php - Android - 通过 PHP 脚本上传图片

Question

我正在尝试将存储在手机上的图像上传到 linux 目录中。代码似乎运行没有错误，异常也没有发现任何问题，但是图像没有上传。发送回 HTTP 200 ok 响应。通过 logcat 查看显示的唯一警告是:

Failure getting entry for 0x01080c1 (t=7 e=705) in package 0 (error -75)

我已经确定我已经在 android list 中使用了 internet 权限声明并且我已经将目标文件夹权限设置为 777，我是否遗漏了什么？

这是android函数:

public int uploadFile(String sourceFileUri) {


    String fileName = sourceFileUri;

    HttpURLConnection conn = null;
    DataOutputStream dos = null;
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1 * 1024 * 1024;
    File sourceFile = new File(sourceFileUri);

    if (!sourceFile.isFile()) {

        dialog.dismiss();

        Log.e("uploadFile", "Source File not exist :"
                +uploadFilePath + "" + uploadFileName);

        runOnUiThread(new Runnable() {
            public void run() {
                messageText.setText("Source File not exist :"
                        +uploadFilePath + "" + uploadFileName);
            }
        });

        return 0;

    }
    else
    {
        try {

            // open a URL connection to the Servlet
            FileInputStream fileInputStream = new FileInputStream(sourceFile);
            URL url = new URL(upLoadServerUri);

            if(serverResponseCode == 200){

                runOnUiThread(new Runnable() {
                    public void run() {

                        String msg = "File Upload Completed.\n\n See uploaded file here : \n\n"

            //close the streams //

            dos.flush();

        }
        dialog.dismiss();
        return serverResponseCode;

    }

这是PHP脚本

<?php

$file_path = "/var/www/images/";

$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);

if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
    echo "success";
} else{
    echo "fail";
}
?>

试试这个可能对您有帮助

            HttpURLConnection mHttpURLConnection = null;
            DataOutputStream mOutputStream = null;
            String strLineEnd = "\r\n";
            String strTwoHyphens = "--";
            strUpLoadServerUri = UploadServerPath;
            String strBoundary = "*****";
            int bytesRead, bytesAvailable, bufferSize;
            byte[] buffer;
            int maxBufferSize = 1 * 1024 * 1024;
            File sourceFile = new File(strUploadFiles);

            if (sourceFile.isFile()) {

                try {

                    // open a URL connection to the Servlet
                    FileInputStream fileInputStream = new FileInputStream(sourceFile);
                    URL url = new URL(strUpLoadServerUri);

                    // Open a HTTP connection to the URL

                    mHttpURLConnection = (HttpURLConnection) url
                            .openConnection();
                    mHttpURLConnection.setDoInput(true); // Allow Inputs
                    mHttpURLConnection.setDoOutput(true); // Allow Outputs
                    mHttpURLConnection.setUseCaches(false); // Don't use a Cached Copy

                    mHttpURLConnection.setRequestMethod("POST");
                    mHttpURLConnection.setRequestProperty("Connection","Keep-Alive");
                    mHttpURLConnection.setRequestProperty("ENCTYPE","multipart/form-data");

                    mHttpURLConnection.setRequestProperty("uploaded_file",strUploadFiles);

                    mOutputStream = new DataOutputStream(mHttpURLConnection.getOutputStream());

                    mOutputStream.writeBytes(strTwoHyphens + strBoundary + strLineEnd);
                    mOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename="+ strUploadFiles + strLineEnd);

                    mOutputStream.writeBytes(strLineEnd);

                    // create a buffer of maximum size
                    bytesAvailable = fileInputStream.available();

                    bufferSize = Math.min(bytesAvailable, maxBufferSize);
                    buffer = new byte[bufferSize];

                    // read file and write it into form...
                    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                    while (bytesRead > 0) {

                        mOutputStream.write(buffer, 0, bufferSize);
                        bytesAvailable = fileInputStream.available();
                        bufferSize = Math.min(bytesAvailable, maxBufferSize);
                        bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                    }

                    // send multipart form data necesssary after file data...
                    mOutputStream.writeBytes(strLineEnd);
                    mOutputStream.writeBytes(strTwoHyphens + strBoundary + strTwoHyphens + strLineEnd);

                    // Responses from the server (code and message)
                    serverResponseCode = mHttpURLConnection.getResponseCode();

                    // close the streams //
                    fileInputStream.close();
                    mOutputStream.flush();
                    mOutputStream.close();

                } catch (MalformedURLException ex) {
                    ex.printStackTrace();
                    Log.e("Upload file to server", "error: " + ex.getMessage(),ex);
                } catch (Exception e) {
                    e.printStackTrace();
                    Log.e("Upload file to server Exception","Exception : " + e.getMessage(), e);
                }
            }

            if (serverResponseCode == 200) {

                Log.d("File Uploaded For ",strUploadFiles + "   Successful");
            }
            else{
                Log.d("File Uploaded For ",strUploadFiles + "   Failed");
            }

听到 strUploadFiles 是你的文件路径

您的服务器端代码

<?php
        $Dir = "C:/Path/";

    if(!is_dir($Dir)) 
    {
        mkdir($Dir, 0777);
        chmod($Dir, 0777);
    }


    $file_path = $Dir.basename( $_FILES['uploaded_file']['name']);

 ?>
