我正在尝试将 VB.net 项目转换为用于 android 应用程序的 java。我被困在某个时刻。 我的 VB.net 代码是

Public Function SendWebRequest(ByVal url As String, ByVal postData As String, ByVal TimeOut As String, ByVal Code As String) As String
    Dim result As String
    Try


        postData = "Some String" + postData


        Dim webRequest As WebRequest = webRequest.Create(url)
        webRequest.Method = "POST"
        webRequest.Timeout = IntegerType.FromString(TimeOut)
        webRequest.Headers.Add(name1, value1)

         'problem is here
        ServicePointManager.Expect100Continue = True
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3

        Dim bytes As Byte() = System.Text.Encoding.UTF8().GetBytes(postData) 'Encoding.get_UTF8().GetBytes(postData)
        webRequest.ContentType = "application/x-www-form-urlencoded"
        webRequest.ContentLength = CLng(bytes.Length()) 'CLng(bytes.get_Length())
        Dim stream As Stream = webRequest.GetRequestStream()
        'stream.Write(bytes, 0, bytes.get_Length())
        stream.Write(bytes, 0, bytes.Length())
        stream.Close()
        Dim response As WebResponse = webRequest.GetResponse()
        stream = response.GetResponseStream()
        Dim streamReader As StreamReader = New StreamReader(stream)
        Dim text As String = streamReader.ReadToEnd()
        streamReader.Close()
        stream.Close()
        response.Close()
        result = text
    Catch expr_1AA As Exception
        Dim ex As Exception = expr_1AA
        Console.WriteLine("Exception ReadSecConn:" + ex.Message())
    End Try
    Return result
End Function

此代码发送 Web 请求。我已经使用 json 成功地将我的 android 应用程序的 web 请求发送到 web 服务器。除了这两行之外，所有部分都清楚

 ServicePointManager.Expect100Continue = True
 ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3

有没有人知道它在java中的等价物，您的帮助将不胜感激

经过大量搜索和学习后，我得出结论，没有直接等效的 ServicePointManager.Expect100Continue = True ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 但是对于将安全协议设置为 SSL3 ，我们可以使用

System.setProperty("https.protocols", "SSLv3");

希望这可以帮助你
