Must read for PHP developers! Taobao order query API document analysis

With the rapid development of e-commerce, more and more developers have poured into the e-commerce field. As one of the most important players in the e-commerce platform, Taobao provides a rich API interface and provides developers with convenient and fast development tools. Among them, Taobao order query API is a commonly used function. This article will analyze the documentation of this API to help PHP developers better understand and use it.

1. Get API key
   Before using the Taobao order query API, developers need to obtain the API key first. In the developer center of Taobao open platform, you can apply for your own API key. After obtaining the API key, developers need to keep it to ensure security and correct use.
2. Request URL and parameters
   The request URL of Taobao order query API is:
   https://gw.api.taobao.com/router/rest

where , there are the following required parameters:

• method: Specify the API method to call, such as: taobao.trade.get
• app_key: Developer’s application key
• session: Authorized token, used to verify user identity
• timestamp: Call timestamp, in the format of yyyy-MM-dd HH:mm:ss (time zone is GMT 8)
• v: API protocol version number, currently 2.0
• sign: signature string, used for signature verification of parameters

In addition to the required parameters, you can also add them according to your needs Other optional parameters, such as: fields (returned fields), tid (transaction order number), etc. Specific parameters can be viewed in the API documentation.

3. Construct a signature string
   Before requesting the Taobao order query API, all parameters need to be signed. Among them, the signature algorithm uses HMAC-SHA1. The signature string needs to be constructed according to certain rules:
4. Sort all request parameters in dictionary order of parameter names
5. Connect the parameter names and parameter values ​​with "=" to form "parameters" In the form of "name=parameter value"
6. Connect each "parameter name=parameter value" string with "&"
7. Splice app_secret at the end of the signature string
8. HMAC-SHA1 signature for the spliced ​​string

Code example for constructing the signature string:

function buildRequestSign($params, $appSecret) {
    ksort($params);
    $signString = '';
    foreach ($params as $key => $value) {
        $signString .= $key . "=" . $value . "&";
    }
    $signString .= "app_secret=" . $appSecret;
    return strtoupper(hash_hmac("sha1", $signString, $appSecret));
}

4. Send the request and parse the result
   Construct the signature After the string, put the signature value into the request parameter and send an HTTP request to the Taobao order query API. According to the requirements in the API document, the request method can be GET or POST. Here we take the GET method as an example.

Code example of using curl to send GET request:

$url = "https://gw.api.taobao.com/router/rest";
$response = file_get_contents($url . '?' . http_build_query($params));
$result = json_decode($response, true);

Code example of parsing the returned result:

if ($result['error_response']) {
    echo "API调用失败：" . $result['error_response']['msg'];
} else {
    echo "API调用成功：";
    // 处理返回结果
}

By parsing the returned result, developers can obtain the order Relevant information, such as order number, buyer's name, product name, payment amount, etc.

Summary:
This article analyzes and explains the documentation of Taobao order query API to help PHP developers better understand and use this important API interface. By accurately constructing parameters, signature strings, and sending HTTP requests, developers can quickly obtain order-related information, providing a convenient tool for e-commerce platform application development. I hope this article can provide help and guidance for PHP developers in using Taobao order query API.
