本文章仅作为个人笔记
截止发文在网上找了一圈支付宝登录的，大部分都是照搬官方的demo，没什么实际用处，官方的demo大家应该都看过了，对于Android来讲问题应该不大，后台就gg了，这里主写后台与Android对接心得。
因为实在被支付宝折腾的厉害，所以这里就不写什么注册处签约什么的流程了，心累，上些干货（代码），作为中国人自己的开放平台，文档还整理成这个样子需要自己琢磨代码的估计也就这一家了。也有可能是楼主自己语文或者检索能力不过关哦，如果看客发现有不规范或者不对的地方还望指出，这里先谢过了。

IOS端
-
引入官方库(于Podfile文件加入如下内容并运行 pod install)
pod 'AlipaySDK-iOS' -
于头文件添加如下内容，不知道什么是头文件的建议参考支付宝IOS官方接入文档
#import <AlipaySDK/AlipaySDK.h> 添加 URL Schemes ，设置为aliauth 并设置值为某一唯一值，如 包名.aliauth。设置为alipay 并设置值为某一唯一值，如 包名.alipay。
与Localizable.strings 添加 "aliauthback" = ""//这里需要保持与上面的URL Schemes aliauth值一致。添加 "alipayback" = ""//这里需要保持与上面的URL Schemes alipay值一致。
-
创建AliPayUtils工具文件
class AliPayUtils { private static var aliAuthBack: AliPayBack? private static var aliPayBack: AliPayBack? static func login(signStr: String, aliAuthBack: AliPayBack?) { AliPayUtils.aliAuthBack = aliAuthBack AlipaySDK().auth_V2(withInfo: signStr, fromScheme: NSLocalizedString("aliauthback", comment: ""), callback: { (resp) in loginBack(resultDic: resp as! [NSObject: AnyObject]) }) } static func loginBack(resultDic: [NSObject: AnyObject]) { if let Alipayjson: [String: AnyObject] = resultDic as? [String: AnyObject] { let resultStatus = Alipayjson["resultStatus"] as! String print("loginBack resultStatus=\(resultStatus)") if resultStatus == "9000" {// 请求处理成功 aliAuthBack?.finish(Alipayjson["result"] as? String) } else { aliAuthBack?.failed() } } } static func pay(signStr: String, aliPayBack: AliPayBack?) { AliPayUtils.aliPayBack = aliPayBack AlipaySDK().payOrder(signStr, fromScheme: NSLocalizedString("alipayback", comment: ""), callback: { (resp) in payBack(resultDic: resp as! [NSObject: AnyObject]) }) } static func payBack(resultDic: [NSObject: AnyObject]) { if let Alipayjson: [String: AnyObject] = resultDic as? [String: AnyObject] { let resultStatus = Alipayjson["resultStatus"] as! String print("payBack resultStatus=\(resultStatus)") if resultStatus == "9000" || resultStatus == "8000" {// 订单支付成功或正在处理中 aliPayBack?.finish(Alipayjson["result"] as? String) } else { aliPayBack?.failed() } } } } protocol AliPayBack { func finish(_ result: String?) func failed() } -
于AppDelegate添加回调(这里贴主要代码)
@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { func application(_ application: UIApplication, handleOpen url: URL) -> Bool { switch url.scheme { case NSLocalizedString("aliauthback", comment: ""): AlipaySDK().processAuth_V2Result(url) { (back) in AliPayUtils.loginBack(resultDic: back as! [NSObject: AnyObject]) } case NSLocalizedString("alipayback", comment: ""): AlipaySDK().processOrder(withPaymentResult: url) { (back) in AliPayUtils.payBack(resultDic: back as! [NSObject: AnyObject]) } default: print("handleOpenUrl1") } print("handleOpenUrl11=\(url.scheme)") return true } func application(_ application: UIApplication, open url: URL , sourceApplication: String?, annotation: Any) -> Bool { switch url.scheme { case NSLocalizedString("aliauthback", comment: ""): AlipaySDK().processAuth_V2Result(url) { (back) in AliPayUtils.loginBack(resultDic: back as! [NSObject: AnyObject]) } case NSLocalizedString("alipayback", comment: ""): AlipaySDK().processOrder(withPaymentResult: url) { (back) in AliPayUtils.payBack(resultDic: back as! [NSObject: AnyObject]) } default: print("handleOpenUrl2") } print("handleOpenUrl12=\(url.scheme)") return true } } -
登录调用(这里写部分伪代码)：
//从服务器获取签名字符串，这里后面服务器开发会贴出，客户端可以不用管。 var signStr = getSignStrFromService() AliPayUtils.login(signStr: result!, aliAuthBack: AliAuthBack()) //创建AliPayBack实例 struct AliAuthBack: AliPayBack { func finish(_ result: String?) { //登录成功，直接将获取的结果上传至服务器处理，服务器返回用户信息即可。 } func failed() { //登录失败 } }

Android端
接入前奏，注册签约的可另行百度，这里主要写代码部分
下载jar包并导入(这里使用的是alipaySdk-20180601.jar)
放入项目libs文件夹下
-
与build.gradle导入jar(这里贴部分关键代码)
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation files('libs/alipaySdk-20180601.jar') } -
