What is the postman-token header attribute in generated code from Postman?
提问by d4rty
I have been using postman to explore a REST interface. When using Postman's code generation feature, regardless of which programming language I select, Postman will always add a postman-tokenattribute in the header. Why is it there?
我一直在使用邮递员来探索 REST 接口。在使用 Postman 的代码生成功能时，无论我选择哪种编程语言，Postman 都会postman-token在 header 中添加一个属性。为什么会在那里？
See for example PHP Curl:
参见示例 PHP Curl：
<?php
$curl = curl_init();
curl_setopt_array($curl, array(CURLOPT_URL => "https://myURL.com,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"authorization: Basic abcdefghijklmnop",
"cache-control: no-cache",
"postman-token: wt53gwg-e9bb-645d-g53d-e42f8765aut0"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}

This is primarily used to bypass a bug in Chrome. If an XMLHttpRequest is pending and another request is sent with the same parameters then Chrome returns the same response for both of them. Sending a random token avoids this issue. This can also help you distinguish between request on the server side.
这主要用于绕过 Chrome 中的错误。如果 XMLHttpRequest 处于挂起状态，并且使用相同参数发送了另一个请求，则 Chrome 会为它们返回相同的响应。发送随机令牌可避免此问题。这也可以帮助您区分服务器端的请求。
See docs/settings postman.
请参阅文档/设置邮递员。
