【问题描述】：
很抱歉发布此信息，因为这对专家来说可能是一个简单的问题，但对我作为初学者来说，这是一个需要解决的重要问题。我创建了一个WSO2 DSS service，其中有一个名为MYSQL 的表数据源users(userid(auto_increment),first_name,last_name,password).
我为 GET、POST、PUT、DELETE 以及资源创建了特定的查询来满足这些请求。当我开始使用 cURL GET 和 DELETE 测试服务时，它正在工作，我能够检索和删除数据。但是，当我尝试插入（POST）和更新（PUT）数据时，我遇到了多个错误 如下图：
curl: (6) Could not resolve host: first_name curl: (6) Could not
resolve host: last_name curl: (6) Could not resolve host: password

这是我使用的 cURL 命令：
POST - curl -i -H "Authorization: Bearer f56ce778dee04274eba0eab3e9d7b324" -H "Accept: application/json" -X POST -d {"first_name":"chris","last_name":"paul","password":"cp3"} http://ip:port/SampleDSS/user/
PUT - curl -i -H "Authorization: Bearer f56ce778dee04274eba0eab3e9d7b324" -H "Accept: application/json" -X PUT -d {"userid":11,"first_name":"chris","last_name":"paul","password":"cp3"} http://ip:port/SampleDSS/user/
您能否指出我正在使用的cURL 命令或JSON 格式数据是否存在问题？
我们欢迎任何实质性的帮助。
非常感谢！
