调用阿里云身份证识别接口（使用appcode方式）

1，创建maven工程，导入依赖（当然，普通java工程也ok）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>image-orc</groupId><artifactId>lcm.test.aliyun.ORC</artifactId><version>0.0.1-SNAPSHOT</version><repositories><repository><id>nexus</id><name>Team Nexus Repository</name><url>http://maven.aliyun.com/nexus/content/groups/public</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></repository></repositories><dependencies><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.15</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.2.1</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpcore</artifactId><version>4.2.1</version></dependency><dependency><groupId>commons-lang</groupId><artifactId>commons-lang</artifactId><version>2.6</version></dependency><dependency><groupId>org.eclipse.jetty</groupId><artifactId>jetty-util</artifactId><version>9.3.7.v20160115</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.5</version><scope>test</scope></dependency><dependency><groupId>com.vdurmont</groupId><artifactId>emoji-Java</artifactId><version>3.1.3</version></dependency></dependencies></project>

2，开发代码（直接去阿里官网复制的案例）

httpUtils忘了

最后别忘了导入 org.json的jar包，当时应没有找到maven坐标，所以直接放进去了，哈哈
