将图像上载到PHP Android服务器
我现在无法将图像上载到我的服务器。我可以在安卓设备上拍照并获取我的位置。我有以下代码将文件上载到服务器:将图像上载到PHP Android服务器,php,android,Php,Android,我现在无法将图像上载到我的服务器。我可以在安卓设备上拍照并获取我的位置。我有以下代码将文件上载到服务器: public Boolean postFunction(File image) { String tag = "postFunction"; HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(UPLOAD_URL); try {
public Boolean postFunction(File image) {
String tag = "postFunction";
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(UPLOAD_URL);
try {
MultipartEntity entity = new MultipartEntity();
entity.addPart("type", new StringBody("photo"));
entity.addPart("data", new FileBody(image));
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
Log.i(tag, "picture was uploaded " + response.toString());
return true;
} catch (ClientProtocolException e) {
Log.e(tag, "Client: " + e.toString());
return false;
} catch (IOException e) {
Log.e(tag, "IO: " + e.toString());
return false;
}
}
我将图像文件传递给这个函数,它执行上载。然而,我认为错误在于服务器端
以下是我的PHP代码:
public function upload() {
//$type = $this->input->post('type');
//$data = $this->input->post('data');
$base = $_REQUEST['data'];
echo $base;
// base64 encoded utf-8 string
$binary = base64_decode($base);
// binary, utf-8 bytes
header('Content-Type: bitmap; charset=utf-8');
// print($binary);
//$theFile = base64_decode($image_data);
$file = fopen('./test.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo '<img src=test.jpg>';
}
公共函数上传(){
//$type=$this->input->post('type');
//$data=$this->input->post('data');
$base=$_请求['data'];
echo$base;
//base64编码utf-8字符串
$binary=base64_解码($base);
//二进制,utf-8字节
标题('Content-Type:bitmap;charset=utf-8');
//打印(二进制);
//$theFile=base64\u解码($image\u数据);
$file=fopen('./test.jpg',wb');
fwrite($file,$binary);
fclose($文件);
回声';
}
文件被触摸,但仍然保持空白。我是不是遗漏了什么?请帮忙,我试着用谷歌搜索了一下,但得到了不同的结果,对我帮助不大。你可以查看一个非常好的教程 还可以尝试以下代码

如果您在基于unix的平台上运行apache/php,请确保您的apache服务器对其试图存储文件的目录具有写入权限(根据您当前的代码,php脚本所在的目录)。作为快速测试,请在脚本所在的目录中执行chmod 0777.
