Constants

const (
	Version = "0.5"

	// UserAgent is the header string used to identify this package.
	UserAgent = "google-api-go-client/" + Version
)

Variables

var WithDataWrapper = MarshalStyle(true)

var WithoutDataWrapper = MarshalStyle(false)

Functions

func Bool

func Bool(v bool) *bool

Bool is a helper routine that allocates a new bool value to store v and returns a pointer to it.

func CheckMediaResponse

func CheckMediaResponse(res *http.Response) error

CheckMediaResponse returns an error (of type *Error) if the response status code is not 2xx. Unlike CheckResponse it does not assume the body is a JSON error document.

func CheckResponse

func CheckResponse(res *http.Response) error

CheckResponse returns an error (of type *Error) if the response status code is not 2xx.

func CloseBody

func CloseBody(res *http.Response)

CloseBody is used to close res.Body. Prior to calling Close, it also tries to Read a small amount to see an EOF. Not seeing an EOF can prevent HTTP Transports from reusing connections.

func CombineFields

func CombineFields(s []Field) string

CombineFields combines fields into a single string.

func ConvertVariant

func ConvertVariant(v map[string]interface{}, dst interface{}) bool

ConvertVariant uses the JSON encoder/decoder to fill in the struct 'dst' with the fields found in variant 'v'. This is used to support "variant" APIs that can return one of a number of different types. It reports whether the conversion was successful.

func Expand

func Expand(u *url.URL, expansions map[string]string)

Expand subsitutes any {encoded} strings in the URL passed in using the map supplied.

This calls SetOpaque to avoid encoding of the parameters in the URL path.

func Float64

func Float64(v float64) *float64

Float64 is a helper routine that allocates a new float64 value to store v and returns a pointer to it.

func Int32

func Int32(v int32) *int32

Int32 is a helper routine that allocates a new int32 value to store v and returns a pointer to it.

func Int64

func Int64(v int64) *int64

Int64 is a helper routine that allocates a new int64 value to store v and returns a pointer to it.

func IsNotModified

func IsNotModified(err error) bool

IsNotModified reports whether err is the result of the server replying with http.StatusNotModified. Such error values are sometimes returned by "Do" methods on calls when If-None-Match is used.

func ResolveRelative

func ResolveRelative(basestr, relstr string) string

func SetOpaque

func SetOpaque(u *url.URL)

SetOpaque sets u.Opaque from u.Path such that HTTP requests to it don't alter any hex-escaped characters in u.Path.

func String

func String(v string) *string

String is a helper routine that allocates a new string value to store v and returns a pointer to it.

func Uint32

func Uint32(v uint32) *uint32

Uint32 is a helper routine that allocates a new uint32 value to store v and returns a pointer to it.

func Uint64

func Uint64(v uint64) *uint64

Uint64 is a helper routine that allocates a new uint64 value to store v and returns a pointer to it.

func VariantType

func VariantType(t map[string]interface{}) string

VariantType returns the type name of the given variant. If the map doesn't contain the named key or the value is not a []interface{}, "" is returned. This is used to support "variant" APIs that can return one of a number of different types.

Types

type ContentTyper

type ContentTyper interface {
	ContentType() string
}

ContentTyper is an interface for Readers which know (or would like to override) their Content-Type. If a media body doesn't implement ContentTyper, the type is sniffed from the content using http.DetectContentType.

type Error

type Error struct {
	// Code is the HTTP response status code and will always be populated.
	Code int `json:"code"`
	// Message is the server response message and is only populated when
	// explicitly referenced by the JSON server response.
	Message string `json:"message"`
	// Body is the raw response returned by the server.
	// It is often but not always JSON, depending on how the request fails.
	Body string
	// Header contains the response header fields from the server.
	Header http.Header

	Errors []ErrorItem
}

Error contains an error response from the server.

func (*Error) Error

func (e *Error) Error() string

type ErrorItem

type ErrorItem struct {
	// Reason is the typed error code. For example: "some_example".
	Reason string `json:"reason"`
	// Message is the human-readable description of the error.
	Message string `json:"message"`
}

ErrorItem is a detailed error code & message from the Google API frontend.

type Field

type Field string

A Field names a field to be retrieved with a partial response. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse

Partial responses can dramatically reduce the amount of data that must be sent to your application. In order to request partial responses, you can specify the full list of fields that your application needs by adding the Fields option to your request.

Field strings use camelCase with leading lower-case characters to identify fields within the response.

For example, if your response has a "NextPageToken" and a slice of "Items" with "Id" fields, you could request just those fields like this:

svc.Events.List().Fields("nextPageToken", "items/id").Do()

or if you were also interested in each Item's "Updated" field, you can combine them like this:

svc.Events.List().Fields("nextPageToken", "items(id,updated)").Do()

More information about field formatting can be found here: https://developers.google.com/+/api/#fields-syntax

Another way to find field names is through the Google API explorer: https://developers.google.com/apis-explorer/#p/

type Float64s

type Float64s []float64

Float64s is a slice of float64s that marshal as quoted strings in JSON.

func (Float64s) MarshalJSON

type MarshalStyle

type MarshalStyle bool

func (MarshalStyle) JSONReader

func (wrap MarshalStyle) JSONReader(v interface{}) (io.Reader, error)

type ProgressUpdater

type ProgressUpdater func(current, total int64)

ProgressUpdater is a function that is called upon every progress update of a resumable upload. This is the only part of a resumable upload (from googleapi) that is usable by the developer. The remaining usable pieces of resumable uploads is exposed in each auto-generated API.

type ResumableUpload

type ResumableUpload struct {
	Client *http.Client
	// URI is the resumable resource destination provided by the server after specifying "&uploadType=resumable".
	URI       string
	UserAgent string // User-Agent for header of the request
	// Media is the object being uploaded.
	Media io.ReaderAt
	// MediaType defines the media type, e.g. "image/jpeg".
	MediaType string
	// ContentLength is the full size of the object being uploaded.
	ContentLength int64

	// Callback is an optional function that will be periodically called with the cumulative number of bytes uploaded.
	Callback func(int64)
	// contains filtered or unexported fields
}

ResumableUpload is used by the generated APIs to provide resumable uploads. It is not used by developers directly.

func (*ResumableUpload) Progress

func (rx *ResumableUpload) Progress() int64

Progress returns the number of bytes uploaded at this point.

func (*ResumableUpload) Upload

func (rx *ResumableUpload) Upload(ctx context.Context) (*http.Response, error)

Upload starts the process of a resumable upload with a cancellable context. It retries indefinitely (with a pause of uploadPause between attempts) until cancelled. It is called from the auto-generated API code and is not visible to the user. rx is private to the auto-generated API code.

type ServerResponse

type ServerResponse struct {
	// HTTPStatusCode is the server's response status code.
	// When using a resource method's Do call, this will always be in the 2xx range.
	HTTPStatusCode int
	// Header contains the response header fields from the server.
	Header http.Header
}

ServerResponse is embedded in each Do response and provides the HTTP status code and header sent by the server.

type SizeReaderAt

type SizeReaderAt interface {
	io.ReaderAt
	Size() int64
}

A SizeReaderAt is a ReaderAt with a Size method. An io.SectionReader implements SizeReaderAt.
