curl , wget 說明

  • wget

    • GNU Wget is a free software package for retrieving files using HTTP, HTTPS and FTP, the most widely-used Internet protocols
    • wget 只支援下載(using HTTP, HTTPS and FTP)且無法上傳資料

  • curl

    • curl is a tool to transfer data from or to a server, using one of the supported protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP)
    • curl is used in command lines or scripts to transfer dat
    • curl支援上傳及下載

  • 兩者差異

    • library. curl is powered by libcurl - a cross-platform library with a stable API that can be used by each and everyone.
    • Wget is command line only. There’s no library.
    • HTTP auth. curl supports more HTTP authentication methods, especially over HTTP proxies: Basic, Digest, NTLM and Negotiate
    • Wget supports only Basic auth as the only auth type over HTTP proxy

使用範例

1
-T, --upload-file <file>
1
curl -T "img[1-1000].png" ftp://ftp.picturemania.com/upload/

curl cross compile 不包含ssl及zlib

1
wget http://curl.haxx.se/download/curl-7.37.1.tar.gz

  • 設定環境

    make

    make install

./configure --prefix=/opt/DOCKER-erwin-build-hiv200/work/cross-compile/curl/build --target=${CROSS_COMPILE} --host=${CROSS_COMPILE} --build=i586-pc-linux-gnu
  • 產生bin及so如下

curl 為119Kbyte

libcurl.so.4.3.0 為354Kbyte

curl compile openssl 開啟ssl及zlib

  • 先設定prebuild final目錄如下(將剛剛產生的.so及.h)整理如下

curl 為 119K

libcurl.so.4.3.0為 413K

與原本的大小差不多，但需要ssl、cypto及zlib的lib (至少要3Mbyte)
