I want to Add same nuctk in every request in the body.
But request use the formData i can't convert this to object in interceptor.
My client
package com.example.demo.client;
import com.example.demo.config.NhanhPageFeignClientInterceptor;
import com.example.demo.request.CreateNhanhProductRequest;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
#FeignClient(
value = "nhanhPage",
url = "https://nhanh.vn/product",
configuration = NhanhPageFeignClientInterceptor.class
)
public interface NhanhProductV1Client {
#PostMapping(value = "/item/add", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
String createProduct(#RequestBody CreateNhanhProductRequest request);
}
This is my interceptor
package com.example.demo.config;
import com.example.demo.request.CreateNhanhProductRequest;
import com.fasterxml.jackson.databind.ObjectMapper;
import feign.RequestInterceptor;
import feign.form.FormData;
import feign.form.FormEncoder;
import feign.form.spring.SpringFormEncoder;
import org.springframework.context.annotation.Bean;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import java.io.IOException;
public class NhanhPageFeignClientInterceptor {
#Bean
public RequestInterceptor requestInterceptor() {
return requestTemplate -> {
String bodyTemplate = requestTemplate.bodyTemplate();
byte[] body = requestTemplate.body();
FormData formData = new FormData(MediaType.MULTIPART_FORM_DATA_VALUE, "data" , body);
requestTemplate.header(HttpHeaders.COOKIE, "Some cookie");
};
}
}
How to change the body in feign client interceptor.
