如何在 C# 中的 JSON-RPC 2.0 中编写 "params"?

How to write "params" in JSON-RPC 2.0 in C#?

我想使用JSON-RPC 来控制名为aria2 的应用程序。当它不需要参数时我可以控制它。但是我尝试了很多方法,我从来没有成功地用params控制它。

我试过的一些代码是这样的:

if (secret != null && secret != "")
    json = JsonConvert.SerializeObject(new JObject { ["jsonrpc"] = "2.0", ["id"] = "m", ["method"] = "aria2.addUri", ["params"] = { "token:" + secret, "[http://csharp.org/file.zip]" } });
else
    json = JsonConvert.SerializeObject(new JObject { ["jsonrpc"] = "2.0", ["id"] = "m", ["method"] = "aria2.addUri", ["params"] = @"[http://csharp.org/file.zip]" });

我也试过:

if (secret != null && secret != "")
    string json = "{\"jsonrpc\": \"2.0\",\"method\": \"aria2.addUri\",\"params\": {\"token:\"" + secret + "\",\"http://csharp.org/file.zip\"},\"id\": \"m\"}";
else
    string json = "{\"jsonrpc\": \"2.0\",\"method\": \"aria2.addUri\",\"params\": {\"http://csharp.org/file.zip\"},\"id\": \"m\"}";

而且我已经尝试了很多 [{'" 的组合和排列,但没有任何效果。

Here is the RPC guide about aria2 for Python: https://aria2.github.io/manual/en/html/aria2c.html#rpc-authorization-secret-token

这里是一些初学者可能想知道的解决方案。

First, know what you want to output, in this case is:

{"jsonrpc":"2.0","id":"m","method":"aria2.addUri","params":["token:secret",["http://csharp.org/file.zip"]]}

然后,小提示 [] 在参数值之外,所以它们是数组,而不是字符串。它不能使用["params"] = {},也不会覆盖字符串到数组,例如下面的错误代码:

JsonConvert.SerializeObject(new JObject { ["params"] = "[\"token:secret\", [\"http://csharp.org/file.zip\"]]" });

只得到:

{"params":"[\"token:secret\", [\"http://csharp.org/file.zip\"]]"}

The most important is the format of token, it's not a JProperty() in JObject(), it's just a string in params's JArray(). And uri is also in params's JArray()'s JArray(). So the right version is:

JArray param = new JArray { "token:secret", new JArray { "http://csharp.org/file.zip" } };
string json = JsonConvert.SerializeObject(new JObject { ["jsonrpc"] = "2.0", ["id"] = "m", ["method"] = "aria2.addUri", ["params"] = param });
  • JArray()[]JObject(){}JArray()JObject().

If we don't need JsonConvert(), the right version is easy:

string json = "{ \"jsonrpc\": \"2.0\", \"id\": \"m\", \"method\": \"aria2.addUri\", \"params\": [\"token:secret\", [\"http://csharp.org/file.zip\"]] }";
  • 在这种情况下,我们无法将 " 更改为 '
