推荐答案

I建议您阅读 PayPal文档 [ ^ ]和下载示例代码 [ ^ ]。



注意：字符串连接（由您使用）不正确。

为什么？ 字符串 [ ^ ]是不可变的！请参考：为什么字符串是不可变的，什么是它的含义是什么？ [ ^ ]

I'd recommend you to read PayPal documentation[^] and download sample code[^].

Note: string concatenation (used by you) is incorrect.
Why? String[^] is immutable! Please, refer this: Why strings are immutable and what are the implications of it?[^]
