Question

我尝试实现此示例以比较值：

error = system_errors[response_code]
    raise error[:error_class].constantize, error[:error_message]

@system_errors = {100 => { error_class: 'SystemError', error_message = 'A general system error occured.'},
                    101 => { error_class: 'MaintenanceError', error_message = 'System is undergoing maintenance, request could not behandled.'},
                    110 => { error_class: 'AuthenticationError', error_message = 'Login failed. Check your API credentials.'},
                    120 => { error_class: 'ConfigurationError', error_message = 'Configuration error occured, e.g. terminal not configured properly. Check terminal settings.'},
                    200 => { error_class: 'CommunicationError', error_message = 'Communication with issuer failed, please contact support.'},
                    210 => { error_class: 'ConnectionError', error_message = 'Connection to issuer could not be established, please contact support.'},
                    220 => { error_class: 'AccountError', error_message = 'Issuer account data invalid, please contact support.'},
                    220 => { error_class: 'AccountError', error_message = 'Descption: Issuer account data invalid, please contact support.'},
                    230 => { error_class: 'TimeoutError', error_message = 'Issuer does not respond within given timeframe - please reconcile'}}

但是当我运行代码时，我收到了这个错误：

syntax error, unexpected '}', expecting => (SyntaxError)
...general system error occured.'},
...                               ^
/Users/response.rb:34: syntax error, unexpected '}', expecting =>
... request could not behandled.'},
...                               ^
    /Users/response.rb:41: syntax error, unexpected '}', expecting =>
... timeframe - please reconcile'}}
...                               ^
/Users/response.rb:45: class definition in method body
    /response.rb:80: syntax error, unexpected end-of-input, expecting keyword_end
    from /Users/.rvm/rubies/ruby-2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:55:in `require'

实现此代码的正确方法是什么？基本上我想将哈希值中的值与哈希值进行比较。

Answer 1

将所有=替换为哈希内的:。

@system_errors = {100 => { error_class: 'SystemError', error_message: 'A general system error occured.'},
                101 => { error_class: 'MaintenanceError', error_message: 'System is undergoing maintenance, request could not behandled.'},
                110 => { error_class: 'AuthenticationError', error_message: 'Login failed. Check your API credentials.'},
                120 => { error_class: 'ConfigurationError', error_message: 'Configuration error occured, e.g. terminal not configured properly. Check terminal settings.'},
                200 => { error_class: 'CommunicationError', error_message: 'Communication with issuer failed, please contact support.'},
                210 => { error_class: 'ConnectionError', error_message: 'Connection to issuer could not be established, please contact support.'},
                220 => { error_class: 'AccountError', error_message: 'Issuer account data invalid, please contact support.'},
                220 => { error_class: 'AccountError', error_message: 'Descption: Issuer account data invalid, please contact support.'},
                230 => { error_class: 'TimeoutError', error_message: 'Issuer does not respond within given timeframe - please reconcile'}}

Answer 2

错误：error_message = '...'

必须为error_message: '...'

@system_errors = {100 => { error_class: 'SystemError', error_message: 'A general system error occured.'},
                101 => { error_class: 'MaintenanceError', error_message: 'System is undergoing maintenance, request could not behandled.'},
                110 => { error_class: 'AuthenticationError', error_message: 'Login failed. Check your API credentials.'},
                120 => { error_class: 'ConfigurationError', error_message: 'Configuration error occured, e.g. terminal not configured properly. Check terminal settings.'},
                200 => { error_class: 'CommunicationError', error_message: 'Communication with issuer failed, please contact support.'},
                210 => { error_class: 'ConnectionError', error_message : 'Connection to issuer could not be established, please contact support.'},
                220 => { error_class: 'AccountError', error_message: 'Issuer account data invalid, please contact support.'},
                220 => { error_class: 'AccountError', error_message: 'Descption: Issuer account data invalid, please contact support.'},
                230 => { error_class: 'TimeoutError', error_message: 'Issuer does not respond within given timeframe - please reconcile'}}
