php - 如果(setChunkedStreamingMode)无法将文件从android发送到php

Question

试图将大文件从 android 发送到 php，我可以发送小尺寸(最多 1 mp)我四处寻找解决方案，出现了“setChunkedStreamingMode”当我设置 connection.setconnection(1024) 时，我无法发送任何文件，即使是小文件。获取 PHP 回显“无法上传文件!!!”这是安卓代码

public static void main(String[] args) throws IOException, URISyntaxException {

这是PHP代码

<?php
$target_path = "uploads/";
/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path)) {
    echo "The first file ".  basename( $_FILES['uploaded_file']['name']).
    " uploaded.";
} else{
    echo "cannot uploading the file!!!!  ";
    echo "filename: " .  basename( $_FILES['uploaded_file']['name']);
    echo "target_path: " .$target_path;
}
?>

有什么帮助吗？谢谢

**使用此 PHP 代码，它对我来说工作正常 **

public void uploadFile() {
String charset = "UTF-8";
File[] uploadFileArray = new File[mediaList.size()];

for (int i = 0; i < mediaList.size(); i++) {
    uploadFileArray[i] = new File(mediaList.get(i).getMediaPath());
}

try {
    MultipartUtility multipart = new MultipartUtility(upLoadServerUri, charset);

    for (int i = 0; i < mediaList.size(); i++) {
        if (isImage)) {
            multipart.addFilePart("image_doc[]", uploadFileArray[i]);
        } 
        else if (isVideo) {
            multipart.addFilePart("video_doc[]", uploadFileArray[i]);
        } 
        else if (isAudio) {
            multipart.addFilePart("audio_doc[]", uploadFileArray[i]);
        }
    }

    List<String> responseUploadDocument = multipart.finish();
    System.out.println("SERVER REPLIED:");

    for (String line : responseUploadDocument) {
        System.out.println(line);
        responseUploadDocumentString = line;
    }

    if (responseUploadDocumentString != null) {
        JSONObject jsonObj = new JSONObject(responseUploadDocumentString);
        statusUploadDoc = jsonObj.getString("status");
    }

} catch (Exception e) {
    e.printStackTrace();
}
