type EndpointNotFoundError struct {
Partition string
Service string
Region string
// contains filtered or unexported fields

type EnumPartitions ¶

Use this interface with DefaultResolver and DecodeModels to get the list of Partitions.

▹ Example
type Options ¶
Options provide the configuration needed to direct how the endpoints will be resolved.
type Options struct { // DisableSSL forces the endpoint to be resolved as HTTP. // instead of HTTPS if the service supports it. DisableSSL bool // Sets the resolver to resolve the endpoint as a dualstack endpoint // for the service. If dualstack support for a service is not known and // StrictMatching is not enabled a dualstack endpoint for the service will // be returned. This endpoint may not be valid. If StrictMatching is // enabled only services that are known to support dualstack will return // dualstack endpoints. UseDualStack bool // Enables strict matching of services and regions resolved endpoints. // If the partition doesn't enumerate the exact service and region an // error will be returned. This option will prevent returning endpoints // that look valid, but may not resolve to any real endpoint. StrictMatching bool // Enables resolving a service endpoint based on the region provided if the // service does not exist. The service endpoint ID will be used as the service // domain name prefix. By default the endpoint resolver requires the service // to be known when resolving endpoints. // // If resolving an endpoint on the partition list the provided region will // be used to determine which partition's domain name pattern to the service // endpoint ID with. If both the service and region are unkonwn and resolving // the endpoint on partition list an UnknownEndpointError error will be returned. // // If resolving and endpoint on a partition specific resolver that partition's // domain name pattern will be used with the service endpoint ID. If both // region and service do not exist when resolving an endpoint on a specific // partition the partition's domain pattern will be used to combine the // endpoint and region together. // // This option is ignored if StrictMatching is enabled. ResolveUnknownService bool }
func (*Options) Set ¶
func (o *Options) Set(optFns ...func(*Options))
Set combines all of the option functions together.
type Partition ¶
A Partition provides the ability to enumerate the partition's regions and services.
type Partition struct {
// contains filtered or unexported fields
}
func AwsCnPartition ¶
func AwsCnPartition() Partition

func PartitionForRegion ¶
func PartitionForRegion(ps []Partition, regionID string) (Partition, bool)
PartitionForRegion returns the first partition which includes the region passed in. This includes both known regions and regions which match a pattern supported by the partition which may include regions that are not explicitly known by the partition. Use the Regions method of the returned Partition if explicit support is needed.
func (Partition) EndpointFor ¶
func (p Partition) EndpointFor(service, region string, opts ...func(*Options)) (ResolvedEndpoint, error)
EndpointFor attempts to resolve the endpoint based on service and region. See Options for information on configuring how the endpoint is resolved.
If the service cannot be found in the metadata the UnknownServiceError error will be returned. This validation will occur regardless if StrictMatching is enabled. To enable resolving unknown services set the "ResolveUnknownService" option to true. When StrictMatching is disabled this option allows the partition resolver to resolve a endpoint based on the service endpoint ID provided.
When resolving endpoints you can choose to enable StrictMatching. This will require the provided service and region to be known by the partition. If the endpoint cannot be strictly resolved an error will be returned. This mode is useful to ensure the endpoint resolved is valid. Without StrictMatching enabled the endpoint returned my look valid but may not work. StrictMatching requires the SDK to be updated if you want to take advantage of new regions and services expansions.
Errors that can be returned.
