RN里接入微信的H5支付ios和android的一些配置(主要是在webview中手動設(shè)置referer)
anroid 的配置
修改RNCWebViewManager.java 文件 路徑/node_modules/react-native-webview/android/src/main/java/com/reactnativecommunity/RNCWebViewManager.java?
1. 定義refererUrl??
添加 public static String refererUrl = null;
2.添加Referer
刪除
root.loadUrl(args.getString(0));
添加
HashMapheaderMap=newHashMap<>();
if(refererUrl!=null) {
headerMap.put("Referer", refererUrl);
? ? ? ? }
root.loadUrl(args.getString(0), headerMap);
3設(shè)置我們的referer
refererUrl = activeUrl;

1.info.plist配置scheme
需要將微信H5支付的安全域名配置成scheme,不設(shè)置會報商家參數(shù)格式不對
2.設(shè)置我們的referer
