【问题描述】：
图片无法访问数据库
我的 doInBackground() 方法
try {
File file_name=new File("/storage/sdcard1/Received/IAF-Sarang.jpg");
DefaultHttpClient mHttpClient;
HttpParams par = new BasicHttpParams();
par.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
mHttpClient = new DefaultHttpClient(par);
try {
HttpPost httppost = new HttpPost("http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/?");
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("post_id", new StringBody("1368"));
multipartEntity.addPart("user_id", new StringBody("62"));
multipartEntity.addPart("files", new FileBody(file_name, "Content-Type: image/jpeg\r\n\r\n"));
httppost.setEntity(multipartEntity);
mHttpClient.execute(httppost, new PhotoUploadResponseHandler());
} catch (Exception e) {
e.printStackTrace();
System.out.println(""+e);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return response_string;
这是 PhotoUploadResponseHandler 类
private class PhotoUploadResponseHandler implements ResponseHandler<Object> {
@Override
public Object handleResponse(HttpResponse response)
throws ClientProtocolException, IOException {
HttpEntity r_entity = response.getEntity();
String rString = EntityUtils.toString(r_entity);
Log.d("UPLOAD", rString);
response_string=rString;
return rString;
}
}
我已经尝试了另外一个代码块，但没有达到 post_id
图片发布成功

您可能想要更好地解释实际问题。使用一小段代码来解释你在做什么，而不是转储你的代码，看看这个sscce.org。还要尝试解释代码的预期内容以及实际发生的情况。
