## JSON (JsonMatcher)
Checks if a JSON object (or JSON as string) is DeepEqual.
#### C# option 1
```csharp
var server = WireMockServer.Start();
server
.Given(Request
.Create()
.WithPath("/jsonmatcher1")
.WithBody(new JsonMatcher("{ \"x\": 42, \"s\": \"s\" }"))
.UsingPost())
.WithGuid("debaf408-3b23-4c04-9d18-ef1c020e79f2")
.RespondWith(Response.Create().WithBody(@"{ ""result"": ""jsonbodytest1"" }"));
```
#### JSON Mapping option 1
``` js
{
"Guid": "debaf408-3b23-4c04-9d18-ef1c020e79f2",
"Request": {
"Path": {
"Matchers": [
{
"Name": "WildcardMatcher",
"Pattern": "/jsonmatcher1"
}
]
},
"Methods": [
"post"
],
"Body": {
"Matcher": {
"Name": "JsonMatcher",
"Pattern": "{ \"x\": 42, \"s\": \"s\" }"
}
}
},
"Response": {
"StatusCode": 200,
"Body": "{ \"result\": \"jsonbodytest\" }",
"UseTransformer": false
}
}
```
#### C# option 2
```csharp
var server = WireMockServer.Start();
server
.Given(Request
.Create()
.WithPath("/jsonmatcher2")
.WithBody(new JsonMatcher(new { x = 42, s = "s" }))
.UsingPost())
.WithGuid("debaf408-3b23-4c04-9d18-ef1c020e79f2")
.RespondWith(Response.Create().WithBody(@"{ ""result"": ""jsonbodytest2"" }"));
```
#### JSON Mapping option 2
``` js
{
"Guid": "debaf408-3b23-4c04-9d18-ef1c020e79f2",
"Request": {
"Path": {
"Matchers": [
{
"Name": "WildcardMatcher",
"Pattern": "/jsonmatcher2"
}
]
},
"Methods": [
"post"
],
"Body": {
"Matcher": {
"Name": "JsonMatcher",
"Pattern": { "x": 42, "s": "s" }
}
}
},
"Response": {
"StatusCode": 200,
"Body": "{ \"result\": \"jsonbodytest2\" }",
"UseTransformer": false
}
}
```
```
// matching
{ "x": 42, "s": "s" }
// not matching
{ "x": 42, "s": "?" }
```
#### C# option 3
It's also possible to use set `IgnoreCase` to true, this means that the PropertNames and PropertyValues will be matced regarding any case.
```csharp
var server = WireMockServer.Start();
server
.Given(Request
.Create()
.WithPath("/jsonmatcher3")
.WithBody(new JsonMatcher("{ \"x\": 42, \"s\": \"s\" }"), true)
.UsingPost())
.WithGuid("debaf408-3b23-4c04-9d18-ef1c020e79f2")
.RespondWith(Response.Create().WithBody(@"{ ""result"": ""jsonmatcher3 ok"" }"));
```
#### JSON Mapping option 3
``` js
{
"Guid": "debaf408-3b23-4c04-9d18-ef1c020e79f2",
"Request": {
"Path": {
"Matchers": [
{
"Name": "WildcardMatcher",
"Pattern": "/jsonmatcher1"
}
]
},
"Methods": [
"post"
],
"Body": {
"Matcher": {
"Name": "JsonMatcher",
"IgnoreCase": true,
"Pattern": "{ \"x\": 42, \"s\": \"s\" }"
}
}
},
"Response": {
"StatusCode": 200,
"Body": "{ \"result\": \"jsonmatcher3 ok\" }",
"UseTransformer": false
}
}
```
```
// matching
{ "X": 42, "s": "S" }
```
### JSON Path (JsonPathMatcher)
Deems a match if the attribute value is valid JSON and matches the JSON Path expression supplied.
A JSON body will be considered to match a path expression if the expression returns either a non-null single value (string, integer etc.), or a non-empty object or array.
#### C#
```csharp
var server = WireMockServer.Start();
server
.Given(
Request.Create().WithPath("/some/thing").UsingGet()
.WithBody(new JsonPathMatcher("$.things[?(@.name == 'RequiredThing')]"));
)
.RespondWith(Response.Create().WithBody("Hello"));
```
#### JSON Mapping
``` js
{
"Guid": "e4a600b8-9d6f-453f-90c6-3db2b0885ddb",
"Request": {
"Path": {
"Matchers": [
{
"Name": "WildcardMatcher",
"Pattern": "/jsonpath",
"IgnoreCase": false
}
]
},
"Methods": [
"put"
],
"Body": {
"Matcher": {
"Name": "JsonPathMatcher",
"Pattern": "$.things[?(@.name == 'RequiredThing')]"
}
}
},
"Response": {
"StatusCode": 200,
"BodyDestination": "SameAsSource",
"Body": "{ \"result\": \"JsonPathMatcher !!!\"}",
"UseTransformer": false
}
}
```
```
// matching
{ "things": { "name": "RequiredThing" } }
{ "things": [ { "name": "RequiredThing" }, { "name": "Wiremock" } ] }
// not matching
{ "price": 15 }
{ "things": { "name": "Wiremock" } }
```
