escaping

I'm using angularjs' $http service to post data to my API. It works great.. until I add and equals sign to the contents of data (JSONRequest in example) var request = { 'method': 'POST', 'url': API_URL + apiActionName, 'data': JSONRequest, 'withCredentials': true, }; $http(request). success(function(data, status, headers, config) { // handle success }). error(function(data, status, headers, config) { // handle error } this works for data contain the following JSONRequest { 'text':'this is some text' } however when the data contains this { 'text':'this is = some text' } the request is escaped

I want to execute powershell command and put it in batch variable The command: for /f "delims=" %%i in ('powershell ^(Get-ChildItem ""\dir\"" -Name | sort-object {\[regex\]::Replace^($_,^'\d+^',{$args\[0\].Value.PadLeft^(20^)}^)} | select -last 1^) ') do set output=%%i It can't be executed due special character. In addition, I can't pause the window so it closes before I can see what is the problem. I think the problem is with the pipe "|", because the following command does work(the part before the pipe) for /f "delims=" %%i in ('powershell ^(Get-ChildItem ""\dir\"" -Name^) ') do set output=%

I have a function in Postgres: CREATE OR REPLACE FUNCTION upsert(sql_insert text, sql_update text) RETURNS integer AS $BODY$ BEGIN EXECUTE sql_insert; RETURN 1; EXCEPTION WHEN unique_violation THEN EXECUTE sql_update; RETURN 2; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 100; ALTER FUNCTION upsert(text, text) OWNER TO dce; I usually use this query to call that function: select upsert( $$INSERT INTO zz(a, b) VALUES (66, 'hahahaha')$$, $$UPDATE zz SET a=66, b='hahahaha' WHERE a=66$$ ) It works. Unfortunately, my query string cannot contain $$ , like this: select upsert( $$INSERT INTO zz(a, b)

After I created my own json encoder, I realized it was replacing double-quotes with two escaping backslashes instead of one. I realize, now, that C# has a built in Json.Encode() method, and yes, I have gotten it to work, however, I am left baffled by why the following code (the json encoder I had built) didn't replace quotes as I would expect. Here is my json encoder method: public static string jsonEncode(string val) { val = val.Replace("\r\n", " ") .Replace("\r", " ") .Replace("\n", " ") .Replace("\"", "\\\"") .Replace("\\", "\\\\"); return val; } The replace call: Replace("\"", "\\\"") is

I need to make several queries to LDAP directory server and I'm using JNDI directory facilities for it. Then I need to do some work with the objects from the query result using their distinguished names. Some of the entries returned by the server contain forward slash character, and because of this JNDI escapes the whole name with double quotes: NamingEnumeration<SearchResult> results = dirContext.search(queryRoot, queryFilter, controls); for (SearchResult result : Collections.list(results)) { String objectName = result.getName(); System.out.println(objectName); } If one of the objects in the

In my bash script, i am trying to execute following Linux command: sed -i "/$data_line/ d" $data_dir $data_line is entered by user and it may conatain special characters that could brake regex. How can i escape all of the possible special characters in $data_line before i execute sed command? You might be able to use this technique to protect the selector. The lines marked with " ***** " below are the significant lines. The others are mostly for testing and demonstration. The key is to use a character that doesn't appear in the user input to delimit the selector address. data_line='.*/ s/GOLD

I'm quite new to Bash so this might be something trivial, but I'm just not getting it. I'm trying to escape the spaces inside filenames. Have a look. Note that this is a 'working example' - I get that interleaving files with blank pages might be accomplished easier, but I'm here about the space. #! /bin/sh first=true i=combined.pdf o=combined2.pdf for f in test/*.pdf do if $first; then first=false ifile=\"$f\" else ifile=$i\ \"$f\" fi pdftk $ifile blank.pdf cat output $o t=$i i=$o o=$t break done Say I have a file called my file.pdf (with a space). I want the ifile variable to contain the

How do I correctly serialize and unserialize a string containing escaped characters? Given: $data = "\'test\'"; $out= serialize($data); print_r($out); // -> s:8:"\'test\'"; The problem here is, that the string length is not accepted by unserialize: $out = 's:8:"\'test\'"'; var_dump(unserialize($out)); // -> bool(false) But if I change the string length to 6 (ignoring the escape chars): $out = 's:6:"\'test\'"'; var_dump(unserialize($out)); // -> string(6) "'test'" It unserializes correctly. What would be a good way of handling this problem? Your test cases don't match, you're wrapping the

php function preg_quote escapes these characters . \ + * ? [ ^ ] $ ( ) { } = ! < > | : - Could you please suggest what I could use to escape these characters: + - && || ! ( ) { } [ ] ^ " ~ * ? : / Edited (as requested by "on hold"): I'm implementing a Solr search and it says: Solr gives the following characters special meaning when they appear in a query: + - && || ! ( ) { } [ ] ^ " ~ * ? : / To make Solr interpret any of these characters literally, rather as a special character, precede the character with a backslash character . This may help you: <?php $subject = "+ - && || ! ( ) { } [ ] ^ \
