如何解决特殊字符的 JSON 响应？

如何解决特殊字符的 JSON 响应？

当我将 Postman 工具与此 URL 一起使用时，我会收到有效且预期的 JSON。

但是，当我在 .Net 中使用此 URL 发出 HTTP 请求时，我会收到包含特殊字符的响应。

代码如下：

    let url =      String.Format(TagsUrl, pageNumber |> string)
    let client =   httpClient APIBaseAddress
    let response = client.GetAsync(url) |> Async.AwaitTask 
                                        |> Async.RunSynchronously

   if response.IsSuccessStatusCode
         then let json =   response.Content.ReadAsStringAsync() |> Async.AwaitTask |> Async.RunSynchronously
              let result = JsonConvert.DeserializeObject<Response>(json)
              let tags =   result.items |> List.ofSeq 
                                        |> List.map (fun i -> i.name)
              tags
         else []

我也尝试以字节数组的形式读取响应，但结果相同：

let url =      String.Format(TagsUrl, pageNumber |> string)
let client =   httpClient APIBaseAddress
let response = client.GetByteArrayAsync(url) |> Async.AwaitTask 
                                             |> Async.RunSynchronously

let json = Encoding.UTF8.GetString(response);

let result = JsonConvert.DeserializeObject<Response>(json)

let TagsUrl = "2.2/tags?page={0}&order=desc&sort=popular&site=stackoverflow&filter=!-.G.68grSaJm"

[<Literal>]
let APIBaseAddress = "https://api.stackexchange.com/"

type Item =     { name : string }
type Response = { items: Item list }

您可以使用the F# Data library 中的Http 实用程序。以下对我有用：

Http.RequestString
  ( "https://api.stackexchange.com/2.2/tags" + 
    "?page=1&order=desc&sort=popular&site=stackoverflow&filter=!-.G.68grSaJm")
