需要明确的是,白名单"已经存在了一段时间,但是插件和要求是非常新的.如您所料,添加白名单"后,事实上的开放式访问功能已被弃用.或以另一种方式说,事实上的开放式访问功能已被计划并计划取消.此更改标志着取消了开放式访问功能的一步. 此外,内容安全政策(CSP)吸引了众多开发人员-因为它的宣传不力. 根据您的使用和所使用的Phonegap的版本,CSP需要进入您使用的每个HTML页面,就像您必须等待"deviceready"一样.但是,在某些情况下根本不需要它.该文档有些混乱,请仔细阅读.该文档埋在许多最新文档页面的底部. 相关链接 Phonegap构建论坛:关于在PGB上升级到cli-5.1.1的说明,现在需要白名单 科多瓦白名单指南 Phonegap白名单指南 《 Phonegap构建白名单指南》I have an application which runs well on chrome browser and on (genymotion) emulator.However, if i run it on my smartphone, each request to server (post, get, put) gives the result : Failed to load resource: net::ERR_CONNECTION_TIMED_OUTMy settings:Cordova: 5.2.0config.xml: <content src="index.html" /> <access origin="*" /> <allow-navigation href="*" /> <allow-intent href="*" />jquery:$.support.cors=true;my request: (i've done the same also with backbone, the same result)$scope.loginRequestObject = $scope.getLoginObject();$.ajax({ url : $scope.baseUrl + "/myTable", type : 'post', contentType : 'application/json; charset=utf-8', scriptCharset : "utf-8", data : JSON.stringify($scope.loginRequestObject), dataType : 'json', fail : function(a,b,c){ console.log(a); console.log(b); console.log(c); }, success: function(a,b,c){ console.log(a); console.log(b); console.log(c); });I've runned my app by both exporting and running (cordova run android) and my phone has a wireless connection. 解决方案 @Asqan,you have made a common mistake which is listed in Top Mistakes by Developers new to Cordova/Phonegap. In this instance, you need to add the white-list plugin, and CSPto your webpage.The alternative is this quick fix – but know that this fix removes all needs for white-list. This creates a security issue which you may not want to by pass.QUICK FIX Add this to your config.xml<preference name="phonegap-version" value="3.7.0" />The long answer is as such:From Top Mistakes by Developers new to Cordova/Phonegap you have hit:#6 Not setting the "phonegap version" for your compiler#7 Not setting "version" for you plugins#10 Not adding the new "white-list" and "white-list plugin" parameters in config.xml.For #6 & #7 With the CLI version, if you do not assign a version for your platform OR in ''Phonegap Build'' if you do not set the phonegap-version in config.xml, YOU WILL GET THE LATEST VERSION. If you are lucky, your program just works as expected. If you are not lucky, you'll get a set of cascading errors. Luckily for all of us, Holly Schinsky has written a nice blog post to explain it all: Cordova/PhoneGap Version Confusion http://devgirl.org/2014/11/07/cordovaphonegap-version-confusion/For #10 This relatively * NEW * requirement means – to access ANY website or resources on the web, you MUST use the whitelist and the whitelist plugin. This requirement goes into affect, if you are using cordova-android@4.0.0 or better; including cli-5.1.1. If however, your version is before 4.0.0, let's say 3.5.0 or 3.7.0, then you will not have to add the white-list requirement. To be clear, the "whitelist" has been around for a bit, but the plugin and requirement is very new. As you would expect, when the "whitelist" was added, the defacto open-access feature was deprecated. Or said another way, the defacto open-access feature was planned and scheduled to be eliminated. This change marks a step in removal of the open-access feature. In addition, the Content Security Policy (CSP) has caught numerous developers - because it was soooo poorly publicized. Depending on your use and the version of Phonegap you are using, the CSP needs to go in every single HTML page you used, just like you have to wait for 'deviceready'. However, there are cases where it is not needed at all. The documentation is confusing for some, please read it carefully. The documentation is buried in the bottom of many of the latest documentation pages.Related Links Phonegap Build Forum: Notes for upgrading to cli-5.1.1 on PGB and now required Whitelist Cordova Whitelist Guide Phonegap Whitelist Guide Phonegap Build Whitelist Guide 这篇关于net :: ERR_CONNECTION_TIMED_OUT错误来自真实设备上的cordova应用程序的请求的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
