API Blueprint的安装

本文主要是介绍API Blueprint的安装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

什么是API Blueprint

API Blueprint 是一套基于 markdown 的 API 描述语言规范,API Blueprint 配套工具可以生成对应的HTML文档进行查看，方便生成离线文件保存，也便于对文件的查看

API Blueprint的工具

Aglio

aglioAglio是一种将API文件转换为HTML的工具。Aglio是惊人的，它非常快，默认情况下有一个很好的设计，并且可以通过自定义主题进行扩展。

Drafter

Drafter是由定义API Blueprint规范的Apiary制定的。您指定一个API Blueprint文件，然后Drafter将其转换为JSON对象。然后可以将此JSON对象提供给各种可解析API Blueprint JSON的工具。

Httpsnippet

Mashape提供的httpsnippet是一款非常棒的工具，它会采用HAR文件并为各种语言生成代码片段。

API Blueprint生成文件的流程图

API Blueprint工具 Aglio的安装

安装过程：

准备

在Visual Studio Code中安装API Blueprint
1、nodeJs环境的安装，npm的安装，Python的安装，并在Visual Studio Code的用户设置中设置Python的安装路径；
2.安装Aglio
执行命令：

npm install -g aglio

产生报错信息：

网上提供解决方案：

npm install -global -production windows-build-tools

通过执行该命令，发现主要是安装Python,本人已直接本地安装过Python，并设置过环境变量，并在VIsual Studio Code中设置”python.pythonPath”为本地安装路径

最终通过仔细查找报错信息发现是因为未安装C++编译环境，最后安装了一个 Visual Studio Community 2017，并安装了Microsoft Visual C++ Redistributable for Visual Studio 2017；

上述两文件下载路径均在：
https://www.visualstudio.com/zh-hans/downloads/?rr=http%3A%2F%2Flandinghub.visualstudio.com%2Fvisual-cpp-build-tools

安装后在执行npm install -g aglio，执行过程中需注意若安装了360可能会拦截权限更改，所有点击允许，最终安装成功。

Aglio的使用

foo.md编写的源文件；
bar.html是输出的HTML文件；
进入foo.md文件所在路径，执行命令：

aglio -i foo.md -o bar.html

输出文件bar.html在foo.md文件所在文件夹中；
