如何正确解析Javascript中的view_state

Question

我使用view_state RPC方法并通过JavaScript解析响应。然而，它似乎大多数返回的结果是非常有用的。是否有明确可打印文本的示例或分析数据的另一种方法？

const contract = await this.props.near.connection.provider.sendJsonRpc('query', { request_type: 'view_state', finality: 'final', account_id: 'blazenet', prefix_base64: '' });

let contractParsed = contract.values.map((data, i) => {
  return { 'key': atob(data.key).replace(/[^\x20-\x7E]/g, ""), 'val': atob(data.value).replace(/[^\x20-\x7E]/g, "") };
});

解析响应：

0: {key: "STATE", val: "blaze.betanet!as+vGj"JV0hxX_/b@zHQXz{Q?!p^/b@zHduiukuv"}
1: {key: "ui ]qU2s7AG5|c7`-?", val: ""}
2: {key: "ui bJ+e,-,[y]CsKUB", val: ""}
3: {key: "ui *EDfC*,#,/", val: ""}
4: {key: "ui ZB\[`VR\/a", val: ""}
5: {key: "ui _|XW==. 0M$l", val: ""}
6: {key: "ui \;>bR?{Ut7/Q", val: ""}
7: {key: "uk", val: " ZB\[`VR\/a"}
8: {key: "uk", val: " \;>bR?{Ut7/Q"}
9: {key: "uk", val: " ]qU2s7AG5|c7`-?"}
10: {key: "uk", val: " *EDfC*,#,/"}
11: {key: "uk", val: " _|XW==. 0M$l"}
12: {key: "uk", val: " bJ+e,-,[y]CsKUB"}
13: {key: "uv", val: "i\s1"}
14: {key: "uv", val: "z-:HYc:"}
15: {key: "uv", val: "Z|"}
16: {key: "uv", val: "Vk/"}
17: {key: "uv", val: "ESQlVA"}
18: {key: "uv", val: "`>(u{|{"}

key和value都用base64编码。

键和值可以用Borsh序列化，为了反序列化它，您需要知道每个键和值的架构。阅读更多关于https://borsh.io的信息
