android服务器php上传

服务端:(auth变量为用户登录状态验证,这部分确认没错。)

if( $auth==1){    $target_path = ROOT.basename($_FILES['uploadedfile']['name']);    echo $target_path;    if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {        echo "The file ".  basename( $_FILES['uploaded_file']['name']). " has been uploaded";     } else{        echo "There was an error uploading the file, please try again!" . $_FILES['uploadedfile']['error'];    } }else{    echo 'error_login';}

客户端:

private String uploadFile = Environment.getExternalStorageDirectory()+ "/" + packageName + "/" + "images" + "/" + "image.jpg";private String srcPath = Environment.getExternalStorageDirectory()+ "/" + packageName + "/" + "images" + "/" + "image.jpg";private String actionUrl = getTargetUrl(); //PHP连接 private void uploadFile(final String uploadUrl) {        Thread thread = new Thread() {            @Override            public void run() {                //DEBUG                File file = new File(uploadFile);                if(file.exists()){                    Log.i("DEBUG","要上传的文件存在");                }                String end = "\r\n";                String twoHyphens = "--";                String boundary = "******";                try {                    URL url = new URL(uploadUrl);                    HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();                    // 设置每次传输的流大小,可以有效防止手机因为内存不足崩溃                    // 此方法用于在预先不知道内容长度时启用没有进行内部缓冲的 HTTP 请求正文的流。                    httpURLConnection.setChunkedStreamingMode(128 * 1024);// 128K                    // 允许输入
输出流 httpURLConnection.setDoInput(true); httpURLConnection.setDoOutput(true); httpURLConnection.setUseCaches(false); // 使用POST方法 httpURLConnection.setRequestMethod("POST"); httpURLConnection.setRequestProperty("Connection", "Keep-Alive"); httpURLConnection.setRequestProperty("Charset", "UTF-8"); httpURLConnection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); DataOutputStream dos = new DataOutputStream(httpURLConnection.getOutputStream()); dos.writeBytes(twoHyphens + boundary + end); dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"" + srcPath.substring(srcPath.lastIndexOf("/") + 1) + "\"" + end); dos.writeBytes(end); FileInputStream fis = new FileInputStream(srcPath); byte[] buffer = new byte[8192]; // 8k int count = 0; // 读取文件 while ((count = fis.read(buffer)) != -1) { dos.write(buffer, 0, count); } fis.close(); dos.writeBytes(end); dos.writeBytes(twoHyphens + boundary + twoHyphens + end); dos.flush(); InputStream is = httpURLConnection.getInputStream(); InputStreamReader isr = new InputStreamReader(is, "utf-8"); BufferedReader br = new BufferedReader(isr); String result = br.readLine(); dos.close(); is.close(); } catch (Exception e) { e.printStackTrace(); setTitle(e.getMessage()); } } }; thread.start(); }

运行后返回错误:(包含服务端接收页面的链接)
报错后运行也中止了,没有收到服务端打印的任何信息。
java.io.FileNotFoundException: http://.../upload.php
at com.android.okhttp.internal.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:206)
Studio指示错误的行是:
InputStream is = httpURLConnection.getInputStream();

起初以为是本地文件不存在,结果用文件管理器确认、包括代码中检查后也打出了“文件存在“,可以确定的是客户端文件路径没错。后来以为URL链接有问题,用电脑浏览器可以正常打开,可以打印内容,所以服务端链接也应没错。

百思不得其解,搜索很久也没找到解决方案,特来求助。求老司机带一带。
