Requests库发送post请求，传入接口参数后报JSON parse error

报错信息：

{"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：发送post请求，传入参数，想当然的以为是{}形式，结果调用的接口是[{}]形式，对接口了解不够。
