Question

에서 수행하지 않습니다

throw new Error('The databasenumber was wrong, or you didn\'t bind one.' + process.env.VCAP_SERVICES + " === " + process.env.VCAP_SERVICES["mysql-5.1"]); 

이 순간에 출력하는 것입니다 :

node.js:201 
    throw e; // process.nextTick error, or 'error' event on first tick 
     ^
Error: The databasenumber was wrong, or you didn't bind one.{"mysql-5.1":[{"name":"squarific-data","label":"mysql-5.1","plan":"free","tags":["mysql","mysql-5.1","relational","mysql-5.1","mysql"],"credentials":{"name":"d3d440f0f5eef44ceb9c5e27a94666b58","hostname":"eu01-user01.cbxizyg0fwcn.eu-west-1.rds.amazonaws.com","host":"eu01-user01.cbxizyg0fwcn.eu-west-1.rds.amazonaws.com","port":3306,"user":"uzb6UEDnb5huk","username":"uzb6UEDnb5huk","password":"***"}}]} === undefined

이 당연히은해야하지만 :

node.js:201 
    throw e; // process.nextTick error, or 'error' event on first tick 
     ^
Error: The databasenumber was wrong, or you didn't bind one.{"mysql-5.1":[{"name":"squarific-data","label":"mysql-5.1","plan":"free","tags":["mysql","mysql-5.1","relational","mysql-5.1","mysql"],"credentials":{"name":"d3d440f0f5eef44ceb9c5e27a94666b58","hostname":"eu01-user01.cbxizyg0fwcn.eu-west-1.rds.amazonaws.com","host":"eu01-user01.cbxizyg0fwcn.eu-west-1.rds.amazonaws.com","port":3306,"user":"uzb6UEDnb5huk","username":"uzb6UEDnb5huk","password":"***"}}]} === [{"name":"squarific-data","label":"mysql-5.1","plan":"free","tags":["mysql","mysql-5.1","relational","mysql-5.1","mysql"],"credentials":{"name":"d3d440f0f5eef44ceb9c5e27a94666b58","hostname":"eu01-user01.cbxizyg0fwcn.eu-west-1.rds.amazonaws.com","host":"eu01-user01.cbxizyg0fwcn.eu-west-1.rds.amazonaws.com","port":3306,"user":"uzb6UEDnb5huk","username":"uzb6UEDnb5huk","password":"***"}}]

당신이 명확하게 [ "mysql을 - 5.1"] 사실입니다 볼 수있는 정의되지 안

n 어레이. 왜 내가이 이상한 행동을하는지 전혀 모르겠다.

서비스 변수는 appfog에 의해 객체 대신 JSON 문자열로 전달됩니다.
