Requests庫發送post請求，傳入接口參數后報JSON parse error

報錯信息：

{"timestamp":"2020-01-08T14:42:40.894+0000","status":400,"error":"Bad Request","message":"JSON parse error: Cannot deserialize instance of `java.util.ArrayList` out of VALUE_STRING token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.util.ArrayList` out of VALUE_STRING token\n at [Source: (PushbackInputStream); line: 1, column: 1]","path":"/home/brand/create"}

原因：發送post請求，傳入參數，想當然的以為是{}形式，結果調用的接口是[{}]形式，對接口了解不夠。
