Question

有人可以向我解释PayPal示例中这些字符串值中“+”和“ - ”的重要性吗？ PayPal文档实际上没有在API文档中解释这一点。

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

我发现某些值是URL编码的，而其他值则使用这些“+”和“ - ”字符而不是URL编码。

为什么？

由于

首先，-符号不需要进行URL编码。实际上，如果您查看此页面的网址，则会看到https://stackoverflow.com/questions/12626956/paypal-invoicing-api-requests-formatting，其中包含大量-个符号。

其次，空格可以由+或%20表示，具体取决于它在网址中的位置。引自this answer：

+ 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'.

因此，对于您的示例，Banana+Leaf+--+001会转换为Banana Leaf -- 001和 Banana+Leaf转换为Banana Leaf。
