Hello, I found when using your npm package that when the request header is 'x-www-form-urlencoded', req.body cannot be obtained in the function corresponding to response; and the request header is 'application/json' can be used normally. So I checked the part of your code about getting the body (i.e. parseJson), and made some changes to be compatible with both form and json formats. I packaged it and tested it myself, I hope it can be adopted.
您好，我在使用您的npm包时发现，当请求头为‘x-www-form-urlencoded’时，无法在response对应的函数中，获取req.body；而请求头为‘application/json’时可以正常使用。于是我查看了您代码中关于获取body的部分（即parseJson），并且做了一些改动以此来兼容表单和json两种格式的情况。我打包自测过了，希望可以采纳。
