特约商户进件-查询申请单状态API,应答的状态码不为200-299。status code[400]

接口调用代码:

CloseableHttpClient httpClient = WxHttpClient.createHttpClient();
HttpGet httpGet = new HttpGet("https://api.mch.weixin.qq.com/v3/applyment4sub/applyment/business_code/" + businessCode);
httpGet.addHeader("Accept", "application/json");
httpGet.addHeader("Content-type", "application/json; charset=utf-8");
CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity entity = response.getEntity();
WxAuthStatusResponse res = JSONObject.parseObject(EntityUtils.toString(entity), WxAuthStatusResponse.class);


工具类代码:

public class WxHttpClient {
    // 设置VX证书默认参数
    // 服务商Id
    private static final String merchantId = "163...";
    // API V3密钥
    private static final String apiV3Key = "zL3gprVKrr05...";
    // 证书序列号
    public static final String serialNumber = "2DD9DABDD05...";

    public static CloseableHttpClient createHttpClient() {
        PrivateKey privateKey = createPrivateKey();
        Verifier verifier = createVerifier(privateKey);
        WechatPayHttpClientBuilder builder = WechatPayHttpClientBuilder.create()
                .withMerchant(merchantId, serialNumber, privateKey)
                .withValidator(new WechatPay2Validator(verifier));
        return builder.build();
    }

    public static PrivateKey createPrivateKey() {
        InputStream inputStream = ResourceUtil.getStream("wx_pay/apiclient_key.pem");
        return PemUtil.loadPrivateKey(inputStream);
    }

    public static Verifier createVerifier(PrivateKey privateKey) {
        try {
            CertificatesManager instance = CertificatesManager.getInstance();
            instance.putMerchant(merchantId, new WechatPay2Credentials(
                    merchantId, new PrivateKeySigner(serialNumber, privateKey)), apiV3Key.getBytes(StandardCharsets.UTF_8));
            return instance.getVerifier(merchantId);
        } catch (GeneralSecurityException | NotFoundException | IOException | HttpCodeException e) {
            e.printStackTrace();
        }
        return null;
    }
}

    代码没有问题,实际返回的body:{"code":"PARAM_ERROR","message":"未能找到申请单"}

    不是代码问题
