为什么我的PHP代码返回错误400“您的浏览器发送了一个无效的请求”？

Question

对API vv的vv请求

    $data = $_POST['csrf'];
    $headers = [
        "x-csrf-token: $data\r\n".
        "Content-Type: application/json\r\n".
        "Accept: application/json\r\n"
    ];
    $data = <<<DATA
    {
        "username": "string",
        "password": "string",
        "gender": "Unknown",
        "birthday": "2021-11-22T23:29:51.656Z",
        "isTosAgreementBoxChecked": true,
        "email": "string",
        "locale": "string",
        "assetIds": [
            0
        ],
        "bodyColorId": 0,
        "bodyTypeScale": 0,

            "acquisitionReferrer": "string",
            "medium": "string",
            "source": "string",
            "campaign": "string",

            "matchType": "string",
            "sendInfo": true,
            "requestSessionId": "string",
            "offerId": "string"
        },
        "agreementIds": [
            "string"
        ],
        "identityVerificationResultToken": "string",
        "captchaId": "string",
        "captchaToken": "string",
        "captchaProvider": "string"
    }
    DATA;
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://auth.roblox.com/v1/signup');
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    curl_close($ch);
}

服务器告诉我“错误400，您的浏览器发送了无效的请求”。问题在于x-csrf-令牌，当我将其作为字符串“x token: j8acha7hffh”时，它可以工作。当我将其命名为“：$data”时，它会返回一个错误。我尝试过不同的方法来处理这个错误。我已经改变了标题。尝试了不同的请求方式。还是没有什么能纠正我的错误。我是新的PHP，请帮助！

Answer 1

您正在使用$header作为一个array，但是它包含长string，因为我怀疑长字符串中的行分隔符/r/n在这里造成了麻烦。

因此，更改充满新行分隔符的一个值数组。

$headers = [
    "x-csrf-token: $data\r\n".
    "Content-Type: application/json\r\n".
    "Accept: application/json\r\n"
];

具有多个值的数组。

$headers = [
    "x-csrf-token: $data",
    "Content-Type: application/json",
    "Accept: application/json",
];

CURLOPT_HTTPHEADER格式数组中要设置的header字段数组(“内容-类型:文本/平原”、“内容-长度:100”)

尝试这样做：

“x-csrf-令牌：”.$data.“\r”。
