如何捕获Java应用发送的SOAP请求

Question

I have a REST API written in java and spring which makes a backend call to a SOAP service. The SOAP web service code are packaged in a 3rd party jar. So don't have access to change the code. But I can change the SOAP service endpoint by setting a env variable.

How can I capture the raw SOAP request sent by the REST API?

Answer 1

You can intercept the SOAP Request by using number of tools.

I would suggest either use TCPMonitor ( https://ws.apache.org/tcpmon/tcpmontutorial.html ) or wiresharks ( https://www.wireshark.org/ ).

TCPMonitor acts like a proxy (So your endpoint should point to TCPMonitor), and it will relay the message back to your service.

Wireshark is a network protocol analyser. It captures all the TCP/UDP packets (which includes the HTTP as well). You just have to capture the packets. No modifications from server and client ends required. You can then filter the HTTP/HTTPS packets to look for your requests.

Answer 2

You can always use a network packet Analyser such as tcpdump or wireshark to capture packets sent specifically to your 'endpoint'.

ALTERNATIVELY

You can write a tiny proxy to capture requests on a local port and forward them to the actual endpoint and route response after printing it to sys-out. You, in that case, will specify the proxy as the endpoint to your program.

I am not sure of any existing proxy which does that, but I think haproxy will not .

如果您使用的是Windows，则可以使用ProxyTrace ， PocketSoap和其他PocketSoap.com工具。
