webview转wkwebview遇到的坑
1､wkwebview里通过新窗品进行ajax的post请求时，cookie参数丢失
解决方案：不创建新wkwebview
2､原生网络请求请求后cookie无法同步到wkwebview
@implementation WKWebView (cookieMgr)
- (void)syncCookies {
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
if (@available(iOS 11.0, *)) {
WKHTTPCookieStore *cookieStroe = self.configuration.websiteDataStore.httpCookieStore;
if (cookies.count == 0) {
return;
}
for (NSHTTPCookie *cookie in cookies) {
[cookieStroe setCookie:cookie completionHandler:^{
if ([[cookies lastObject] isEqual:cookie]) {
return;
}
}];
}
}else {
for (NSHTTPCookie *ck in cookies) {
NSString *script = [NSString stringWithFormat:@"document.cookie='%@=%@;domain=%@;path=%@; expiresDate=\"%@\";isSecure=%@;sessionOnly=%@'",ck.name,ck.value,ck.domain,(ck.path?:@"/"),ck.expiresDate,(ck.isSecure ? @"TRUE":@"FALSE"),(ck.sessionOnly?@"TRUE":@"FALSE")];
[self evaluateJavaScript:script completionHandler:nil];
}
}
}
@end
3､退出登录时，再次登录，部分页面cookie错误
在退出登录时，如果将WKProcessPool单例对象重置，会造成以前打开页面和新打开cookie错误现象
4､关于原生方法调用的问题
webview采用jsexport为原生导出相应方法
wk通过js注入，创建原生对应对象并调用
JS代码示例:
window.uz$q = {
c:[],
flag:true,
};
window.uz$cb = {
fn:{},
id:1,
on:function(cbId, ret, err, del) {
if (this.fn[cbId]) {
this.fn[cbId](ret, err);
if (del) {
delete this.fn[cbId];
}
}
}
};
function _onResultCallback(cbId, ret, err, del) {
return function(){
uz$cb.on(cbId, ret, err, del);
}
}
function onResultCallback(cbId, ret, err, del) {
setTimeout(_onResultCallback(cbId, ret, err, del), 0);
};
window.uz$md = {};

newP.push(str);
}else {
newP.push(node);
}
}
}
param.param = newP;
