SpringCloudGateWay⽹关⽆法返回信息数据与Expect： 100-无线发射电路
continue
最近做⽀付项⽬从⼤的项⽬独⽴出来所以专门搭建了⼀个⽹关。上⽹查了些资料都说SpringCloud GateWay性能⽐较好所以就搭建了，其中踩了不了坑，包括JWT权限验证、限流等。但这些搭建都算⽐较容易⽹上已经有了很多教程。踩的最坑花时间最长的就是⽀付交易后，接收交易通知服务处理过后返回响应数据接收不到。下⾯做的仅做简单模拟。 1.搭建⼀个简单⽹关

2.注册中⼼⽐较简单可以⾃⼰⾃⾏搭建
3.搭建⼀个服务提供者
@RestController
@RequestMapping("/producer")
public class TestController {
@RequestMapping("/foo")
public String foo(String foo) {
return "hello "+foo+"!";
}
@PostMapping("/test")
public Object test(@RequestParam Map<String,String> paramsMap){ System.out.println(paramsMap);
return paramsMap;
}
}
下⾯⽤postMan请求⽹关。
服务接收到参数
⽹关接收到信息
好了，下⾯看下怎么让⽹关接收不到响应信息。
