這個特定端點實際上返回塊編碼。通過捲曲一個例子:
$ curl -v -X POST http://localhost:4243/images/create?fromImage=base
* About to connect() to localhost port 4243 (#0)
* Trying ::1...
* Connection refused
* Trying 127.0.0.1...

{"status":"Pulling repository base"}{"status":"Pulling image (ubuntu-quantl) from base","progressDetail":{},"id":"b750fe79269d"}{"status":"Pulling image (ubuntu-quantl) from base, endpoint: https://cdn-registry-1.docker.io/v1/","progressDetail":{},"id":"b750fe79269d"}{"status":"Pulling dependent layers","progressDetail":{},"id":"b750fe79269d"}{"status":"Download complete","progressDetail":{},"id":"27cf78414709"}{"status":"Download complete","progressDetail":{},"id":"b750fe79269d"}{"status":"Download complete","progressDetail":{},"id":"b750fe79269d"}* Closing connection #0
現在,我不知道你如何在Python解析這一點,但在Ruby中,我可以使用Yajl像這樣:
parts = []
Yajl::Parser.parse(body) { |o| parts << o }
puts parts
{"status"=>"Pulling repository base"}
{"status"=>"Pulling image (ubuntu-quantl) from base", "progressDetail"=>{}, "id"=>"b750fe79269d"}
{"status"=>"Pulling image (ubuntu-quantl) from base, endpoint: https://cdn-registry-1.docker.io/v1/", "progressDetail"=>{}, "id"=>"b750fe79269d"}
{"status"=>"Pulling dependent layers", "progressDetail"=>{}, "id"=>"b750fe79269d"}
{"status"=>"Download complete", "progressDetail"=>{}, "id"=>"27cf78414709"}
{"status"=>"Download complete", "progressDetail"=>{}, "id"=>"b750fe79269d"}
{"status"=>"Download complete", "progressDetail"=>{}, "id"=>"b750fe79269d"}
那麼,它不僅分塊編碼,它也是JSON的大塊 - 事實上,我端到了Python寫一個解析器爲好。但感謝您的答案。 –
