go web 参数获取错误

Question

go iris web 框架，同时有两个请求到达go的时候，参数会有上次请求的部分参数。最后导致json序列化时失败

readObjectStart: expect { or n, but found  , error found in #0 byte of ...||..., bigger context ...||...

场景重现：

1、登录

在go语言的net/http/server.go源码 1822行func (c *conn) serve(ctx context.Context) {}函数debug，

c.bufr.buf的值是：

POST /auth/login HTTP/1.1
Host: localhost:9000
Connection: keep-alive
Content-Length: 405

这里的参数获取是OK的，登录也是成功的。

2，登录后同时发起了2个请求reload和page,其中reload请求不带参数，page携带参数:

但是在net/http/server.go源码 1822行func (c *conn) serve(ctx context.Context) {}函数断点是发现参数异常：

POST /subject/page HTTP/1.1

其中的参数竟然有部分以前的请求参数混入其中。导致json序列化失败，请问下这个问题怎么解决，原因是什么？

Answer 1

每次请求参数前，请进行初始化操作
