json schema validate

为了检测API返回的数据结构是否正确，刚好chrome的插件postman可以做这件事。其实它用的也是tv4的库来验证。又找了一些开源的验证工具。如下
在线验证工具：
只支持http://json-schema.org/draft-03/schema#

schema

{
  "$schema": "http://json-schema.org/draft-03/schema#",
  "title": "App",
  "description": "APP LIST",
  "type": "array",  
  "properties":{
  	"appID": {
     	"type": "string",
        "required":true
     },
     "appName":{
         "type": "string",
        "required":true
      },
    "appCaption":{
         "type": "string",
        "required":true
      },
      "icon":{
        "type":"string",
 "required":true
      }
  }
}

json:

[{"appID":"1","appName":"push","appCaption":"push ","icon":""},{"appID":"52","appName":"Sample(\u4e13\u7528)","appCaption":"Sample(\u4e13\u7528)","icon":""},{"appID":"64","appName":"\u65b0\u73af\u5883\u6d4b\u8bd5dddd","appCaption":"\u65b0\u73af\u5883\u6d4b\u8bd5","icon":""}]

dojo json schema:

Example use of dojox.json.schema

Due to its use of the Dojo CDN distribution on google.com, this HTML file MUST be accessed through an HTTP server such as Apache.  file:/// URIs won't work.'

在postman中的json validate

tests["Status code is 200"] = responseCode.code === 200;

var data = JSON.parse(responseBody);
tests["status"] = data.status === true;
tests["info"] = data.info === "success";
var appData = data.data;
tests['appCount'] = appData.length === 3;
var schema = {
  "$schema": "http://json-schema.org/draft-04/schema#",
  "title": "App",
  "description": "APP LIST",
  "type": "object",  
  "properties":{
  	"appID": {
     	"type": "string"
     },
     "appName":{
         "type": "string"
      },
    "appCaption":{
         "type": "string"
      },
      "icon":{
        "type":"string",
        "required":true,
        "pattern":"^http://"
      }
  }
};

$.each(appData, function (i) {
    var app = this;
  tests['appName'+i] = tv4.validate(app, schema); 
})
