Handling of StreamingBody Response from Invoking a Lambda Function

When calling a Lambda Function via Boto3, the returned object is something like:

{u'Payload': <botocore.response.StreamingBody object at 0x7f8d5b62ac50>, 
'ResponseMetadata': {'RetryAttempts': 0, 'HTTPStatusCode': 200, 'RequestId': '5bdbb3ca-3b35-11e7-9816-397b140c3bac', 'HTTPHeaders': {'x-amzn-requestid': '5bdbb3ca-3b35-11e7-9816-397b140c3bac', 'content-length': '1636', 'x-amzn-trace-id': 'root=1-591ca199-00d34d5474d16275ec2c8d10;sampled=0', 'x-amzn-remapped-content-length': '0', 'connection': 'keep-alive', 'date': 'Wed, 17 May 2017 19:16:41 GMT', 'content-type': 'application/json'}}, u'StatusCode': 200}

The Payload parameter is <botocore.response.StreamingBody> which is a data streaming object.

捕捉浏览器中的JS运行时错误，主要通过监听window.onerror来实现。但是对于不同的脚本执行方式以及不同的浏览器，能捕获到的信息会有区别。

window.onerror 讲接收3个参数：

• msg：错误描述，比如：a is not defined
• url：出错脚本所在的url
• lineNumber：出错脚本的行数

本文将对不同浏览器和不同的脚本执行方式进行测试，并总结这些区别。
