Python API : JSONDecodeError: Expecting value: line 1 column 1

Question

我在使用此代码的标题中遇到了错误（请参阅下面的完整回溯）。我正在使用网站 API 进行身份验证，然后尝试 post a JSON object 来创建活动，但我不知道自己做错了什么.

我是初学者，所以也欢迎您对我的代码提出批评。这是我第一次处理 API

import requests
import json

client_key = r'xxxxxxxxxxxxx'
client_secret = r'yyyyyyyyy'

#Password authentication
authRequest = requests.post("https://backstage.site.com/backstage/oauth/token?client_id="+ client_key +"&client_secret="+ client_secret)

data = {
    "name": "Demo Campaign",
    "branding_text": "Pizza",
    "cpc": 0.25,
    "spending_limit": 1000,
    "spending_limit_model": "MONTHLY"
}

token = 'Bearer ' + authRequest.json()['access_token']
print(token)
url = "https://backstage.site.com/backstage/api/1.0/xxxxx/campaigns/"

headers = {
    'authorization': 'Bearer ' + token,
    }

resp = requests.post(url=url, data=json.dumps(data), headers={'Content-Type': 'application/json;charset=utf-8','Authorization':"'" + token + "'"})

print(resp.json())

服务器似乎没有return有效的JSON。尝试检查响应代码和 .text 以查看您的请求是否成功以及服务器响应的内容。
