Introduction
Aggregated data The national vehicle violation data interface has currently supported about 300 city violation queries and has been connected to tens of thousands of apps. It is convenient for car owners to know whether they have ever committed traffic violations at any time, and avoid unnecessary losses caused by forgetting or overdue processing of violation tickets.
API reference documentation: https://www.juhe.cn/docs/api/id/36
Example of API calling code for national vehicle violation query based on PHP
This code example is based on the call of the National Vehicle Violation Query API based on aggregated data. Before using it, you need:
Apply for an appkey for illegal inquiries through http://www.juhe.cn/docs/api/id/36
1. Introduce the encapsulated request class class.juhe.wz.php
header('Content-type:text/html;charset=utf-8');
include 'class.juhe.wz.php'; //Introduce files
2. Configuration parameters
//Configuration of interface basic information $appkey = '**********'; //The illegal query key you applied for $ wz = new wz ($ appkey);
3. Query the list of cities supported by illegal regulations
Since the supported cities will be updated from time to time, but not too frequently, you can cache the data, for example, update it every 3 hours, without requesting the interface every time.
$wzcitys = $wz->getCitys(); //Query all supported cities
$wzcitys = $wz->getCitys('GD'); //Query the cities under the specified province
The format of the returned data is as follows: (very important, it involves some conditions required for the next step of querying violations. For the specific field meaning, please refer to the official interface document, in which regist and registno can be ignored, and are only required for the old version)
{
"resultcode": "200",
"reason": "Successful return",
"result": [
{
"province": "北京",
"province_code": "BJ",
"citys": [
{
"city_name": "北京",
"city_code": "BJ",
"abbr": "京",
"engine": "1",
"engineno": "0",
"classa": "0",
"class": "0",
"classno": "0",
"regist": "0",
"registno": "0"
}
]
}
],
"error_code": 0
}
4. Inquire about the violation information of the vehicle
Basically, the city only supports small car query, so hpzl can be omitted.
//According to the required query conditions, query the violation information of the vehicle
$city = 'GD_DG'; //city code, must be passed
$carno = 'Guangdong S*****'; //The license plate number, must be passed
$engineno = '****'; //Engine number, the required city must be passed
$classno = '*****'; //Frame number, the required city must be passed
$wzResult = $wz->query($city,$carno,$engineno,$classno);
if($wzResult['error_code'] ==0){
if($wzResult['result']['lists']){
foreach($wzResult['result']['lists'] as $key =>$w){
//The following is modified according to the actual business needs
echo $w['area']." ".$w['date']." ".$w['act']." ".$w['fen']." ".$w['money']."<br>";
}
}else{
echo "The car has no illegal record";
}
}else{
// query failed
echo $wzResult['error_code'].":".$wzResult['reason'];
}
