一、存储Cookie
1. 登录乐成后，存储Cookie到本地。由于下次重启APP，不再走登录接口的话，Cookie会丢失，所以必要先存本地。
存储时留意，要判定是当前登录体系对应的域名或IP。由于我碰到，登录接口乐成后，还出现了友盟的Cookie的，防止被其他域名或IP的Cookie给覆盖。
// 存储Cookie
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
NSURL *url = [NSURL URLWithString DCConfigSet.host];
NSString *IP = url.host;
for (NSHTTPCookie *tempCookie in cookies) {
if ([tempCookie.domain isEqualToString:IP]) {
[QDCUserDefaults setObject:tempCookie.properties forKey "KMobileServiceCookie"];
}
}
二、设置同步Cookie
方式1. iOS 11及以上的设置同步Cookie的方式：
（该方式有坑：说的是iOS11及以上就能用，但是现实使用时，我碰到 iOS14一下几率性的同步Cookie失败的问题，至今未找到缘故原由，请知道的大佬指教，感恩有你！）
取本地存储的Cookie的值，赋值到Cookie，然后针对目的域名或IP举行设置同步。
// 设置Cookie
- (void)setWebViewCookie {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
// 获取cookie信息
NSDictionary *properties = [[NSUserDefaults standardUserDefaults] objectForKey"KMobileServiceCookie"];
NSMutableDictionary *muProperties = [NSMutableDictionary dictionaryWithDictionary:properties];
NSURL *url = [NSURL URLWithStringDCConfigSet.managerHost];
NSString *IP = url.host;
[muProperties setValue:IP forKey"Domain"];
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:muProperties]; [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
// 同步cookie WKHTTPCookieStore *cookieStrore = self.webView.configuration.websiteDataStore.httpCookieStore;
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
for (NSHTTPCookie *cookie in cookies) {
if ([cookie.domain isEqualToString:IP]) {
[cookieStrore setCookie:cookie completionHandler:nil];
}
}
}
方式2. 保举使用，JS注入的方式：
// 设置webView
WKWebViewConfiguration *webConfig = [[WKWebViewConfiguration alloc] init];
// 设置偏好设置
webConfig.preferences = [[WKPreferences alloc] init];
// 默认以为YES
webConfig.preferences.javaScriptEnabled = YES;
// web内容处置惩罚池
webConfig.processPool = [[WKProcessPool alloc] init];
// 加cookie给h5辨认，表明在iOS端打开该所在
WKUserContentController *userContentController = WKUserContentController.new;
WKUserScript *cookieScript = [self injectCookieScript];
[userContentController addUserScript:cookieScript];
webConfig.userContentController = userContentController;
DWKWebView *webView = [[DWKWebView alloc] initWithFrame:self.view.bounds configuration:webConfig];
// 通过注入JS办理Cookies差别步的问题
- (WKUserScript *)injectCookieScript {
WKUserScript *userScript = [[WKUserScript alloc] initWithSource:[self cookieString] injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
return userScript;
}
// 拼接cookie字符串
- (NSString *)cookieString {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
// 获取cookie信息
NSDictionary *properties = [[NSUserDefaults standardUserDefaults] objectForKey"KMobileServiceCookie"];
NSMutableDictionary *muProperties = [NSMutableDictionary dictionaryWithDictionary:properties]; NSURL *url = [NSURL URLWithStringDCConfigSet.managerHost];
NSString *IP = url.host;
[muProperties setValue:IP forKey"Domain"];
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:muProperties]; [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
NSMutableString *script = [NSMutableString string]; [script appendString"var cookieNames = document.cookie.split('; ').map(function(cookie) { return cookie.split('=')[0] } );\n"];
for (NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) { if ([cookie.value rangeOfString"'"].location != NSNotFound) {
continue;
}
if ([cookie.domain isEqualToString:IP]) {
NSString *string = [NSString stringWithFormat"%@=%@;domain=%@;path=%@", cookie.name, cookie.value, cookie.domain, cookie.path ?: @"/"];
[script appendFormat"if (cookieNames.indexOf('%@') == -1) {document.cookie='%@'; };\n", cookie.name, string];
}
}
return script;
}
