Question

我正在运行一个简单的wsgi服务器，

from run import app

if __name__ == "__main__":
    app.run(threaded=True, debug=True)

我正在使用get请求命中服务器，服务器返回200消息，但不返回任何数据。我收到以下错误消息

Error on request:
Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/werkzeug/serving.py", line 209, in run_wsgi
execute(self.server.app)
  File "/Library/Python/2.7/site-packages/werkzeug/serving.py", line 200, in execute
write(data)
  File "/Library/Python/2.7/site-packages/werkzeug/serving.py", line 175, in write
self.send_header('Server', self.version_string())
 File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/BaseHTTPServer.py", line 401, in send_header
self.wfile.write("%s: %s\r\n" % (keyword, value))
IOError: [Errno 32] Broken pipe

我已经在一些地方读过，使用线程选项应该绕过一个破坏的管道错误，但在我的情况下似乎没有帮助。有没有人有任何想法？

Flask版本为0.12.2。

!!! EDIT !!!

因此，我正在开发的页面的目的是从传单地图中获取用户定义的坐标并调用数据库，在本例中为neo4j。查询工作正常，API也是如此，因为它在邮递员中运作良好。所以问题必须在我的网络应用程序的某个地方。这是我的网页服务器应用程序。也许在Ajax电话中？

from flask import Flask, render_template
from flask_cors import CORS

app = Flask(__name__)
CORS(app)
@app.route('/demo')
def webMap():
    return render_template('demo3.html')

if __name__ == '__main__':
    app.config['DEBUG'] = True
    app.run(host='localhost', port=8090)

这是JS：

var map = L.map('map1').setView([51.506725, -0.076486], 12);

    L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token={accessToken}', {
    attribution: 'Map data &copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors, <a href="http://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>, Imagery © <a href="http://mapbox.com">Mapbox</a>',
    maxZoom: 18,
    id: 'mapbox.streets',
    accessToken: '*************************'
}).addTo(map);


//add start marker to map and delete old marker
var startmarker = null;

map.on('click', function (e) {
    if (startmarker !== null) {
        map.removeLayer(startmarker);
    }
     startmarker = L.marker(e.latlng, {
         title: "Start Point",
     }).addTo(map);
    startcoords = e.latlng.lng.toString() + "&" + e.latlng.lat.toString();
    startmarker.bindPopup("Start " + startcoords);
});


//add end marker to map and delete old marker

var endmarker = null;
map.on('contextmenu', function (e) {
    if (endmarker !== null) {
        map.removeLayer(endmarker);
    }
     endmarker = L.marker(e.latlng, {
         title: "End Point",
     }).addTo(map);
    endcoords = e.latlng.lng.toString() + "&" + e.latlng.lat.toString();
    endmarker.bindPopup("End " + endcoords);
    coords = startcoords+"&"+endcoords;
});

// choose query type, click button & Ajax call to API server

$("#button").click(function() {
    var val = $('input[name=query]:checked').val()
    if (val == 'route') {
        stuff = $.ajax({
            url: "http://127.0.0.1:5000/route&"+coords,
            type: "GET",
            dataType: "json" ,      
        })
        .done(function( json ) {
            alert(JSON.stringify(stuff));  // trying to JSON back will work out how to display it after I get some data returned 
        })
        .fail(function( xhr, status, errorThrown ) {
            alert( "Sorry, there was a problem!");
            console.log( "Error: " + errorThrown );
            console.log( "Status: " + status );
            console.dir( xhr );
        })
        .always(function( xhr, status ) {
            alert( "The request is complete!" );
        });
