使用Nancy返回包含有效Json的字符串 [英] Returning a string containing valid Json with Nancy

问题描述

我从另一个服务收到一个包含有效JSON的字符串. 我只想用Nancy转发此字符串，还要将content-type设置为"application/json"，这将使我不再需要在客户端使用$ .parseJSON(data).

I receive a string that contains valid JSON from another service. I would like to just forward this string with Nancy but also set the content-type to "application/json" which will allow me to remove the need for using $.parseJSON(data) on the client side.

如果我使用Response.AsJson，它似乎会弄乱字符串中的JSON并添加转义字符. 我可以使用字符串创建Stream并设置响应类型，例如:

If I use Response.AsJson it seems to mangle the JSON in the string and adds escape characters. I could create a Stream with the string and set the response type something like:

Response test = new Response();
test.ContentType = "application/json";
test.Contents = new MemoryStream(Encoding.UTF8.GetBytes(myJsonString)); 

但想知道是否有更简单的方法?

but would like to know if there is a simpler way?

推荐答案

我喜欢您认为应该有一个更好的方法，因为您必须使用3行代码，我认为这与Nancy有关:-)

I like that you think there should be a better way because you're having to use 3 lines of code, I think that says something about Nancy :-)

我想不出一种更好"的方法，您可以使用GetBytes方法:

I can't think of a "better" way to do it, you can either do it the GetBytes way:

Get["/"] = _ =>
    {
        var jsonBytes = Encoding.UTF8.GetBytes(myJsonString);
        return new Response
            {
                ContentType = "application/json",
                Contents = s => s.Write(jsonBytes, 0, jsonBytes.Length)
            };
    };

或投射字符串"方式:

Get["/"] = _ =>
    {
        var response = (Response)myJsonString;

        response.ContentType = "application/json";

        return response;
    };

两者都做同样的事情-后者代码更少，前者更具描述性(imo).

Both do the same thing - the latter is less code, the former more descriptive (imo).
