我们如何才能只使用特定路径的 electron.protocol.interceptFileProtocol ，而不影响其他请求? [英] How can we use electron.protocol.interceptFileProtocol with only certain paths, leaving other requests untouched?

问题描述

我想拦截某些 HTTP 请求并将它们替换为文件.所以我想我可以像这样使用 electron.protocol.interceptFileProtocol :

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?
})

我们如何允许除 http://example.com 之外的其他 http 请求继续正常工作?

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

推荐答案

在使用 protocol.interceptXXXXProtocol(scheme, handler) 时，我们正在拦截方案协议，并使用 handler 作为协议的新处理程序，发送一个新的 XXXX 请求作为响应，如 在此处的文档中所述.

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.

但是，这样做完全破坏了这个特定协议的初始处理程序，我们在处理回调执行后需要它.因此，我们只需要将它恢复到初始状态，它就可以继续正常工作:)

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 :)

让我们使用: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');
})
