【问题描述】：
帮助这个特定的服务器端 php 代码我没有任何 php 知识，我必须将三个图像从 android 上传到这个 php 页面。
我尝试了很多方法并进行了搜索，但没有教程或任何内容对我没有帮助，我的 android 代码运行正常。 DNS 也已配置，但图像未显示在服务器端。请帮我写java代码。
PHP：
<?php
if ($_FILES["file1"]["error"] > 0)
{
header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else if ($_FILES["file2"]["error"] > 0)
{
header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else if ($_FILES["file3"]["error"] > 0)
{
header("HTTP/1.1 400 Bad Request");
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else
{
if ($_FILES["file1"]["error"] > 0)
{
echo "Error: " . $_FILES["file1"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file1"]["name"] . "<br />";
echo "Type: " . $_FILES["file1"]["type"] . "<br />";
echo "Size: " . ($_FILES["file1"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file1"]["tmp_name"]. "<br />";
}
//$target_path = "uploads/";
$target_path = "elp/pendingimages/";
$target_path = $target_path . basename( $_FILES['file1']['name']);
if(move_uploaded_file($_FILES['file1']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['file1']['name']).
" has been uploaded";
}
else{
echo "There was an error uploading the file, please try again!";
}
if ($_FILES["file2"]["error"] > 0)
{
echo "Error: " . $_FILES["file2"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file2"]["name"] . "<br />";
echo "Type: " . $_FILES["file2"]["type"] . "<br />";
echo "Size: " . ($_FILES["file2"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file2"]["tmp_name"]. "<br />";
}
//$target_path = "uploads/";
$target_path = "elp/pendingimages/";
$target_path = $target_path . basename( $_FILES['file2']['name']);

【问题讨论】：
-
那些图片必须通过HTTP上传，你如何上传？ （既然你提到了Java）
-
我的意思是android应用程序中需要的java Activity代码。而且我也厌倦了使用 http 和 mulitpart 上传，但没有用。这可能是因为我试图在不了解 php 的情况下编写代码。
-
@user1160020，php 代码是正确的。所以，不要责怪你的php知识。您的多部分请求中似乎存在错误。
-
我也尝试过使用 multipart 但目前我正在使用此代码并且代码中没有错误，否则：S
-
@user1160020 你的问题解决了吗？你能告诉我解决方案吗？你的代码看起来和我的一模一样。
