当 json-rpc 传入的数组中有回车时，Json格式化错误

[chenzhitong]

当 json-rpc 请求的数组中有回车或换行时，服务器会返回错误（-32700 Parse error）。

{
  "jsonrpc": "2.0",
  "method": "sendmany",
  "params": [[
  	{"asset": "025d82f7b00a9ff1cfe709abe3c4741a105d067178e645bc3ebad9bc79af47d4","value": 1,"address": "AbRTHXb9zqdqn5sVh4EYpQHGZ536FgwCx2"},{"asset": "025d82f7b00a9ff1cfe709abe3c4741a105d067178e645bc3ebad9bc79af47d4","value": 1,"address": "AbRTHXb9zqdqn5sVh4EYpQHGZ536FgwCx2"}]],
  "id": 1
}

将数组中的回车删掉，服务器会返回正确结果

{
  "jsonrpc": "2.0",
  "method": "sendmany",
  "params": [[{"asset": "025d82f7b00a9ff1cfe709abe3c4741a105d067178e645bc3ebad9bc79af47d4","value": 1,"address": "AbRTHXb9zqdqn5sVh4EYpQHGZ536FgwCx2"},{"asset": "025d82f7b00a9ff1cfe709abe3c4741a105d067178e645bc3ebad9bc79af47d4","value": 1,"address": "AbRTHXb9zqdqn5sVh4EYpQHGZ536FgwCx2"}]],
  "id": 1
}

估计是 JSON 解析的时候出错的，当用 Newtonsoft Json.NET 解析时不会出错。

更简单的测试用例：

{
  "jsonrpc": "2.0",
  "method": "getblockcount",
  "params": [
  	],
  "id": 1
}

JSON 解析错误

{
  "jsonrpc": "2.0",
  "method": "getblockcount",
  "params": [],
  "id": 1
}

JSON 解析正确

It seems if you put a "\t" character into the JSON string, you will get this error.
