一、支付宝支付
1. 支付宝支付流程图
2. 集成前准备
- 去蚂蚁金服注册应用获取appKey等信息
- 创建应用，添加APP支付功能
- 找到APP支付开发文档，下载 SDK&Demo
3. 开始集成
1、导入Demo中需要用到的Jar包
2、配置AndroidManifest.xml(这里直接放常用的权限)
<!--所需权限-->
<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" /> <!--广播跳转-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!--百度地图-->
<!--百度地图权限-->
<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" />
<!-- 短信验证登陆功能需要添加次权限来自动填充验证码，用不到可以去掉 -->
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" /> <!--微信支付权限-->
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> <!--支付宝支付权限-->
<!-- 安卓读写sd权限 -->
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
支付回调
<!--支付宝支付-->
<!-- 支付宝H5页面支付用的 -->
<activity
android:name="com.alipay.sdk.app.H5PayActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind" />
<!-- 支付宝App支付页面用的 -->
<activity
android:name="com.alipay.sdk.auth.AuthActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind" />
3、请求后台接口拿到签过名的信息(appKey,订单信息等等)，这里我获取数据，是直接给后台传递的商品id，如果有的需要商品数量直接给传给后台，后台根据id查询出商品的信息，然后返回给前台所需要的支付参数。
支付宝返回参数用例(开始集成的时候看过好多博客都没有返回参数数据结构，结果一脸懵逼，在这里贴出，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=你们申请的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你们的回调地址%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来就是我们的事情了，调起支付宝进行支付
/*支付宝测试*/
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()); /*判断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;
} };
/*设置请求一次*/
stringRequest.setRetryPolicy(
new DefaultRetryPolicy(
5000,//默认超时时间，应设置一个稍微大点儿的，例如本处的500000
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,//默认最大尝试次数
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
)
);
AppApplication.getHttpQueues().add(stringRequest);/*请求数据*/
}
MyALipayUtils.java这个类直接copy使用就可以

完成上述操作，你的app在蚂蚁金服后台应用上线之后，就完全可以调用支付了，但是在开发阶段，应用没有上线，你是不能进行调试的，所以支付宝有沙箱模式可以进行调试，ios没有哟
进行沙箱调试在Activity的的onCreate()方法中添加
EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);//支付宝沙箱环境，正式需注释
别忘了让你们后台把appKey等信息换成沙箱的，然后测试支付的时候，需要下载一个沙箱支付宝，这个你可以随意支付，附上链接
沙箱首页：https://sandbox.alipaydev.com/user/accountDetails.htm?currentBar=1
App支付接入文档:https://docs.open.alipay.com/204/105051
沙箱钱包下载：
调试都没有问题之后，就可以在蚂蚁金服开发者平台进行应用上线，然后沙箱代码就可以注释了，这样支付宝支付就接入完成
