This is the official Go SDK for Oracle Cloud Infrastructure
Installation
Refer to https://github.com/oracle/oci-go-sdk/blob/master/README.md#installing for installation instructions.
Configuration
Refer to https://github.com/oracle/oci-go-sdk/blob/master/README.md#configuring for configuration instructions.
Quickstart
The following example shows how to get started with the SDK. The example belows creates an identityClient
struct with the default configuration. It then utilizes the identityClient to list availability domains and prints
them out to stdout
import (
"context"
"fmt"
"github.com/oracle/oci-go-sdk/common"
"github.com/oracle/oci-go-sdk/identity"
)
func main() {
c, err := identity.NewIdentityClientWithConfigurationProvider(common.DefaultConfigProvider())
if err != nil {
fmt.Println("Error:", err)
return
}
// The OCID of the tenancy containing the compartment.
tenancyID, err := common.DefaultConfigProvider().TenancyOCID()
if err != nil {
fmt.Println("Error:", err)
return
}
request := identity.ListAvailabilityDomainsRequest{
CompartmentId: &tenancyID,
}
r, err := c.ListAvailabilityDomains(context.Background(), request)
if err != nil {
fmt.Println("Error:", err)
return
}
fmt.Printf("List of available domains: %v", r.Items)
return
}

Optional fields in the SDK
Optional fields are represented with the `mandatory:"false"` tag on input structs. The SDK will omit all optional fields that are nil when making requests.
In the case of enum-type fields, the SDK will omit fields whose value is an empty string.
Helper functions
The SDK uses pointers for primitive types in many input structs. To aid in the construction of such structs, the SDK provides
functions that return a pointer for a given value. For example:
// Given the struct
type CreateVcnDetails struct {
// Example: `172.16.0.0/16`
CidrBlock *string `mandatory:"true" json:"cidrBlock"`
CompartmentId *string `mandatory:"true" json:"compartmentId"`
DisplayName *string `mandatory:"false" json:"displayName"`
}
// We can use the helper functions to build the struct
details := core.CreateVcnDetails{
CidrBlock: common.String("172.16.0.0/16"),
CompartmentId: common.String("someOcid"),
DisplayName: common.String("myVcn"),
}
Signing custom requests
The SDK exposes a stand-alone signer that can be used to signing custom requests. Related code can be found here:
https://github.com/oracle/oci-go-sdk/blob/master/common/http_signer.go.
The example below shows how to create a default signer.
client := http.Client{}
var request http.Request
request = ... // some custom request
// Set the Date header
request.Header.Set("Date", time.Now().UTC().Format(http.TimeFormat))
// And a provider of cryptographic keys
provider := common.DefaultConfigProvider()
// Build the signer
signer := common.DefaultSigner(provider)
// Sign the request
signer.Sign(&request)
// Execute the request
client.Do(request)
The signer also allows more granular control on the headers used for signing. For example:
client := http.Client{}
var request http.Request
request = ... // some custom request
// Set the Date header
request.Header.Set("Date", time.Now().UTC().Format(http.TimeFormat))
// Mandatory headers to be used in the sign process
defaultGenericHeaders = []string{"date", "(request-target)", "host"}
// Optional headers
optionalHeaders = []string{"content-length", "content-type", "x-content-sha256"}
// A predicate that specifies when to use the optional signing headers
optionalHeadersPredicate := func (r *http.Request) bool {
return r.Method == http.MethodPost
}
// And a provider of cryptographic keys
provider := common.DefaultConfigProvider()
// Build the signer
signer := common.RequestSigner(provider, defaultGenericHeaders, optionalHeaders, optionalHeadersPredicate)
// Sign the request
signer.Sign(&request)
// Execute the request
c.Do(request)
For more information on the signing algorithm refer to: https://docs.us-phoenix-1.oraclecloud.com/Content/API/Concepts/signingrequests.htm
Polymorphic json requests and responses
Some operations accept or return polymorphic json objects. The SDK models such objects as interfaces. Further the SDK provides
structs that implement such interfaces. Thus, for all operations that expect interfaces as input, pass the struct in the SDK that satisfies
such interface. For example:
c, err := identity.NewIdentityClientWithConfigurationProvider(common.DefaultConfigProvider())
if err != nil {
panic(err)
}
// The CreateIdentityProviderRequest takes a CreateIdentityProviderDetails interface as input
rCreate := identity.CreateIdentityProviderRequest{}
// The CreateSaml2IdentityProviderDetails struct implements the CreateIdentityProviderDetails interface
details := identity.CreateSaml2IdentityProviderDetails{}
details.CompartmentId = common.String(getTenancyID())
details.Name = common.String("someName")
//... more setup if needed
// Use the above struct
rCreate.CreateIdentityProviderDetails = details
// Make the call
rspCreate, createErr := c.CreateIdentityProvider(context.Background(), rCreate)
In the case of a polymorphic response you can type assert the interface to the expected type. For example:
rRead := identity.GetIdentityProviderRequest{}
rRead.IdentityProviderId = common.String("aValidId")
response, err := c.GetIdentityProvider(context.Background(), rRead)
provider := response.IdentityProvider.(identity.Saml2IdentityProvider)
An example of polymorphic json request handling can be found here: https://github.com/oracle/oci-go-sdk/blob/master/example/example_core_test.go#L63
Pagination
When calling a list operation, the operation will retrieve a page of results. To retrieve more data, call the list operation again,
passing in the value of the most recent response's OpcNextPage as the value of Page in the next list operation call.
When there is no more data the OpcNextPage field will be nil. An example of pagination using this logic can be found here: https://github.com/oracle/oci-go-sdk/blob/master/example/example_core_test.go#L86
Logging and Debugging
The SDK has a built-in logging mechanism used internally. The internal logging logic is used to record the raw http
requests, responses and potential errors when (un)marshalling request and responses.
To expose debugging logs, set the environment variable "OCI_GO_SDK_DEBUG" to "1", or some other non empty string.
Forward Compatibility
Some response fields are enum-typed. In the future, individual services may return values not covered by existing enums
for that field. To address this possibility, every enum-type response field is a modeled as a type that supports any string.
Thus if a service returns a value that is not recognized by your version of the SDK, then the response field will be set to this value.
When individual services return a polymorphic json response not available as a concrete struct, the SDK will return an implementation that only satisfies
the interface modeling the polymorphic json response.
