Question

所有

我有一个使用Flask构建两个端点的API。我正在使用nginx / uwsgi组合进行服务，每当我向其中一个端点发送GET请求时，我都会收到一个奇怪的错误。另一个端点工作正常。

以下是来自get请求的uwsgi日志的输出

File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1646, in request_context
    return RequestContext(self, environ)
File "/usr/local/lib/python2.7/dist-packages/flask/ctx.py", line 166, in __init__
    self.url_adapter = app.create_url_adapter(self.request)
File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1475, in create_url_adapter
    server_name=self.config['SERVER_NAME'])
File "/usr/local/lib/python2.7/dist-packages/werkzeug/routing.py", line 1196, in bind_to_environ
    environ['REQUEST_METHOD'], environ.get('PATH_INFO'),
KeyError: 'REQUEST_METHOD'

并且，这是来自get请求的nginx错误日志的输出

2013/12/26 15:22:16 [error] 833#0: *9 upstream prematurely closed connection while reading response header from upstream, 
client: 71.71.53.31, server: scholarly, 
request: "GET /citelet/ HTTP/1.1", 
upstream: "uwsgi://unix:///tmp/citelet.sock:", 
host: "162.243.219.38"

我为这个问题的模糊性道歉。我已经在相同的硬件上使用相同的库多次设置此服务器，之前没有任何问题。错误令人困惑，我不确定从哪里开始寻找。

提前致谢！

Answer 1

愚蠢的错误。我的nginx配置出错了。它指向一个不存在的套接字。

server {
    listen   80;
          server_name scholarly;
      # crowdscholar endpoint
        location /crowdscholar {
            uwsgi_pass unix:///tmp/crowdscholar.sock;
        include uwsgi_params;
        # strip path before handing it to app
        uwsgi_param SCRIPT_NAME /crowdscholar;
        uwsgi_modifier1 30;
    }
    # citelet endpoint
        location /citelet {
            uwsgi_pass unix:///tmp/citelet.sock;
        include uwsgi_params;
        # strip path before handing it to app
        uwsgi_param SCRIPT_NAME /citelet;
        uwsgi_modifier1 30;
    }
}

Answer 2

仅供参考：我收到同样的错误，并意识到我忘记在user1558914的答案中添加include uwsgi_params;。

然后它仍然没有在make restart之后工作，因为我在nginx重启之前有我的uwsgi重启规则，它失败了。一旦我用/etc/init.d/nginx restart手动重启nginx，KeyError就停止了。
