@heyuanchao 你好，使用gomod，不要用gopath

运行 https://github.com/micro-in-cn/tutorials/tree/master/examples/basic-practices/micro-api/rpc 中的例子报错

# curl -H 'Content-Type: application/json' -d '{"name": "小小先"}' "http://localhost:8080/example/call"
POST http://localhost:8080/example/call
Content-Type: application/json

{"name": "小小先"}

{"id":"go.micro.api","code":500,"detail":"error during request: unknown field \"name\" in go_api.Request","status":"Internal Server Error"}

我改了下代码：

if req.Method != "POST" {
		return errors.BadRequest("go.micro.api.example", "method: [%v], require post", req.Method)
	}

# curl -H 'Content-Type: application/json' -d '{}' http://localhost:8080/example/foo/bar
POST http://localhost:8080/example/foo/bar
Content-Type: application/json

{"id":"go.micro.api.example","code":400,"detail":"method: [], require post","status":"Bad Request"}

@heyuanchao 请不要在无关issue下问无关的问题，需要新建issue
