Krakend http：在封闭的身体上阅读无效
我正在使用 Krakend 构建一个 API 网关来连接三个后端服务。网关总是从一个或两个后端服务返回，并且X-Krakend-Completed header总是设置为 false。
http: invalid Read on closed Body日志中错误的原因可能是什么？
预期行为
GET localhost:8000
回复
{
"user-id": 1,
"payments-id": 1,
"loans-id": 1,
}
实际行为
GET localhost:8000
回复
{
"payment-id": 1
}

我在 GET 请求中不知不觉地发送了一个正文，导致了Krakend http: invalid Read on closed Body错误链接到Github 问题
