Java对返回参数进行处理
根据返回参数格式获取其中的值
1.得到ResponseEntity<String> responseEntity对象
import org.springframework.http.ResponseEntity;
得到ResponseEntity<String> responseEntity对象
<200, { "code":0, "data":{ "list":[ { "amount":0, "auditTime":"", "channelType":"", "createTime":"2019-08-13 17:01:55", "creditStatus":"", "edit":true, "fundsStatus":"", "id":372, "idNo":"", "lendRequestId":0, "mobile":"13289989000", "name":"客户姓名", "soinsStatus":"", "state":0, "stateText":"", "viewStateText":0 } ] }, "mask":"251eeedb-e214-47c6-aa0c-3eb6c7b67aa0", "msg":"success", "timestamp":1566089672 } ,{Server=[Tengine/2.1.1], Date=[Sun, 18 Aug 2019 00:54:32 GMT], Content-Type=[application/json;charset=UTF-8], Content-Length=[412], Connection=[keep-alive]}>
2.根据ResponseEntity<String> responseEntity对象
获取body部分,body为json格式字符串
String content = responseEntity.getBody();
content输出如下:
{ "code":0, "data":{ "list":[ { "amount":0, "auditTime":"", "channelType":"", "createTime":"2019-08-13 17:01:55", "creditStatus":"", "edit":true, "fundsStatus":"", "id":372, "idNo":"", "lendRequestId":0, "mobile":"13243345566", "name":"客户姓名", "soinsStatus":"", "state":0, "stateText":"", "viewStateText":0 } ] }, "mask":"251eeedb-e214-47c6-aa0c-3eb6c7b67aa0", "msg":"success", "timestamp":1566089672 }
3.获取list中的id,name,mobile等字段值
- 3.1将json字符串转化为json对象
//将json字符串转化为json对象 JSONObject json = JSONObject.parseObject(content); { "msg":"success", "code":0, "data":{ "list":[ { "amount":0, "soinsStatus":"", "viewStateText":0, "edit":true, "mobile":"12324435555", "channelType":"", "creditStatus":"", "fundsStatus":"", "idNo":"", "auditTime":"", "createTime":"2019-08-13 17:01:55", "stateText":"", "name":"客户姓名", "id":372, "lendRequestId":0, "state":0 } ] }, "mask":"251eeedb-e214-47c6-aa0c-3eb6c7b67aa0", "timestamp":1566089672 }
- 3.2 取出data部分
//取出data部分对象 JSONObject data = json.getJSONObject("data"); { "list":[ { "amount":0, "soinsStatus":"", "viewStateText":0, "edit":true, "mobile":"13234444555", "channelType":"", "creditStatus":"", "fundsStatus":"", "idNo":"", "auditTime":"", "createTime":"2019-08-13 17:01:55", "stateText":"", "name":"客户姓名", "id":372, "lendRequestId":0, "state":0 } ] }
- 3.3 data中包含有数组
list中的内容带有中括号[],所以要转化为JSONArray类型的对象
//转化为JSONArray类型的对象 JSONArray jsonArray = data.getJSONArray("list"); [ { "amount":0, "soinsStatus":"", "viewStateText":0, "edit":true, "mobile":"13234444555", "channelType":"", "creditStatus":"", "fundsStatus":"", "idNo":"", "auditTime":"", "createTime":"2019-08-13 17:01:55", "stateText":"", "name":"客户姓名", "id":372, "lendRequestId":0, "state":0 } ]
- 3.4 若为多个数组
jsonArray.getJSONObject(index)
//随机选取一个数组 JSONObject idInfo = jsonArray.getJSONObject(randomInteger(0,jsonArray.size())); String id=idInfo.getString("id");
java后端常用返回参数,复制粘贴直接用
@Data public class CommonResult<T> { /** * 结果 */ private T data; /** * 状态码 */ private Integer code; /** * 状态码描述 */ private String message; public CommonResult() {} public CommonResult(Integer code, String message) { this.code = code; this.message = message; } protected CommonResult(Integer code, String message, T data) { this.code = code; this.message = message; this.data = data; } /** * 成功返回结果 * */ public static <T> CommonResult<T> success() { return new CommonResult<>(ExceptionCode.SUCCESS.getCode(), ExceptionCode.SUCCESS.getMessage()); } /** * 成功返回结果 * * @param data 获取的数据 */ public static <T> CommonResult<T> success(T data ) { return new CommonResult<>(ExceptionCode.SUCCESS.getCode(), ExceptionCode.SUCCESS.getMessage(), data); } /** * 成功返回结果 * * @param data 获取的数据 * @param message 提示信息 */ public static <T> CommonResult<T> success(T data, String message) { return new CommonResult<>(ExceptionCode.SUCCESS.getCode(), message, data); } /** * 失败返回结果 * @param errorCode 错误码 * @param message 错误信息 */ public static <T> CommonResult<T> failed(Integer errorCode, String message) { return new CommonResult<>(errorCode, message, null); } /** * 失败返回结果 * @param message 提示信息 */ public static <T> CommonResult<T> failed(String message) { return new CommonResult<>(ExceptionCode.FAILED.getCode(), message, null); } /** * 权限过期 */ public static <T> CommonResult<T> unauthorized() { return new CommonResult<>(ExceptionCode.FAILED.getCode(), "用户登录已过期,请重新登录!", null); } }
public class ExceptionCode { public static final ExceptionCode SUCCESS = new ExceptionCode(200, "操作成功"); public static final ExceptionCode FAILED = new ExceptionCode(500, "系统异常"); private int code; private String message; public ExceptionCode(int code, String message) { this.code = code; this.message= message; } public ExceptionCode(String message) { this.message = message; } public Integer getCode() { return this.code; } public String getMessage() { return this.message; } }
