直奔主題
注意：需要了解整合的可以檢視demo，demo不能喚起支付或分享等功能，因為沒有配置appKey，只能用作程式碼參考。
1、微信支付、登入、分享工具類：WXApiHelper.java
/**
* 微信SDK幫助類
*/
public class WXApiHelper {
private static final String WX_APP_ID = "wx666666";//TODO 微信相關
private static final String WX_APP_SECRET = "66666666666666666";
private static final String WX_SCOPE = "snsapi_userinfo";
private static final String WX_STATE = "sport_dict_wx_login";
private static final String WX_GRANT_TYPE = "authorization_code";
private static final String WX_PACKAGE_VALUE = "Sign=WXPay";
private static WXApiHelper mHelper;
private final IWXAPI mWxApi;
/**
* APP.getInstance() 為Application的context
*/
private WXApiHelper() {
mWxApi = WXAPIFactory.createWXAPI(APP.getInstance(), WX_APP_ID, false);
mWxApi.registerApp(WX_APP_ID);
}
public static WXApiHelper get() {
if (mHelper == null) {
mHelper = new WXApiHelper();
}
return mHelper;
}
/**
* 微信登入
*/
public void doWxLogin() {
final SendAuth.Req req = new SendAuth.Req();
req.scope = WX_SCOPE;
req.state = WX_STATE;
mWxApi.sendReq(req);
}
/**
* 微信支付
*
* @param payInfo 支付相關資訊，需要從自己的伺服器獲取
*/
public void doWxPay(PayInfo payInfo) {
PayReq req = new PayReq();
req.appId = WX_APP_ID;
req.partnerId = payInfo.getPartnerid();
req.prepayId = payInfo.getPrepayid();
req.nonceStr = payInfo.getNoncestr();
req.timeStamp = payInfo.getTimestamp();
req.packageValue = WX_PACKAGE_VALUE;
req.sign = payInfo.getSign();
mWxApi.sendReq(req);
}
/**
* 微信分享url給朋友
*
* @param title 標題
* @param description 內容
* @param url 分享的url
*/
public void doShareUrlToWeChat(String title, String description, String url) {
doShareUrl(title, description, url, SendMessageToWX.Req.WXSceneSession);
}
/**
* 微信分享url到朋友圈
* @param title 標題
* @param description 內容
* @param url 分享的url
*/
public void doShareUrlToTimeline(String title, String description, String url) {
doShareUrl(title, description, url, SendMessageToWX.Req.WXSceneTimeline);
}
private void doShareUrl(String title, String description, String url, int scene) {
WXWebpageObject webpage = new WXWebpageObject();
webpage.webpageUrl = url;
WXMediaMessage msg = new WXMediaMessage(webpage);
msg.title = title;
msg.description = description;
//Bitmap thumbBmp = BitmapFactory.decodeResource(getResources(), R.drawable.send_music_thumb);
//msg.thumbData = Util.bmpToByteArray(thumbBmp, true);
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = "webpage";
req.message = msg;
req.scene = scene;
//req.userOpenId = getOpenId();
mWxApi.sendReq(req);
}
//TODO 其他分享功能可以寫到這裡
public void handleIntent(Intent intent, IWXAPIEventHandler handler) {
mWxApi.handleIntent(intent, handler);
}
}
2、實體類PayInfo.java
/**
* 支付訂單資訊 (微信)
*/
public class PayInfo {
//微信相關資訊
private String return_code;//返回代號
private String return_msg;//
private String appid;//應用ID
private String mch_id;//
private String noncestr;//隨機字串
private String sign;//簽名
private String result_code;//結果代號
private String prepayid;//預支付交易會話ID
private String trade_type;//交易型別
private String partnerid;//商戶號
private String timestamp;//時間戳
//Getter 和 setter 方法這裡就忽略不寫
}
3、呼叫
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
private void doWeChatPay() {
final PayInfo payInfo = new PayInfo();
//TODO 實際的PayInfo需要調自己的伺服器獲取相關資訊
WXApiHelper.get().doWxPay(null);
}
private void doWeChatShare() {
WXApiHelper.get().doShareUrlToWeChat("活動", "這是一個公益活動", "公益活動的網頁連結");
}
private void doWeChatLogin() {
WXApiHelper.get().doWxLogin();
}
}
4、支付回撥WXPayEntryActivity.java
public class WXPayEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WXApiHelper.get().handleIntent(getIntent(), this);
}
@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp baseResp) {
final int type = baseResp.getType();
if (ConstantsAPI.COMMAND_PAY_BY_WX == type) {
switch (baseResp.errCode) {
case BaseResp.ErrCode.ERR_OK:
//TODO 支付成功
break;
case BaseResp.ErrCode.ERR_COMM:
Toast.makeText(this, "支付發生錯誤", Toast.LENGTH_LONG).show();
finish();
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
Toast.makeText(this, "已取消", Toast.LENGTH_LONG).show();
finish();
break;
default:
Toast.makeText(this, "錯誤碼：" + baseResp.errCode, Toast.LENGTH_LONG).show();
finish();
break;
}
}
}
}
5、分享和登入回撥WXEntryActivity.java
public class WXEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WXApiHelper.get().handleIntent(getIntent(), this);
}
@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp baseResp) {
final int type = baseResp.getType();
if (ConstantsAPI.COMMAND_SENDAUTH == type) {//登入
switch (baseResp.errCode) {
case BaseResp.ErrCode.ERR_OK:
final String code = ((SendAuth.Resp) baseResp).code;
getWxLoginInfo(code);
break;
case BaseResp.ErrCode.ERR_AUTH_DENIED:
Toast.makeText(this, "拒絕授權微信登入", Toast.LENGTH_LONG).show();
finish();
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
Toast.makeText(this, "已取消", Toast.LENGTH_LONG).show();
finish();
break;
default:
Toast.makeText(this, "錯誤碼：" + baseResp.errCode, Toast.LENGTH_LONG).show();
finish();
break;
}
} else if (ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX == type) {//分享
finish();
}
}
private void getWxLoginInfo(String code) {
//TODO 通過微信SDK返回的code，請求自己的伺服器獲取使用者資訊。
}
}
