一旦我在终端中输入curl代码，我就可以得到200，所以我假设我编写teststytch的方式到目前为止还可以。但是，一旦我试图集成到一个java文件中，就会得到一个错误的请求响应。我现在有点不知所措。https://github.com/libetl/curl 这就是我所说的转换我的curl代码。
这就是我犯的错误。httpresponseproxy{http/1.1 400坏请求[date:thu，22 apr 2021 23:21:42 gmt，content type:application/json，content length:189，connection:keep alive，traceparent:00-d3a39218eb8d091ffe3bf5cb4746922ce-353a1a23da4e5dc4-01]响应代理{[content type:application/json，content length:189，chunked:false]}