于AndroidManifest.xml注册权限及activity(这里贴出部分关键代码)
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <application> <activity android:name="com.alipay.sdk.app.H5PayActivity" android:configChanges="orientation|keyboardHidden|navigation|screenSize" android:exported="false" android:screenOrientation="behind" android:windowSoftInputMode="adjustResize|stateHidden" /> <activity android:name="com.alipay.sdk.app.H5AuthActivity" android:configChanges="orientation|keyboardHidden|navigation" android:exported="false" android:screenOrientation="behind" android:windowSoftInputMode="adjustResize|stateHidden" /> </application>-
创建AliPayUtils工具文件(AuthResult/PayResult文件会后面贴出)
import android.app.Activity; import android.text.TextUtils; import android.util.Log; import com.alipay.sdk.app.AuthTask; import com.alipay.sdk.app.EnvUtils; import com.alipay.sdk.app.PayTask; import java.util.Map; public class AliPayUtils { public interface Back { public void success(String result); public void failed(); } public static void startPay(final Activity activity, final String orderInfo, final Back back) { if (orderInfo == null || back == null) { return; } new Thread(new Runnable() { @Override public void run() { // EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);//测试使用此设置 EnvUtils.setEnv(EnvUtils.EnvEnum.ONLINE);//正式环境使用此设置 PayTask alipay = new PayTask(activity); Map<String, String> result = alipay.payV2(orderInfo, true); PayResult payResult = new PayResult(result); String resultStatus = payResult.getResultStatus(); if (TextUtils.equals(resultStatus, "9000")) { back.success(payResult.getResult()); } else { back.failed(); } } }).start(); } public static void login(final Activity activity, final String authInfo, final Back back) { if (authInfo == null || back == null) { return; } new Thread(new Runnable() { @Override public void run() { AuthTask authTask = new AuthTask(activity); Map<String, String> result = authTask.authV2(authInfo, true); AuthResult authResult = new AuthResult(result, true); String resultStatus = authResult.getResultStatus(); if (TextUtils.equals(resultStatus, "9000") && TextUtils.equals(authResult.getResultCode(), "200")) { back.success(authResult.getResult()); } else { back.failed(); } } }).start(); } }
-

创建AuthResult工具文件
import android.text.TextUtils; import java.util.Map; public class AuthResult { private String resultStatus; private String result; private String memo; private String resultCode; private String authCode; private String alipayOpenId; public AuthResult(Map<String, String> rawResult, boolean removeBrackets) { if (rawResult == null) { return; } for (String key : rawResult.keySet()) { if (TextUtils.equals(key, "resultStatus")) { resultStatus = rawResult.get(key); } else if (TextUtils.equals(key, "result")) { result = rawResult.get(key); } else if (TextUtils.equals(key, "memo")) { memo = rawResult.get(key); } } String[] resultValue = result.split("&"); for (String value : resultValue) { if (value.startsWith("alipay_open_id")) { alipayOpenId = removeBrackets(getValue("alipay_open_id=", value), removeBrackets); continue; } if (value.startsWith("auth_code")) { authCode = removeBrackets(getValue("auth_code=", value), removeBrackets); continue; } if (value.startsWith("result_code")) { resultCode = removeBrackets(getValue("result_code=", value), removeBrackets); continue; } } } private String removeBrackets(String str, boolean remove) { if (remove) { if (!TextUtils.isEmpty(str)) { if (str.startsWith("\"")) { str = str.replaceFirst("\"", ""); } if (str.endsWith("\"")) { str = str.substring(0, str.length() - 1); } } } return str; } @Override public String toString() { return "resultStatus={" + resultStatus + "};memo={" + memo + "};result={" + result + "}"; } private String getValue(String header, String data) { return data.substring(header.length(), data.length()); } /** * @return the resultStatus */ public String getResultStatus() { return resultStatus; } /** * @return the memo */ public String getMemo() { return memo; } /** * @return the result */ public String getResult() { return result; } /** * @return the resultCode */ public String getResultCode() { return resultCode; } /** * @return the authCode */ public String getAuthCode() { return authCode; } /** * @return the alipayOpenId */ public String getAlipayOpenId() { return alipayOpenId; } } -
