二、微信支付
1. 微信支付流程图
相比较而言，微信支付是要比支付宝麻烦一些，并且微信的开发文档个人也感觉写的比较乱，初次接触会有些懵。
2. 集成前准备
3.开始集成
微信支付可以直接在app build.gradle中设置
/*微信支付集成*/
compile 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'
然后在你的包下，这里要注意以下放在指定包下边
AndroidManifest.xml配置
<!--微信支付，回掉-->
<activity
android:name=".wxapi.WXPayEntryActivity"
android:exported="true"
android:launchMode="singleTop" />
微信的后台参数返回，相对于支付宝的返回信息，微信返回信息更加清晰一下，不过没啥用，一会加密完都一个样子
格式化后：
{
"msg":"success",
"code":200,
"data":{
"appid":"自己申请的appId",
"noncestr":"jqEmamoTbMoi0hRP",
"package":"Sign=WXPay",
"partnerid":"150****351",
"prepayid":"wx21144021******fd37e2948041031",
"sign":"50E345DCF6900A*****10126E7424",
"timestamp":"1529563221"
},
"status":"0"
}
拿到返回参数，微信支付方法
/*微信支付测试OK*/
private void testWxPay(final String key, final String value) {
StringRequest stringRequest = new StringRequest(Request.Method.POST, NetWorkUrl.WXPAY, 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 jsonObject = JSONObject.parseObject(s.toString()).getString("data");
String appId = JSONObject.parseObject(jsonObject).getString("appid");
String sign = JSONObject.parseObject(jsonObject).getString("sign");
String packageWx = JSONObject.parseObject(jsonObject).getString("package");
String partnerid = JSONObject.parseObject(jsonObject).getString("partnerid");
String prepayid = JSONObject.parseObject(jsonObject).getString("prepayid");
String noncestr = JSONObject.parseObject(jsonObject).getString("noncestr");
String timestamp = JSONObject.parseObject(jsonObject).getString("timestamp");
Log.e("GoPayOrderActivity", "onResponse: appId" + appId);
Log.e("GoPayOrderActivity", "onResponse: sign" + sign);
Log.e("GoPayOrderActivity", "onResponse: package" + packageWx);
Log.e("GoPayOrderActivity", "onResponse: partnerid" + partnerid);
Log.e("GoPayOrderActivity", "onResponse: prepayid" + prepayid);
Log.e("GoPayOrderActivity", "onResponse: noncestr" + noncestr);
Log.e("GoPayOrderActivity", "onResponse: timestamp" + timestamp);
api = WXAPIFactory.createWXAPI(GoPayOrderActivity.this, appId); PayReq req = new PayReq();
//req.appId = "wxf8b4f85f3a794e77"; // 测试用appId
//req的参数接受可以拿取order对象的数据
req.appId = appId;
req.partnerId = partnerid;
req.prepayId = prepayid;
req.nonceStr = noncestr;
req.timeStamp = timestamp;
req.packageValue = packageWx;
req.sign = sign;
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);
}
}
}, 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("productId", "1");
// map.put("productId", "1");
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*/
}
微信支付回调
WXPayEntryActivity.java
public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {
private static final String TAG = "WXPayEntryActivity";
private IWXAPI api;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pay_result);
api = WXAPIFactory.createWXAPI(this, Constants.APP_ID);
api.handleIntent(getIntent(), this);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}
@Override
public void onReq(BaseReq req) {
}
@Override
public void onResp(BaseResp resp) {
Log.d(TAG, "onPayFinish, errCode = " + resp.errCode);
if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
AlertDialog.Builder builder = new AlertDialog.Builder(WXPayEntryActivity.this);
/*注释掉的可以成功*/
builder.setTitle(R.string.app_tip);
builder.setMessage(getString(R.string.pay_result_callback_msg, String.valueOf(resp.errCode)));
builder.show();
int code = resp.errCode;
switch (code) {
case 0:
MobclickAgent.onEvent(WXPayEntryActivity.this, "payment_success", "付款成功");
// finish();
// Toast.makeText(this, "支付成功", Toast.LENGTH_SHORT).show();
/*跳转我的会员页面*/
AppApplication.addActivity(WXPayEntryActivity.this);
Intent intent = new Intent(this, MyVipActivity.class);
startActivity(intent);
break;
case -1:
MobclickAgent.onEvent(WXPayEntryActivity.this, "payment_fali", "付款失败");
// 失败原因 可能的原因：签名错误、未注册APPID、项目设置APPID不正确、注册的APPID与设置的不匹配，其他异常等
Toast.makeText(this, "支付失败", Toast.LENGTH_SHORT).show();
finish();
break;
case -2:
Toast.makeText(this, "支付取消", Toast.LENGTH_SHORT).show();
finish();
break;
default:
Toast.makeText(this, "支付取消", Toast.LENGTH_SHORT).show();
finish();
break;
}
}
}
}
完成上述，微信支付也是可以完成的了，注意测试的时候要用Release包，测试包是调用不起来微信的
