Libcurl：无法连接到 Django 开发服务器
我的 C 应用程序需要连接到 Http 服务器并获取响应，但在连接到不在端口 80 上运行的服务器时遇到了一些问题。
我在端口 8000 上使用 Django 开发服务器，而不是 Apache我的开发环境。但我刚刚测试连接到 Apache 端口 80 上的 Django 页面，并且 libcurl 能够连接。我可以在浏览器中连接到端口 8000，但 libcurl 不能。
我尝试过这个网址： http://192.168.1.186:8000/mypage/ 和 http://192.168.1.186/mypage/ 然后将 CURLOPT_PORT 设置为 8000但两者都没有奏效。
具体错误是
libcurl error: 7
libcurl error: couldn't connect to server
服务器正在运行CentOS 5.5，并且我确实通过iptables转发了端口8000并且SELinux被禁用。
我将只包含相关代码。
char* url = "http://192.168.1.186:8000/mypage/";
CURL* curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, url);
curl_easy_setopt(curl, CURLOPT_TIMEOUT, 10);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, wait_for_response);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);
curl_easy_perform(curl);
使用命令行curl也不起作用。curl http://192.168.1.186:8000/mypage/
编辑：我发现如果我将 Apache 切换到端口 8000，curl 工作正常，因此 Django 服务器中的某些内容会忽略我的请求。
My C application needs to connect to an Http server and get a response, and I'm having some trouble connecting to a server that isn't running on port 80.
I'm using the Django development server on port 8000 instead of Apache in my development environment. But I did just test connecting to my Django page on Apache on port 80, and libcurl was able to connect. I can connect to port 8000 in my browser, but libcurl cannot.
I've tried this url: http://192.168.1.186:8000/mypage/ and http://192.168.1.186/mypage/ and then setting CURLOPT_PORT to 8000 but neither have worked.
The specific error is
libcurl error: 7
libcurl error: couldn't connect to server
The server is running CentOS 5.5, and I do have port 8000 forwarded through iptables and SELinux is disabled.
I'll just include the relevant code.
char* url = "http://192.168.1.186:8000/mypage/";
CURL* curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, url);
curl_easy_setopt(curl, CURLOPT_TIMEOUT, 10);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, wait_for_response);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);
curl_easy_perform(curl);
Also using command line curl doesn't work either.curl http://192.168.1.186:8000/mypage/
Edit: I've discovered that if I switch Apache to port 8000 curl works fine, so there is something in the Django server that is ignoring my requests.

我明白了。
我正在使用此命令来启动服务器
python manage.py runserver 192.168.1.186:8000但由于某种原因你必须使用 0.0.0.0:8000 来代替。
python manage.py runserver 0.0.0.0:8000我不知道为什么会这样，但确实如此。
I got it figured out.
I was using this command to start the server
python manage.py runserver 192.168.1.186:8000But for some reason you have to use 0.0.0.0:8000 instead.
python manage.py runserver 0.0.0.0:8000I don't know why that works, but it does.
