Creating an application/json HTTP POST Request

See more HTTP Examples

Demonstrates how to create an HTTP POST request having the Content-Type application/json, where the body of the HTTP request is the following JSON:

{
   "username" : "my_username",
   "password" : "my_password",
   "validation-factors" : {
      "validationFactors" : [
         {
            "name" : "remote_address",
            "value" : "127.0.0.1"
         }
      ]
   }
}

The generated HTTP request looks like this:

POST /something HTTP/1.1
Content-Type: application/json
Accept: application/json
Host: domain
Content-Length: 216

{
  "username": "my_username",
  "password": "my_password",
  "validation-factors": {
    "validationFactors": [
      {
        "name": "remote_address",
        "value": "127.0.0.1"
      }
    ]
  }
}

# This example demonstrates building an application/json request.

my $req = Chilkat2::HttpRequest->new;

# The ContentType, HttpVerb, and Path properties should
# always be explicitly set.
$req->HttpVerb('POST');
$req->Path('/something');
$req->ContentType('application/json');

# We may wish to add an "Accept" header to the request.
# This tells the server we'll accept an application/json response.
$req->AddHeader('Accept', 'application/json');

# We'll use Chilkat's JSON API to create the JSON body of the HTTP request.
my $json = Chilkat2::JsonObject->new;
$json->AppendString('username', 'my_username');
$json->AppendString('password', 'my_password');

my $vFactors = Chilkat2::JsonObject->new;
$json->AppendObject2('validation-factors', $vFactors);

my $vArray = Chilkat2::JsonArray->new;
$vFactors->AppendArray2('validationFactors', $vArray);

my $factorObj = Chilkat2::JsonObject->new;
$vArray->AddObjectAt2(0, $factorObj);
$factorObj->AppendString('name', 'remote_address');
$factorObj->AppendString('value', '127.0.0.1');

# Use the JSON for the HTTP request body
# By default, the Emit method will output compact JSON.
# This is best for generating the smallest size request.
# To generate a more human-readable (pretty-printed) JSON request body,
# set the EmitCompact property to FALSE
$json->EmitCompact(0);
$req->LoadBodyFromString($json->Emit(), 'utf-8');

# View the request that would be sent if HttpSReq was called:
my $requestMime = $req->GenerateRequestText();
print $requestMime, "\n";

# A few important comments about the HTTP request that is generated:
#
# 1) The Content-Length header is automatically generated based on the actual length of the MIME message
#    that follows the intial (topmost) MIME header.
# 2) The HOST header will automatically get filled in with the actual domain when HttpSReq
#    is called.
