企业微信机器人发送消息

一、可能需要的依赖
二、机器人地址号查看
三、效果展示
四、具体代码

一、可能需要的依赖

        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.3.5</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.9.3</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->

            <artifactId>jackson-annotations</artifactId>
            <version>2.9.3</version>
        </dependency>

        <dependency>

        </dependency>
        <dependency>
            <groupId>commons-lang</groupId>
            <artifactId>commons-lang</artifactId>
            <version>2.6</version>
        </dependency>

二、机器人地址号查看

新建一个群聊机器人，可以查看机器人的接口地址，不需要密钥和企业id号

三、效果展示

输如需要发送的消息

获取返回值

微信收到消息

四、具体代码

如果觉得不错就点个赞吧！！
