This can be used, for example, with the <code>HTTP In</code> node to ensure the payload is a parsed object even if an incoming request did not set its content-type correctly for the HTTP In node to do the conversion.</p> <p>If the node is configured to ensure the property is encoded as a String and it receives a String, no further checks will be made of the property. It will not check the String is valid JSON nor will it reformat it if the format option is selected.</p> <p>For more details about JSON Schema you can consult the specification <a href="http://json-schema.org/latest/json-schema-validation.html">here</a>.</p> </script> <script type="text/javascript"> RED.nodes.registerType('json',{ category: 'function', color:"#DEBD5C", defaults: { name: {value:""}, property: {value:"payload",required:true}, action: {value:""}, pretty: {value:false} }, inputs:1, outputs:1, icon: "parser-json.png", label: function() { return this.name||"json"; }, labelStyle: function() { return this.name?"node_label_italic":""; }, oneditprepare: function() { if (this.property === undefined) { $("#node-input-property").val("payload"); } $("#node-input-property").typedInput({default:'msg',types:['msg']}); $("#node-input-action").change(function() { if (this.value === "" || this.value === "str") { $(".node-json-to-json-options").show(); } else { $(".node-json-to-json-options").hide(); } }); $("#node-input-action").change(); } }); </script>
