400 Bad Request while POSTing json to Flask on openshift
400 Bad Request while POSTing json to Flask on openshift
我已经阅读了所有相关的 SO 问题，但在 RedHat 的 openshift 云平台上将 json 发布到我的 Flask 应用程序 运行 时，我仍然遇到此错误（400 - 错误请求）。
这是我的代码：
flaskapp.py
import os
from datetime import datetime
from flask import Flask, request, flash, url_for, redirect, \
render_template, abort, send_from_directory
app = Flask(__name__)
app.config.from_pyfile('flaskapp.cfg')
@app.route('/')
def index():
return render_template('index.html')
@app.route('/<path:resource>')
def serveStaticResource(resource):
return send_from_directory('static/', resource)
@app.route("/test")
def test():
return "<strong>It's Alive!</strong>"
@app.route('/mine', methods=['POST'])
def mine():
content = request.get_json(force=True)
print content
return "Success!\n"
if __name__ == '__main__':
app.run(debug=True)
这就是我的 app.py 的样子

import imp
import os
import sys
try:
virtenv = os.path.join(os.environ.get('OPENSHIFT_PYTHON_DIR','.'), 'virtenv')
python_version = "python"+str(sys.version_info[0])+"."+str(sys.version_info[1])
os.environ['PYTHON_EGG_CACHE'] = os.path.join(virtenv, 'lib', python_version, 'site-packages')
virtualenv = os.path.join(virtenv, 'bin','activate_this.py')
if(sys.version_info[0] < 3):

application = imp.load_source('app', 'flaskapp.py')
port = application.app.config['PORT']
ip = application.app.config['IP']
app_name = application.app.config['APP_NAME']
host_name = application.app.config['HOST_NAME']
fwtype="wsgiref"
for fw in ("gevent", "cherrypy", "flask"):
try:
imp.find_module(fw)
fwtype = fw
except ImportError:
pass
print('Starting WSGIServer type %s on %s:%d ... ' % (fwtype, ip, port))
if fwtype == "gevent":
from gevent.pywsgi import WSGIServer
WSGIServer((ip, port), application.app).serve_forever()
elif fwtype == "cherrypy":
from cherrypy import wsgiserver
server = wsgiserver.CherryPyWSGIServer(
(ip, port), application.app, server_name=host_name)
server.start()
elif fwtype == "flask":
from flask import Flask
server = Flask(__name__)
server.wsgi_app = application.app
server.run(host=ip, port=port)
else:
from wsgiref.simple_server import make_server
make_server(ip, port, application.app).serve_forever()
这是如何发布数据的：
curl -X POST -H "application/json" -d '{"key":"val"}'
https://python-bonga.rhcloud.com/mine
N/B: 这在本地主机上工作正常
我发现 POST 在不指定 Content-Type 的情况下使用 curl 默认发送 Content-Type application/x-www-form-urlencoded
http://curl.haxx.se/docs/httpscripting.html#POST
并且如果 Flask 中存在（不同的）mimetype，则 json 数据将不可用；因此 request.get_json(force=True) 失败。
因此，我更改了我的代码，先查找表单数据，然后再查找其他内容
if request.form:
content = [item for item in request.form]
print "Content:", ''.join(content)
else:
content = request.get_json(force=True)
print "Content:", content
