本来以为web端的微信支付，跟原生android 关系不大，我们只需要webview加载链接就好，谁知道就这样了

头大，看了下微信文档

原因是没有加"Referer"
所以要这样修改：
protected WebViewClient mWebViewClient = new WebViewClient() {
private HashMap<String, Long> timer = new HashMap<>();
@Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
super.onReceivedError(view, request, error);
}
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
return shouldOverrideUrlLoading(view, request.getUrl() + "");
}
@Nullable
@Override
public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
return super.shouldInterceptRequest(view, request);
}
//
@Override
public boolean shouldOverrideUrlLoading(final WebView view, String url) {
LogUtils.iTag(TAG, "view:" + new Gson().toJson(view.getHitTestResult()));
LogUtils.iTag(TAG, "mWebViewClient shouldOverrideUrlLoading:" + url);
//intent:// scheme的处理 如果返回false ， 则交给 DefaultWebClient 处理 ， 默认会打开该Activity ， 如果Activity不存在则跳到应用市场上去. true 表示拦截
//例如优酷视频播放 ，intent://play?...package=com.youku.phone;end;
//优酷想唤起自己应用播放该视频 ， 下面拦截地址返回 true 则会在应用内 H5 播放 ，禁止优酷唤起播放该视频， 如果返回 false ， DefaultWebClient 会根据intent 协议处理 该地址 ， 首先匹配该应用存不存在 ，如果存在 ， 唤起该应用播放 ， 如果不存在 ， 则跳到应用市场下载该应用 .
if (url.startsWith("intent://") && url.contains("com.youku.phone")) {
return true;
}
/*//微信H5支付核心代码，此方法亦可以唤起支付
if (url.startsWith("weixin://wap/pay?")) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
} else {
Map<String, String> extraHeaders = new HashMap<>();
extraHeaders.put("Referer", "https://wl.isct.cn");
view.loadUrl(url, extraHeaders);
}
return true;*/
try {
if (url.contains("wx.tenpay.com")) {
isWxPay = true;
Map weixinHearder = new HashMap();
weixinHearder.put("Referer", "此处是申请的授权域名，注意是全拼");
WebView webView = new WebView(getContext());
layoutWebView.addView(webView);
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setCacheMode(WebSettings.LOAD_NO_CACHE);
webView.loadUrl(url, weixinHearder);
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("weixin://")) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
return true;
}
});
}
} catch (Exception e) {
e.printStackTrace();
Xtoastutils.info("调用微信支付失败！");
}
return true;
}
//处理https请求
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, android.net.http.SslError error) {
handler.proceed();
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
LogUtils.iTag(TAG, "mUrl:" + url + " onPageStarted target:" + getUrl());
timer.put(url, System.currentTimeMillis());
if (url.equals(getUrl())) {
pageNavigator(View.GONE);
} else {
pageNavigator(View.VISIBLE);
}
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
if (timer.get(url) != null) {
long overTime = System.currentTimeMillis();
Long startTime = timer.get(url);
LogUtils.iTag(TAG, " page mUrl:" + url + " used time:" + (overTime - startTime));
LogUtils.eTag("ffffffffffasdasd", " page mUrl:\" + url + \" used time:\" + (overTime - startTime)----" + count);
}
}
@Override
public void onReceivedHttpError(WebView view, WebResourceRequest
request, WebResourceResponse errorResponse) {
super.onReceivedHttpError(view, request, errorResponse);
if (request.isForMainFrame()) {
if (count >= 3) {
count = 0;
shuaxin.setVisibility(View.VISIBLE);
} else {
shuaxin.setVisibility(View.GONE);
}
}
}
@Override
public void onReceivedError(WebView webviews, int errorCode, String description, String
failingUrl) {
super.onReceivedError(webview, errorCode, description, failingUrl);
LogUtils.iTag(TAG, "onReceivedError:" + errorCode + " description:" + description + " errorResponse:" + failingUrl);
failingUrls = failingUrl;
count++;
if (count < 3) {
shuaxin.setVisibility(View.GONE);
webviews.loadUrl(failingUrl);
}
shuaxin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
LogUtils.eTag("asfaseaf", webview + "----" + failingUrls);
mAgentWeb.getUrlLoader().reload();
}
});
}
};
为了防止在支付完成后重复唤起的现象，还需要在onresume里增加：
@Override
public void onResume() {
mAgentWeb.getWebLifeCycle().onResume();//恢复
if (isWxPay) {
mAgentWeb.getWebCreator().getWebView().reload();
}
super.onResume();
}
如此，便可以在webview里成功唤起微信进行支付，至于支付完成的回调，可以查看
一、回调页面
正常流程用户支付完成后会返回至发起支付的页面，如需返回至指定页面，则可以在MWEB_URL后拼接上redirect_url参数，来指定回调页面。
如，您希望用户支付完成后跳转至https://www.wechatpay.com.cn，则可以做如下处理：
假设您通过统一下单接口获到的MWEB_URL= https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?prepay_id=wx20161110163838f231619da20804912345&package=1037687096
则拼接后的地址为MWEB_URL= https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?prepay_id=wx20161110163838f231619da20804912345&package=1037687096&redirect_url=https%3A%2F%2Fwww.wechatpay.com.cn
