Web services Jython CGIHTTPServer错误“套接字必须处于非阻塞模式”
通过“jython-m CGIHTTPServer”将jython用作CGI服务器会导致C-Python中不存在的错误:错误:20000,“套接字必须处于非阻塞模式” 如果像我这样的人想使用jython作为jython模型、脚本等的简单CGI服务器,这是不可接受的。我找到了解决办法,希望这也能帮助其他人: 编辑文件jython/Lib/select.py并转到标记行,添加两行箭头,如下所示。然后,所有这些都可以正常工作,正如C-Python所知 jython/Lib/select.py:Web services Jython CGIHTTPServer错误“套接字必须处于非阻塞模式”,web-services,sockets,jython,blocking,Web Services,Sockets,Jython,Blocking,通过“jython-m CGIHTTPServer”将jython用作CGI服务器会导致C-Python中不存在的错误:错误:20000,“套接字必须处于非阻塞模式” 如果像我这样的人想使用jython作为jython模型、脚本等的简单CGI服务器,这是不可接受的。我找到了解决办法,希望这也能帮助其他人: 编辑文件jython/Lib/select.py并转到标记行,添加两行箭头,如下所示。然后,所有这些都可以正常工作,正如C-Python所知 jython/Lib/select.py: ...

在一些应用程序中,我在响应过程中遇到了setblocking0问题。因此,我还修改了jython/Lib/socket.py,如下所示: jython/Lib/socket.py:
class _tcpsocket(_nonblocking_api_mixin):
...
def send(self, s):
try:
if not self.sock_impl: raise error(errno.ENOTCONN, 'Socket is not connected')
if self.sock_impl.jchannel.isConnectionPending():
self.sock_impl.jchannel.finishConnect()
numwritten = self.sock_impl.write(s)
# try again in blocking mode
if numwritten == 0 and self.mode == MODE_NONBLOCKING: # <-- line to add
try: self.setblocking(1) # <-- line to add
except: pass # <-- line to add
numwritten = self.sock_impl.write(s) # <-- line to add
if numwritten == 0 and self.mode == MODE_NONBLOCKING:
raise would_block_error()
return numwritten
except java.lang.Exception, jlx:
raise _map_exception(jlx)

我知道这两个更改都不是很“干净”,但这是让Jython作为CGIHTTPServer像Python一样工作的唯一方法
