英文:
Send multiple key in Feign Client
问题
我有一个使用Feign Client进行表单URL编码的nxt请求POST
@FeignClient(
url = "${url}", configuration = NxtApi.Configuration.class)
public interface NxtApi {
@PostMapping(value = "nxt", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String new(
@RequestParam String requestType, @RequestBody Map<String, ?> payload);
class Configuration {
@Bean
Encoder feignFormEncoder(ObjectFactory<HttpMessageConverters> converters) {
return new SpringFormEncoder(new SpringEncoder(converters));
}
@Bean
Logger.Level feignLoggerLevel() {
return Logger.Level.FULL;
}
}
}
我想要发送相同的键和两个值
Map<String, Object> param = new HashMap<>();
param.put("filter", valueOne);
param.put("filter", valueTwo);
api.new("asset", param);
**我需要像这样的内容**
filter=valueOne&filter=valueTwo
但它被发送成这样（日志中的请求响应）
filter=[valueOne, valueTwo]
感谢任何帮助。

Thanks for any help.

你需要使用一个字符串值的列表（List of String values）来代替一个映射（Map）。
@PostMapping(value = "nxt", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String new(@RequestParam String requestType, @RequestParam("filter") List<String> filter, @RequestBody Map<String, ?> payload);

英文:
You will have to use a List of String values instead of a Map.
@PostMapping(value = "nxt", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String new(@RequestParam String requestType, @RequestParam("filter") List<String> filter, @RequestBody Map<String, ?> payload);
as I found it here: https://stackoverflow.com/questions/41744542/spring-cloud-feign-client-requestparam-with-list-parameter-creates-a-wrong-requ
