我检查了下 参数已经完全按照文档传的了，name字段也按官方的函数用平台证书加密了

实在找不出问题了，网上也找不到类似的demo。

报错为：应答的状态码不为200-299。status code[400]

相关代码如下

@Autowired
private CertificatesManagerService certificatesManagerService;

WechatConfig config =  SpringUtils.getBean(WechatConfig.class);

HttpPost httpPostAdd = new HttpPost("https://api.mch.weixin.qq.com/v3/profitsharing/receivers/add");

@Override
public void profitSharing(SharingDto param) throws Exception {
Verifier verifier = certificatesManagerService.getCertificate();
// 构造httpclient
httpClient = WechatPayHttpClientBuilder.create()
        .withMerchant(config.getMchId(), config.getMchSerialNo(), config.getPrivateKey())
        .withValidator(new WechatPay2Validator(verifier))
        .build();;



httpPostAdd.addHeader("Accept", "application/json");
httpPostAdd.addHeader("Content-type","application/json; charset=utf-8");
httpPostAdd.addHeader("Wechatpay-Serial",config.getMchSerialNo());


ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectMapper objectMapper = new ObjectMapper();


//敏感信息 分账的商户名称加密
String name = rsaEncryptOAEP(config.getName(),verifier.getValidCertificate());

//构造请求参数
ObjectNode rootNodeAdd = objectMapper.createObjectNode();
rootNodeAdd.put("sub_mchid", config.getPaymchid()) //子商户号
        .put("appid",config.getAppId()) //appid
        .put("type","MERCHANT_ID")
        .put("name",name)
        .put("account", config.getMchId()) //分润的服务商号
        .put("relation_type", "SERVICE_PROVIDER")
        .put("custom_relation", "代理商"); 



objectMapper.writeValue(bos, rootNodeAdd);
httpPostAdd.setEntity(new StringEntity(bos.toString("UTF-8"), "UTF-8"));


CloseableHttpResponse response = httpClient.execute(httpPostAdd);

}
