Question

我想以字节格式向android app中的服务器发送字符串数据“”。我使用的是HttpClient，但我觉得它不是正确的方法，请帮我怎么做？

如果是.net，我想在java中使用类似的代码。

    string boundary = Guid.NewGuid().ToString();
    HttpWebRequest request = HttpWebRequest.Create(url)
        as HttpWebRequest;
    request.Method = "POST";
    //request.ContentType = "application/json";
    request.PreAuthenticate = true;

    byte[] fulldata = Encoding.UTF8.GetBytes(data);
    request.ContentLength = fulldata.Length;
    using (Stream sw = request.GetRequestStream())
    {
        sw.Write(fulldata, 0, fulldata.Length);
    }

首先将字符串数据转换为字节，然后使用ByteArrayEntity以字节格式将数据发送到服务器。

试试这个

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.1.1/xxx");
HttpResponse response;
HttpParams hp = new BasicHttpParams();

//use ByteArrayEntity to send string data in byteformat
ByteArrayEntity byteEntity = new ByteArrayEntity(byte_data);
httppost.setEntity(byteEntity);
response = httpclient.execute(httppost);

如何以字节格式将字符串数据发布到服务器？
