是否存在 PhantomJS 中所有错误代码的列表？
Does a list of all error codes in PhantomJS exist?
我在 Windows 7 上使用 PhantomJS V 2.1。根据 settings.resourceTimeout，当页面请求的资源超时时调用 onResourceTimeout 回调。回调的唯一参数是请求元数据对象。
请求元数据对象包含额外的错误相关属性：
errorCode:错误的错误代码errorString: 错误信息
是否存在描述所有 errorCode/errorString 的列表？
PhantomJS 2.1 使用 QT 5.5，您可能遇到的错误来自 QNetworkReply (link).
这是完整列表 (source)：
Constant Value Description
QNetworkReply::ConnectionRefusedError 1 the remote server refused the connection (the server is not accepting requests)
QNetworkReply::RemoteHostClosedError 2 the remote server closed the connection prematurely, before the entire reply was received and processed
QNetworkReply::HostNotFoundError 3 the remote host name was not found (invalid hostname)
QNetworkReply::TimeoutError 4 the connection to the remote server timed out
QNetworkReply::OperationCanceledError 5 the operation was canceled via calls to abort() or close() before it was finished.
QNetworkReply::SslHandshakeFailedError 6 the SSL/TLS handshake failed and the encrypted channel could not be established. The sslErrors() signal should have been emitted.
QNetworkReply::TemporaryNetworkFailureError 7 the connection was broken due to disconnection from the network, however the system has initiated roaming to another access point. The request should be resubmitted and will be processed as soon as the connection is re-established.
QNetworkReply::NetworkSessionFailedError 8 the connection was broken due to disconnection from the network or failure to start the network.
QNetworkReply::BackgroundRequestNotAllowedError 9 the background request is not currently allowed due to platform policy.
QNetworkReply::ProxyConnectionRefusedError 101 the connection to the proxy server was refused (the proxy server is not accepting requests)
QNetworkReply::ProxyConnectionClosedError 102 the proxy server closed the connection prematurely, before the entire reply was received and processed
QNetworkReply::ProxyNotFoundError 103 the proxy host name was not found (invalid proxy hostname)
QNetworkReply::ProxyTimeoutError 104 the connection to the proxy timed out or the proxy did not reply in time to the request sent
QNetworkReply::ProxyAuthenticationRequiredError 105 the proxy requires authentication in order to honour the request but did not accept any credentials offered (if any)
QNetworkReply::ContentAccessDenied 201 the access to the remote content was denied (similar to HTTP error 401)
QNetworkReply::ContentOperationNotPermittedError 202 the operation requested on the remote content is not permitted
QNetworkReply::ContentNotFoundError 203 the remote content was not found at the server (similar to HTTP error 404)
QNetworkReply::AuthenticationRequiredError 204 the remote server requires authentication to serve the content but the credentials provided were not accepted (if any)
QNetworkReply::ContentReSendError 205 the request needed to be sent again, but this failed for example because the upload data could not be read a second time.
QNetworkReply::ContentConflictError 206 the request could not be completed due to a conflict with the current state of the resource.
QNetworkReply::ContentGoneError 207 the requested resource is no longer available at the server.
QNetworkReply::InternalServerError 401 the server encountered an unexpected condition which prevented it from fulfilling the request.
QNetworkReply::OperationNotImplementedError 402 the server does not support the functionality required to fulfill the request.
QNetworkReply::ServiceUnavailableError 403 the server is unable to handle the request at this time.
QNetworkReply::ProtocolUnknownError 301 the Network Access API cannot honor the request because the protocol is not known
QNetworkReply::ProtocolInvalidOperationError 302 the requested operation is invalid for this protocol
QNetworkReply::UnknownNetworkError 99 an unknown network-related error was detected
QNetworkReply::UnknownProxyError 199 an unknown proxy-related error was detected
QNetworkReply::UnknownContentError 299 an unknown error related to the remote content was detected
QNetworkReply::ProtocolFailure 399 a breakdown in protocol was detected (parsing error, invalid or unexpected responses, etc.)
QNetworkReply::UnknownServerError 499 an unknown error related to the server response was detected
在源代码中可以找到额外的错误代码：
408 Network timeout on resource.
