Question

我正在使用的API：https://pypi.python.org/pypi/python-amazon-simple-product-api

我有我的代码的这部分

from amazon.api import AmazonAPI
products = self.amazon_api.search_n(1, Keywords=item['upc'], SearchIndex='All')

我得到了例外

SearchException: Amazon Search Error: 'AWS.ECommerceService.NoExactMatches', 'We did not find any matches for your request.'

我试着像这样抓住它

try:
    products = self.amazon_api.search_n(1, Keywords=item['upc'], SearchIndex='All')
    found_match = True
except SearchException:
    logging.warning("No search result found on Amazon for UPC: %s"%(item['upc']))
    found_match = False

但我得到了

NameError: global name 'SearchException' is not defined

然后我在脚本开始时这样做了

from AWS.ECommerceService.NoExactMatches import SearchException

但后来我收到了这个错误

ImportError: No module named AWS.ECommerceService.NoExactMatches

我的问题是如何静默捕获这个特定的SearchException例外？

Answer 1

试试这个：

from amazon.api import AmazonAPI, SearchException

之后，

try:
    products = self.amazon_api.search_n(1, Keywords=item['upc'], SearchIndex='All')
    found_match = True
except SearchException:
    logging.warning("No search result found on Amazon for UPC: %s"%(item['upc']))
    found_match = False

应该按预期工作。

可以找到文档here。

Answer 2

尝试NoExactMatches例外：

from AWS.EcommerceServiec import NoExactMatches

try:
    products = self.amazon_api.search_n(1, Keywords=item['upc'], 
SearchIndex='All')
    found_match = True
except NoExactMatches:
    logging.warning("No search result found on Amazon for UPC: %s"%(item['upc']))
    found_match = False

如何在Python中捕获此特定异常 - amazon.api
