为什么有些大公司技术弱爆了?

这是我个人觉得蛮有意思的一篇文章,不是说里面的问题,而是两方暴露出来的问题现象,我们常说的业务价值和技术价值的权衡,其实精髓就在此,当然里面有些言论有些激烈,很多牢骚抱怨我们也有过,换个角度来想,也就释然了。这篇文章我看了很多遍,我喜欢看那些深刻的问题而不是个别敏感的字眼。所以推荐大家阅读也吸取有价值的思想,不要太拘泥于里面的个别表达方式。问题讨论的知乎链接为: https://www.zhihu.com/question/32039226/ ----------------------------------------------------------- 今年年初,到一家互联网公司实习,该公司是国内行业龙头。 不过技术和管理方面,却弱爆了。 那里的程序员,每天都在看邮件,查问题工单。 这些问题,多半是他们设计不当,造成的。 代码写的一团糟,全是复制粘贴,连作者都没改,大家普遍不写注释,也不格式化,代码歪歪扭扭。 一个项目里,httpclient竟然出现了四种。 一种是该公司研发部写的, 一种是老版本的开源项目, 一种是新版本的开源项目, 还有一种是开发人员造的轮子。 打接口请求响应日志,竟然不知道用拦截器。 打错误日志竟然不打上下文信息,每个人一种日志风格,千奇百怪。 许多重要的中间流程,居然不打日志。 idea、eclipse

问题 I am trying to send some message to mft server via REST API, and I'm using MultipartHttpEntityBuilder to build the message but along with original message some unwanted header and additional data is also getting attached. I found similar issue MultipartEntityBuilder: Omit Content-Type and Content-Transfer, but it was helpful. My Code snippet : HttpPut putRequest = new HttpPut(MFTSERVER_REST_LINK); MultipartEntityBuilder builder = MultipartEntityBuilder.create().setMode(HttpMultipartMode

springboot~openfeign从JSON文件读取数据

邮差的信 提交于 2021-02-09 03:38:53
对openfeign不清楚的同学可以先看我这篇文章: springboot~openfeign从此和httpClient说再见 对于openfeign来说,帮助我们解决了服务端调用服务端的问题,你不需要关心服务端的URI,只需要知道它在eureka里的服务名称即可,同时你与服务端确定了服务方法的参数和返回值之后,我们可以在单元测试时mock这些服务端方法即可,真正做到了单元测试,而不需要与外界资源进行交互。 今天主要说一下在openfeign里读取JSON文件的问题,我们将测试所需要的数据存储到文件里,在修改时关注点比较单纯。 JSON帮助类,主要使用了objectMapper这个对象 /** * 将json转换为对象. * * @param path 文件路径 */ public <T> T fromJson(String path, Class<T> cls) { try { return objectMapper.readValue( this .fromResource(path, Charsets.UTF_8), cls); } catch (Exception e) { throw new IllegalStateException("读取json失败:" + path, e); } } /** * 将json数组转换为对象列表. * * @param path

(Flutter) HTTPClient Invalid argument(s): No host specified in URI

问题 Currently working on a little app that allows users to view a database stored on Heroku, however I am running into the aforementioned issue when using the database's URL: ".herokuapp.com/api/". var client = createHttpClient(); var response = await client.read('<example>.herokuapp.com/api/<data>'); List data = JSON.decode(response); Heroku doesn't seem to use HTTP(S) nor www, the latter of which I believe to be the issue. Does anyone know how I can bypass or resolve this issue? 回答1: I know
