jsonshcema.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#
https://json-schema-validator.herokuapp.com/

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:

在postman中的json validate
[code]
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);
})

[/code]
