帶參數的Python請求

我是Python的新手，我想知道如果你能幫我解決我遇到的這個問題。我使用Python 2.7與請求模塊，一切都很好，除了我收到的數據不正確。我從代碼收到上述帶參數的Python請求

import requests 

URL = 'https://www.cashbackforex.com/DesktopModules/Chart/Candles.ashx' 
params = {'cp': '03/10/2017 7:30', 'int': '1', 'pair': '1', 'candles': '50', 'timezone': '12', 'candlestype': '0', 'prevTzld': '12', 'inst': '10351841'} 

response = requests.get(URL, params=params) 
print response.content

數據樣本是：

{"Data":"03/10/2017 07:06,1.059010000,1.059220000,1.058980000,1.059190000\n03/10/2017 ...

雖然它應該是：

{"Data":"03/10/2017 07:06,1.060450000,1.060540000,1.060410000,1.060430000\n03/10/2017 ...

感謝您對您的幫助提前。

是不是一個服務器端的問題，或者可能與你的要求的問題。我沒有看到您提供的代碼有任何問題。 –

我不知道，我已經修改並找到解決方案多次，但找不到一個。 –

您應該檢查您的請求參數或您使用的url鏈接，因爲所有'requests.get'都會返回所發現的任何內容，而不會更改它檢索的內容。另外，我建議你通過直接從網站或其他方法嘗試其他方法來驗證您獲得的響應，然後比較兩個結果。所以你可以找出問題出在哪裏。 –

而不是使用request我建議urllib2作爲替代。
這裏是一個例子。我試過了，併成功檢索了所需的輸出。

import urllib2 
import urllib 

params = urllib.urlencode({"cp":"03/10/2017 07:30", "int":1, "pair":1, "candles":50,"timezone":12, "candlestype":0, "prevTzId":12, "inst":10351841}) 

target = "https://www.cashbackforex.com/DesktopModules/Chart/Candles.ashx?" 

body = urllib2.urlopen(target + params) 

print body.read()

輸出

這是我最後的解決方案解決方案，因爲它不提供更改參數的靈活性。 EX：如果我想更改日期和蠟燭數量，我必須仔細檢查鏈接，而不是從參數中更改。 –

您可以使用'urllib.urlencode'來添加鏈接中的參數。我已經更新了我的答案，其中的參數是不同的變量'params'。 –

嘿@RemyJ，非常感謝您的解決方案。我終於找到了在python中使用請求模塊的答案。很明顯，我不知道'和'事情在Python中（我認爲它們是相同的）。最後，我只是將URL從'https：// ......'更改爲「https：//」。 ......「，它的工作原理很好 –
