<p>最近公司项目做到支付模块,之前也做过,没整理成博客,这次整理一下。</p> <h2><strong>微信支付</strong></h2> <h3><strong>前期准备</strong></h3> <ol> <li>注册账号,创建应用,开通微信支付。</li> <li>查看APP支付文档: <a href="/misc/goto?guid=4959727101509037925" rel="nofollow,noindex">https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=8_1</a></li> <li>了解支付流程: <p style="text-align:center"><img src="https://simg.open-open.com/show/ad01b32cdd653bd8e49754904d54df7c.jpg"></p> </li> </ol> <h3><strong>接入SDK</strong></h3> <ol> <li>引入libs,下载 <a href="/misc/goto?guid=4959727101593585161" rel="nofollow,noindex">https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=11_1</a> ,并将libammsdk.jar放到libs文件夹下。</li> <li>配置签名<br> 在debug下直接配置key,这样就可以在debug下调试了。 <pre> <code class="language-java">signingConfigs { debug { storeFile file("你的keystore文件路径") storePassword "xxx" keyAlias "xxx" keyPassword "xxx" } release { storeFile file("你的keystore文件路径") storePassword "xxx" keyAlias "xxx" keyPassword "xxx" } } buildTypes { debug { signingConfig signingConfigs.debug } release { signingConfig signingConfigs.release } }</code></pre> </li> <li>创建WXPayEntryActivity<br> 在报名下创建如下图的Activity,demo里也有,WXPaEntryActivity是支付的回调,WXEntryActivity是微信登录和分享的回调。 <p style="text-align:center"><img src="https://simg.open-open.com/show/51dbf8b7716c7715aa1937a0d11be945.jpg"></p> </li> <li>AndroidManifest.xml中注册 <pre> <code class="language-java"><activity android:name=".wxapi.WXPayEntryActivity" android:exported="true" android:launchMode="singleTop" android:screenOrientation="portrait" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:windowSoftInputMode="stateHidden"/></code></pre> </li> <li>加入混淆 <pre> <code class="language-java">-libraryjars libs/libammsdk.jar -keep class com.tencent.** { *;}</code></pre> </li> </ol> <h3><strong>接口调用</strong></h3> <pre> <code class="language-java">/** * 调用微信支付 * @param datas 微信支付数据 */ private void toWXPay(String datas) { IWXAPI api = WXAPIFactory.createWXAPI(PayActivity.this, WX_APP_ID); api.registerApp(WX_APP_ID); try { JSONObject jsonObject = new JSONObject(datas); PayReq req = new PayReq(); req.appId = jsonObject.getString("appid");// 微信开放平台appid req.nonceStr = jsonObject.getString("noncestr");// 随机字符串 req.packageValue = jsonObject.getString("package");// 支付内容 req.partnerId = jsonObject.getString("partnerid");// 财付通id req.prepayId = jsonObject.getString("prepayid");// 微信预支付编号 req.sign = jsonObject.getString("sign");// 签名 req.timeStamp = jsonObject.getString("timestamp");// 时间戳 req.extData = "app data"; // optional // 在支付之前,如果应用没有注册到微信,应该先调用IWXMsg.registerApp将应用注册到微信 api.sendReq(req); } catch (JSONException e) { e.printStackTrace(); } }</code></pre> <h3><strong>支付回调</strong></h3> <pre> <code class="language-java">public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler { private IWXAPI api; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); api = WXAPIFactory.createWXAPI(this, Config.WX_APP_ID); api.handleIntent(getIntent(), this); } @Override protected void onNewIntent(Intent intent) { super.onNewIntent(intent);

