本篇文章主要讲解如何在 Docker 中进行 Go 单元测试，依赖 Docker 和 Go Modules。 为什么是 Docker 在 Docker 之前我们往往需要在 Jenkins 服务器上配置不同的 Go 版本以及针对每个项目配置 GOPATH，项目之间的隔离性差，经常出现基础库版本冲突的问题。 有了 Docker，我们可以在不同容器中运行单元测试，该测试不局限不同项目，甚至可以是同一项目不同分支。 所以在测试隔离性和项目测试并发度上都有很大提升，而且测试结束后，环境清理也简单许多。 为什么是 Go Modules Go Modules 作为官方默认的包管理工具，基本解决了 Go 长期存在的包管理问题，它为我们的项目管理带来很多好处： 自动解析和添加依赖 签名验证 依赖缓存 支持相对...阅读全文

概述 首先同步下项目概况： 上篇文章分享了，路由中间件 - Jaeger 链路追踪（理论篇），这篇文章咱们接着分享：路由中间件 - Jaeger 链路追踪（实战篇）。 这篇文章，确实让大家久等了，主要是里面有一些技术点都是刚刚研究的，没有存货。 先看下咱们要实现的东西： API 调用了 5 个服务，其中 4 个 gRPC 服务，1 个 HTTP 服务，服务与服务之间又相互调用： Speak 服务，又调用了 Listen 服务 和 Sing 服务。 Read 服务，又调用了 Listen 服务 和 Sing 服务。 Write 服务，又调用了 Listen 服务 和 Sing 服务。 咱们要实现的就是查看 API 调用的链路。 关于一些理论的东西，大家可以去看看上篇文章或查阅一些资料，这篇文章...阅读全文

文链接：Go Modules 详解 Go 1.11 和 Go 1.12 包含了初步的 Go Modules 支持，且计划在 2019 年 8 月发布的 Go 1.13 会在所有开发过程中默认使用 Go Modules。 Go Modules 是为了提升使用其他开发者代码，即添加依赖项（模块、包）时的体验，也是为了让代码的正确性、安全性得到保障。并且 Go Modules 可以使用 GOPROXY 环境变量来解决中国大陆无法使用 go get 的问题。 所以学习跟 Go Modules 有关的知识是很有必要的。 模式 Go Modules 在 Go 1.11 及 Go 1.12 中有三个模式，根据环境变量 GO111MODULE 定义： 默认模式（未设置该环境变量或 GO111MODULE=a...阅读全文

回顾 上一节我们用Gin框架快速搭建了一个GET请求的接口，今天来学习路由和参数的获取。 请求动词 熟悉RESTful的同学应该知道，RESTful是网络应用程序的一种设计风格和开发方式，每一个URI代表一种资源，客户端通过POST、DELETE、PUT、GET四种请求方式来对资源做增删改查的操作。 同样的，Gin框架给我们提供的除这4种动词外，还有PATCH、OPTION、HEAD等，详细内容可以查看rentergroup.go文件的IRoutes接口。 type IRoutes interface { Use(...HandlerFunc) IRoutes Handle(string, string, ...HandlerFunc) IRoutes Any(string, ...Hand...阅读全文

Gin是什么？ Gin是Go语言编写的web框架，具备中间件、崩溃处理、JSON验证、内置渲染等多种功能。 准备工作 本系列演示所有代码都在Github中，感兴趣的同学可以自行查阅，欢迎大家一起完善。 https://github.com/pingyeaa/golang-examples/tree/master/gin 没有安装配置Go语言环境的同学请先自行安装，这里不再赘述。首先，我们来创建工作目录gin。 mkdir gin && cd gin 然后用go mod命令初始化项目，go mod是Go语言的包管理工具，官方推荐使用，有了它就不再受GOPATH的限制，可以在任何目录初始化项目。 go mod init gin 接下来安装gin库。 go get -u github.com/gi...阅读全文
