当一个参数的值被解码为字符串的 JSON 值时，我在 WebClient 编码查询参数时遇到问题。

queryParams 值之一是：

[ { "var": "report_days", "op": "=", "val": "7" } ]\n

它是从 HTTP 方法解码的： ? filter=%5B%7B%22var%22%3A%22report_days%22%2C%22op%22%3A%22%3D%22%2C%22val%22%3A%227%22%7D%5D.\n因此解码到MultiMap<String, String>正确执行，但在uriBuilder抛出异常。

[ { "var": "report_days", "op": "=", "val": "7" } ]\n

例外：
