Online URL Encoder

I am making a POST call from Angular to .Net WebAPI which works on most cases but causing problem when passing a request parameter which contains a '+' sign as a trailing character.In .Net WebAPI Service which used Newtonsoft.Json for serialization, when receives request object that missing '+' at the end of the request.

My Angular Code :

const body = new HttpParams().set('UserID', 'James').set('Password', 'Bond+');
this.http.post(API_URLS.UserAuthentication, body.toString(),{ headers: new HttpHeaders().set('Content-Type', 'application/x-www-form-urlencoded') }

Seems to me it's not problem with Angular or .Net , but I may be missing something here.

I'm trying to send encrypted data over the url to another site (using file_get_contents("anotherUrl.php?hash=$encryptedString"). The problem is, sometimes, the encryption contains some special characters, like +, and this causes the decryption to fail.

Here are my encryption / decryption methods:

public function encrypt($string, $key){    return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $string, MCRYPT_MODE_CBC, md5(md5($key))));}public function decrypt($encrypted, $key){    return rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode($encrypted), MCRYPT_MODE_CBC, md5(md5($key))), "\0");}

Here's an example encrypted string which contains a +, and I'm guessing that this causes the decryption to fail.

Any ideas how I should solve this? I've tried to do urlencode() and urldecode() on the hash, however that also seems to cause the encryption to break. Is there a way to change the encryption algorithm to get it to only return url safe characters?

I am testing a HTTP Post request with an URL like following:

https://myurl.com/api/logs/%2Fvar%2Flog%2Fmessages?Api-Token=12332429nmdsafs

I have URL encoding disabled and here my post request:

RestAssured.given().contentType(JSON).log().all().urlEncodingEnabled(false).baseUri(RestAssured.baseURI).basePath(url).pathParam(LOG_PATH_PARAM_NAME, urlEncodeString(requireNonNull(logPath))).body(myJsonBody).when().post("/logs/{logPath}").then().statusCode(OK.getStatusCode());

I also tried it like this:

RestAssured.given().contentType(JSON).log().all().urlEncodingEnabled(false).baseUri(RestAssured.baseURI).basePath(url).body(myJsonBody).when().post("/logs/" + urlEncodeString(requireNonNull(logPath))).then().statusCode(OK.getStatusCode());

And here the urlEncodeString method:

private static String urlEncodeString(String value) throws UnsupportedEncodingException {        return URLEncoder.encode(value, StandardCharsets.UTF_8.name()).replaceAll("\\+", "%20");    }

The problem now is that my URL mentioned above gets encoded to following:

https://myurl.com/api/logs/var/log/messages?Api-Token=12332429nmdsafs

Does anyone know what is wrong here? Or knows a workaround?I already tried to double escape the path.

EDIT:

I just found out that disabling URL encoding only works for the URL parameters.

Why am I getting this error when trying to urlencode this string

 >>> callback = "http://localhost/application/authtwitter?twitterCallback" >>> urllib.urlencode(callback) Traceback (most recent call last):      File "<stdin>", line 1, in <module>      File "/usr/lib/python2.7/urllib.py", line 1261, in urlencode      raise TypeError TypeError: not a valid non-string sequence or mapping object

How to sent POST request with content-type = application/x-www-form-urlencoded.Given an access code, I am trying to get the AccessToken using POST request where I have all the information set in POST URL so i don't know what to pass as Http content in the postAysnc method.

According to another post For application/x-www-form-urlencoded, the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be:

MyVariableOne=ValueOne&MyVariableTwo=ValueTwo.

So I have similar case where my POST url has all the information as querystring, in that case I don't know what to pass as HttpContent in the postAysnc method since its a mandatory parameter

HttpClient client = new HttpClient();StringContent queryString = new StringContent(data);HttpResponseMessage response = await client.PostAsync(new Uri(url), queryString );
