1、支付寶支付

1. 支付寶支付流程圖

2. 集成前準備

去螞蟻金服註冊應用獲取appKey等信息
建立應用，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

　　一、導入Demo中須要用到的Jar包html

　　二、配置AndroidManifest.xml(這裏直接放經常使用的權限)java

 <!--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" />
    <!-- 短信驗證登錄功能須要添加次權限來自動填充驗證碼，用不到能夠去掉 -->
    <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android

<!--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" />

三、請求後臺接口拿到簽過名的信息(appKey,訂單信息等等)，這裏我獲取數據，是直接給後臺傳遞的商品id，若是有的須要商品數量直接給傳給後臺，後臺根據id查詢出商品的信息，而後返回給前臺所須要的支付參數。ios

　　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，在這裏貼出，未加密以前的0.0)：express

格式化後的：json

{
    "msg":"success",
    "code":200,
    "data":"alipay_sdk=alipay-sdk-java-dynamicVersionNo&app_id=大家申請的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&notify_url=http%3A%2F%2F大家的回調地址%2FaliPayCallBack%2FcallBack&sign=buipaoj2F8xl5XCAUVoJz%2Fbh8dHbaoRmdzoAEzqKRJqtZATT4bfFdzSHurAAL5C5gvntFrDTGHgNRGw%2BNZBtG4DfetOzcpHMAyjslrmUIMIr1YGC7Qya04mFBCh%2B0UIa1E7RISZWSbIVCHpZISknNgF2oTuTixNosXvDXzkGYGBUoaxdh1f6%2F%2Bw9lqKz7mkhsUc0x8lCeJHw4MnTS4gSLU%2BDmOCk6Tkiwb4Yv4Mz%2F6j7XReeagfX7qxs5qbObnnPX%2FFmu9T%2BF0LwJaPxr5Xys8kr8E4bhd4f7Y5FimXiw%2BG7EFkY0I69boiRob7zo%2BbWQ%2F53TAMeTXX5RJybEdXhrA%3D%3D&sign_type=RSA2&timestamp=2018-06-21+14%3A11%3A40&version=1.0",
    "status":"0"
}

後臺返回信息以後接下來就是咱們的事情了，調起支付寶進行支付api

 /*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*/
    }

完成上述操做，你的app在螞蟻金服後臺應用上線以後，就徹底能夠調用支付了，可是在開發階段，應用沒有上線，你是不能進行調試的，因此支付寶有沙箱模式能夠進行調試，ios沒有喲網絡

進行沙箱調試在Activity的的onCreate()方法中添加數據結構

EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);//支付寶沙箱環境，正式需註釋

別忘了讓大家後臺把appKey等信息換成沙箱的，而後測試支付的時候，須要下載一個沙箱支付寶，這個你能夠隨意支付，附上連接

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：

調試都沒有問題以後，就能夠在螞蟻金服開發者平臺進行應用上線，而後沙箱代碼就能夠註釋了，這樣支付寶支付就接入完成
