Inquire about the processing of one post request

[moonhj3117]

Hi During the test, there is a blockage, so leave a question.

After configuring with the following config When I make a POST request, I get a 404 error

[GIN] 2020/04/04 - 16:40:22 | 404 | 22.113µs | ::1 | POST /ldcc/v1/ai-recruiting/abnormal_keyword/LDCC100

If I try after setting with each backend, it works normally. If I make a mistake, please give me some advice.

{ "endpoint": "/ldcc/v1/ai-recruiting/abnormal_keyword/{company}", "method": "POST", "headers_to_pass": [ "*" ], "extra_config": { "github.com/devopsfaith/krakend/proxy": { "sequential": true } }, "backend": [ { "method" : "GET", "url_pattern": "/v1/companies/valid/{company}", "encoding": "json", "host": [ "http://111.111.111.111" ], "extra_config": { "github.com/devopsfaith/krakend/http": { "return_error_details": "result_auth" } } }, { "url_pattern": "/api/", "method" : "POST", "encoding" : "JSON", "host": [ "http://222.222.222.222" ], "extra_config": { "github.com/devopsfaith/krakend/http": { "return_error_details": "result_ai_resume" } } } ] }

I'm not sure about the 404... but you shouldn't use not safe methods in your request sequence (POST is not safe). you could move the validation request to a LUA snippet (like the one used on this test: https://github.com/devopsfaith/krakend-lua/blob/master/proxy/http_test.go) and reject the request is the response isn't valid

Thank you for your answer Due to Krakend functionality, two backends (POST, POST) on one endpoint or Are two backends (GET, POST) originally provided for one endpoint?

[kpacha]

sending more than one requests when using "unsafe" (not safe by the RFC definition) methods is not supported out of the box. the main reasons are:

• how to deal with the distributed transactions without coordination
• how to deal with several request body reads
• enforcing graceful degradation of the services

Nevertheless, the KrakenD platform offers you several ways to fulfill your requirements by extending and/or customizing the pipe with LUA snippets and go plugins. Take a look at the https://www.krakend.io/docs/extending/writing-plugins/ and https://www.krakend.io/docs/endpoints/lua/
