文件上传HttpClient - 所选文件夹中没有文件

Question

我使用loopj / android-async-http lib在我的服务器上传文件。

我的Android代码：

File myFile = new File(getRealPathFromURI(SettintsActiviy.this, selectedImage));

RequestParams params = new RequestParams();
try {
    params.put("uploaded_file", myFile);
    params.put("name", "adfadfa");
    params.put("tmp_name", "fadfadfa");
} catch (FileNotFoundException e) {
    e.printStackTrace();
}

AsyncHttpClient client = new AsyncHttpClient();
client.post("http://localhost:8081/html/upload.php", params, new AsyncHttpResponseHandler() {

    @Override
    public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
        System.out.println("statusCode "+statusCode);//statusCode 200
    }

    @Override
    public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {

    }
});

我的upload.php

<?php

$file_path = "/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";
}?>

记录Android结果：
