在 vb.net、js 或 pythom 中发出一个响应 json 字符串的 get 请求

问题描述

我正在尝试制作一个 github OAuth，但它需要一些帖子并获得回复。 那么我如何向特定 url 发出获取请求，然后以 json 的形式获取响应， 这是我试过的代码：

Dim logincookie As CookieContainer
    Dim rqtp As Integer
        Dim postReq As HttpWebRequest = DirectCast(WebRequest.Create(TextBox1.Text),HttpWebRequest)
                Dim postData As String = TextBox1.Text
                Dim encoding As New UTF8Encoding
                Dim byteData As Byte() = encoding.GetBytes(postData)
                Dim tempCookies As New CookieContainer
                postReq.Method = "GET"
                postReq.KeepAlive = True
                postReq.CookieContainer = tempCookies
                postReq.ContentType = "application/xml"
                postReq.Referer = TextBox1.Text
                postReq.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729)"
                postReq.ContentLength = byteData.Length
                Dim postreqstream As Stream = postReq.GetRequestStream()
                postreqstream.Write(byteData,byteData.Length)
                postreqstream.Close()
                Dim postresponse As HttpWebResponse

                postresponse = DirectCast(postReq.GetResponse(),HttpWebResponse)
                tempCookies.Add(postresponse.Cookies)
                logincookie = tempCookies
                Dim postreqreader As New StreamReader(postresponse.GetResponseStream())

                Dim thepage As String = postreqreader.ReadToEnd

                response.Text = thepage
                Clipboard.Clear()
                Clipboard.SetText(thepage)
                MsgBox(thepage,vbInformation + vbOK,"result")

如果你愿意，你也可以看到 repo，这样你就可以看到完整的项目:)

解决方法

理想情况下，将该字符串反序列化为复合对象或动态对象。您可能会使用 JavaScriptSerializer 或 NewtonSoft 库来实现这一点并将该对​​象序列化为 json。
