apache camel - Dynamic HTTP URI with recipientList returns 404 on the second call -
i have 2 step camel route workflow - both steps make post call same host, url , body different. first call returns part of url second call.
here code:
// register converter different request types getcontext().gettypeconverterregistry().addtypeconverters(new requestconverter()); from("direct:two-step-flow") .setheader("paramid", body().method("getparamid") .setheader("url", "http://localhost:8080/api/${header.paramid} .convertbodyto(step1request.class) .to("direct:call-remote-service") .convertbodyto(step2request.class) // converter sets newparamfromresponse .setheader("url", "http://localhost:8080/api/${header.paramid}/${body.newparamfromresponse} .to("direct:call-remote-service") .end(); from("direct:call-remote-service") .marshal().json(jsonlibrary.jackson) .recipientlist(header("url")) .unmarshal().json(jsonlibrary.jackson, genericresponse.class) .end(); first step works fine, http flow
httpclient.wire.header - >> "post /api/p1 http/1.1[\r][\n]" httpclient.wire.content - >> "{"amount":1.22,"reason":"some reason","relation-id":"12345"}" httpclient.wire.header - << "http/1.1 200 ok[\r][\n]" httpclient.wire.header - << "http/1.1 200 ok[\r][\n]" httpclient.wire.header - << "content-type: application/json[\r][\n]" httpclient.wire.header - << "transfer-encoding: chunked[\r][\n]" httpclient.wire.header - << "server: jetty(9.3.11.v20160721)[\r][\n]" httpclient.wire.header - << "[\r][\n]" org.apache.camel.component.http.httpproducer - http responsecode: 200 second step fails http 404
httpclient.wire.header - >> "post /api/p1/id1 http/1.1[\r][\n]" httpclient.wire.content - >> "{"action":"confirm","reason":"reason confirm","relation-id":"12345"}" org.apache.camel.component.http.httpproducer - http responsecode: 404 httpclient.wire.content - << "<html>[\n]" httpclient.wire.content - << "<head>[\n]" httpclient.wire.content - << "<meta http-equiv="content-type" content="text/html;charset=iso-8859-1"/>[\n]" httpclient.wire.content - << "<title>error 404 </title>[\n]" httpclient.wire.content - << "</head>[\n]" httpclient.wire.content - << "<body>[\n]" httpclient.wire.content - << "<h2>http error: 404</h2>[\n]" httpclient.wire.content - << "<p>problem accessing /api/p1/id1. reason:[\n]" httpclient.wire.content - << "<pre> not found</pre></p>[\n]" httpclient.wire.content - << "<hr /><a href="http://eclipse.org /jetty">powered jetty:// 9.3.11.v20160721</a><hr/>[\n]" httpclient.wire.content - << "</body>[\n]" httpclient.wire.content - << "</html>[\n]" the same post works curl:
curl 'http://localhost:8080/api/p1/id1' -i -x post -h 'accept:application/json' -h 'content-type: application/json' -d '{ "action" : "confirm", "relation-id" : "12345", "reason" : "reason confirm" }' http/1.1 200 ok content-type: application/json transfer-encoding: chunked server: jetty(9.3.11.v20160721) i might misusing .recipentlist, appreciated.
thanks
maybe http response headers picked , used 2nd call. therefore try removing http headers between 2 calls: http://camel.apache.org/how-to-remove-the-http-protocol-headers-in-the-camel-message.html
add
.removeheaders("camelhttp*") before call route recipient list
.to("direct:call-remote-service")
