Functions

func Bool 

func Bool(value bool) *bool

Bool returns a pointer to the provided bool

func CloseBodyIfValid 

func CloseBodyIfValid(httpResponse *http.Response)

CloseBodyIfValid closes the body of an http response if the response and the body are valid

func Debug 

func Debug(v ...interface{})

Debug logs v if debug mode is set

func Debugf 

func Debugf(format string, v ...interface{})

Debugf logs v with the provided format if debug mode is set

func Debugln 

func Debugln(v ...interface{})

Debugln logs v appending a new line if debug mode is set

func Float32 

func Float32(value float32) *float32

Float32 returns a pointer to the provided float32

func Float64 

func Float64(value float64) *float64

Float64 returns a pointer to the provided float64

func GetBodyHash 

func GetBodyHash(request *http.Request) (hashString string, err error)

GetBodyHash creates a base64 string from the hash of body the request

func HTTPRequestMarshaller 

func HTTPRequestMarshaller(requestStruct interface{}, httpRequest *http.Request) (err error)

HTTPRequestMarshaller marshals a structure to an http request using tag values in the struct The marshaller tag should like the following 

type A struct {
		 ANumber string `contributesTo="query" name="number"`
		 TheBody `contributesTo="body"`
}

where the contributesTo tag can be: header, path, query, body and the 'name' tag is the name of the value used in the http request(not applicable for path) If path is specified as part of the tag, the values are appened to the url path in the order they appear in the structure The current implementation only supports primitive types, except for the body tag, which needs a struct type. The body of a request will be marshaled using the tags of the structure

func IfDebug 

func IfDebug(fn func())

IfDebug executes closure if debug is enabled

func Int 

func Int(value int) *int

Int returns a pointer to the provided int

func IsConfigurationProviderValid

IsConfigurationProviderValid Tests all parts of the configuration provider do not return an error

func Logf 

func Logf(format string, v ...interface{})

Logf logs v with the provided format

func Logln 

func Logln(v ...interface{})

func MakeDefaultHTTPRequestWithTaggedStruct 

func MakeDefaultHTTPRequestWithTaggedStruct(method, path string, requestStruct interface{}) (httpRequest http.Request, err error)

func PointerString 

func PointerString(datastruct interface{}) (representation string)

PointerString prints the values of pointers in a struct Producing a human friendly string for an struct with pointers. useful when debugging the values of a struct

func PrivateKeyFromBytes 

func PrivateKeyFromBytes(pemData []byte, password *string) (key *rsa.PrivateKey, e error)

PrivateKeyFromBytes is a helper function that will produce a RSA private key from bytes.

func String 

func String(value string) *string

String returns a pointer to the provided string

func Uint 

func Uint(value uint) *uint

Uint returns a pointer to the provided uint

func UnmarshalResponse 

func UnmarshalResponse(httpResponse *http.Response, responseStruct interface{}) (err error)

UnmarshalResponse hydrates the fields of a struct with the values of a http response, guided by the field tags. The directive tag is "presentIn" and it can be either

  • "header": Will look for the header tagged as "name" in the headers of the struct and set it value to that
  • "body": It will try to marshal the body from a json string to a struct tagged with 'presentIn: "body"'.

Further this method will consume the body it should be safe to close it after this function Notice the current implementation only supports native types:int, strings, floats, bool as the field types

func UnmarshalResponseWithPolymorphicBody 

func UnmarshalResponseWithPolymorphicBody(httpResponse *http.Response, responseStruct interface{}, unmarshaler PolymorphicJSONUnmarshaler) (err error)

UnmarshalResponseWithPolymorphicBody similar to UnmarshalResponse but assumes the body of the response contains polymorphic json. This function will use the unmarshaler argument to unmarshal json content

func Version 

func Version() string

Version returns semantic version of the sdk
