multipart/form-data; boundary 예제 - curl. java apache http 라이브러리

curl을 사용할 때 -F를 사용해 boundary를 사용한 예제이다. 

curl -XPOST "http://up.google.com/up/" -F "key1=value1" -F "key2=value2" -v

*   Trying ...

* Connected to up.google.com (1.1.1.1) port 80 (#0)

> POST /up/ HTTP/1.1

> Host: up.google.com

> User-Agent: curl/7.43.0

> Accept: */*

> Content-Length: 465

> Expect: 100-continue

> Content-Type: multipart/form-data; boundary=------------------------fa94669c2a0ffcbe

>

< HTTP/1.1 100 Continue

< HTTP/1.1 200 OK

< Server: openresty

이를 apache http를 사용해서 boundary 를 적용한 예제이다.
