Java 查询企业基本信息接口实现（企查查）-蒲公英云

因项目需要，系统中需要添加根据企业名称或统一信用代码查询企业信息的功能，所以整合了企查查的查询接口

我将代码稍微改造了一下，仅供参考，如有错误，劳您指出：

@Value("${qichacha.key}")
private String key;
@Value("${qichacha.secret}")
private String secret;
//搜索关键字（公司名、注册号、社会统一信用代码或KeyNo）注：社会组织、香港企业仅支持通过企业名称和KeyNo查询
@Log("企业信息列表")
@ApiOperation(value = "企业信息列表")
@GetMapping(value = "list.do" , produces = "application/json;charset=UTF-8")
public  R pageList(@RequestParam(value = "keyword")String keyword ,HttpServletRequest request) { 
        List<EnterpriseInfoDO> resultList = new ArrayList<>();
        String reqInterNme = "http://api.qichacha.com/ECIV4/Search";
        String paramStr = "keyword="+keyword;
        try { 
            // auth header setting
            HttpHead reqHeader = new HttpHead();
            String[] autherHeader = QiChaChaUtil.RandomAuthentHeader(key,secret);
            reqHeader.setHeader("Token", autherHeader[0]);
            reqHeader.setHeader("Timespan", autherHeader[1]);
            final String reqUri = reqInterNme.concat("?key=").concat(key).concat("&").concat(paramStr).concat("&pageSize=20");
            String tokenJson = HttpHelper.httpGet(reqUri, reqHeader.getAllHeaders());
            JSONObject jsonObject = JSON.parseObject(tokenJson);
            return R.ok().put("result",resultList);
        } catch (Exception e1) { 
            e1.printStackTrace();
            return R.error("查询企业信息失败");
        }
    }
}
