如何用AutoHotkey程序化获取谷歌搜索结果首条URL及视频链接解析

Great start with fetching the Google Video search page HTML! To pull the first video URL, we need to parse the HTML to target Google's redirect link (they wrap actual video URLs in their /url endpoint), then decode the encoded URL to get the real address. Here's how to extend your code:

Step 1: Update Your Existing Code #

Add the parsing logic right after retrieving the HTML content:

Send ^c
; Use URL encoding for the clipboard content to handle special characters safely
if !Html := UrlGet("https://www.google.com/search?tbm=vid&hl=en-TR&source=hp&biw=&bih=&q=" . EncodeURIComponent(Clipboard)) {
    MsgBox No data returned from Google.com
    return
}

; Match the first Google redirect link pattern
if !RegExMatch(Html, "i)/url\?q=([^&]+)", match) {
    MsgBox No video result found for your query
    return
}

; Decode the URL-encoded video link to get the actual address
firstVideoUrl := UrlDecode(match1)

; Example action: Open the video in your default browser
Run, %firstVideoUrl%
MsgBox First video URL: %firstVideoUrl%

Step 2: Add Required Helper Functions #

AutoHotkey v1 doesn’t include built-in URL encoding/decoding, so include these functions to handle special characters:

; URL-encode text to safely pass query parameters
EncodeURIComponent(str) {
    VarSetCapacity(encoded, StrLen(str)*3, 0)
    if DllCall("Urlmon\UrlEscape", "Str", str, "Str", encoded, "UInt", StrLen(str)*3, "UInt", 0)
        return encoded
    return str
}

; URL-decode text to retrieve the actual video URL
UrlDecode(str) {
    str := StrReplace(str, "+", " ")
    VarSetCapacity(decoded, StrLen(str)*2, 0)
    if DllCall("Urlmon\UrlUnescape", "Str", str, "Str", decoded, "UInt", StrLen(str)*2, "UInt", 0)
        return decoded
    return str
}

Key Details to Keep in Mind: #

• Regex Breakdown: The pattern /url\?q=([^&]+) targets the first Google redirect link, capturing everything after q= until the first & (which signals the start of extra Google parameters).
• URL Safety: Using EncodeURIComponent on the clipboard content ensures spaces, ampersands, and other special characters don’t break the search URL.
• Google’s Dynamic HTML: Google often updates its search page structure. If this regex stops working, inspect the page source to find the new pattern for video links (look for anchor tags pointing to video content).
