如何使用php web服务将图像从android上传到mongodb

我正在从android上拍摄照片，并通过PHP web服务发送

我正在使用以下代码：-

<?php
//creating mongodb database connection
$m = new MongoClient();
$db = $m->companydb;
$grid= $db->getGridFS('myGrid');
//creating for request
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $pic = $_POST['image'];
    //uploading in mongodb database
    // we are getting error in this line -->This function work properly when              

    we are taking image from html file and use this command
    //storeUpload('image'); but in this file first we are string in a variable         
    and then passing this variable using storeUpload function 
    // maybe thats why we are geeting this issue
    $grid->storeUpload($pic);
    echo "Successfully Uploaded";
} 
else{
    echo "please check the REQUEST_METHOD"; 
}
?>

谁能告诉我如何上传它。

试着用它来发布到PHP。并且，您将要发布到PHP的内容是一个编码的。这是一种将图像发送到数据库并将其存储为字符串的简单方法。（使用~1.2x时，文件大小将更大）
