Question

我使用的是WSO2 API Manager 1.6.0和BAM 2.4.0。

尝试收集统计信息时，我在BAM中收到此错误：

TID: [0] [BAM] [2014-02-13 10:46:17,841] ERROR {org.wso2.carbon.hadoop.hive.jdbc.storage.db.DBOperation} -  Failed to write data to database {org.wso2.carbon.hadoop.hive.jdbc.storage.db.DBOperation}

我意识到我可以简单地允许consumerkey允许空值...但是更新WSo2定义的DDL似乎是一个坏主意。

我认为这可能与API管理器在尝试使用“tryit”功能时遇到的问题有关，但未正确接收密钥。我会收到错误：

TID: [0] [AM] [2014-02-13 14:25:02,513] ERROR {org.wso2.carbon.apimgt.gateway.handlers.security.APIAuthenticationHandler} -  API authentication failure {org.wso2.carbon.apimgt.gateway.handlers.security.APIAuthenticationHandler}
org.wso2.carbon.apimgt.gateway.handlers.security.APISecurityException: Access failure for API: /APIPhoneVerify, version: 2.0.0 with key: null

我之前发布了'tryit'问题，并被告知我根据http://docs.wso2.org/display/AM160/Adding+Documentation+Using+Swagger更新了我的配置，但我没有帮助。

有关如何清除BAM错误的任何想法？和/或修复'tryit'功能？

Answer 1

尝试使用try it功能访问API时，似乎会发生NULL值插入。这将发送一个飞行前OPTION请求，以查看是否允许浏览器访问该资源，并且此请求不会发送访问令牌。由于它是通过访问令牌，导出了消费者密钥，当OPTIONS请求通过网关时，将无法找到与之关联的消费者密钥 - 因此空值将被推送到BAM。这似乎是一个错误，您可以在https://wso2.org/jira/browse/APIMANAGER报告此问题。

但是，NULL值插入对调用API没有任何影响。根据提供的错误，从tryit发送的请求（实际请求，而不是在飞行前的请求）似乎没有发送访问令牌。

WSO2 APIM和BAM - 如何解决空值问题？
