Question

我正在使用加拿大渔业和海洋局SOAP Web服务（https://tides.gc.ca/eng/info/WebServicesWLD和https://ws-shc.qc.dfo-mpo.gc.ca/predictions?wsdl）设置潮汐观测端点。它涉及到查看使用原始PHP的旧应用程序，并将其移植到Laravel中。 vanilla和Laravel版本都可以使用，但是由于某种原因，在Laravel中，如果没有请求超时，我不能将结果的最大大小设置为50-100以上，但是在旧应用程序中，它设置为1000。本地，结果有所不同，唯一的区别似乎是使用Laravel。

我在PHP操场上举了一些例子。示例1和示例2在PHP操场上的最大大小为1000，并且响应时间相等，这似乎表明Laravel可能是问题所在。

示例1-旧的应用程序代码： https://www.tehplayground.com/XYXERmL9kHmdTvLD

示例2-新的应用程序代码，但已精简为原始PHP，以确保不是我自己的代码成为问题 https://www.tehplayground.com/N2T3PTQSBfaWSQPh

Laravel中的实现，在不超时的情况下最大大小不能超过50-100，而且我不知道为什么或如何解决它。

示例3-Laravel代码：

我包括了我正在使用的完整Laravel控制器，因为在我从存储请求的文件之外，它不依赖任何内容，可以运行，并且可以用来确认它是否是问题，或者可能会发生什么。最后，我将文件的一些输出包含在存储中。

            // ISSUE in the old application size max is set to 1000 and response is
            // prompt like the examples in PHP playground, but can't get higher than 
            // 50-100 without timing out in Laravel, which greatly decreases the result 
            // set. Both these examples work using a size max of 1000, but when used
            // in Laravel the response timesout.
            //
            // Example fiddle using old code:
            // https://www.tehplayground.com/XYXERmL9kHmdTvLD
            //
            // Example fiddle using paired down code from this class in Laravel:
            // https://www.tehplayground.com/N2T3PTQSBfaWSQPh
            50, // Size max

            true, // Metadata
            '',   // Specific fields in result (CSV)
            'asc' // Sort order
        ];

        try {
            $client = new SoapClient($wsdl);
            return $client->search(...$params);
        } catch (\Exception $ex) {
            Log::error($ex);

            throw $ex;
        }
    }
}

从getTidalRegions返回的数据示例，如果有人愿意测试控制器，则可以直接从getTidalRegions返回该数据，并替换来自Storage的请求。
