录入系统逐级上报。这是一种非常传统的方式,存在很多问题:

What are the actual differences between Scheme and Common Lisp? (Or any other two dialects of Lisp)

问题 Note: I am not asking which to learn, which is better, or anything like that. I picked up the free version of SICP because I felt it would be nice to read (I've heard good stuff about it, and I'm interested in that sort of side of programming). I know Scheme is a dialect of Lisp and I wondered: what is the actual difference is between Scheme and, say, Common Lisp? There seems to be a lot about 'CL has a larger stdlib...Scheme is not good for real-world programming..' but no actual thing

Can I use Common Lisp for SICP or is Scheme the only option?

时间秒杀一切 提交于 2019-12-03 00:29:37
问题 Also, even if I can use Common Lisp, should I? Is Scheme better? 回答1: You have several answers here, but none is really comprehensive (and I'm not talking about having enough details or being long enough). First of all, the bottom line: you should not use Common Lisp if you want to have a good experience with SICP. If you don't know much Common Lisp, then just take it as that. (Obviously you can disregard this advice as anything else, some people only learn the hard way.) If you already know

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I like to study languages outside my comfort zone, but I've had a hard time finding a place to start for functional languages. I heard a lot of good things about Structure and Interpretations of Computer Programs, but when I tried to read through it a couple of years ago it just

Xcodebuild命令使用

Xcodebuild简介 Xcodebuild是命令行工具包的其中一项。 命令行工具包(Command Line Tools)是一个轻量的、可以与XCode分开的、在Mac上单独下载的命令行工具包。 它有两部分组成:Mac OS SDK和用户系统库目录/usr/bin下的诸多命令工具。例如:gcc/g++编译器,make、git、nase、xcodebuild、xcrun等等。 命令行工具包(Command Line Tools)的安装 Xcode-select命令 xcode-select是Mac系统自带的命令行工具,属于用户系统内/usr/bin。当电脑上安装多个Xcode时,xcode-select用来选择命令行工具为哪一个版本的Xcode服务。 命令行工具安装指令:xcode-select --install 选择指定的Xcode路径:xcode-select --switch <path> 常见命令 man命令 man可以进行命令用法的在线文档查询,包括使用例子。比如:man xcodebuild。 xcpretty命令 命令行输出美化小工具,可以对错误,警告给予高亮显示。使用方式:xcodebuild | xcpretty xcrun命令 xcrun用于调用其他命令执行,如:xcrun xcodebuild。 xcrun的调用是基于xcode-select选择的工具链

iOS 唤起APP之URL Scheme

简单的说,由于苹果选择使用沙盒机制来保障用户的隐私和安全,APP只能访问自己沙盒数据,但同时也阻碍了应用间合理的信息共享。因此苹果提供了一个可以在APP之间跳转的方法: URL Scheme 。如果你的APP需要其他APP访问某些功能或者数据,那么你需要在你的APP定义一个相应的 URL Scheme 。当别的APP使用 URL Scheme 进行访问时,系统会根据 URL Scheme 进行匹配,从而来拉起对应的APP。 如果想要更清晰的认识 URL Scheme 电话,我们需要了解下面几个概念: URL (Uniform Resource Locator:统一资源定位器):也就是我们所属于的"网址",通过它我们可以访问到我们想要的服务和资源,并且 URL 也可以传递相应的参数,也就是我们常说的 GET 请求; URL 地址格式排列为: scheme://host:port/path ,举个栗子:https://www.jianshu.com/u/b09c13696e1c就是个典型的 URL ,而这个网址对应的 Scheme 就是 https ,标识的是一个 URL 中的一个位置――最初始的位置,也可以理解为一种协议头。而我们自定义的 URL Scheme 可以理解为一种自定义的协议。 根据我们上面对 URL Scheme 的理解,我们可以很轻易地理解,在以本地应用为主的 iOS

Turning structural recursion into accumulative recursion in Racket

不问归期 提交于 2019-12-02 23:33:39
问题 I have some code to find the maximum height and replace it with the associated name. There are separate lists for height and names, each the same length and non-empty. I can solve this using structural recursion but have to change it into accumulative, and I am unsure how to do that. All the examples I have seen are confusing me. Is anybody able to turn the code into one using accumulative recursion? (define (tallest names heights) (cond [(empty? names) heights] [(> (first heights) (first
