我正在编写一个简单的flask应用程序,根据我的查询,我应该以所需的格式获得所需的答案。 代码如下;
#-*- coding: utf-8 -*-
import StringIO
import os
import pandas as pd
import numpy as np
from flask import Flask, request, Response, abort, jsonify, send_from_directory,make_response
import io
from pandas import DataFrame
import urllib2, json
import requests
from flask import session
import sys
reload(sys)
sys.setdefaultencoding("ISO-8859-1")
app = Flask(__name__)
@app.route("/api/conversation/", methods=['POST'])
def chatbot():
df = pd.DataFrame(json.load(urllib2.urlopen('http://192.168.21.245/sixthsensedata/server/Test_new.json')))
question = request.form.get('question')
store = []
if question == 'What is the number of total observation of the dataset':
store.append(df.shape)
if question == 'What are the column names of the dataset':
store.append(df.columns)
return jsonify(store)
if __name__ == '__main__':
app.debug = True
app.run(host = '192.168.21.11',port=5000)
它运行正常,但响应为空。我想再创建约30个这样的问题,并将值存储在store
数组中。但是,我认为值没有被附加到store
内。
不过,在jupyter笔记本中,我得到了适当的答复;
df = pd.DataFrame(json.load(urllib2.urlopen('http://192.168.21.245/sixthsensedata/server/Test_new.json')))
store = []
store.append(df.shape)
print store
[(521, 24)]
为什么在烧瓶中没有附加值?我正在邮递员中测试我的应用程序。请指导我缺少的地方。
答案 0 :(得分:1)
不提供Post方法的数据类型时,request.form的计算结果为
ImmutableMultiDict([('{"question": "What is the number of total observation of the dataset"}', u'')])
和question = request.form.get('question')
最终都不是
您可以显式使用内容类型作为json,或强制加载它。
@app.route('/api/conversation/', methods=['POST'])
def chatbot():
question = request.get_json(force=True).get('question')
store = []
if question == 'What is the number of total observation of the dataset':
store.append("shape")
elif question == 'What are the column names of the dataset':
store.append("columns")
return jsonify(store)
