我正在尝试使用MultipartEntity发送图像和纬度和经度值。纬度和经度值存储在名为plat和plong的单独变量中。我能够将图像发送到服务器,但不能同时发送纬度和经度。在服务器端,只有纬度最终插入数据库。贝娄是我用来将文件和字符串发送到服务器的代码。谁能建议我做错了什么?
private class UploadTask extends AsyncTask<Bitmap, Void, Void> {
protected Void doInBackground(Bitmap... bitmaps) {
if (bitmaps[0] == null)
return null;
setProgress(0);
Bitmap bitmap = bitmaps[0];
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); // convert
// Bitmap
// to
// ByteArrayOutputStream
InputStream in = new ByteArrayInputStream(stream.toByteArray()); // convert
// ByteArrayOutputStream
// to
// ByteArrayInputStream
DefaultHttpClient httpclient = new DefaultHttpClient();
try {
HttpPost httppost = new HttpPost(
"http://www.example.com/index.php"); // server
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("myFile",
System.currentTimeMillis() + ".jpg", in);
httppost.setEntity(reqEntity);
reqEntity.addPart("long",String.valueOf(plong));
reqEntity.addPart("lat",String.valueOf(plat));
Log.e(TAG, "request " + httppost.getRequestLine());
HttpResponse response = null;
try {
response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
if (response != null)
Log.i(TAG, "response "
+ response.getStatusLine().toString());
} finally {
}
} finally {
}
if (in != null) {
try {
in.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if (stream != null) {
try {
stream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return null;
}
以下是MultipartEntity类中的addPart()方法。
ByteArrayOutputStream out = new ByteArrayOutputStream();
public void addPart(final String key, final String value) {
writeFirstBoundaryIfNeeds();
try {
out.write(("Content-Disposition: form-data; name=\"" +key+"\"\r\n").getBytes());
out.write("Content-Type: text/plain; charset=UTF-8\r\n".getBytes());
out.write("Content-Transfer-Encoding: 8bit\r\n\r\n".getBytes());
out.write(value.getBytes());
out.write(("\r\n--" + boundary + "\r\n").getBytes());
} catch (final IOException e) {
}
}
最佳答案
试试这个
reqEntity.addPart("long",new StringBody(plong));
reqEntity.addPart("lat",new StringBody(plat));
// or plong.toString() and plat.toString() depending on your plong and plat datatype
//and then add to httppost
httppost.setEntity(reqEntity);
发送纬度和经度。
但是,您可以查看,这里有很好的例子,可以帮助您理解。
