連接在一個屏幕上成功下載，在第二個屏幕上出現幾乎相同的代碼錯誤

我試圖從兩個不同屏幕上的相同php文件下載「成功」消息時發生奇怪事件，這兩個屏幕都具有相同的連接代碼。每個頁面都有一個連接並返回成功的按鈕以及php文件的信息。任何想法爲什麼發生這種情況？連接都是成功的，在兩種情況下都會返回200。連接在一個屏幕上成功下載，在第二個屏幕上出現幾乎相同的代碼錯誤

AppInfo返回「成功」購買返回此：

查看錯誤消息，特別是FailedURI：

FailedURI=http%3A%2F%2Fsinfo.txt%2Ftest.php

您正在嘗試點擊http://sinfo.txt/test.php。由於該主機名顯然不存在，因此您正在獲取ISP的dns重定向頁面。

修復您的代碼，然後大吼你的ISP並禁用DNS重定向。
