偏移37处的非法字符“ X”

Question

我正在使用带有cURL的xml来联系加拿大邮政并获得运输标签。

这是我使用的代码。

平台是ExpressionEngine

<?php
 /**

 * Use your development key username and password for the web service credentials.

我在下面收到错误

HTTP响应状态：500错误代码：服务器错误消息：/ rs / 0000000000/0000000000 / shipment的偏移量37处的非法字符“ X”

（我将客户号更改为“ 0000000000”）

有人可以解释以上消息的含义吗？

非常感谢你

Answer 1

该提供程序可能（如所有 “企业”提供程序）未使用适当的XML解析器。 尝试在PI的结束字符之前放置一个空格，否则将无法完全删除该PI。

Answer 2

37个字符将您置于XML Prolog的末尾

<?xml version="1.0" encoding="UTF-8"?>

主机不能处理此问题，或者您可能有DOS / UNIX终端问题。

首先，尝试删除XML Prolog，看看是否有帮助。

如果那没有帮助，则（取决于您的编辑器）将PHP源代码另存为UNIX文件，以使行尾标记正确。 如果这不起作用，请尝试将其另存为DOS文件。
