示例1: 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2: 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3: 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")
}示例4: 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5: 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6: FromContext
// FromContext returns the peer information in ctx if it exists.
func FromContext(ctx context.Context) (p *Peer, ok bool) {
p, ok = ctx.Value(peerKey{}).(*Peer)
return
}
