[英]Uploading a small sized image to server using php and android
在PHP方面,我正在使用以下代碼
$val = (isset($_GET['file']) ? $_GET['file'] : null);
$isUploaded = false;
return $val;
if($val != null)
{
if (move_uploaded_file(@$_FILES['file']['tmp_name'], $mainPath))
{
$isUploaded = true;
}
}
我正在使用的Android端
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("file", Base64Coder.encodeLines(imageArray)));
HttpResponse response = null;
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter("http.connection-manager.timeout", 15000);
try {
HttpPost httppost = new HttpPost(url);
httppost.setEntity(entity);
response = httpclient.execute(httppost);
然而
$val = (isset($_GET['file']) ? $_GET['file'] : null);
返回null
如何正確上傳圖片
這是我要上傳的代碼,可以正常工作。 您需要導入httpmime jar
PHP代碼
$uploads_dir = '/Library/WebServer/Documents/Upload/upload/'.$_FILES['userfile']['name'];
if(is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo $_POST["contentString"]."\n";
echo "File path = ".$uploads_dir;
move_uploaded_file ($_FILES['userfile'] ['tmp_name'], $uploads_dir);
} else {
echo "\n Upload Error";
echo "filename '". $_FILES['userfile']['tmp_name'] . "'.";
print_r($_FILES);
JAVA代碼
HttpClient client = new DefaultHttpClient();
HttpPost postMethod = new HttpPost("http://localhost/Upload/index.php");
File file = new File(filePath);
MultipartEntity entity = new MultipartEntity();
FileBody contentFile = new FileBody(file);
entity.addPart("userfile",contentFile);
StringBody contentString = new StringBody("This is contentString");
entity.addPart("contentString",contentString);
postMethod.setEntity(entity);
HttpResponse response = client.execute(postMethod);
HttpEntity httpEntity = response.getEntity();
String state = EntityUtils.toString(httpEntity);
$val = (isset($_GET['file']) ? $_GET['file'] : null);
用。。。來代替
$val = (isset($_FILES['file']['name']) ? $_FILES['file']['name'] : null);
在手冊中查看有關后期方法上傳的可用字段。 http://www.php.net/manual/en/features.file-upload.post-method.php
