如何使用Spring Cloud Feign发布表单URL编码的数据 [英] How to POST form-url-encoded data with Spring Cloud Feign

问题描述

使用spring-mvc批注，如何定义可以通过表单URL编码的@FeignClient?

Using spring-mvc annotations, how can I define an @FeignClient that can POST form-url-encoded?

推荐答案

使用表单编码器进行假冒: https ://github.com/OpenFeign/feign-form ，您的伪装配置如下所示:

Use form encoder for feign: https://github.com/OpenFeign/feign-form and your feign configuration can look like this:

class CoreFeignConfiguration {

  @Autowired
  private ObjectFactory<HttpMessageConverters> messageConverters

  @Bean
  @Primary
  @Scope(SCOPE_PROTOTYPE)
  Encoder feignFormEncoder() {
      new FormEncoder(new SpringEncoder(this.messageConverters))
  }
}

然后，可以这样映射客户端:

Then, the client can be mapped like this:

@FeignClient(name = 'client', url = 'localhost:9080', path ='/rest', configuration = CoreFeignConfiguration)
interface CoreClient {

    @RequestMapping(value = '/business', method = POST, consumes = MediaType.APPLICATION_FORM_URLENCODED)
    @Headers('Content-Type: application/x-www-form-urlencoded')
    void activate(Map<String, ?> formParams)
}
