从Eclipse调用AWS lambda：InvalidRequestContentException

Question

我在这里关注教程：https://docs.aws.amazon.com/toolkit-for-eclipse/v1/user-guide/lambda-tutorial.html#lambda-tutorial-invoke-function 我右键单击了我的编辑器，选择了AWS Lambda - ＆gt;在AWS Lambda上运行函数，然后在输入框中，我尝试了以下但没有一个工作。

test
"test"
{"test", "value"}

我得到了这个例外：

==================== INVOCATION ERROR ====================
com.amazonaws.services.lambda.model.InvalidRequestContentException: Could not parse request body into json: Invalid UTF-8 start byte 0x80
 at [Source: [B@7c56c329; line: 1, column: 3] (Service: AWSLambda; Status Code: 400; Error Code: InvalidRequestContentException; Request ID: 9ecedb86-3310-11e8-9f00-4798fcb419ad)

有人可以帮忙吗？我的输入有什么问题？是否有其他错误，但错误消息未指出？

如果我尝试{"key": "value"}，我就会

如果输入类型是字符串，基本上无法使其工作.....谢谢！

Answer 1

它应该是一个json字符串试试：

{"key": "value"}

Answer 2

不知道为什么，但现在开始使用"test" ......
