在Ubuntu下进行Fortran网络编程,需借助外部库实现,核心步骤如下:

  1. 安装基础工具与库

    • 安装Fortran编译器(默认gfortran):
      sudo apt update && sudo apt install gfortran
    • 选择网络库(以下为常用方案):
      • libcurl(支持HTTP/FTP等协议):sudo apt install libcurl4-openssl-dev
      • libsocket(轻量级socket接口):需从源码编译安装(参考)。
      • ISO_C_BINDING(Fortran 2003标准,用于调用C网络库):无需额外安装,直接使用。
  2. 编写Fortran代码

    • 示例1:HTTP GET请求(libcurl)
      program http_get
      use iso_c_binding
      implicit none
      interface
          subroutine curl_easy_setopt(curl, option, value) bind(C, name="curl_easy_setopt")
              import c_ptr, c_int
              type(c_ptr), value :: curl
              integer(c_int), value :: option
              type(c_ptr), value :: value
          end subroutine
          function curl_easy_perform(curl) result(res) bind(C, name="curl_easy_perform")
              import c_ptr, c_int
              type(c_ptr), value :: curl
              integer(c_int) :: res
          end function
          subroutine curl_easy_cleanup(curl) bind(C, name="curl_easy_cleanup")
              import c_ptr
              type(c_ptr), value :: curl
          end subroutine
      end interface
      type(c_ptr) :: curl
      integer(c_int) :: res
      curl = curl_easy_init()
      if (curl /= c_null_ptr) then
          call curl_easy_setopt(curl, CURLOPT_URL, "http://example.com")
          res = curl_easy_perform(curl)
          if (res /= 0) print *, "Request failed"
          call curl_easy_cleanup(curl)
      end if
      end program
      
    • 示例2:TCP客户端(libsocket)
      program tcp_client
      use iso_c_binding
      use socket_module  ! 需提前安装libsocket库
      implicit none
      integer(c_int) :: sock
      character(len=100) :: message = "Hello, Server!"
      call socket_create(sock)
      call socket_connect(sock, [127, 0, 0, 1], 12345)  ! 连接本地服务器
      call socket_send(sock, message, len_trim(message))
      call socket_close(sock)
      end program
      
  3. 编译与运行

    • 编译时需链接对应库:
      • libcurl示例:gfortran -o http_get http_get.f90 -lcurl
      • libsocket示例:gfortran -o tcp_client tcp_client.f90 -lsocket
    • 运行程序:./http_get./tcp_client
