PHP Composer自动加载不起作用,没有启动类

Heroku PHP应用程序在本地工作,如果我推送供应商目录,则在部署时工作,但如果我不推送供应商目录则不行

<div class="post-text" itemprop="text"> <p>This is very confusing to me. I have built a simple heroku app. It works fine locally. It actually works fine on Heroku IF I push the vendor directory, but then heroku warns me that I should not push the composer vendor directory. The message directs me to a link that instructs me to use composer.lock file for dependencies. So I added a .gitignore to ignore the vendor directory and pushed again, but when I did that, the app doesn't work. I checked the file structure on the heroku remote and it appears dependencies were installed correctly, but the app doesn't work. I'm trying to do this the right way, so I really want this to work, even though I know I can just push my vendor folder and it will work.

Golang-跳过SSL / x509验证并构建软件包?

<div class="post-text" itemprop="text"> <p>I know nothing about the Go language, I'd just like to use this app on Ubuntu 14:</p> <ul> <li><a href="https://github.com/mvdan/fdroidcl" rel="nofollow noreferrer">https://github.com/mvdan/fdroidcl</a></li> </ul> <p>Before doing anything, I had to <a href="https://stackoverflow.com/questions/21001387/how-do-i-set-the-gopath-environment-variable-on-ubuntu-what-file-must-i-edit/21012349#21012349">set the GOPATH environment variable in my ~/.bashrc</a>. Then the README says this program is installed with:</p> <pre><code>go get -u github.com/mvdan/fdroidcl/cmd/fdroidcl </code></pre> <p>This passes fine, and an executable is found. In fact, these are the files found in home, where <code>GOPATH</code> is <code>~/go</code>:</p> <pre><code>$ find ~ -name 'fdroidcl*' 2&gt;/dev/null /home/myusername/.cache/fdroidcl /home/myusername/.config/fdroidcl /home/myusername/go/pkg/gccgo_linux_386/github.com/mvdan/fdroidcl /home/myusername/go/src/github.com/mvdan/fdroidcl /home/myusername/go/src/github.com/mvdan/fdroidcl/cmd/fdroidcl /home/myusername/go/bin/fdroidcl </code></pre> <p>Nice, but now when I start the initial command:</p> <pre><code>$ fdroidcl updateDownloading https://f-droid.org/repo/index.jar... update: could not update index: Get https://f-droid.org/repo/index.jar: x509: certificate signed by unknown authority (possibly because of "x509: cannot verify signature: algorithm unimplemented" while trying to verify candidate authority certificate "COMODO RSA Certification Authority") </code></pre> <p>This is most likely a failure due to self-signed certificate. A quick fix would be to use <code>http://</code> instead of <code>https://</code> (in case of <code>f-droid.org</code> it is currently possible), so I tried changing <code>~/go/src/github.com/mvdan/fdroidcl/cmd/fdroidcl/main.go</code>:</p> <pre><code>var config = userConfig{ Repos: []repo{ { ID: "f-droid", //URL: "https://f-droid.org/repo", URL: "http://f-droid.org/repo", Enabled: true, }, { ID: "f-droid-archive", //URL: "https://f-droid.org/archive", URL: "http://f-droid.org/archive", Enabled: false, }, }, } </code></pre> <p>... but the command is actually binary:</p> <pre><code>$ file $(which fdroidcl) ~/go/bin/fdroidcl: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=cd1dc87b54f9023983511ef46fda15a4d88dcb2d, not stripped </code></pre> <p>... which means I'd have to somehow re-build this application from source in order to get those changes in - how would I do that?</p> <p>Furthermore, there may be other apps with self-signed https certificates that would break, so I'd much rather skip SSL / X509 verification. It seems that, as <a href="https://stackoverflow.com/questions/12122159/golang-how-to-do-a-https-request-with-bad-certificate">golang: How to do a https request with bad certificate?</a> points out, that one should do in code:</p> <pre><code>tr := http.DefaultTransport.(*http.Transport) tr.TLSClientConfig.InsecureSkipVerify = true </code></pre> <p>... which again requires hacking/recompiling the source code - but isn't there some sort of a environment variable to help that, like <a href="https://stackoverflow.com/questions/11621768/how-can-i-make-git-accept-a-self-signed-certificate/19363404#19363404"><code>GIT_SSL_NO_VERIFY</code> for <code>git</code></a>?</p> </div>

副业收入是我做程序媛的3倍,工作外的B面人生是怎样的?

提到“程序员”,多数人脑海里首先想到的大约是:为人木讷、薪水超高、工作枯燥…… 然而,当离开工作岗位,撕去层层标签,脱下“程序员”这身外套,有的人生动又有趣,马上展现出了完全不同的A/B面人生! 不论是简单的爱好,还是正经的副业,他们都干得同样出色。偶尔,还能和程序员的特质结合,产生奇妙的“化学反应”。 @Charlotte:平日素颜示人,周末美妆博主 大家都以为程序媛也个个不修边幅,但我们也许...

记录下入职中软一个月(外包华为)

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

月薪22K程序员,打卡迟到10次,收到工资短信一脸懵逼

每家公司为了保证公司员工每天的工作时间,一般都会采用上下班打卡的工作制度,这其实是一个很常见的是,本身也没有什么问题的。正所谓无规矩不成方圆,公司肯定是有公司的规矩,虽然每个员工都很不喜欢这些规矩来束缚我们,但是公司也只是为了能更好的管理员工。但是一家公司如果一成不变的使用打卡制度,而不会去变通管理,也真不一定是好事。 打卡制度特别对于销售部门来说,不但会让公司发展不起来,还很容易丢失员工。但如...
