base64加密解密和json处理

step1: 加密和解密

package com.example.textdemo;import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle;
import android.text.TextUtils;
import android.util.Base64;
import android.util.Log;import com.google.gson.Gson;

import com.google.gson.reflect.TypeToken;import java.io.UnsupportedEncodingException;
import java.util.List;public class MainActivity extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);String firstString = "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";/**解析base64   字符串* */String lastString = base64Decode(firstString, "UTF-8");Log.e("TAG", "" + lastString);Gson gson = new Gson();ScanCodeBean mScanCodeBean = gson.fromJson(lastString, ScanCodeBean.class);String webSitString = mScanCodeBean.getWebsit();String equipments = mScanCodeBean.getEquipments();Log.e("TAG", "" + webSitString + "\t" + equipments);/*  差不多完成版本final GsonBuilder gsonBuilder = new GsonBuilder();final Gson gson2 = gsonBuilder.create();ScanCodeDeviceBean[] testCase = gson2.fromJson(equipments, ScanCodeDeviceBean[].class);//        ScanCodeDeviceBean testCase = gson2.fromJson(equipments, ScanCodeDeviceBean.class);String equipmentNote =  testCase[0].getEquipmentNote();Log.e("TAG", "" +equipmentNote);*/List<ScanCodeDeviceBean> scanCodeDeviceBeanList = gson.fromJson(equipments, new TypeToken<List<ScanCodeDeviceBean>>() {}.getType());Log.e("TAG", "" + scanCodeDeviceBeanList);/*   ScanCodeDeviceBean mScanCodeDeviceBean = gson.fromJson(equipments, ScanCodeDeviceBean.class);String equipmentId = mScanCodeDeviceBean.getEquipmentId();Log.e("TAG", "" + equipmentId + "\t");*/}/*** Base64加密字符串** @param content     -- 代加密字符串* @param charsetName -- 字符串编码方式* @return*/private String base64Encode(String content, String charsetName) {if (TextUtils.isEmpty(charsetName)) {charsetName = "UTF-8";}try {byte[] contentByte = content.getBytes(charsetName);return Base64.encodeToString(contentByte, Base64.DEFAULT);} catch (UnsupportedEncodingException e) {e.printStackTrace();}return "";}/*** Base64解密字符串** @param content     -- 待解密字符串* @param charsetName -- 字符串编码方式* @return*/private String base64Decode(String content, String charsetName) {if (TextUtils.isEmpty(charsetName)) {charsetName = "UTF-8";}byte[] contentByte = Base64.decode(content, Base64.DEFAULT);try {return new String(contentByte, charsetName);} catch (UnsupportedEncodingException e) {e.printStackTrace();}return "";}}

step2: 生成json对象

package com.example.textdemo;import android.os.Bundle;
import android.util.Log;import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;import com.google.gson.Gson;import java.util.ArrayList;
import java.util.List;public class HomeActivity extends AppCompatActivity {@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);/**生成json  首先生成list*/List<ScanCodeDeviceBean> scanCodeDeviceBeanList = new ArrayList<>();ScanCodeDeviceBean mScanCodeDeviceBean = new ScanCodeDeviceBean();mScanCodeDeviceBean.setEquipmentId("zcz002103910");mScanCodeDeviceBean.setEquipmentNote("一氧化碳(co)");mScanCodeDeviceBean.setProductId("zcz002");scanCodeDeviceBeanList.add(mScanCodeDeviceBean);Log.e("TAG", "" +scanCodeDeviceBeanList);Gson gson = new Gson();//  List<WellSectionEntity> sectionlist = gson.fromJson(jsonTemp, new TypeToken<List<WellSectionEntity>>(){}.getType());String age =  gson.toJson(scanCodeDeviceBeanList);Log.e("TAG", "" +age);/**list转字符串*/ScanCodeBean mScanCodeBean = new ScanCodeBean();mScanCodeBean.setWebsit("https://mg.mindordz.com/mindor/download_apply?id=96");mScanCodeBean.setDevKey("e62c506ed9aa46c2ab50e0339835efcf");mScanCodeBean.setDevSecret("9a9b16d688174a23a0326949b23e51cb");mScanCodeBean.setUserId("minApp113988");mScanCodeBean.setPlatform("iOS");mScanCodeBean.setModel("iPhone");mScanCodeBean.setEquipments(age);mScanCodeBean.setType("share");mScanCodeBean.setDevices("zcz002103910");mScanCodeBean.setNickName("");mScanCodeBean.setCreateTime(1650589777);String name =  gson.toJson(mScanCodeBean);Log.e("TAG", "" +name);}
}

step3:

package com.example.textdemo;public class ScanCodeBean{/*** websit : https://mg.mindordz.com/mindor/download_apply?id=96* devKey : e62c506ed9aa46c2ab50e0339835efcf* devSecret : 9a9b16d688174a23a0326949b23e51cb* userId : minApp113988* platform : iOS* model : iPhone* equipments : [{"equipmentId":"zcz002103910","equipmentNote":"一氧化碳(co)","productId":"zcz002"}]* type : share* devices : zcz002103910* nickName :* createTime : 1650589777*/private String websit;private String devKey;private String devSecret;private String userId;private String platform;private String model;private String equipments;private String type;private String devices;private String nickName;private int createTime;public String getWebsit() {return websit;}public void setWebsit(String websit) {this.websit = websit;}public String getDevKey() {return devKey;}public void setDevKey(String devKey) {this.devKey = devKey;}public String getDevSecret() {return devSecret;}public void setDevSecret(String devSecret) {this.devSecret = devSecret;}public String getUserId() {return userId;}public void setUserId(String userId) {this.userId = userId;}public String getPlatform() {return platform;}public void setPlatform(String platform) {this.platform = platform;}public String getModel() {return model;}public void setModel(String model) {this.model = model;}public String getEquipments() {return equipments;}public void setEquipments(String equipments) {this.equipments = equipments;}public String getType() {return type;}public void setType(String type) {this.type = type;}public String getDevices() {return devices;}public void setDevices(String devices) {this.devices = devices;}public String getNickName() {return nickName;}public void setNickName(String nickName) {this.nickName = nickName;}public int getCreateTime() {return createTime;}public void setCreateTime(int createTime) {this.createTime = createTime;}
}

step4:

package com.example.textdemo;public class ScanCodeDeviceBean {/*** equipmentId : zcz002103910* equipmentNote : 一氧化碳(co)* productId : zcz002*/private String equipmentId;private String equipmentNote;private String productId;public String getEquipmentId() {return equipmentId;}public void setEquipmentId(String equipmentId) {this.equipmentId = equipmentId;}public String getEquipmentNote() {return equipmentNote;}public void setEquipmentNote(String equipmentNote) {this.equipmentNote = equipmentNote;}public String getProductId() {return productId;}public void setProductId(String productId) {this.productId = productId;}
}
