ServicePointManager等价于java

Question

我正试图将一个VB.net项目转换为一个Androidapp.i的java。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

此代码发送一个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。除这两行外，所有部分都是清楚的。

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

有谁知道它在java中的等价物吗?您的帮助是非常感谢的。

经过大量的搜索和学习，我得出的结论是，除了将ServicePointManager.Expect100Continue = True ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3安全协议设置为SSL3之外，没有直接等效的SSL3协议，我们可以使用

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

希望这能帮到你
