使用 POSTMAN 在 saiku 中命中查询 EXECUTE API 时出错

Question

I have API for execute the query [http://localhost:8080/saiku/rest/saiku/api/query/execute] 并且我将输入作为 application/json.

正文:

一旦我点击 API 就意味着我得到了一个错误，例如

SEVERE: Mapped exception to response: 500 (Internal Server Error)

但它在本地主机网络应用程序中工作正常，而不是在 POSTMAN

我的案例遇到了同样的问题，这已经解决了我的问题 1。http://localhost:8080/saiku/rest/saiku/username/query/queryname/， 2.http://localhost:8080/saiku/rest/saiku/api/query/execute/。当您调用 post man 时，两个查询名称必须相同。对于 api 2 queryname 值在输入中 Json（参数作为名称）.

使用 POSTMAN 在 saiku 中命中查询 EXECUTE API 时出错
