Well, like the error says, your JSON is invalid.
好吧，就像错误所说的那样，您的 JSON 无效。
Constructing JSON manually is a really bad idea. It's far harder to construct, and you're prone to parse errors. Instead, build your data programmatically as an array or object then use json_encode().
手动构建 JSON 是一个非常糟糕的主意。构建起来要困难得多，而且您很容易出现解析错误。相反，以编程方式将数据构建为数组或对象，然后使用json_encode().
