微信支付與微信登錄 依賴一樣
implementation 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'
微信支付權限
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
在支付的Activity里面的布局xml寫入一個Button
<Button
android:id="@+id/zf_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="支付"/>
在支付的Activity里面寫一個加密的方法
/**
* MD5加密
*
* @param sourceStr
* @return
*/
public static String MD5(String sourceStr) {
String result = "";
try {
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(sourceStr.getBytes());
byte b[] = md.digest();
int i;
StringBuffer buf = new StringBuffer("");
for (int offset = 0; offset < b.length; offset++) {
i = b[offset];
if (i < 0)
i += 256;
if (i < 16)
buf.append("0");
buf.append(Integer.toHexString(i));
}
result = buf.toString();
} catch (NoSuchAlgorithmException e) {
System.out.println(e);
}
return result;
}
在Button點擊事件里面請求資料
StringBuilder sb = new StringBuilder();
HashMap<String, Object> map = new HashMap<>();
map.put("commodityId", 1001);
result = "";
sb.append("1719");
sb.append(1001);
sb.append("tech");
result = sb.toString();
String str = MD5(result);
map.put("sign", str);
//網路請求
RetrofitMananger.getInstance().create().getCj(MyUrl.CJ,map)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<ResponseBody>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(ResponseBody responseBody) {
try {
String string = responseBody.string();
CJBean cjBean = new Gson().fromJson(string, CJBean.class);
if (cjBean.getStatus().equals("0000")){
//網路請求購買
HashMap<String, Object> map1 = new HashMap<>();
map1.put("orderId", "20201201103009829");
map1.put("payType",1);
RetrofitMananger.getInstance().create().getPay(MyUrl.ZF,map1)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<ResponseBody>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(ResponseBody responseBody) {
try {
String string1 = responseBody.string();
ZFBean zfBean = new Gson().fromJson(string1, ZFBean.class);
Log.i("TAG", string1);
if (zfBean.getStatus().equals("0000")){
PayReq req = new PayReq();
req.appId = zfBean.getAppId();
req.nonceStr = zfBean.getNonceStr();
req.partnerId = zfBean.getPartnerId();
req.prepayId = zfBean.getPrepayId();
req.sign = zfBean.getSign();
req.timeStamp = zfBean.getTimeStamp();
req.packageValue = zfBean.getPackageValue();
//去調微信
WXUtils.reg(ZFActivity.this).sendReq(req);
}
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onError(Throwable e) {
}
@Override
public void onComplete() {
}
});
}
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onError(Throwable e) {
}
@Override
public void onComplete() {
}
});
map.put(“commodityId”, 1001);這個里面的1001是查詢所有會員商品里面的commodityId
sb.append(“1719”);1719是userId
//創建
@POST
Observable<ResponseBody> getCj(@Url String url, @QueryMap HashMap<String,Object> map);
///支付
@POST
Observable<ResponseBody> getPay(@Url String url, @QueryMap HashMap<String,Object> map);
第一層：
用用購買VIP里面的 map1.put(“orderId”, “20201201103009829”);
是下面列印出來的
第二層是支付
將工具類放到model里面
老樣子在wxapi下新建WXPayEntryActivity
以下是代碼：
public class WXPayEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
private IWXAPI iwxapi;
private static String APP_ID = "wxb3852e6a6b7d9516";
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// // 隱藏狀態欄
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
//接收到分享以及登錄的intent傳遞handleIntent方法，處理結果
iwxapi = WXAPIFactory.createWXAPI(this, APP_ID, false);
iwxapi.handleIntent(getIntent(), this);
}
@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp baseResp) {
if (baseResp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
switch (baseResp.errCode) {
case BaseResp.ErrCode.ERR_OK:
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(WXPayEntryActivity.this, "成功", Toast.LENGTH_SHORT).show();
Log.e("dj", "支付成功");
WXPayEntryActivity.this.finish();
}
});
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
Toast.makeText(WXPayEntryActivity.this, "取消支付", Toast.LENGTH_SHORT).show();
Log.e("dj", "用戶取消支付");
WXPayEntryActivity.this.finish();
break;
default:
break;
}
}
}
}
清單注冊
<activity android:name=".wxapi.WXPayEntryActivity"/>
