我得到的回报就像 pdf 的实际内容,但是当我尝试创建一个 pdf 文件并将此数据粘贴到文本编辑器上并将其保存为 pdf 时,当我尝试打开它时,它只是说文件无法打开。

这是我尝试创建的 pdf 文件的示例数据:

我不确定我是否仍然需要解析数据或对其进行编码,或者 php 中是否有某种工具来呈现这种类型的响应?

任何帮助将非常感激。谢谢

您在此处发布的内容确实是 PDF 文件的一小部分。您在此处粘贴的是文件的开头(看起来合法)和 XObject 的第一部分 - 这是 PDF 语言,在这种情况下用于表示图像。如果您想对这个文件做一些有用的事情,请注意两点:

1) 您在这里所拥有的只是很小的一部分——您需要完整的 PDF 文件才能对其进行任何操作。

2) 行尾在 PDF 中很重要,因为文件格式适用于对象和文件末尾的交叉引用表,其中包含所有对象的字节偏移量。因此,如果您搞砸了行尾,则任何偏移都不会起作用,并且您自己的 PDF 文件已损坏。如果您将传入的数据视为二进制数据并将其写入文件未更改,通常您应该得到一个好的 PDF 文件(假设他们向您发送完整的文件而不是您在此处显示的片段)。