break; } finish(); } } }</code></pre> <h3><strong>遇到的问题</strong></h3> <ol> <li> <p>未安装微信客户端的情况下使用,然后会发现提示 E/ActivityThread: Failed to find provider info for com.tencent.mm.sdk.plugin.provider ,因为微信没有html5页面能使用支付,所以我们必须要在使用支付之前做个判断,因为微信sdk有提供个参数可以判断,所以应该加上:</p> <pre> <code class="language-java">private boolean isWXAppInstall() { IWXAPI api = WXAPIFactory.createWXAPI(PayActivity.this, WX_APP_ID); api.registerApp(WX_APP_ID); boolean isWXAppInstalled = api.isWXAppInstalled() && api.isWXAppSupportAPI(); return isWXAppInstalled; } if (isWXAppInstall()) { DialogUtil.showProDialog(PayActivity.this); toWXPay(datas); } else { Toast.makeText(this, "未安装微信客户端", Toast.LENGTH_SHORT).show(); }</code></pre> </li> <li> <p>Android7.0上会出现回调成功重复多次,这个待再次确认,可能是微信的bug。</p> </li> </ol> <h2><strong>支付宝支付</strong></h2> <h3><strong>前期准备</strong></h3> <ol> <li>注册账号,创建应用,开通支付功能。</li> <li>查看文档: <a href="https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7386797.0.0.Eky59h&treeId=59&articleId=103563&docType=1" rel="nofollow,noindex">支付文档</a></li> <li>了解支付流程: <p style="text-align:center"><img src="https://simg.open-open.com/show/ae5e709ef9135edddbb31056db4117f2.jpg"></p> </li> </ol> <h3><strong>接入SDK</strong></h3> <ol> <li>引入libs,下载 <a href="https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7629140.0.0.Q5gnm8&treeId=193&articleId=104509&docType=1" rel="nofollow,noindex">支付宝SDK及DEMO</a> ,并将alipaySdk-xx.jar包放到libs文件夹下</li> <li>AndroidManifest.xml中注册 <pre> <code class="language-java"><activity android:name="com.alipay.sdk.app.H5PayActivity" android:configChanges="orientation|keyboardHidden|navigation" android:exported="false" android:screenOrientation="behind"/> <activity android:name="com.alipay.sdk.auth.AuthActivity" android:configChanges="orientation|keyboardHidden|navigation" android:exported="false" android:screenOrientation="behind"/></code></pre> </li> <li>加入权限 <pre> <code class="language-java"><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" /></code></pre> </li> <li>加入混淆 <pre> <code class="language-java">-libraryjars libs/alipaySdk-xx.jar -keep class com.alipay.android.app.IAlixPay{*;} -keep class com.alipay.android.app.IAlixPay$Stub{*;} -keep class com.alipay.android.app.IRemoteServiceCallback{*;} -keep class com.alipay.android.app.IRemoteServiceCallback$Stub{*;} -keep class com.alipay.sdk.app.PayTask{ public *;} -keep class com.alipay.sdk.app.AuthTask{ public *;}</code></pre> <h3><strong>接口调用</strong></h3> 支付宝的demo已经写得很明了易懂了,这里简单列出接口调用的主要代码,其他代码请看支付宝DEMO。 <pre> <code class="language-java">/** * 调取支付宝SDK * * @param payInfo 支付信息 */ private void alipay(final String payInfo) { Runnable payRunnable = () -> { PayTask alipay = new PayTask(PayActivity.this);

} else { if (TextUtils.equals(resultStatus, "8000")) { Toast.makeText(PayActivity.this, "支付结果确认中", Toast.LENGTH_SHORT).show(); } else { // 其他值就可以判断为支付失败,包括用户主动取消支付,或者系统返回的错误 Toast.makeText(PayActivity.this, "支付失败", Toast.LENGTH_SHORT).show(); } } break; } default: break; } } };</code></pre> <h3><strong>遇到的问题</strong></h3> </li> <li>很容易遇到的问题就是支付参数遗漏,可以直接 查看文档</li> <li>还会可能遇到支付错误,可以直接 查看文档</li> </ol> <p> </p> <p>来自:http://www.jianshu.com/p/fcd1c36f6230</p> <p> </p>
