用於POST請求的燒瓶404

-2

我對燒瓶很新。試圖構建一個燒錄應用程序，從後端neo4j獲取數據並將其以JSON格式發佈。最終的目標是使用d3.js進行可視化。但對於初學者，我想把它發佈爲JSON。用於POST請求的燒瓶404

下面是我的views.py：

import models 
from models import Customer 
from flask import Flask, request, session, redirect, url_for, render_template, flash,json,jsonify 
import os 
app = Flask(__name__) 
@app.route('/',methods = ['GET','POST']) 
def enter_ID(): 
    if request.method == 'POST': 
     Galactic_ID = request.form['Galactic_ID'] 
     if Customer(Galactic_ID).find(): 
      return redirect(url_for('Customer_relationships',Galactic_ID=request.form.get('Galactic_ID'))) 
     else: 
      return "Wrong Galactic_ID" 

    else: 
     return render_template('Gal.html') 

@app.route('/Customer_relationships/<Galactic_ID>') 
def Customer_relationships(Galactic_ID): 
    data = Customer(Galactic_ID).get_relationships(): 
    return render_template('rel.html',Galactic_ID=Galactic_ID,data =json.dumps(data)) 



if __name__ == '__main__': 
    host = os.getenv('IP','0.0.0.0') 
    port = int(os.getenv('PORT',5000)) 
    app.secret_key = os.urandom(24) 
    app.run(host=host,port=port)

在views.py，客戶（Galactic_ID）.find（）和客戶（Galactic_ID）.get_relationships（）調用的函數找到（個體經營）和get_relationships（個體經營）下Customer類在models.py：下面

當我嘗試和運行這個是HTTP調用：

127.0.0.1 - - [29/Jul/2016 17:54:53] "GET/HTTP/1.1" 200 - 
127.0.0.1 - - [29/Jul/2016 17:54:56] "POST/HTTP/1.1" 302 - 
127.0.0.1 - - [29/Jul/2016 17:54:56] "GET /Customer_relationships/2000000000084001287 HTTP/1.1" 200 - 
127.0.0.1 - - [29/Jul/2016 17:54:56] "POST /Customer_relationships HTTP/1.1" 404 -

爲什麼要將'returnObject'轉換成JSON字符串而不是僅僅返回它的目錄？ – dirn

@davidism現在已修復。 –

@davidism關於如何將returnsObject從models.py傳遞給views.py？ –

下面是工作的解決方案：

import models 
from models import Customer 
from flask import Flask, request, session, redirect, url_for, render_template, flash,json,jsonify 
import os 
app = Flask(__name__) 
@app.route('/',methods = ['GET','POST']) 
def enter_ID(): 
    if request.method == 'POST': 
     Galactic_ID = request.form['Galactic_ID'] 
     if Customer(Galactic_ID).find(): 
      return redirect(url_for('relationships',ID=request.form.get('Galactic_ID'))) 
     else: 
      return "Wrong Galactic_ID" 

    else: 
     return render_template('Gal.html') 
@app.route('/Customer_relationships',defaults={'ID':'Galactic_ID'},methods=['GET','POST']) 
@app.route('/Customer_relationships/<ID>',methods=['GET','POST']) 
def relationships(ID): 
    data = Customer(ID).get_relationships() 
    return render_template('rel.html',data= json.dumps(data)) 





if __name__ == '__main__': 
    host = os.getenv('IP','0.0.0.0') 
    port = int(os.getenv('PORT',5000)) 
    app.secret_key = os.urandom(24) 
    app.run(host=host,port=port)
