Golang Context.Headers方法代码示例

// SetForwardedHeader adds a header to the current thrift context indicating
// that the call has been forwarded by another node in the ringpop ring.
// This header is used when a remote call is received to determine if forwarding
// checks needs to be applied. By not forwarding already forwarded calls we
// prevent unbound forwarding in the ring in case of memebership disagreement.
