類型錯誤：字符串索引必須是整數 - check_dell_warrant.py

Question

我使用Nagios的開發的插件，但在特定的主機上運行時，我得到一個錯誤。我通常會進行調試，但是對於python編程來說是非常新的。我得到的錯誤是：

Traceback (most recent call last): 
    File "/usr/lib64/nagios/plugins/check_dell_warranty.py", line 755, in <module> 
    parse_exit(RESULT, options.short_output) 
File "/usr/lib64/nagios/plugins/check_dell_warranty.py", line 589, in parse_exit 
    days, short_output) 
File "/usr/lib64/nagios/plugins/check_dell_warranty.py", line 557, in process_asset 
days, short_output) 
File "/usr/lib64/nagios/plugins/check_dell_warranty.py", line 497, in build_warranty_line 
description = warranty['ServiceLevelDescription'] 
TypeError: string indices must be integers 

該腳本的代碼所示：

def build_warranty_line(warranty, full_line, days, short_output): 
''' 
This function takes a warranty object and parses the salient information 
out. It then calculates the number of days remaining in the warranty 
period, and builds a line for Nagios outputting. 
''' 

description = warranty['ServiceLevelDescription'] 
end_date = warranty['EndDate'] 
start_date = warranty['StartDate'] 
provider = warranty['ServiceProvider'] 

logger.debug('Found: Start date: {0}, End Date: {1},Description: {2}, ' 
      'Provider: {3}'.format(start_date, end_date, description, 
            provider)) 

如果我在調試模式下運行腳本它表明這是傳遞給這個函數的原始數據是：

有人可以幫我解決這個問題嗎？

您必須向我們顯示實際致電build_warranty_line，但您的錯誤意味着warranty是一個字符串，而不是字典。 JSON響應是否json.loads？
