那个网站可以做微课,alexa排名什么意思,南京华璋建设网站,dede网站地图栏目如何上传文件我本来是想直接讲Android支付这一块的#xff0c;包括支付宝#xff0c;微信#xff0c;其他第三方整合支付等#xff0c;但是微信开放平台他对我的账号做了限制#xff0c;所有我今天就先把重心放在支付宝的支付上#xff0c;也算是写得尽可能详细些吧#xff0c;毕竟是…我本来是想直接讲Android支付这一块的包括支付宝微信其他第三方整合支付等但是微信开放平台他对我的账号做了限制所有我今天就先把重心放在支付宝的支付上也算是写得尽可能详细些吧毕竟是第三方的SDK只要我们耐心的阅读文档和开发引导这个其实不是很难的我也是没有用过支付宝的支付但是我相信你看完这篇博客也会对他了如指掌的好的我们正文开始一.准备步骤1.登录官网他的官网就是蚂蚁金服的开放平台了我们可以访问 蚂蚁金服开放平台 并且注册账号进行登录创建应用如果你是现有的应用直接接入支付功能的话可以不看这里我这里是因为需要讲博客所有重新创建了一个项目并且在Android Studio里也重新创建了一个项目Android Studio里创建的项目我把他叫做SimpleMall简单商城的意思那在开放平台我们又是如何去创建应用呢点击-进入我的开放平台-应用就可以看到应用管理了。我们点击创建应用创建成果之后有很多的选项包括需要你上传这些先不管我们这个时候可以看到已经拿到了APPID: 2017062807585767这样我们就可以继续下一步的准备了3.签约大部分的功能需要签约才能使用很遗憾我这个个体户就不行了4.配置密钥配置秘钥是支付这一环节很重要的因素也是分了两个步骤生成秘钥和配置秘钥这里使用的RAS非对称加密我们按照文档上来首先是下载工具了这里有win和mac两个地址我是win下载下来是这个样子的我们按照图中的配置拿到了公钥和私钥那我们可以配置了我们找到项目详情然后这里是两种方式我们选择的是RSA方式么其实哪种方式都是可以的到这里这个也配置好了5.SDK 下载到这里我们就可以直接去下载他的SDK了SDK下载地址这个压缩包下载下来什么都有要找到Android的部分二.SDK集成我们现在就开始来把jar集成进去支付宝给我们提供的就是一个jar我们放进我们的工程里面去并且在我们的app/build.gradle里配置一下compile files(libs/alipaySdk-20170623-proguard.jar)这样Jar就集成好了然后配置一下清单文件android:namecom.alipay.sdk.app.H5PayActivityandroid:configChangesorientation|keyboardHidden|navigationandroid:exportedfalseandroid:screenOrientationbehind/android:namecom.alipay.sdk.auth.AuthActivityandroid:configChangesorientation|keyboardHidden|navigationandroid:exportedfalseandroid:screenOrientationbehind/并且添加权限如大于等于Android6.0还需要动态申请下权限如果你的项目需要混淆需要添加混淆规则-libraryjars libs/alipaySDK-20150602.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 *;}嗯可以说得上是比较简单的我们继续三.支付接口调用其实支付宝的调用还是比较简单的我们来看一下我的调用方式public class MainActivity extends AppCompatActivity implements View.OnClickListener {private Button btnPay;private static final int SDK_PAY_FLAG

Permissions,sub_code:isv.insufficient-isv-permissions,sub_msg:ISV权限不足}}这是因为我们这个应用并没有去签约功能所有并没有这个权限好的但是起码可以看出我们已经可以调用支持包的支付了那我们继续来了解他的功能吧四.Api首先我们看下他提供的OrderInfoUtil2_0这个工具类public class
