Htaccess以某种方式自动地在URL的末尾删除所有尾部斜杠并且只保留一个.
例如,http:// localhost/api/param1 ///成为http:// localhost/api/param1 /
你能否告诉我为什么会发生这种情况以及如何摆脱这种情况?(.*)应该匹配一切吗?但事实并非如此.就像我说的,如果我去的http://本地主机/ API /参数1 ///的$_GET['url']应该是param1///,但它是param1/.
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
Run Code Online (Sandbox Code Playgroud) 我正在尝试写入外部辅助存储(sd 卡),但看起来我没有权限。
根据安卓:
“辅助外部存储不得由应用程序写入,除非在合成权限允许的特定于包的目录中。 ”
所以这行不通:
try {
String sdCard = System.getenv("SECONDARY_STORAGE");
FileWriter writer = new FileWriter(new File(sdCard, "test.txt"));
writer.write("a test");
writer.flush();
writer.close();
} catch (IOException e) {
Log.d(e.toString());
//java.io.FileNotFoundException: /storage/extSdCard/test.txt: open failed: EACCES (Permission denied)
}

我在 AndroidManifest.xml 中有权限 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
并且Environment.getExternalStorageDirectory()无法工作,因为我试图写入可移动 SD 卡而不是手机内存。
那么,如果应用程序应该被禁止写入二级存储,那么文件管理器之类的应用程序如何写入 SD 卡呢?
没有问号占位符的预备声明仍然安全吗?
例:
String username = "userename from EditText";
String password = "password from EditText";
PreparedStatement statement = _con.prepareStatement("SELECT * FROM users WHERE username = '"+username+"' AND password = '"+password+"';");
ResultSet rs = statement.executeQuery();

我想做的事:
$source = file_get_contents("encryptedPhpFile.php");
$source = decrypt($source, "mySecretKey");
//$source now contains decrypted source code which needs to be included
//I cant use eval($source); because that code also contains
//html/css/opening and closing php tags ... which eval() does
//not know how to render
//I cant write the source into temporary file and then include
//that file because as soon as I write decrypted source to a disk,
//it is exposed and it can be copyed
