使用Guzzle 6并发调用并跟踪额外的参数

Question

所以我使用Guzzle 6进行不确定的并发api调用，但我想做的一件事是跟踪promise当前正在处理的数组值，因为我最初是根据数据库查询结果处理api调用的。之后，我想用从api中得到的任何信息将值更新回数据库。

use GuzzleHttpPool;
use GuzzleHttpClient;
use GuzzleHttpPsr7Request;
$client = new Client();
$requests = function () {
    $uri = 'http://127.0.0.1:8126/guzzle-server/perf';
    foreach($database_result as $res) {
        /*the res array contains 
        ['id' => 'db id', 'query' => 'get query array'];
        */
        $url = $uri . '?' . http_build_query($res['query']);
        yield new Request('GET', $url);
    }
};
$pool = new Pool($client, $requests(), [
    'concurrency' => 5,
    'fulfilled' => function ($response, $index) {
        /**
         * HERE i want to be able to somehow 
         * retrieve the current responses db id
         * this way I can obviously update anything 
         * i want on the db side
         */
    },
    'rejected' => function ($reason, $index) {
        /**
         * HERE i want to be able to somehow 
         * retrieve the current responses db id
         * this way I can obviously update anything 
         * i want on the db side
         */
    },
]);
// Initiate the transfers and create a promise
$promise = $pool->promise();
// Force the pool of requests to complete.
$promise->wait();
...

任何帮助都将是惊人的。我想就如何最好地处理这种情况征求意见。我更愿意以一种聪明、合乎逻辑的方式来做这件事。

感谢您的帮助

所以我想明白了。

基本上

    $requests = function () {
    $uri = 'http://127.0.0.1:8126/guzzle-server/perf';
    foreach($database_result as $key => $res) {
        /*the res array was updated to be  
        ['id' => 'get query array'];
        */
        $url = $uri . '?' . http_build_query($res);
        //here is the key difference in change
        yield $key => new Request('GET', $url);
    }
};

稍后，池功能中的索引将包含所需的索引。

希望这能有所帮助。