创建PayResult工具文件
import android.text.TextUtils; import java.util.Map; public class PayResult { private String resultStatus; private String result; private String memo; public PayResult(Map<String, String> rawResult) { if (rawResult == null) { return; } for (String key : rawResult.keySet()) { if (TextUtils.equals(key, "resultStatus")) { resultStatus = rawResult.get(key); } else if (TextUtils.equals(key, "result")) { result = rawResult.get(key); } else if (TextUtils.equals(key, "memo")) { memo = rawResult.get(key); } } } @Override public String toString() { return "resultStatus={" + resultStatus + "};memo={" + memo + "};result={" + result + "}"; } /** * @return the resultStatus */ public String getResultStatus() { return resultStatus; } /** * @return the memo */ public String getMemo() { return memo; } /** * @return the result */ public String getResult() { return result; } } AliPayUtils登录使用方式：
//于服务器获取登录签名字符串(这里为伪代码)，具体代码后面服务器先关会贴出。
String signStr = getSignStr();
//调用AliPayUtils登录方法
AliPayUtils.login(DemoActivity.this, signStr, new AliPayUtils.Back() {
@Override
public void success(String result) {
//登录成功，可将result上传至服务器处理。
}
@Override
public void failed() {
//登录失败
}
});
- 服务器端
- Android客户端demo中写的“真实App里，privateKey等数据严禁放在客户端，加签过程务必要放在服务端完成；”相信大家都看到了，也正是因为这句话楼主连appId都没有放客户端，但是官方并没有给出明确的解决方案。Android客户端jar包引入low到居然要下载jar文件放入，连gradle引入都不支持，无力吐槽。
- 为了解决安全问题楼主不得不将加签所有过程放服务器端，那么问题来了：
客户端的签名代码用的是客户端jar包，服务器端用的服务器jar包，且服务器根本没有签名示例代码。
-
为此楼主只有强行将客户端部分代码照搬至服务器端，不管是否规范，至少签名在服务器这边处理是做到了。代码如下(代码真心多，但是为了一个类完成所有功能，只能勉强放一起了。)：

贴完代码可能会有人代码报错，很正常，因为里边用到了官方没有说的代码（原始代码用的Android的jdk没问题，但是服务器端的部分jdk代码和客户端有差异，所以就报错了），解决方案：
# gradle用户在build.gardle加入： "org.bouncycastle:bcprov-jdk16:1.45", # mvn用户在pom.xml加入： <dependency> <groupId>org.bouncycastle</groupId> <artifactId>bcprov-jdk16</artifactId> <version>1.45</version> </dependency> 这样服务器端签名代码就写好（只是签名字符串），调用getAuthStr()方法就能返回了。
-
首先将获得的realResult上传至服务器。然后我这边贴下服务器端的处理代码（首先是getAlipayAuthCode()方法，传入的是realResult，返回的是authCode，让后将获得的authCode传入signAuthStr()方法就获得了用户信息了，具体的信息可以参考官方文档）：
private final String ALIPAY_AUTH_CODE_START = "auth_code="; private final String ALIPAY_AUTH_CODE_END = "&"; private String getAlipayAuthCode(String response) { String result = response.substring(response.indexOf(ALIPAY_AUTH_CODE_START) + ALIPAY_AUTH_CODE_START.length(), response.length() - 1); return result.substring(0, result.indexOf(ALIPAY_AUTH_CODE_END)); } public static AlipayUserInfoShareResponse signAuthStr(String authCode) throws AlipayApiException { AlipayClient alipayClient = new DefaultAlipayClient( "https://openapi.alipay.com/gateway.do", APP_ID , APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY , "RSA2"); AlipaySystemOauthTokenRequest request = new AlipaySystemOauthTokenRequest(); request.setGrantType("authorization_code"); request.setCode(authCode); AlipayUserInfoShareRequest userInfoRequest = new AlipayUserInfoShareRequest(); AlipaySystemOauthTokenResponse response = alipayClient.execute(request); if (response.isSuccess()) { AlipayUserInfoShareResponse userInfoResponse = alipayClient.execute(userInfoRequest, response.getAccessToken()); if (userInfoResponse.isSuccess()) { return userInfoResponse; } System.out.println("signAuthStr调用成功"); } else { System.out.println("signAuthStr 调用失败"); } return null; } 获得了支付宝用户信息整个登录流程也基本结束了，剩下的就是自己业务逻辑的处理了，因为整个流程实在太复杂，写的可能有很多不详细的地方，还望谅解，发现不对的地方还望及时指正，有问题也可以评论指出。
