Recommended: use 【raw string literals】 to set JSON

We recommend using raw string literals to set JSON data. In C# 11, this feature was introduced, allowing strings wrapped in three double quotes (""") to contain multi-line text, while escape characters within the string (such as \n, \t, etc.) are treated as ordinary characters without needing to be escaped. For example:

HttpRequestBuilder.Post("https://furion.net/")    .SetJsonContent("""                    {                        "id": 1,                        "name": "Furion"                    }                    """);

If you need to insert a variable into the raw string, simply add $$ before the first """ and use the {{variableName}} template as a placeholder. For example:

123456789

var val = "Furion";HttpRequestBuilder.Post("https://furion.net/")    .SetJsonContent($$"""                        {                            "id": 1,                            "name": "{{val}}"                        }                        """);

Using raw string literals to set JSON data simplifies the code and avoids the tedious handling of escape characters.
