我想检索机票价格，但谷歌API不断给我HTTP错误403：禁止。谷歌QPX Express API返回HTTP错误403：禁止 - Python

我检查了我的Developers控制台并启用了QPX Express API。另外，我生成了一个没有限制的API_key。

以下是错误：

你确定你使用的是正确的网址是什么？我原本和你有同样的问题，但发现下面的代码有效。我也在使用请求，这使得传递JSON更直接。

import requests 
url='https://www.googleapis.com/qpxExpress/v1/trips/search?key=%s'%google_api_key 

params = {"request": { 
    "slice": [{"kind": "qpxexpress#sliceInput", 
       "origin": "BOS", 
       "destination": "SFO", 
       "date": "2017-06-30"}], 
    "passengers": {"kind": "qpxexpress#passengerCounts", 
       "adultCount": 1,}, 
    "refundable": "false", 
    "solutions": 20,} 
    } 

requests.post(url, json=params, headers = {'content-type': 'application/json'})
