Twitter API 尝试请求令牌时出错

Question

我正在尝试执行第一步，即使用 Twitter api 端点为用户获取访问令牌。但是 request_token 端点不工作，我得到了一个通用的 500 内部服务器错误。这是我试图达到的终点：

POST https://api.twitter.com/oauth/request_token?oauth_callback=http%3A%2F%2example.com%2Fapi%2Ftwitter%2Foauth

Authorization: OAuth oauth_nonce="kYjzVBB8Y0ZFabxSWbWovY3uYSQ2pTgmZeNu2VS4cg", oauth_callback="http%3A%2F%2example.com%2Fapi%2Ftwitter%2Foauth", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1630988166522", oauth_consumer_key="<MY_CONSUMER_KEY>", oauth_signature="8cVT5tNumrTit77OZkiaA1fSo7Y=", oauth_version="1.0"

回调为http:///api/twitter/oauth

回调也在我的 Twitter 应用程序设置中定义....

oauth_signature 是使用以下 javascript 创建的：

function createSignature() {
    var str = 
        "include_entities=true" +
        "&oauth_callback=" + "http%3A%2F%2example.com%2Fapi%2Ftwitter%2Foauth" +
        "&oauth_consumer_key=" + "<MY_CONSUMER_KEY>" +
        "&oauth_nonce=kYjzVBB8Y0ZFabxSWbWovY3uYSQ2pTgmZeNu2VS4cg" +
        "&oauth_signature_method=HMAC-SHA1" +
        "&oauth_timestamp=" + Date.now() +
        "&oauth_token=" + "<MY_APP_AUTH_ACCESS_TOKEN>" +
        "&oauth_version=1.0"
        ;

    var signature_base_string = 
        "POST" +
        "&https%3A%2F%2Fapi.twitter.com%2F1.1%2Foauth%2Frequest_token" +
        "&" + encodeURIComponent(str);

    var signing_key = 
        "<MY_CONSUMER_SECRET>" +
        "&" +
        "<MY_APP_AUTH_ACCESS_SECRET>";

    var hash = CryptoJS.HmacSHA1(signature_base_string, signing_key);
    var base64 = hash.toString(CryptoJS.enc.Base64);

    return base64;
}

我错过了什么？？

谢谢！

Answer 1

我想通了。我在生成签名时遗漏了一些信息。它应该是这样的：

var CryptoJS = require("crypto-js");
function createSignature() {

    var str =  
        "oauth_callback=" + encodeURIComponent("<MY_CALLBACK_URL>") +
        "&oauth_consumer_key=" + "<CONSUMER_KEY>" +
        "&oauth_nonce=kYjzVBB8Y0ZFabxSWbWovY3uYSQ2pTgmZeNu2VS4cg" +
        "&oauth_signature_method=HMAC-SHA1" +
        "&oauth_timestamp=" + Math.floor((new Date()).getTime() / 1000) +
        "&oauth_token=" + "<TWITTER_ACCESS_TOKEN>" +
        "&oauth_version=1.0"
        ;

    var signature_base_string = 
        "POST" +
        "&" + encodeURIComponent("https://api.twitter.com/oauth/request_token") +
        "&" + encodeURIComponent(str);

    var signing_key = 
        "<CONSUMER_SECRET>" +
        "&" +
        "<TOKEN_SECRET>";

    var hash = CryptoJS.HmacSHA1(signature_base_string, signing_key);
    return encodeURIComponent(hash.toString(CryptoJS.enc.Base64));
}

其他都正确...

谢谢！
