파일 업로드가 C++을 통해 HTTP POST를 사용하여 실패 함

Question

HTTP/1.1 500 내부 서버 오류가 발생합니다. http 패킷에 소켓이 있지만 http 패킷에 데이터가 포함되어 있으며 여기에 파일이 포함되어 있습니다.

POST /my/service HTTP/1.0 
Host: myhostname.com 
Accept: */* 
Content-Type: multipart/form-data; boundary=----acbn1234 
Content-Length: 62 

------acbn1234 
Content-Disposition: form-data; name="segment" 

name 
------acbn1234 
Content-Disposition: form-data; name="segid" 

abc123 
------acbn1234 
Content-Disposition: form-data; name="segname" 

segment1 
------acbn1234 
Content-Disposition: form-data; name="txtfile"; filename="textfile.txt" 
Content-Type: text/plain 

segment information this the data in the file 
------acbn1234-- 

서버 측 아파치 톰캣 서버 콘솔에서 예외

난 서버가 난 (404), 즉 잘못된 요청 생각을 보여줍니다하지 않는 내 HTTP 패킷 괜찮 잘못입니다
