Wiremock match request POST by params - post

Question

I have a simple POST request sending params using application/x-www-form-urlencoded encoding.
Looking in the wiremock docs I can't find a way to match the request by the params values, something like the querystring match I mean.
Furthermore it seems also impossible to contains for the body, nor to match the entire body in clear (just as base64).
Is there a way to match this kind of requests?

Answer 1

Another option that I found was to use contains for Stubbing Content-Type: application/x-www-form-urlencoded
{
"request": {
"method": "POST",
"url": "/oauth/token",
"basicAuthCredentials": {
...
},
"bodyPatterns": [
{
"contains": "username=someuser"
}
]
},
"response": {
....
}
}

With classic wiremock you can use bodyPatterns' matchers and regular expressions:
for example:
...
"request": {
"method": "POST",
"url": "/api/v1/auth/login",
"bodyPatterns": [
{
"matches": "(.*&|^)username=test($|&.*)"
},
{
"matches": "(.*&|^)password=123($|&.*)"
}
]
},

I had a similar problem - I wanted to check the exact parameters , but without patterm magic (so easier to maintain). As a workaround, I created a helper class :
import java.util.Iterator;
import java.util.LinkedHashMap;
public class WireMockUtil {
public static String toFormUrlEncoded(LinkedHashMap<String, String> map) {
if (map == null) {
return "";
}
StringBuilder sb = new StringBuilder();
Iterator<String> it = map.keySet().iterator();
while (it.hasNext()) {
String key = it.next();
String value = map.get(key);
appendFormUrlEncoded(key,value,sb);
if (it.hasNext()) {
sb.append('&');
}
}
return sb.toString();
}
public static String toFormUrlEncoded(String key, String value) {
StringBuilder sb = new StringBuilder();
appendFormUrlEncoded(key, value,sb);
return sb.toString();
}
public static void appendFormUrlEncoded(String key, String value, StringBuilder sb) {
sb.append(key).append('=');
if (value != null) {
sb.append(value);
}
}
}
Inside the Wiremock test you can use it via:
LinkedHashMap<String, String> map = new LinkedHashMap<>();
map.put("key1", "value1");
map.put("key2", "value2");
...
withRequestBody(equalTo(WireMockUtil.toFormUrlEncoded(map))).
Or check only dedicated parts by containing:
withRequestBody(containing(WireMockUtil.toFormUrlEncoded("key","value1"))).

You could try https://github.com/WireMock-Net/WireMock.Net
Matching query parameters and body can be done with this example json:
{
"Guid": "dae02a0d-8a33-46ed-aab0-afbecc8643e3",
"Request": {
"Url": "/testabc",
"Methods": [
"put"
],
"Params": [
{
"Name": "start",
"Values": [ "1000", "1001" ]
},
{
"Name": "end",
"Values": [ "42" ]
}
],
"Body": {
"Matcher": {
"Name": "WildcardMatcher",
"Pattern": "test*test"
}
}
}
}
