I am trying to use an API to proxy a back end REST service. My
API deceleration is given below. I have avoided using any url-pattern or
template in order to define a "pass thru" API.
<api name="StockQuoteAPI" context="/stockquote">
<resource methods="POST GET">
<inSequence>
<send>
<endpoint>
<address uri="
http://localhost:9768/services/MobileDirectoryService";
format="rest"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<send/>
</outSequence>
</resource>
</api>
I invoked the API using the curl option, curl -X GET
http://localhost:8283/stockquote/mobile/bbb but ended up with the error[1]
in the back end. The request message trace is given below.
client to ESB:
GET /stockquote/mobile/bbb HTTP/1.1
User-Agent: curl/7.21.7 (x86_64-redhat-linux-gnu) libcurl/7.21.7 NSS/
3.12.10.0 zlib/1.2.5 libidn/1.22 libssh2/1.2.7
Host: 127.0.0.1:8283
Accept: */*
ESB to back end rest service:
POST /services/MobileDirectoryService/stockquote/mobile/bbb HTTP/1.1
Content-Type: application/xml; charset=UTF-8
Accept: */*
Transfer-Encoding: chunked
Host: 127.0.0.1:9768
Connection: Keep-Alive
User-Agent: Synapse-HttpComponents-NIO
It seems problem occurs due to dispatching error of the context
/stockquote. Any idea to fix the problem ?
