Feign microservice call, how to put parameters after the URL in post request

 In the Feign microservice call, you can make a POST request by adding parameters after the URL. Parameters can be passed in two ways: as path parameters or query parameters.

Path parameter: You can add parameters to the path of the URL and use the @PathVariable annotation to get the value of the parameter. For example:

@FeignClient(name = "example-service")
public interface ExampleFeignClient {
    @PostMapping("/example/{param}")
    void postWithPathVariable(@PathVariable("param") String param, @RequestBody Object body);
}

1. In the above example, param is the path parameter, which can be obtained through the @PathVariable annotation. The @RequestBody annotation is used to pass the request body as a parameter to the POST request.

2. Query parameters: You can add parameters to the query string of the URL and use the @RequestParam annotation to get the value of the parameter. For example:

@FeignClient(name = "example-service")
public interface ExampleFeignClient {
    @PostMapping("/example")
    void postWithQueryParameter(@RequestParam("param") String param, @RequestBody Object body);
}

1. In the above example, param is the query parameter, which can be obtained through the @RequestParam annotation. The @RequestBody annotation is used to pass the request body as a parameter to the POST request.

When using Feign to call microservices, you can choose a suitable method to pass parameters according to actual needs. Whether it is a path parameter or a query parameter, you can add parameters after the URL to make a POST request.
