[Java] feignclient如何支持第三方application/x-www-form-urlencoded的接口
第三方接口,只支持application/x-www-form-urlencoded的数据提交方式,解决过程比较曲折,记录一下
解决方案一(后面证实是失败的,仅供参考)
通过自定义FeignClient的配置类来解决
proxy代码参考
@ConditionalOnProperty("flan.api.url") @FeignClient(name = "${flan.api.url:}", url = "${flan.api.url:}", path = "/OpenPlatform", configuration = {FeignClientConfig.class, FlanOrderProxy.Configuration.class} ) public interface FlanOrderProxy { @PostMapping(value = "/pushOrderDetail", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE) DataResult<Object> push( @RequestHeader Map<String, String> headerMap, @RequestBody Map<String, ?> postData ); @GetMapping("/cancelOrder?order_no={orderNo}") DataResult<Object> cancel( @RequestHeader Map<String, String> headerMap, @PathVariable(value = "orderNo") String orderNo ); class Configuration { @Bean @Primary Encoder feignFormEncoder(ObjectFactory<HttpMessageConverters> converters) { return new SpringFormEncoder(new SpringEncoder(converters)); } } }
解说
client代码参考
public DataResult<Object> push(StoreSaasFlanOrderPushRequest request) { Map<String, String> postData = new HashMap<>(); postData.put("detail", JSON.toJSONString(request)); return flanOrderProxy.push( FlanApiUtils.assembleHeaders(request.getAuthorization()), postData ); }
解说
代码就差不多这样了,本地运行,正常!然后打包上测试环境,死了,老是报这个错!
Could not write request: no suitable HttpMessageConverter found for request type [java.util.HashMap] and content type [application/x-www-form-urlencoded]
这个错误的意思是,proxy类根本就没有使用到 Configuration这个类去encode数据!也就是说
调试了好久,一开始以为是test的代码分支有问题,把test分支checkout到本地,也是能正常运行的!没办法,只能又google了!
解决方案二
在不断搜索和尝试方案之后,终于找到了能解决的方式了!

解说
client代码参考
public DataResult<Object> push(StoreSaasFlanOrderPushRequest request) { MultiValueMap<String, String> postData = new LinkedMultiValueMap<>(); postData.add("detail", JSON.toJSONString(request)); return flanOrderProxy.push( FlanApiUtils.assembleHeaders(request.getAuthorization()), postData ); }
解说
本地运行,正常!测试环境运行,正常!Mission completed!
Have fun with Java & Spring!
