Question

我正在使用api（使用curl和php），它应该根据日期返回一批csv记录。首先，您发出一个请求，返回批次中的记录数。第二个请求是实际检索记录。我的问题是当我发出第二个请求时，我没有得到第一个请求表明我要获得的记录数。无论选择的日期如何，我总是获得7167条记录（任何特定日期的记录数量将超过8000条）。我收到的内容长度是我要获得的标题。我没有得到任何错误。如果我把url请求放在浏览器的地址栏中，我就得到了我应该得到的所有记录。

该脚本在Linux平台上运行。事实上，我已经在另一台具有相同结果的Linux服务器上尝试过它。我尝试过更改执行时间和超时设置。我真的很困惑。提前感谢您的建议。
