java - 文件未上传到 Android 服务器上

Question

我尝试了多种在服务器上加载图像的方法，但没有一种方法显示任何错误。但没有任何帮助我。图片没有上传到服务器。图像的文件路径正确。我还尝试更改服务器上的文件路径，它也没有帮助我并添加了访问文件的权限，这没有帮助。

加载文件:

public class UploadFiles {
    private String sourceFileUri = "";

    public UploadFiles(final String sourceFileUri){
        this.sourceFileUri = sourceFileUri;
        new UploadFileAsync().execute("");
    }

    private class UploadFileAsync extends AsyncTask<String, Void, String> {

        @Override
        protected String doInBackground(String... params) {
            try {
                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()) {

                    try {
                        String upLoadServerUri = "http://myserver/gpstracker/api/v1/users/uploadfile.php";

                        // open a URL connection to the Servlet

                        URL url = new URL(upLoadServerUri);

                        // Open a HTTP connection to the URL
                        conn = (HttpURLConnection) url.openConnection();

php文件

<?php

 if (is_uploaded_file($_FILES['bill']['tmp_name'])) {
    $uploads_dir = '/var/www/html/gpstracker/api/v1/users/images';
    $tmp_name = $_FILES['bill']['tmp_name'];
    $pic_name = $_FILES['bill']['name'];
    move_uploaded_file($tmp_name, $uploads_dir.$pic_name);
  }
    else{
     echo "File not uploaded successfully.";
  }  
?>

服务器响应:

System.out: SERVER: OK

服务器回复200并不代表上传成功。尝试输出 php echo。请参阅Get PHP Echo in Android .
