The API did not treat invalid JSON payloads as a 400 error, as a result returning a 500 error; Before this change, an invalid JSON body would return a 500 error; ```bash curl -v \ --unix-socket /var/run/docker.sock \ -X POST \ "http://localhost/v1.30/networks/create" \ -H "Content-Type: application/json" \ -d '{invalid json' ``` ``` > POST /v1.30/networks/create HTTP/1.1 > Host: localhost > User-Agent: curl/7.52.1 > Accept: */* > Content-Type: application/json > Content-Length: 13 > * upload completely sent off: 13 out of 13 bytes < HTTP/1.1 500 Internal Server Error < Api-Version: 1.40 < Content-Type: application/json < Docker-Experimental: false < Ostype: linux < Server: Docker/dev (linux) < Date: Mon, 05 Nov 2018 11:55:20 GMT < Content-Length: 79 < {"message":"invalid character 'i' looking for beginning of object key string"} ``` Empty request: ```bash curl -v \ --unix-socket /var/run/docker.sock \ -X POST \ "http://localhost/v1.30/networks/create" \ -H "Content-Type: application/json" ``` ``` > POST /v1.30/networks/create HTTP/1.1 > Host: localhost > User-Agent: curl/7.54.0 > Accept: */* > Content-Type: application/json > < HTTP/1.1 500 Internal Server Error < Api-Version: 1.38 < Content-Length: 18 < Content-Type: application/json < Date: Mon, 05 Nov 2018 12:00:18 GMT < Docker-Experimental: true < Ostype: linux < Server: Docker/18.06.1-ce (linux) < {"message":"EOF"} ``` After this change, a 400 is returned; ```bash curl -v \ --unix-socket /var/run/docker.sock \ -X POST \ "http://localhost/v1.30/networks/create" \ -H "Content-Type: application/json" \ -d '{invalid json' ``` ``` > POST /v1.30/networks/create HTTP/1.1 > Host: localhost > User-Agent: curl/7.52.1 > Accept: */* > Content-Type: application/json > Content-Length: 13 > * upload completely sent off: 13 out of 13 bytes < HTTP/1.1 400 Bad Request < Api-Version: 1.40 < Content-Type: application/json < Docker-Experimental: false < Ostype: linux < Server: Docker/dev (linux) < Date: Mon, 05 Nov 2018 11:57:15 GMT < Content-Length: 79 < {"message":"invalid character 'i' looking for beginning of object key string"} ``` Empty request: ```bash curl -v \ --unix-socket /var/run/docker.sock \ -X POST \ "http://localhost/v1.30/networks/create" \ -H "Content-Type: application/json" ``` ``` > POST /v1.30/networks/create HTTP/1.1 > Host: localhost > User-Agent: curl/7.52.1 > Accept: */* > Content-Type: application/json > < HTTP/1.1 400 Bad Request < Api-Version: 1.40 < Content-Type: application/json < Docker-Experimental: false < Ostype: linux < Server: Docker/dev (linux) < Date: Mon, 05 Nov 2018 11:59:22 GMT < Content-Length: 49 < {"message":"got EOF while reading request body"} ``` Signed-off-by: Sebastiaan van Stijn <github@gone.nl> (cherry picked from commit c7b488fbc82604ec23b862ec1edc5a0be9c7793d) Signed-off-by: Sebastiaan van Stijn <github@gone.nl> Upstream-commit: 9e06a421234f0bba8392b9a8908a94ff74f0c254 Component: engine
