[英]Saving Amazon PA API response to JSON file using Python SDK
I am calling the Amazon Product Advertising API in Python to get data for certain products: https://webservices.amazon.com/paapi5/documentation/quick-start/using-sdk.html .我在 Python 中调用亚马逊产品广告 API 以获取某些产品的数据: https : //webservices.amazon.com/paapi5/documentation/quick-start/using-sdk.html 。
I import the API with:我使用以下命令导入 API:
from paapi5_python_sdk.api.default_api import DefaultApi
from paapi5_python_sdk.models.search_items_request import SearchItemsRequest
from paapi5_python_sdk.models.search_items_resource import SearchItemsResource
I call the API using this:我使用这个调用 API:
response = default_api.search_items(search_items_request)
Then I try to write the response object to a file using basic code:然后我尝试使用基本代码将响应对象写入文件:
with open('paapi_response.json', 'w') as outfile:
outfile.write(response)
But I get the following error:但我收到以下错误:
TypeError : write() argument must be str, not SearchItemsResponse
TypeError : write() 参数必须是 str,而不是 SearchItemsResponse
I don't want to convert it to string because I want to keep the exact response of the file.我不想将其转换为字符串,因为我想保留文件的确切响应。 Is there any way to print the response object to a file just as it is?
有没有办法将响应对象按原样打印到文件中?
The SearchItemsResponse
has a to_dict
method which recursively converts it to a nested dictionary/list data structure. SearchItemsResponse
有一个to_dict
方法,它递归地将其转换为嵌套的字典/列表数据结构。 1 1
This you can write to a file as JSON as shown in How do I write JSON data to a file?您可以将其作为 JSON 写入文件,如如何将 JSON 数据写入文件中所示? :
:
import json
# ...
with open('paapi_response.json', 'w') as outfile:
json.dump(response.to_dict(), outfile)
