spring cloud 问题记录（十五） Unauthorized grant type: authorization_code

在使用授权码的方式获取code的时候出现如下异常：

org.springframework.security.oauth2.common.exceptions.InvalidClientException: Unauthorized grant type: authorization_code
	at org.springframework.security.oauth2.provider.token.AbstractTokenGranter.validateGrantType(AbstractTokenGranter.java:82) ~[spring-security-oauth2-2.2.1.RELEASE.jar:na]

其实错误信息还是很明显的，就是client没有支持authorization_code的授权类型。

在数据库中最加上就行

重新发送授权请求就可以了
