什么是“ isForMainFrame”？请求Android WebViewClient属性中的含义？ [英] What is "isForMainFrame" request in Android WebViewClient property meaning?

问题描述

什么是 isForMainFrame 的意思是（android-21）？

是否请求了主框架。例如，对于iframe，该字段为false。

尚不清楚，因为对于下面的日志，它返回 false 用于大型机请求。

与 isMainFrame 在android-19中？

对于 google.com（根据我的区域设置，它立即重定向到 google.ru） android-19的以下日志：

我希望所有资源都能看到 true ，因为它是来自主框架（和单个框架）的资源在 google.ru。我错了吗？
解决方案
  isForMainFrame 方法实际上是从WebKit继承的。例如，这里是 Apple文档 
 
 
 
因此，这里MainFrame指的是WebKit概念，它是根WebFrame。 
 
 
在后台，WebFrame对象封装了包含在单个frame元素中的内容。 WebFrame对象的层次结构用于对整个网页进行建模，其中根称为主框架
 
 
有关详细信息，请参见文档 
 
 
 
通过此定义，只有初始请求是针对主框架的，其余是对子WebFrame的请求。
 
What is isForMainFrame meaning (android-21)?

  
whether the request was made for the main frame. Will be false for iframes, for example.
is not clear, since for the log below it returns false for main frame requests.

Is it the same as isMainFrame in android-19?

For "google.com" (which is immediately redirected to "google.ru" according to my locale) i'm getting the following log for android-19:

I expected to see true for all the resources since it's the resources from the main (and single) frame at "google.ru". Am i wrong?
解决方案
The isForMainFrame method is actually inherited from WebKit. For instance, here is in the Apple docs

Thus, here MainFrame refers to the WebKit concept, which is the root WebFrame. 

  
Behind the scenes, WebFrame objects encapsulate the content contained in a single frame element. A hierarchy of WebFrame objects is used to model an entire webpage where the root is called the main frame
You can find more on that in the docs

By this definition, only the initial request is for the "main frame", the rest are requests for the children WebFrames.
