如何在瓶子後期方法中提出請求？

我想寫一些代碼使用瓶讓其他服務器可以發佈一些數據，然後在燒瓶內，當我收到來自外部的電話，我想做另一個帖子到另一臺服務器。如何在瓶子後期方法中提出請求？

下面是我的代碼

from flask import Flask, jsonify, request 
import json 
import requests 

app = Flask(__name__) 


@app.route("/sendData.json", methods=['POST']) 
def receiveImageData(): 
    imageData = request.json 

    # save data to son file 
    with open(request.json['image_filename'].split('.')[0] + '.json', 'w+') as f: 
     json.dump(imageData, f, indent=4) 

    # post some data to this url 
    r = requests.post('http://example.com/example.json', son = {'image_filename':'test.jpg', 'image_url': "http://images.come"}) 

    # return json data back for /sendData.json 
    return jsonify({"status": "success"})

的問題是最後一行{「狀態」：「成功」}不會爲sendData.json返回。

我該如何解決這個問題，或者應該有另一種方法來實現這一點？

下面是從燒瓶錯誤日誌

請檢查您的Json.dumps功能。另外我需要問你做什麼來獲取Json數據，因爲你的方法只允許POST請求。 –

Json.dump函數沒問題，我只想將sendData.json文章中的數據保存到.json文件中，之後我想調用一個後期api。 – Dreams

requests.post在做什麼？ –

在receiveImageData()年底與return Response(), 200試試吧。

編輯：

我研究了一下。其實它應該工作。試試這樣的：

return jsonify({"success": True}), 202

你得到什麼錯誤消息？它是相同的服務器/ API，你發佈你的數據和狀態：成功？

無法正常工作。另外，我想返回一些json數據。 – Dreams

你可以給你添加一些評論片段嗎？ –

只需添加它，謝謝。 – Dreams

，而不是使用jsonify({"status": "success"})：

return (Response(),200)

不能正常工作，而且我想返回一些json數據。 – Dreams
