一、支付寶支付
1. 支付寶支付流程圖
2. 集成前准備
- 去螞蟻金服注冊應用獲取appKey等信息
- 創建應用，添加APP支付功能
- 找到APP支付開發文檔，下載 SDK&Demo
3. 開始集成
1、導入Demo中需要用到的Jar包
2、配置AndroidManifest.xml(這里直接放常用的權限)
<!--所需權限--> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_LOGS" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <!--廣播跳轉--> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!--百度地圖--> <!--百度地圖權限--> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /> <!--Mob分享--> <uses-permission android:name="android.permission.GET_TASKS" /> <!-- 短信驗證登陸功能需要添加次權限來自動填充驗證碼，用不到可以去掉 --> <uses-permission android:name="android.permission.RECEIVE_SMS" /> <uses-permission android:name="android.permission.READ_SMS" /> <!--微信支付權限--> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> <!--支付寶支付權限--> <!-- 安卓讀寫sd權限 --> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
支付回調
<!--支付寶支付--> <!-- 支付寶H5頁面支付用的 --> <activity android:name="com.alipay.sdk.app.H5PayActivity" android:configChanges="orientation|keyboardHidden|navigation" android:exported="false" android:screenOrientation="behind" /> <!-- 支付寶App支付頁面用的 --> <activity android:name="com.alipay.sdk.auth.AuthActivity" android:configChanges="orientation|keyboardHidden|navigation" android:exported="false" android:screenOrientation="behind" />
3、請求后台接口拿到簽過名的信息(appKey,訂單信息等等)，這里我獲取數據，是直接給后台傳遞的商品id，如果有的需要商品數量直接給傳給后台，后台根據id查詢出商品的信息，然后返回給前台所需要的支付參數。
支付寶返回參數用例(開始集成的時候看過好多博客都沒有返回參數數據結構，結果一臉懵逼，在這里貼出，未加密之前的0.0)：
格式化后的：
{ "msg":"success", "code":200, "data":"alipay_sdk=alipay-sdk-java-dynamicVersionNo&app_id=你們申請的app_id&biz_content=%7B%22out_trade_no%22%3A%22HY201806210002%22%2C%22product_code%22%3A%22QUICK_MSECURITY_PAY%22%2C%22subject%22%3A%22%E4%BC%98%E9%93%BA%E4%BC%9A%E5%91%98%E6%9C%8D%E5%8A%A1%E8%B4%B9%22%2C%22total_amount%22%3A%220.01%22%7D&charset=UTF-8&format=json&method=alipay.trade.app.pay¬ify_url=http%3A%2F%2F你們的回調地址%2FaliPayCallBack%2FcallBack&sign=buipaoj2F8xl5XCAUVoJz%2Fbh8dHbaoRmdzoAEzqKRJqtZATT4bfFdzSHurAAL5C5gvntFrDTGHgNRGw%2BNZBtG4DfetOzcpHMAyjslrmUIMIr1YGC7Qya04mFBCh%2B0UIa1E7RISZWSbIVCHpZISknNgF2oTuTixNosXvDXzkGYGBUoaxdh1f6%2F%2Bw9lqKz7mkhsUc0x8lCeJHw4MnTS4gSLU%2BDmOCk6Tkiwb4Yv4Mz%2F6j7XReeagfX7qxs5qbObnnPX%2FFmu9T%2BF0LwJaPxr5Xys8kr8E4bhd4f7Y5FimXiw%2BG7EFkY0I69boiRob7zo%2BbWQ%2F53TAMeTXX5RJybEdXhrA%3D%3D&sign_type=RSA2×tamp=2018-06-21+14%3A11%3A40&version=1.0", "status":"0" }
后台返回信息之后接下來就是我們的事情了，調起支付寶進行支付
/*支付寶測試*/ private void testZfbPay(final String key, final String value) { StringRequest stringRequest = new StringRequest(Request.Method.POST, NetWorkUrl.ZFBPAY, new Response.Listener<String>() { @RequiresApi(api = Build.VERSION_CODES.M) @Override public void onResponse(String s) { Log.e("GoPayOrderActivity", "-------getJson2-------" + s.toString()); /*判斷code*/ String code = (JSONObject.parseObject(s.toString()).getString("code")); if (code.equals("200")) { String orderInfo = (JSONObject.parseObject(s.toString()).getString("data"));//返回的信息 MyALipayUtils.ALiPayBuilder builder = new MyALipayUtils.ALiPayBuilder(); builder.build().toALiPay(GoPayOrderActivity.this, orderInfo); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError volleyError) { } }) { @Override public Map<String, String> getParams() throws AuthFailureError { Log.e("GoPayOrderActivity", "getParams:-----------------> " + userEntity.getPhone()); Map<String, String> map = new HashMap<String, String>(); map.put("account", userEntity.getPhone()); map.put(key, value); map.put("token", userEntity.getToken()); return map; } @Override public Map<String, String> getHeaders() throws AuthFailureError { HashMap<String, String> headers = new HashMap<String, String>(); if (userEntity.getToken().equals("") && userEntity != null) { headers.put("Authorization", userEntity.getToken()); } return headers; } }; /*設置請求一次*/ stringRequest.setRetryPolicy( new DefaultRetryPolicy( 5000,//默認超時時間，應設置一個稍微大點兒的，例如本處的500000 DefaultRetryPolicy.DEFAULT_MAX_RETRIES,//默認最大嘗試次數 DefaultRetryPolicy.DEFAULT_BACKOFF_MULT ) ); AppApplication.getHttpQueues().add(stringRequest);/*請求數據*/ }
MyALipayUtils.java這個類直接copy使用就可以

完成上述操作，你的app在螞蟻金服后台應用上線之后，就完全可以調用支付了，但是在開發階段，應用沒有上線，你是不能進行調試的，所以支付寶有沙箱模式可以進行調試，ios沒有喲
進行沙箱調試在Activity的的onCreate()方法中添加
EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);//支付寶沙箱環境，正式需注釋
別忘了讓你們后台把appKey等信息換成沙箱的，然后測試支付的時候，需要下載一個沙箱支付寶，這個你可以隨意支付，附上鏈接
沙箱首頁：https://sandbox.alipaydev.com/user/accountDetails.htm?currentBar=1
App支付接入文檔:https://docs.open.alipay.com/204/105051
沙箱錢包下載：
調試都沒有問題之后，就可以在螞蟻金服開發者平台進行應用上線，然后沙箱代碼就可以注釋了，這樣支付寶支付就接入完成
