接入支付宝支付SDK
接入支付宝支付SDK
可以说支付宝支付接入是所有SDK最好接入的，没有之一。
客户端不用签名，也不用管包名，也不用管签名文件，就接口返回订单，把订单交给支付宝SDK调用就行，成功或者失败都在当前界面返回给你。你再去通知接口。

按照文档说明接入SDK和相关配置，在这就不重复了
客户端支付关键代码===》支付接口的调用(调起支付弹框)
记住支付接口的调用必须在独立的非ui线程中执行，即需新开线程里面调用。可以想官方demo一样用new Thread方式。
下面我给出用Observable方式示例代码
在PayUtils中
/**
* desc:支付宝支付
* Created by congge on 2018/8/27 17:20
* @param orderInfo 接口返回的订单
**/
public static void aliPay(final Activity activity, final String orderInfo, final OrderListener orderListener) {
Observable.just(orderInfo)
.map(new Function () {
@Override
public String apply(String orderInfo) throws Exception {
//用户在商户app内部点击付款，是否需要一个loading做为在钱包唤起之前的过渡，这个值设置为true
return new PayTask(activity).pay(orderInfo, true);
}
})
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Consumer () {
@Override
public void accept(String payResult) throws Exception {
orderListener.onPayResult(payResult);
}
});
}
支付结果返回处理
返回例子：
resultStatus={9000};memo={};result={{"alipay_trade_app_pay_response":{"code":"10000","msg":"Success","app_id":"2016091300503896","auth_app_id":"2016091300503896","charset":"utf-8","timestamp":"2018-08-28 17:51:11","out_trade_no":"nVElbd74TW6WnEyxQwvX8A","total_amount":"0.01","trade_no":"2018082821001004680500208879","seller_id":"2088102175487650"},"sign":"W0Hg9k4GxL8Oaxymvqk2i65WNDQxYp6HGve32ek6VjSRnymmI3GQTjpQVbZuDzvjcwQ/HIkM97PoBGAVlTmi/wiJcqDgSSDzDY7AFnNN0OcK0ehWGwKQINA4IDGh51A7yY/vYKmR0VW+2OwGhlRPPMMZtQOEqh8a9/aIijzT6ZLwy9Hl4ayG/fVKhdC1VdckF6+C25BFNp3fIxarg5tfEunm7N9iWngKCUsnP+IZz05OHdvynimgYPcBnbBERHG97GVqRT/EdBWTQyIDMc0LemScAYxJixTVgXDkRddQjzWZ7HgLdBfjs0nXY24puHudT76ERxVY+8NkoKle/QI+FA==","sign_type":"RSA2"}}
也可以自己打log看看
处理示例代码：
//支付宝支付
PayUtils.aliPay(this, result.getSignDataStr(), new PayUtils.OrderListener() {
@Override
public void onPayResult(String payResult) {
PayResult pr = new PayResult(payResult);
String rs = pr.getResultStatus();
String r = pr.getResult();
switch (rs) {
case AliPayResultStatus.PAY_SUCCESS:
ToastUtils.show(R.string.pay_success);
//通知接口支付成功
break;
case AliPayResultStatus.PAY_PROCESSING:
case AliPayResultStatus.PAY_UNKNOWN:
ToastUtils.show(R.string.pay_fail);
//支付可能成功，要接口去查询
break;
default:
ToastUtils.show(R.string.pay_fail);
//通知接口支付失败，取消订单
}
}
});
上面方法中：
//通知接口支付成功 //支付可能成功，要接口去查询 //通知接口支付失败，取消订单。根据你产品需求要不要通知你服务器做的操作。正常是要的，用来改变订单状态
PayResult.class
public class PayResult {
private String resultStatus;
private String result;
private String memo;
public PayResult(String rawResult) {
if (TextUtils.isEmpty(rawResult))
return;
String[] resultParams = rawResult.split(";");
for (String resultParam : resultParams) {
if (resultParam.startsWith("resultStatus")) {
resultStatus = gatValue(resultParam, "resultStatus");
}
if (resultParam.startsWith("result")) {
result = gatValue(resultParam, "result");
}
if (resultParam.startsWith("memo")) {
memo = gatValue(resultParam, "memo");
}
}
}
@Override
public String toString() {
return "resultStatus={" + resultStatus + "};memo={" + memo
+ "};result={" + result + "}";
}
private String gatValue(String content, String key) {
String prefix = key + "={";
return content.substring(content.indexOf(prefix) + prefix.length(),
content.lastIndexOf("}"));
}
public String outOrder() {
String order = ""out_trade_no"";
if (result.contains(order)) {
String begin = result.substring(result.indexOf(order));
String ss = begin.split(",")[0];
String newS = ss.replace(""", "")
.replace("}", "")
.replace(":", "")
.replace("out_trade_no", "");
try {
return newS;
} catch (Exception e) {
e.printStackTrace();
}
}
return "";
}
/**
* @return the resultStatus
*/
public String getResultStatus() {
return resultStatus;
}
/**
* @return the memo
*/
public String getMemo() {
return memo;
}
/**
* @return the result
*/
public String getResult() {
return result;
}}
最后给下支付返回码表
AliPayResultStatus.class
public class AliPayResultStatus {
/**
* 订单支付成功,唯一肯定是支付成功的
*/
public static final String PAY_SUCCESS = "9000";
/**
* 正在处理中，支付结果未知（有可能已经支付成功），请查询商户订单列表中订单的支付状态
*/
public static final String PAY_PROCESSING = "8000";
/**
* 订单支付失败
*/
public static final String PAY_FAIL = "4000";
/**
* 重复请求
*/
public static final String PAY_REPEAT = "5000";
/**
* 用户中途取消
*/
public static final String PAY_PROCESS_CANCEL = "6001";
/**
* 网络连接出错
*/
public static final String PAY_NET_ERROR = "6002";
/**
* 支付结果未知（有可能已经支付成功），请查询商户订单列表中订单的支付状态
*/
public static final String PAY_UNKNOWN = "6004";}
还有一个直接弃用沙箱调试模式，否则提示支付失败也有可能不知道错在那，怕金额大，和接口商量，测试服务器就用0.01测试。

Q1: 请问在VB.net 中能不能实现这种功能
基本思路：
1，设置绘图区域的坐标。
2，将每个站点的坐标（x,y)保存到数组。
3，通过鼠标单击点的坐标（x,y)与数组比较，然后确定显示相应信息。

Q4: VB.NET中怎么加载第三方控件
点击菜单：项目=》添加引用 弹出窗口后选择“COM”项，然后找到你要加载的控件。
记得先调用CMD使用 regsvr32 注册你准备加载的控件哈。
