ios - Cordova:Ajax 调用在 iOS 上不起作用，在 Android 上运行良好

Question

我是第一次使用 Cordova(不是 Phonegap!)，我的应用程序在 Android 上运行良好，但无法访问外部服务器以在 iOS 上进行 ajax 调用。我加了

<access origin="*" />

到 config.xml 没有任何成功。我能找到的所有解决方案都只能在 Phonegap 中使用。有谁知道如何解决这个问题？甚至可能是 Xcode 中的设置？非常感谢!

Answer 1

在过去的两 (2) 周内，Cordova 进行了一些重大更改。文档还没有跟上。我不认为它会 catch 至少几周。您有两 (2) 个选项:

1. 将您的编译器版本设置为 Cordova 4.0.0 之前的版本
2. 遵循使用白名单的完整协议(protocol)

我推荐#2。

来自 Top Mistakes by Developers new to Cordova/Phonegap你打了:

• #6 没有为您的编译器设置“phonegap 版本”
• #7 没有为你的插件设置“版本”
• #10 不在 config.xml 中添加新的“白名单”和“白名单插件”参数。

对于#6 和#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:

对于#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 and cli-5.2.0. 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.
