PHP如何区分Query String与JSON格式Webhook并分别处理？

Hey there, let's sort out your webhook handling logic properly. The core goal is to distinguish between query string-based requests and JSON payloads, then run the right code for each case. Here's a polished, working version of your code with the detection logic built in:

<?php
date_default_timezone_set('America/Chicago');

// Grab raw input data
$rawQuery = $_SERVER["QUERY_STRING"];
$rawJson = file_get_contents("php://input");

// Log the full request details (including headers) to webhook.log
$date = new DateTime();
$headers = apache_request_headers();
$logEntry = sprintf("[%s]\n", $date->format('Y-m-d H:i:s'));
$logEntry .= "Request Headers:\n";
foreach ($headers as $name => $value) {
    $logEntry .= "  $name: $value\n";
}
$logEntry .= "Query String: $rawQuery\n";
$logEntry .= "Raw JSON Payload: $rawJson\n";
$logEntry .= "-------------------------\n";
file_put_contents('webhook.log', $logEntry, FILE_APPEND);

// Determine which request format we're dealing with
$isQueryStringRequest = !empty($rawQuery);
$isJsonRequest = !empty($rawJson) && json_decode($rawJson, true) !== null;

// Handle query string requests
if ($isQueryStringRequest) {
    parse_str($rawQuery, $queryData);
    // Add your query string-specific operations here
    // Example: process $queryData array
    echo "Processed query string request: " . print_r($queryData, true);
}
// Handle JSON requests
elseif ($isJsonRequest) {
    $jsonData = json_decode($rawJson, true);
    // Add your JSON-specific operations here
    // Example: process $jsonData array
    echo "Processed JSON request: " . print_r($jsonData, true);
}
// Fallback for invalid/unexpected requests
else {
    http_response_code(400);
    echo "Error: Unsupported request format";
}
?>

Key Details Explained: #

• Request Detection:
  • We check if the query string has content ($isQueryStringRequest) to catch that webhook.
  • For JSON, we verify the raw input isn't empty and that it can be parsed into valid JSON ($isJsonRequest).
• Logging: Expanded the log to include headers, query string, and raw JSON so you can debug exactly what each webhook is sending.
• Parsing:
  • parse_str() converts the query string into a usable associative array.
  • json_decode($rawJson, true) turns the JSON payload into an associative array (remove the true if you prefer an object).
• Fallback: Added a 400 Bad Request response for cases where neither format matches—this helps catch unexpected requests during testing.

If you need to adjust the priority (e.g., if a request could technically have both a query string and JSON), just reorder the conditionals. But based on your description, this should cover your two server scenarios perfectly.
