GetLowestPricedOffersForSKU处理参数失败

Question

我在尝试调用GetLowestPricedOffersForSKU时遇到了一个小问题,我收到了响应:

处理org.jboss.resteasy.spi.metadata的参数失败

我可以调用Product Api中的其他函数,它们工作正常,只是在这个函数上得到上述错误.

我已经在网上寻找答案,但找不到任何与此相关的内容,是否有人知道我为什么会这样做？

顺便说一句,它在MWS Scratchpad中运行良好!

Answer 1

发帖以防其他人遇到这个问题并且像我一样困惑。除了这一特定请求之外，几乎所有 Amazon MWS 请求的工作方式都存在根本性差异。从技术上讲，所有其他请求都接受参数作为查询参数而不是 POST 数据。暂存器甚至表明这就是它实际工作的方式（尽管 MWS 暂存器实际上也将数据作为发布数据字段发送）。

这段代码对我有用。希望它能帮助某人。
