从url解析Json数据时出现未知错误

Question

在解析代码时，我将一些未知的BaseException变为'search-results'或'referencedby-count'，这些查询与其他查询完全相似。

提前致谢。

要解析的json数据：

            params = get_connection_parameters(title)
            r=requests.get(params[0],headers=params[1],timeout=60)
            response = r.content
            data = json.loads(response)

            try:
                c_data = data['search-results']['entry'][0]['citedby-count']
                value = row.strip("\n")+','+str(c_data)
                output.write("\n"+value)
            except BaseException as b:
                print(b) 

}
