一、前言
微信接口调用验证最终需要用到的三个参数noncestr、timestamp、signature:
接下来将会给出获取这三个参数的详细代码
本文的环境eclipse + maven
本文使用到的技术httpclient、json字符串转map、sha1加密
二、需要用到的jar包
maven依赖的包有:
1、httpclient包依赖
<dependency> <groupid>org.apache.httpcomponents</groupid> <artifactid>httpcore</artifactid> <version>4.4.3</version> </dependency> <dependency> <groupid>org.apache.httpcomponents</groupid> <artifactid>httpclient</artifactid> <version>4.5.1</version> </dependency>
2、json转map相关包依赖
<dependency> <groupid>net.sf.json-lib</groupid> <artifactid>json-lib</artifactid> <version>2.4</version> <classifier>jdk15</classifier> </dependency> <dependency> <groupid>xom</groupid> <artifactid>xom</artifactid> <version>1.2.5</version> </dependency>
三、运行结果
四、详细代码
