解決方案

版本一?

package com.tntxia.geography.util;import java.util.Map; import com.alibaba.fastjson.JSON;public class JSONPParser {public static Map parseJSONP(String jsonp){int startIndex = jsonp.indexOf("(");int endIndex = jsonp.lastIndexOf(")");String json = jsonp.substring(startIndex+1, endIndex);System.out.println(json);return JSON.parseObject(json);}public static void main(String[] args){Map map = parseJSONP("jsonp_test({})");}}

版本二?

package com.tntxia.geography.util;import java.util.Map; import com.alibaba.fastjson.JSON;public class JSONPParser {public void Map parseJSONP(String jsonp){int startIndex = jsonp.indexOf("(");int endIndex = jsonp.lastIndexOf(")");String json = jsonp.substring(startIndex+1, endIndex);System.out.println(json);CallBack callBack = JSONObject.parseObject(json, CallBack.class);System.out.println(callBack);}public static void main(String[] args){parseJSONP("jsonp_test({})");}}

?CallBack類?

package cn.edu.zstu.myzstu.spyder.ezstu;/*** @Author ShenTuZhiGang* @Version 1.0.0* @Date 2020-07-12 15:28*/ class CallBack{public String getErrorCode() {return errorCode;}public void setErrorCode(String errorCode) {this.errorCode = errorCode;}private String errorCode;private String status;private String errorMsg;private String accessToken;@Overridepublic String toString() {return "CallBack{" +"errorCode='" + errorCode + '\'' +", status='" + status + '\'' +", errorMsg='" + errorMsg + '\'' +", accessToken='" + accessToken + '\'' +", url='" + url + '\'' +'}';}public String getAccessToken() {return accessToken;}public void setAccessToken(String accessToken) {this.accessToken = accessToken;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}private String url;public String getStatus() {return status;}public void setStatus(String status) {this.status = status;}public String getErrorMsg() {return errorMsg;}public void setErrorMsg(String errorMsg) {this.errorMsg = errorMsg;} }
