下面是从连接到网站并通过 POST 方法上传文件的 Java 客户端的片段。我必须在 Visual Studio 环境中重现此客户端，但在 Java 中使用的setEntity()函数在 .NET 环境中看不到任何等效函数。

我发现的一切都指向使用这个......

public void uploadFile(File uploadFile, String partner, String key,
            String baseUrl,boolean isPartner) throws IOException {
    DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getParams().setParameter(
        CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1
    );
    String url = baseUrl + "?" + (isPartner ? "partnerId" : "ori") + "="
            + partner.toUpperCase() + "&authKey=" 
            + key+ "&key=" 
            + key;
    HttpPost httppost = new HttpPost(url);
    MultipartEntity multipartEntity = new MultipartEntity();
    ContentBody contentBody = new FileBody(uploadFile, "text/xml"); 
    multipartEntity.addPart("dataFile", contentBody); 
    httppost.setEntity(multipartEntity);

    HttpResponse response;
    response = httpclient.execute(httppost);

    HttpEntity resEntity = response.getEntity();

    if (resEntity != null) {
        resEntity.consumeContent();
    }

    httpclient.getConnectionManager().shutdown();
}

我在 Visual Studio 中找到的所有东西都使用下面这样的 POST 方法。WebRequest对象没有明显的方法来添加我需要的参数 。

Dim request As WebRequest = WebRequest.Create("http://Test.com/import?partnerId=2&authKey=XdUa")
request.Method = "POST"
Dim postData As String = StrData
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)
request.ContentType = "dataStr"
request.ContentLength = byteArray.Length
Dim dataStream As Stream = request.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
Dim response As WebResponse = request.GetResponse()

任何指导将不胜感激。如果我的问题不清楚，请告诉我，我会再试一次。

您可以添加以下代码片段来添加参数

request.ContentType="应用程序/x-www-form-urlencoded"

将 postData 调暗为 String = "name1="+value1+"&name2="+value2

Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)

休息将保持不变。
