示例1: baseUrl
// baseUrl gets the base url active for the datastore service
// defaults to "https://www.googleapis.com/datastore/v1beta2/datasets/" if none was specified
func baseUrl(ctx context.Context) string {
v := ctx.Value(ContextKey("base_url"))
if v == nil {
return "https://www.googleapis.com/datastore/v1beta2/datasets/"
} else {
return v.(string)
}
}示例2: contextClient
func contextClient(ctx context.Context) (*http.Client, error) {
for _, fn := range contextClientFuncs {
c, err := fn(ctx)
if err != nil {
return nil, err
}
if c != nil {
return c, nil
}
}
if hc, ok := ctx.Value(HTTPClient).(*http.Client); ok {
return hc, nil
}
return http.DefaultClient, nil
}示例3: FromContext
// FromContext returns the MD in ctx if it exists.
func FromContext(ctx context.Context) (md MD, ok bool) {
md, ok = ctx.Value(mdKey{}).(MD)
return
}示例4: FromContext
// FromContext returns the Trace bound to the context, if any.
func FromContext(ctx context.Context) (tr Trace, ok bool) {
tr, ok = ctx.Value(contextKey).(Trace)
return
}示例5: ctxNamespace
// ctxNamespace returns the active namespace for a context.
// It defaults to "" if no namespace was specified.
func ctxNamespace(ctx context.Context) string {
v, _ := ctx.Value(nsKey{}).(string)
return v
}示例6: StreamFromContext
// StreamFromContext returns the stream saved in ctx.
func StreamFromContext(ctx context.Context) (s *Stream, ok bool) {
s, ok = ctx.Value(streamKey).(*Stream)
return
}示例7: FromContext
// FromContext returns the authInfo in ctx if it exists.
func FromContext(ctx context.Context) (authInfo AuthInfo, ok bool) {
authInfo, ok = ctx.Value(authInfoKey{}).(AuthInfo)
return
}示例8: cc
// cc returns the internal *cloudContext (cc) state for a context.Context.
// It panics if the user did it wrong.
func cc(ctx context.Context) *cloudContext {
if c, ok := ctx.Value(contextKey{}).(*cloudContext); ok {
return c
}
panic("invalid context.Context type; it should be created with cloud.NewContext")
}
