httpclient-4.2.1-redhat-1.jar中文-英文对照文档.zip 中包含以下内容

1. 中文-英文对照文档：位于压缩包内的“文档”文件夹中
2. 说明文件：使用说明.txt、README.md
3. Maven依赖：httpclient-4.2.1-redhat-1.jar Maven依赖信息(可用于项目pom.xml).txt
4. Gradle依赖：httpclient-4.2.1-redhat-1.jar Gradle依赖信息(可用于项目build.gradle).txt
5. jar包下载地址：httpclient-4.2.1-redhat-1.jar下载地址(官方地址+国内镜像地址).txt
6. 源码下载地址：httpclient-4.2.1-redhat-1-sources.jar下载地址(官方地址+国内镜像地址).txt

使用方法

1. 解压 httpclient-4.2.1-redhat-1.jar中文-英文对照文档.zip，找到 解压后的文件夹>文档>index.html，双击index.html即可用浏览器打开查看。
2. 为了防止解压后路径太长导致浏览器无法打开，推荐在解压时选择“解压到当前文件夹”（放心，自带文件夹，文件不会散落一地）。
3. 有时，一套Java组件会有多个jar，所以在下载前，请仔细阅读本篇描述，以确保这就是你需要的文件。
