HTTP Transports

HTTP Transport to be used with the http client from go.

Environment based configuration

  • HTTP_TRANSPORT_DUMP default: "" (option values are comma separated)
    • Can contain a list of logging options:
      • request will log the complete request with headers human readable
      • response will log the complete response with headers human readable
      • request-hex will log the complete request with headers in HEX
      • response-hex will log the complete response with headers in HEX
      • body will enable logging of the body for hex and human readable outputs
    • Simple request header logging may look like this request,response
    • Full human readable logging may look like this request,response,body
    • Complete logging may look like this request,response,request-hex,response-hex,body
