var CreateFileCacheDirFailed = berror.DefineCode(4002009, moduleName, "CreateFileCacheDirFailed", `
|

Beego failed to create file cache directory. There are two cases:
|
||||
1. You pass invalid CachePath parameter. Please check your input.

var ReadFileCacheContentFailed = berror.DefineCode(4002011, moduleName, "ReadFileCacheContentFailed", `
|
||||
Usually you won't got this error. It means that Beego cannot read the data from the file.
|
||||

So when you query a key which may be expired, you may got this code, or KeyNotExist.

var MemCacheCurdFailed = berror.DefineCode(5002002, moduleName, "MemCacheError", `
|
||||
When you want to get, put, delete key-value from remote memcache servers, you may get error:
|
||||
1. You pass invalid servers address, so Beego could not connect to remote server;
|
||||
2. The servers address is correct, but there is some net issue. Typically there is some firewalls between application and memcache server;
|
||||
3. Key is invalid. The key's length should be less than 250 and must not contains special characters;
|
||||
4. The response from memcache server is invalid;

var RedisCacheCurdFailed = berror.DefineCode(5002003, moduleName, "RedisCacheCurdFailed", `
|

When Beego uses client to send request to redis server, it failed.
|
||||
1. The server addresses is invalid;
|
||||
2. Network issue, firewall issue or network is unstable;

3. Client failed to manage connection. In extreme cases, Beego's redis client didn't maintain connections correctly, for example, Beego try to send request via closed connection;
