[英]Python wrapper for UDT C++ library
I want to use the UDT library in Python, so I need a wrapper. 我想在Python中使用UDT库 ,所以我需要一个包装器。 I found this one: pyudt , but I dont know exactly how to use this to send files from a peer to peer.
我找到了这个: pyudt ,但我不确切知道如何使用它来发送来自对等的文件。 Can anybody point me in the right direction?
任何人都能指出我正确的方向吗?
after so many time I've found this question and its solution: 经过这么多次,我发现了这个问题及其解决方案:
The steps to install pyudt-0.1a are: 安装pyudt-0.1a的步骤如下:
install: libboost-python1.46-dev or equivalent (for instance, in linux-ubuntu12.04 it's in the reps.) 安装:libboost-python1.46-dev或等效的(例如,在linux-ubuntu12.04中,它位于代表中。)
install udt.h (from: http://sourceforge.net/projects/udt/ ) into a system directory, 将udt.h(来自: http : //sourceforge.net/projects/udt/ )安装到系统目录中,
OR 要么
(put the udt.h file in the same path as the pyudt-0.1a files, and then change a line of the "pyudt.cpp", from: (将udt.h文件放在与pyudt-0.1a文件相同的路径中,然后从以下位置更改“pyudt.cpp”的一行:
#include <udt.h>
to: 至:
#include "udt.h"
). )。
eg.: 例如。:
... libraries=['udt', 'boost_python-py27'])
you must correct a bug, changing from: 你必须纠正一个错误,改变:
int r = UDT::send(_sock, data.c_str(), data.length(), 0);
to: 至:
int r = UDT::send(_sock, data.c_str(), data.length()+1, 0);
because the character "\\0" meaning the end of string must also be sent, otherwise junk would be appended to your string. 因为字符“\\ 0”表示字符串的结尾也必须发送,否则垃圾将附加到您的字符串。
optionally, you may choose between: 您可以选择:
_sock = UDT::socket(AF_INET, SOCK_DGRAM, 0); --» default
or: 要么:
_sock = UDT::socket(AF_INET, SOCK_STREAM, 0); --» optional
in the corresponding folder: 在相应的文件夹中:
python2.7 ./setup.py build
sudo python2.7 ./setup.py install
OR, (if you don't have admin permissions to install it for all the users, and just wanna try it for you: 或者,(如果您没有管理员权限为所有用户安装它,并且只是想为您尝试:
python2.7 ./setup.py build
python2.7 ./setup.py install --prefix=~/pyudt-0.1a/installation_dir/ #in this case, pyudt would only work if called from that directory
) )
Then, the code for a simple client can be: 然后,简单客户端的代码可以是:
import pyudt
socket = pyudt.pyudt_socket()
socket.connect(("127.0.0.1", 7000))
socket.send("hello_world!")
and it works, it talks with my cpp server! 它工作,它与我的cpp服务器谈话!
notice: if you need more help you can write in the python's console: 注意:如果您需要更多帮助,可以在python的控制台中编写:
import pyudt
dir(pyudt.pyudt_socket) # to list the available functions
help(pyudt) # to get more help
PS. PS。 the files created with this installation tutorial are: /usr/local/lib/python2.7/dist-packages/pyudt.so, and /usr/local/lib/python2.7/dist-packages/pyudt-0.1a.egg-info
使用此安装教程创建的文件是:/usr/local/lib/python2.7/dist-packages/pyudt.so,/usr/local/lib/python2.7/dist-packages/pyudt-0.1a.egg -信息
You can give my udt_py fork a try. 你可以尝试一下我的udt_py fork 。 It includes a sample
recvfile.py
now and can retrieve files from the sendfile
daemon in udt's app
directory. 它现在包含一个示例
recvfile.py
,可以从udt的app
目录中的sendfile
守护进程中检索文件。
