在 Python 烧瓶中，我使用 flask.views.MethodView 创建了一个视图，如果我不发送表单，该视图就可以工作。但是，如果我使用 xml.send(form) 发送表单，它就会挂起。

JavaScript 调用：

function jackpot() {
            var form = new FormData();
        var fname = "hello there";
        form.append("filename", fname);
        var xml = new XMLHttpRequest();
        xml.open("POST", "/site/myapp/bob", true);

        console.log("sent")
        xml.onreadystatechange = function () {
            console.log(xml.readyState);
            console.log(xml.status);
            if (xml.readyState == "4" && xml.status == "200"){
                console.log("yes");
                console.log(xml.responseText);
            }
        }
        xml.send(form);
    }

Python脚本：

import flask, flask.views
app = flask.Flask(__name__)

class View1(flask.views.MethodView):
    def get(self):
        pass

    def post(self):
        return "hello world"
        #return str(flask.request.form('filename'))

app.add_url_rule('/site/myapp/bob', view_func=View1.as_view('bob'))

更新

我相信问题现在在 nginx 和 uwsgi 之间。

uwsgi 的输出：

*** uWSGI is running in multiple interpreter mode ***
spawned uWSGI master process (pid: 16582)
spawned uWSGI worker 1 (pid: 16587, cores: 2)
spawned uWSGI worker 2 (pid: 16589, cores: 2)
spawned uWSGI worker 3 (pid: 16591, cores: 2)
spawned uWSGI worker 4 (pid: 16593, cores: 2)

nginx配置：

server {
    listen 22.22.22.22;

    access_log /var/log/nginx/localhost.access_log main;
    error_log /var/log/nginx/localhost.error_log info;

location / {
root /var/www/dude;
}

location /site/ {
       try_files $uri @uwsgi;
}

location @uwsgi {
            include uwsgi_params;
            uwsgi_pass 127.0.0.1:3031;
    }

}

uwsgi 配置：

one@chat-dash:~$ cat /etc/uwsgi.d/myapp.ini 
[uwsgi]
socket = 127.0.0.1:3031
uid = web
gid = web
plugins = python
chdir = /site
module = myapp
callable = app
pythonpath = /python
processes = 4
threads = 2
#enable-threads = true
#daemonize = /var/log/uwsgi/myapp.log

one@chat-dash:~$

这里什么都没有。Flash 正确地返回您的响应。但是，您的 JavaScript 没有看到它，因为您send在定义回调之前调用，这是错误的方式。
