我想在 android 中使用 http post 发布多字节数组。我成功地使用 BYTEARRAYENTITY 发布单字节数组但是在单个请求中发布多字节数组应该在代码中进行哪些更改？

我编写如下代码，可以很好地发布一个字节数组。但等待解决方案发布多字节数组。

public String postData2s(String URL, String data) {
    String filesizes = "";
    BufferedReader bufferedReader = null;
    String strresponse = "";
    byte[] byteArray = null;
    byteArray = data.getBytes();
    filesizes = byteArray.length + "";
    URL = URL + "&" + "fileSizes=" + filesizes;
    final DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpPost request = null;
    try {
        request = new HttpPost(URL);
    } catch (Exception e) {

    }
    HttpResponse response = null;
    ByteArrayEntity arrayEntity = new ByteArrayEntity(byteArray);
    try {
        arrayEntity.setContentType("text/xml");
        request.setEntity(arrayEntity);
        response = httpClient.execute(request);
        bufferedReader = new BufferedReader(new InputStreamReader(response
                .getEntity().getContent()));
        StringBuffer stringBuffer = new StringBuffer("");
        String line = "";
        String LineSeparator = System.getProperty("line.separator");
        while ((line = bufferedReader.readLine()) != null) {
            stringBuffer.append(line + LineSeparator);
        }
        bufferedReader.close();
        Log.e("response ", stringBuffer.toString());
        strresponse = stringBuffer.toString();
    } catch (ClientProtocolException e) {
        strresponse = "";
        e.printStackTrace();
    } catch (IOException e) {
        strresponse = "";
        e.printStackTrace();
    } finally {
        if (bufferedReader != null) {
            try {
                bufferedReader.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
    return strresponse;
}

我的 C# 同事使用以下代码为 windows 发布多字节数组

 webRequest.ContentLength = size;

                Stream requestStream = webRequest.GetRequestStream();

                // Escribo cada uno de los archivos en el stream

                for (int i = 0; i < arrBytes.Length; i++)

                    requestStream.Write(arrBytes[i], 0, arrBytes[i].Length);

                requestStream.Close();

如果有人对此有任何想法，请尽快回复我

谢谢

我正在使用以下方法发布数据。它还包括 byteArray 作为字符串格式的字段之一。您可以将多个字段与多个字节数组一起使用，它会完成这项工作。

代码：

public static String UpdateUser(String userIdValue, String userNameValue, String nameValue,
        String emailIdValue, String contryIdValue,String countryNameValue, String stateValue, String cityValue ,String imageBytes){
    String res = null;

    HttpPut request = new HttpPut(USER_URL);
    //request.setHeader("Accept", "application/json");
    request.setHeader("Content-type", "application/json");
    //request.setHeader("user-agent", "Yoda");
    try {

        //-----------------
        /*InputStream is = new BufferedInputStream (getResources().openRawResource(R.drawable.images));
        JSONArray array=readBytes(is);
        is.close(); */
        //----------------
        // Build JSON string
        JSONStringer jObject = new JSONStringer()
            .object()
                //.key("Get")
                  //  .object()
                        .key("Userid").value(userIdValue)
                        .key("UserName").value(userNameValue)
                        .key("Name").value(nameValue)
                        .key("EmailId").value(emailIdValue)
                        //.key("Password").value("")
                        .key("CountryId").value(contryIdValue)
                        .key("CountryName").value(countryNameValue)
                        .key("State").value(stateValue)
                        .key("City").value(cityValue)
                        .key("ImageByteArray").value(imageBytes)
                        /*.key("UserVerification").value("")
                        .key("City").value("")
                        .key("City").value("")*/
                   // .endObject()
                .endObject();

        StringEntity entity = new StringEntity(jObject.toString());
        //System.out.println("Our Res: "+jObject.toString());

        request.setEntity(entity);

        // Send request to WCF service
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpResponse response = httpClient.execute(request);
        //res = response.toString();
        int resCode = response.getStatusLine().getStatusCode();
        System.out.println("Our Res: "+jObject.toString());
        System.out.println("Result code: "+resCode);

        BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        String line="";
        StringBuffer returnFromServer = new StringBuffer();
        while ((line=in.readLine())!=null){
            returnFromServer.append(line);
        }
        //Toast what we got from server
        //Toast.makeText(getApplicationContext(),returnFromServer.toString(), Toast.LENGTH_LONG).show(); 
        System.out.println("Responce: "+returnFromServer.toString());
        res = returnFromServer.toString();

        if (entity != null){
            entity.consumeContent();
        }
        // Toast.makeText(getApplicationContext(),response.getStatusLine().getStatusCode()+"", Toast.LENGTH_LONG).show();
    }catch(Exception e){
        e.printStackTrace();
    }

    System.out.println("Responcre is:"+res);
    return res;

}

您只需要添加额外的参数作为您拥有的 byteArray 的数量。

希望对你有很大帮助。

享受编码。
