示例1: stream

header := make(map[string]string)
if md, ok := metadata.FromContext(ctx); ok {
for k, v := range md {
header[k] = v
}
}
// set timeout in nanoseconds
header["timeout"] = fmt.Sprintf("%d", opts.RequestTimeout)
// set the content type for the request
header["x-content-type"] = req.ContentType()
md := gmetadata.New(header)
ctx = gmetadata.NewContext(ctx, md)
