有人可以向我解释 PayPal 示例中这些字符串值中“+”和“-”的意义吗？PayPal 文档确实没有在 API 文档中解释这一点。

&invoice.itemList.item(0).name=Banana+Leaf+--+001 
&invoice.itemList.item(0).description=Banana+Leaf

我看到一些值是 URL 编码的，而另一些值是这些“+”和“-”字符而不是 URL 编码。

为什么？

谢谢

首先，-符号不需要进行 URL 编码。事实上，如果您查看此页面的 URL，您会看到https://stackoverflow.com/questions/12626956/paypal-invoicing-api-requests-formatting其中有很多-符号。

其次，一个空间可以由+或者%20取决于它在 URL 中的位置来表示。引用这个答案：

+ means a space only in application/x-www-form-encoded content,
such as the query part of a URL:

http://www.example.com/path/foo+bar/path?query+name=query+value

In this URL, the parameter name is 'query name' (with a space) and
the value is 'query value' (with a space), but the folder name in
the path is literally foo+bar, not 'foo bar'.

所以用你的例子，Banana+Leaf+--+001翻译Banana Leaf -- 001和 Banana+Leaf翻译成Banana Leaf.
