保存图片.php

<?php

}

出现错误

试试{ 响应 = httpclient.execute(httppost); } 捕捉（ClientProtocolException e）{ // TODO 自动生成的 catch 块 e.printStackTrace(); }

请帮我解决..

Answer 1

为我工作，请尝试使用不同的网络，如 wifi 或移动数据

// 调用服务器

HttpResponse 响应 = httpclient.execute(httppost); HttpEntity r_entity = response.getEntity();

          int statusCode = response.getStatusLine().getStatusCode();
          if (statusCode == 200) {
              // Server response
              responseString = EntityUtils.toString(r_entity);
          } else {
              responseString = "Error occurred! Http Status Code: "
                      + statusCode;
          }           } catch (ClientProtocolException e) {
          responseString = e.toString();          } catch (IOException e) {
          responseString = e.toString();          }           return responseString;

您可以使用此方法将图像发送到服务器

public class JSONParser {

static InputStream is = null;
static JSONObject jObj = null;
static String json = "";


public static JSONObject sendJSONDataWithImage() {

    String Content = null;

    DefaultHttpClient httpClient = new DefaultHttpClient();

    HttpPost httpPost = new HttpPost("http://192.168.8.84:8003/savetofile.php");

    File file = new File(yourFilePathwithfileName);
    MultipartEntity reqEntity = new MultipartEntity(
            HttpMultipartMode.BROWSER_COMPATIBLE);

    Charset chars = Charset.forName("UTF-8");

    int size = (int) file.length();
    byte[] bytes = new byte[size];
    ByteArrayBody bab = null;
    try {
        BufferedInputStream buf = new BufferedInputStream(
                new FileInputStream(file));
        buf.read(bytes, 0, bytes.length);
        buf.close();
        bab = new ByteArrayBody(bytes, yourFilePathwithfileName);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
        // reqEntity.addPart("user_id", new StringBody(otherParameter,chars));

    } catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
    }
    reqEntity.addPart("myFile", bab);

    httpPost.setEntity(reqEntity);

    // execute HTTP post request
    HttpResponse response;
    try {
        response = httpClient.execute(httpPost);
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                response.getEntity().getContent(), "UTF-8"));

        StringBuilder s = new StringBuilder();
        String sResponse;
        while ((sResponse = reader.readLine()) != null) {
            s = s.append(sResponse);
        }
        json = s.toString();

        System.out.println("Response.............: " + json);
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
         jObj = new JSONObject(json);
         Log.e("add emp with img Response", "> " + json.toString());
     } catch (JSONException e) {
         Log.e("JSON Parser", "Error parsing data " + e.toString());
     }

    return jObj;
}

}

在你的 android 中试试这个简单的代码，它对我有用，

    String url = "";// URL where image has to be uploaded
    String fileName = ""; //path of file to be uploaded
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);
    FileBody fileContent = new FiSystem.out.println("hello");
    StringBody comment = new StringBody("Filename: " + fileName);
    MultipartEntity reqEntity = new MultipartEntity();
    reqEntity.addPart("file", fileContent);
    httppost.setEntity(reqEntity);

    HttpResponse response = httpclient.execute(httppost);
    HttpEntity resEntity = response.getEntity();

希望这可以帮助您解决问题...!!!!!
