当使用django crontab将python函数添加到cron时，会出现“无法解码任何JSON对象”错误

当我在django shell上执行python函数时，它执行得很好。 但是当函数通过crontab执行时，它不会给出任何JSON对象可能被解码的错误

successfully made the api call. response status is  200
Exception occured : No JSON object could be decoded

我正在我的代码中做一个POST调用来splunk rest api

payload = {'search' : 'search index="xyz" | table a , b , c' , 'earliest_time' : '-60m' , 'output_mode' : 'json_rows' }
url = "https://localhost:8089/services/search/jobs/export"
headers = {'content-type': "application/x-www-form-urlencoded",'authorization': "xyz",'cache-control': "no-cache"}
response = requests.adapters.HTTPAdapter(pool_connections=10, pool_maxsize=10, max_retries=5, pool_block=False)
response = requests.request("POST", url, data=payload, headers=headers, verify=False)            
response = response.json()

只有在cron中运行python函数时，才会出现错误

我使用的是python版本：2.7.10

django:1.8

当您没有来自api的响应时，您没有得到任何JSON对象可能被解码的错误

就连我也有同样的问题。我正在对splunk进行REST api调用，我想收集每30分钟生成的摘要索引数据。所以我的cron每30分钟运行一次。但每30分钟api仍在聚合数据，因此每30分钟失败一次。 当我以一个时间延迟点击api时，也就是数据正确聚合的时间，我得到了响应

现在我的cron是这样的：

 5-59/30 * * * *

此cron将在5分钟后运行，35分钟后运行

检查print response.text before response.json response.text在django shell上运行时打印。但是response.text作为cron运行时不会打印任何内容。发布您的response.text谢谢。它在为我的cron设置提供了时间延迟后工作。
