National Vehicle Violation Inquiry API Calling Code Example Based on PHP
This code example is a call to the National Vehicle Violation Inquiry API based on aggregated data. Before using it, you need to:
Apply for an appkey for violation query through http://www.juhe.cn/docs/api/id/36
1. Introduce the encapsulated request class class.juhe.wz.phpheader('Content-type:text/html;charset=utf-8'); <br>
include 'class.juhe.wz.php'; //Introduction file 2. Configuration parameters //Interface basic information configuration <br>
$appkey = '**********'; //The violation query key you applied for <br>
$wz = new wz($appkey); 3. Query the list of supported cities for violations
Since the supported cities will be updated from time to time, but not too frequently, you can cache this data, for example, update it every 3 hours, without requesting the interface every time. $wzcitys = $wz->getCitys(); //Query all supported cities <br>
$wzcitys = $wz->getCitys('GD'); //Query the cities in the specified province The returned data format is as follows: (very important, it involves some conditions required for querying violations in the next step, and the specific field meanings You can refer to the official interface document, where register and registerno can be ignored and are only needed for older versions){ <br>
"resultcode": "200", <br>
"reason": "Successful return", <br>
"result": [ <br>
“province”: “Beijing”, <br>
"province_code": "BJ", <br>
"cities": [ <br>
"city_name": "Beijing", <br>
"city_code": "BJ", <br>
"abbr": "京", <br>
"engine": "1", <br>
"engineno": "0", <br>
"classa": "0", <br>
"class": "0", <br>
"classno": "0", <br>
"regist": "0", <br>
"registno": "0" <br>
} <br>
], <br>
"error_code": 0 <br>
} <br>4. Query vehicle violation information<br>Basically, cities only support small car queries, so hpzl can be omitted. <code class="prettyprint linenums lang-php">//Query the vehicle’s violation information according to the required query conditions <br>
$city = 'GD_DG'; //City code, must be passed <br>
$carno = 'Guangdong S*****'; //License plate number, must be passed <br>
$engineno = '****'; //Engine number, the required city must be passed <br>
$classno = '*****'; //Vehicle number, the required city must be passed <br>
$wzResult = $wz->query($city,$carno,$engineno,$classno); <br>
if($wzResult['error_code'] ==0){ <br>
If($wzResult['result']['lists']){ <br>
foreach($wzResult['result']['lists'] as $key =>$w){ <br>
//The following is modified according to actual business needs <br>
echo $w['area']." ".$w['date']." ".$w['act']." ".$w['fen']." ".$w['money ']."<br>"; <br>
} <br>
}else{ <br>
echo "This car has no violation record"; <br>
} <br>
}else{ <br>
//Query unsuccessful <br>
echo $wzResult['error_code'].":".$wzResult['reason']; <br>
} 5. Complete code of class.juhe.wz.php <!--?php <br />
