本文介绍了我们如何仅在某些路径下使用electron.protocol.interceptFileProtocol,而使其他请求保持不变?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想拦截某些HTTP请求并将其替换为文件。所以我想我可以像这样使用 electron.protocol.interceptFileProtocol

  protocol.interceptFileProtocol('http',(request,callback)=> {
//仅拦截对 http://example.com的请求,如果$( request.url.startsWith( http://example.com)){
callback( / path / to / file)
}

//否则,让HTTP请求的行为像平常一样。
//但是如何?
})

如何允许除 http://example.com 以外的其他 http 请求继续正常运行?

解决方案

在使用 protocol.interceptXXXXProtocol(scheme,handler)时,我们是拦截方案协议,并使用处理程序作为协议的新处理程序,该处理程序发送新的XXXX请求作为响应,如

但是,这样做完全破坏了该特定协议的初始处理程序,在处理回调执行之后我们将需要它。因此,我们只需要将其还原到其初始状态,即可使其继续正常工作:)



让我们使用: protocol。 uninterceptProptocol(scheme)

  protocol.interceptFileProtocol('http',(request,callback)=> ; {
//如果(request.url.startsWith( http://example.com)){
回调,仅拦截对 http://example.com的请求( / path / to / file)
}

//否则,请使HTTP请求的行为像普通的一样。
protocol.uninterceptProtocol('http');
})


I'd like to intercept certain HTTP requests and replace them with files. So I thought I could use electron.protocol.interceptFileProtocol like so:

protocol.interceptFileProtocol('http', (request, callback) => {
  // intercept only requests to "http://example.com"
  if (request.url.startsWith("http://example.com")) {
    callback("/path/to/file")
  }

  // otherwise, let the HTTP request behave like normal.
  // But how?
})

How do we allow other http requests other than http://example.com to continue working as normal?

解决方案

When using protocol.interceptXXXXProtocol(scheme, handler), we are intercepting scheme protocol and uses handler as the protocol’s new handler which sends a new XXXX request as a response, as said in the doc here.

However, doing so totally breaks the initial handler for this specific protocol, which we would need after handling the callback execution. Thus, we just need to restore it back to its initial state, so that it can continue working as normal :)

Let's use: protocol.uninterceptProptocol(scheme)

protocol.interceptFileProtocol('http', (request, callback) => {
  // intercept only requests to "http://example.com"
  if (request.url.startsWith("http://example.com")) {
    callback("/path/to/file")
  }

  // otherwise, let the HTTP request behave like normal.
  protocol.uninterceptProtocol('http');
})
