微信小程序 根据银行卡号查银行信息

微信小程序 根据银行卡号查银行信息

根据银行卡号查银行信息

微信官方接口文档：根据卡号查银行信息

access_token获取方式：微信官方接口文档

实体类

需要引入lombok依赖
否则手写getter ，setter 方法

import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

@Getter
@Setter
@NoArgsConstructor
public class BankInfoResVo {private String bank_code;private Long bank_id;private String bank_name;private Boolean need_branch;private String account_bank;}

@Getter
@Setter
@NoArgsConstructor
public class BankResVo {private List<BankInfoResVo> data;private Integer totalCount;private Integer errcode;private String errmsg;
}

接口实现

传入小程序全局唯一后台接口调用凭据access_token、银行卡号carNo
将微信接口返回的结果转换成实体类返回到前端

/*** 获取银行信息* @param accessToken   小程序全局唯一后台接口调用凭据* @param cardNo   银行卡号* @return*/
public BankResVo bankInfoRequest(String accessToken, String cardNo) {BankResVo bankResVo = new BankResVo();// 构造请求URLString requestUrl = "=" + accessToken;JSONObject jsonParams = new JSONObject();jsonParams.put("account_number", cardNo);// 创建 CloseableHttpClient 实例CloseableHttpClient httpClient = ateDefault();// 创建 POST 请求HttpPost post = new HttpPost(requestUrl);try {// 设置请求头post.setHeader("Content-Type", "application/json");// 设置请求体StringEntity entity = new String(), ContentType.APPLICATION_JSON);post.setEntity(entity);// 发送请求并获取响应CloseableHttpResponse response = ute(post);int statusCode = StatusLine().getStatusCode();if (statusCode == 200) {// 解析响应HttpEntity responseEntity = Entity();String responseString = String(responseEntity);//log.info("success,return body = " + responseString );// 解析 JSON 响应JSONObject jsonResponse = new JSONObject(responseString);JSONArray data = JSONArray("data");// 将 JSON 数组转换为实体类列表ObjectMapper mapper = new ObjectMapper();List<BankInfoResVo> bankInfoList = String(), new TypeReference<List<BankInfoResVo>>() {});bankResVo.setData(bankInfoList);bankResVo.Int("total_count"));bankResVo.Int("errcode"));bankResVo.String("errmsg"));} else {throw new IOException("request failed");}} catch (IOException e) {e.printStackTrace();}return bankResVo;
}
