任何人都可以有示例/示例代码，用于通过我的 android 应用程序从 android 上传视频并将该视频存储在服务器端。

这是另一个例子。非常相似，但最大的区别是这是一个数据类，旨在允许其他 post 变量也使用它。例如，您有一个针对不同用户和组的特定文件存储。然后，您希望将该数据与视频一起发送。这个数据类实际上可以用于您网站的所有帖子。所以数据类是
public class MultiPartData {
final String requestURL = "http://www.yoursite.com/some.php";
final String charset="UTF-8";
final String boundary="*******";
private static final String LINE_FEED = "\r\n";
private HttpURLConnection httpConn;
private DataOutputStream outputStream;
private PrintWriter writer;
//establishes connection
public MultiPartData() throws IOException {
URL url = new URL(requestURL);
httpConn = (HttpURLConnection) url.openConnection();
httpConn.setUseCaches(false);
httpConn.setChunkedStreamingMode(4096);
httpConn.setDoOutput(true); // indicates POST method
httpConn.setDoInput(true);
httpConn.setRequestMethod("POST");
httpConn.setRequestProperty("ENCTYPE", "multipart/form-data");
httpConn.setRequestProperty("Content-Type",
"multipart/form-data; boundary=\"" + boundary + "\"");
httpConn.setRequestProperty("Connection", "Keep-Alive");
outputStream = new DataOutputStream(httpConn.getOutputStream());
writer = new PrintWriter(new OutputStreamWriter(outputStream, charset),true);
}
//adds post variables to the header body
public void addFormField(String name, String value) {
writer.append("--" + boundary).append(LINE_FEED);
writer.append("Content-Disposition: form-data; name=\"").append(name).append("\"")
.append(LINE_FEED);
writer.append("Content-Type: text/plain; charset=" + charset).append(
LINE_FEED);
writer.append(LINE_FEED);
writer.append(value).append(LINE_FEED);
writer.flush();
}
//adds files to header body can be anytype of files
public void addFilePart(String fieldName, String filePath) throws IOException {
File uploadFile=new File(filePath);
String fileName = uploadFile.getName();
writer.append("--" + boundary).append(LINE_FEED);
writer.append("Content-Disposition:form-data; name=\"")
.append(fieldName).append("\"; filename=\"")
.append(fileName).append("\"")
.append(LINE_FEED);
writer.append("Content-Type: ").append(URLConnection.guessContentTypeFromName(fileName))
.append(LINE_FEED);
writer.append("Content-Transfer-Encoding: binary").append(LINE_FEED);
writer.append(LINE_FEED);
writer.flush();
FileInputStream inputStream = new FileInputStream(uploadFile);
int maxBufferSize=2*1024*1024;
int bufferSize;
int bytesAvailable=inputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[] buffer = new byte[bufferSize];
int bytesRead=inputStream.read(buffer);
do {
outputStream.write(buffer, 0, bytesRead);
bytesAvailable = inputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = inputStream.read(buffer, 0, bufferSize);
}while (bytesRead >0);
outputStream.flush();
inputStream.close();
writer.append(LINE_FEED);
writer.flush();
}
//adds header values to body
public void addHeaderField(String name, String value) {
writer.append(name).append(": ").append(value).append(LINE_FEED);
writer.flush();
}
//closing options you must use one of the options to close the connection
// finishString() gets results as a string
// finnishJOBJECT() gets results as an JSONObject
// finnishJARRAY() gets results as an JSONArray
// finnishNoResponse() closes connection with out looking for response
public String finishString() throws IOException {
String response = "";
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
String line;
StringBuilder sb= new StringBuilder();
BufferedReader br = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), "UTF-8"));
while ((line=br.readLine()) != null) {
sb.append(line);
response =sb.toString();
}
br.close();
return response;
}
public JSONObject finnishJOBJECT() throws IOException, JSONException {
JSONObject response = null;
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
String line;
StringBuilder sb= new StringBuilder();
BufferedReader br = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), "UTF-8"));
while ((line=br.readLine()) != null) {
sb.append(line);
response =new JSONObject(sb.toString());
}
br.close();
return response;
}
public JSONArray finnishJARRAY()throws IOException, JSONException {
JSONArray response = null;
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
String line;
StringBuilder sb= new StringBuilder();
BufferedReader br = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), "UTF-8"));
while ((line=br.readLine()) != null) {
sb.append(line);
response =new JSONArray(sb.toString());
}
br.close();
return response;
}
public void finnishNoResponse(){
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
}
}
实现数据类的示例 AsyncTask 将是。
public void storeVideoBackground(String filePath,String identifier,String vType,String vName, storeImage serverPath){
progress.show();
new storeVideoAsyncTask(filePath,identifier,vType,vName,serverPath).execute();
}
public class storeVideoAsyncTask extends AsyncTask<Void,Void,String>{
String filePath; //path of the file to be uploaded
String vType; //variable used on server
String vName; //variable used on server
String identifier; //variable used on server
storeImage serverPath; //interface used to get my response
MultiPartData upload; //declares the data class for posting
public storeVideoAsyncTask(String filePath,String identifier,String vType,String vName, storeImage serverPath){
this.filePath=filePath;
this.vName=vName;
this.vType=vType;
this.identifier=identifier;
this.serverPath=serverPath;
}
@Override
protected String doInBackground(Void... params) {
JSONObject result;
String sPath="";
try {
upload=new MultiPartData();
upload.addHeaderField("User-Agent", "Android-User");
upload.addHeaderField("Test-Header","Header-Value");
upload.addFormField("appAuth",auth); //an auth string compared on server
upload.addFormField("action","storeVideo");//added post variable
upload.addFormField("vName",vName);//added post variable
upload.addFormField("identifier",identifier);//added post variable
upload.addFormField("vType",vType);//added post variable
upload.addFilePart("video",filePath);//added file video is the reference on server side to retrieve the file
sPath=upload.finishString();//returned server path to be used later
} catch (IOException e) {
e.printStackTrace();
}
return sPath;
}
@Override
protected void onPostExecute(String servPath) {
super.onPostExecute(servPath);
progress.dismiss();
serverPath.done(servPath);
}
}
现在我喜欢重用我的代码，所以这是另一个名为 ServerRequest 的类的一部分。我将上下文传递给它以进行进度对话框并声明其他值，例如我的 appAuth。
像这样检索文件。这是服务器端 php，您可以使用任何您喜欢的脚本与 post 变量进行交互。
if(isset($_FILES['video']['error'])){
$path = //path to store video
$file_name = $_FILES['video']['name'];
$file_size = $_FILES['video']['size'];
$file_type = $_FILES['video']['type'];
$temp_name = $_FILES['video']['tmp_name'];
if(move_uploaded_file($temp_name, $path.'/'.$file_name)){
$response =$path.'/'.$file_name;
}
}
后变量将被检索常用方法 $data=$_POST['data']; 如果此代码不适用于文件，那么它将是您服务器上某些东西的结果。可能是文件大小。大多数托管服务器对帖子大小上传文件大小等都有限制。有些服务器会让您在 .htaccess 中覆盖它。要调试问题，请在服务器端的 if(isset in 下添加回显以回显错误代码，并且 php 手册对它们的含义有很好的解释。如果它显示为 1，则尝试用 .htaccess 中的 php.ini 覆盖某些内容里面这样
php_value post_max_size 30M
php_value upload_max_filesize 30M
