php - 将 API 调用从 PHP 和 cURL 转换为 ColdFusion cfhttp

问题描述

我正在尝试编写对在线测试公司的 API 调用。他们在 PHP 和 cURL 中提供了一个示例调用，我需要在 ColdFusion 11 中使用<CFHTTP>. 到目前为止，我的尝试失败了。我从他们的服务器/API 得到的唯一响应是：

Statuscode = "连接失败。状态码不可用。"

和

ErrorDetail = "I/O 异常：握手期间远程主机关闭连接"。

如果它正常工作，我会得到一个详细说明计算分数的 JSON 字符串。请注意，在下面的代码中，出于安全原因，我更改了一些值，除了它是原始代码。任何建议或意见将不胜感激，谢谢。

这是 ColdFusion/cfhttp 代码：

<cfoutput>
<cfset sdata = [
    {
        "customerid" = "ACompany",
        "studentid" = "test",
        "form" = "X",
        "age" = "18.10",
        "norms" = "grade",
        "grade" = "2"
    },
    {
        "scores" = [
        {"subtest"="math","score"="34"},
        {"score"="23","subtest"="lang"},
        {"score"="402","subtest"="rcomp"}
        ]
    }

<!--- create JSON string for request --->

     <cfhttpparam type="header" name="Authorization" value="AuthCode"/> 
     <cfhttpparam type="header" name="Content-Length" value = "#len(jsdata)#"/>
</cfhttp>

<!--- show results --->
cfhttp return status code: [#varx.statusCode#]<br> 
cfhttp return fileContent: [#varx.fileContent#]<br>
</cfoutput>

这是 PHP/cURL 代码：

<?php
    $data = array
    (
    "customerid" => "ACompany",
    "studentid" => "test",
    "scoringtype" => 2,
    "form" => "X",
    "age" => "18.10",
    "norms" => 'grade',
    "grade" => '2',
    "scores" => array(
        array("subtest" => "math", "score" => "34"),
        array("subtest" => "lang", "score" => "23"),
        array("subtest" => "rcomp", "score" => "402")
    ));

    $url = 'https://www.APIwebsite.php';
    $json_string = json_encode($data);

   $headers = array (
        "Content-Type: application/json; charset=utf-8",
        "Content-Length: " .strlen($json_string),
        "Authorization: AuthCode"
    );

    $channel = curl_init($url);
    curl_setopt($channel, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($channel, CURLOPT_CUSTOMREQUEST, "GET");
    curl_setopt($channel, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($channel, CURLOPT_POSTFIELDS, $json_string);
    curl_setopt($channel, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($channel, CURLOPT_CONNECTTIMEOUT, 10);

    $response = curl_exec($channel); // execute the request
    $statusCode = curl_getInfo($channel, CURLINFO_HTTP_CODE);
    $error = curl_error($channel);
    curl_close($channel);

    http_response_code($statusCode);
    if ( $statusCode != 200 ){
        echo "Status code: {$statusCode} \n".$error;
    } else {
        $data = json_decode($response,true);
        foreach ($data as $key => $value) {
            echo nl2br($key . ': ' . $value . "\n");
        }
    }
?>

解决方案

首先确保您提供的 url 正确（我知道它是用于示例但 .php 不是有效的域名扩展名），并且 SSL 证书有效

如果两者都正确，则应将请求方法更改POST为通过正文发送 json 数据

根据http语义

客户端不应在 GET 请求中生成正文。在 GET 请求中接收到的有效负载没有定义的语义，不能改变请求的含义或目标，并且可能导致一些实现拒绝请求并关闭连接，因为它有可能成为请求走私攻击

cfhttp 中有一个 charset 参数，所以你不需要在 header 中发送它

这是一个应该工作的代码

<cfset sdata = [
    {
        "customerid" = "ACompany",
        "studentid" = "test",
        "form" = "X",
        "age" = "18.10",
        "scoringtype" = 2,
        "norms" = "grade",
        "grade" = "2"
    },
    {
        "scores" = [
            {"subtest"="math","score"="34"},
            {"score"="23","subtest"="lang"},
            {"score"="402","subtest"="rcomp"}

        ]
    }
