Java 查询企业基本信息接口实现（企查查）

痛定思痛。 2023-06-26 08:25 27阅读 0赞

## 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");
 		}
 	}
 }
