我想在iOS上订阅一个gcm主题。
GCMPubSub.sharedInstance().subscribeWithToken(registrationId, topic: "/topics/mytopic", options: nil) { error in
print(error.localizedDescription)
}
操作无法完成。(com.google.gcm错误3004。)
我无法在任何地方找到此错误代码的文档。我还阅读了定义错误的源代码,它看起来像是这样:
typedef NS_ENUM(NSUInteger, GCMServiceErrorCode) {
/**
* HTTP errors.
*/
// InvalidRequest -- Some parameters of the request were invalid.
kGCMServiceErrorCodeInvalidRequest = 0,
// Auth Error -- GCM couldn't validate request from this client.
kGCMServiceErrorCodeAuthentication = 1,
// NoAccess -- InstanceID service cannot be accessed.
kGCMServiceErrorCodeNoAccess = 2,
// Timeout -- Request to InstanceID backend timed out.
kGCMServiceErrorCodeTimeout = 3,
// Network -- No network available to reach the servers.
kGCMServiceErrorCodeNetwork = 4,
// OperationInProgress -- Another similar operation in progress,
// bailing this one.
kGCMServiceErrorCodeOperationInProgress = 5,
// Unknown error.
kGCMServiceErrorCodeUnknown = 7,
/**
* Upstream Send errors
*/
// Upstream send not available (e.g. network issues)
kGCMServiceErrorCodeUpstreamServiceNotAvailable = 1001,
// Invalid send parameters.
kGCMServiceErrorCodeInvalidParameters = 1002,
// Invalid missing to.
kGCMServiceErrorCodeMissingTo = 1003,
// GCM could not cache the message for sending.
kGCMServiceErrorSave = 1004,
// Message size exceeded (size > 4KB).
kGCMServiceErrorSizeExceeded = 1005,
/**
* GCM Connect errors.
*/
// GCM already connected with the client.
kGCMServiceErrorCodeAlreadyConnected = 2001,
/**
* PubSub errors.
*/
// Topic already subscribed to.
kGCMServiceErrorCodePubSubAlreadySubscribed = 3001,
// Topic already unsubscribed from.
kGCMServiceErrorCodePubSubAlreadyUnsubscribed = 3002,
// Invalid topic name, does not match the topic regex "/topics/[a-zA-Z0-9-_.~%]+"
kGCMServiceErrorCodePubSubInvalidTopic = 3003,
};
错误代码结束于3003!
GCMService
和GGLInstanceID
