DynamoDB仅从JSON列表中保存一个记录

Question

我正在尝试循环浏览JSON文件中的URL列表，调用API，然后将结果保存在数据库中。它循环遍历整个列表，但仅保存了第一个URL结果。在每个API调用后，如何将所有URL保存在循环中？

我的代码：

exports.putItemHandler = async (event) => {
const { body, httpMethod, path } = event;
if (httpMethod !== 'POST') {
    throw new Error(`postMethod only accepts POST method, you tried: ${httpMethod} method.`);
}
// All log statements are written to CloudWatch by default. For more information, see
// https://docs.aws.amazon.com/lambda/latest/dg/nodejs-prog-model-logging.html
console.log('received:', JSON.stringify(event));

console.log('----STARTING LOOP----')
console.log(v4())
console.log(urls)

var _id;


try {
    
    for (const url of urls) {

        _id = v4();

        const resp = await axios.get(endpoint, {
            params: {
                key: API_KEY,
                url: url
            }
        });

        console.log(JSON.stringify(resp.data))

        const lighthouseResults = resp.data;        

        const params = {
            TableName: tableName,
            Item: { id: _id,
                    created_at: new Date().toISOString(),
                    URL: url,
                    fullJson: lighthouseResults,
                },
        };
        await docClient.put(params).promise();
    
        const response = {
            statusCode: 200,
            body,
        };
    
        console.log(`response from: ${path} statusCode: ${response.statusCode} body: ${response.body}`);
        return response;

    }
} catch (err) {
   console.error(err)
}
};
