Cookies and CORS restrictions don't apply here because the requests is performed by native code. 7 | 8 | You just need to change the URL: 9 | 10 | ```javascript 11 | const response = await fetch(window.WebviewProxy.convertProxyUrl(url)); 12 | console.debug(response); 13 | ``` 14 | 15 | #### To delete all Cookies use this: 16 | ```javascript 17 | window.WebviewProxy.clearCookie(); 18 | ``` 19 | 20 | # Make sure you are using a custom scheme with your iOS platform 21 | 22 | This plugin uses the WKURLSchemeHandler provided by WKWebView. It requires the latest version of cordova-ios. 23 | 24 | **You enable the custom scheme by setting these preferences in config.xml** 25 | 26 | ```xml 27 | 28 | 29 | ``` 30 | # Testing this plugin 31 | 32 | [This test app](https://github.com/NiklasMerz/cors-cookie-proxy-test-app) with custom pages and a simple backend is helpful for testing and developing this plugin. -------------------------------------------------------------------------------- /package.json: -------------------------------------------------------------------------------- 1 | { 2 | "name": "cordova-plugin-webview-proxy", 3 | "version": "0.0.5", 4 | "description": "Proxy HTTP(S) requests through native code to make CORS and Cookies work in cordova-ios", 5 | "cordova": { 6 | "id": "cordova-plugin-webview-proxy", 7 | "platforms": [ 8 | "ios" 9 | ] 10 | }, 11 | "repository": { 12 | "type": "git", 13 | "url": "https://github.com/GEDYSIntraWare/cordova-plugin-webview-proxy.git" 14 | }, 15 | "keywords": [ 16 | "ecosystem:cordova", 17 | "cordova-ios", 18 | "cordova", 19 | "webview", 20 | "wkwebview", 21 | "ios" 22 | ], 23 | "scripts": { 24 | "test": "paramedic.." 25 | }, 26 | "author": "GEDYS IntraWare GmbH", 27 | "license": "MIT", 28 | "bugs": { 29 | "url": "https://github.com/GEDYSIntraWare/cordova-plugin-webview-proxy/issues" 30 | }, 31 | "homepage": "https://github.com/GEDYSIntraWare/cordova-plugin-webview-proxy" 32 | } 33 | -------------------------------------------------------------------------------- /plugin.xml: -------------------------------------------------------------------------------- 1 | 2 | 6 | 7 | cordova-plugin-webview-proxy 8 | GEDYS IntraWare GmbH 9 | Proxy HTTP(S) requests through native code to make CORS and Cookies work in cordova-ios 10 | MIT 11 | 12 | 13 | 14 | https://github.com/GEDYSIntraWare/cordova-plugin-webview-proxy.git 15 | https://github.com/GEDYSIntraWare/cordova-plugin-webview-proxy/issues 16 | cordova,webview,wkwebview,ios 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | -------------------------------------------------------------------------------- /src/ios/WebviewProxy.m: -------------------------------------------------------------------------------- 1 | #import 2 | #import 3 | #import 4 | 5 | @interface WebviewProxy : CDVPlugin { 6 | 7 | } 8 | 9 | @property (nonatomic) NSMutableArray* stoppedTasks; 10 | 11 | - (void)clearCookie:(CDVInvokedUrlCommand*)command; 12 | 13 | @end 14 | 15 | @implementation WebviewProxy 16 | 17 | - (void) pluginInitialize { 18 | NSLog(@"Proxy active on /_https_proxy and /_http_proxy_"); 19 | self.stoppedTasks = [[NSMutableArray alloc] init]; 20 | } 21 | 22 | - (BOOL) overrideSchemeTask: (id )urlSchemeTask { 23 | NSURL * url = urlSchemeTask.request.URL; 24 | NSDictionary * header = urlSchemeTask.request.allHTTPHeaderFields; 25 | // In Versions below iOS 16 the appendString method seems to encode the string in a way that works for the request URL 26 | NSMutableString * stringToLoad = [NSMutableString string]; 27 | [stringToLoad appendString:url.path]; 28 | NSString * method = urlSchemeTask.request.HTTPMethod; 29 | NSData * body = urlSchemeTask.request.HTTPBody; 30 | 31 | // Request should be handled by this plugin if the url contains the proxy path 32 | if ([stringToLoad hasPrefix:@"/_http_proxy_"]||[stringToLoad hasPrefix:@"/_https_proxy_"]) { 33 | // First sync all cookies from the WKHTTPCookieStore to the NSHTTPCookieStorage.. 34 | // .. to make cookies from main or IAB webview available for proxy requests 35 | WKWebsiteDataStore* dataStore = [WKWebsiteDataStore defaultDataStore]; 36 | WKHTTPCookieStore* cookieStore = dataStore.httpCookieStore; 37 | [cookieStore getAllCookies:^(NSArray* cookies) { 38 | NSHTTPCookie* cookie; 39 | for(cookie in cookies) { 40 | NSMutableDictionary* cookieDict = [cookie.properties mutableCopy]; 41 | [cookieDict removeObjectForKey:NSHTTPCookieDiscard]; // Remove the discard flag.
