angular – OAuth1(三条腿):签名无效

前端之家收集整理的这篇文章主要介绍了angular – OAuth1(三条腿):签名无效前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在Ionic2应用程序中配置OAuth时遇到问题.我没有使用任何框架/库作为OAuth的前端部分.

问题是我每次尝试检索access_token时都会收到401:Unauthorized:无效签名. (向下滚动代码,用注释缩进问题)

现在我的服务器被设置为三脚OAuth应用程序(as described fully here).这意味着将有3个端点:

1. / request_token(这个有效)

请求(GET参数):

oauth_version : ...
oauth_nonce: ....
oauth_timestamp: ...
oauth_consumer_key: ...
oauth_signature_method: ...
oauth_signature: ...

响应:

oauth_token: .... (temporary)
oauth_token_secret: ....

2. / authorize(这个也有效 – >打开浏览器进行身份验证)

请求(GET参数):

oauth_token: ....
oauth_callback: ....

响应

oauth_token: ....
oauth_verifier: ...

3. / access_token(这个不起作用)

请求(GET参数)

oauth_token: ....
oauth_verifier: ....
oauth_version : ...
oauth_nonce: ....
oauth_timestamp: ...
oauth_consumer_key: ...
oauth_signature_method: ...
oauth_signature: ...

响应:

oauth_token: .... (permanent)
oauth_secret: ....

尽管我以相同的方式设置了signatureBaseString并设置了密钥according to the guide,但最后一个不起作用

完整代码,包括其他2个电话(凌乱,我知道)

make it work,make it better,make it fast

目前在“让它工作”

login() {
    try{
        this.getRequestToken();
    }catch(err) {
        alert("ERROR: " + JSON.stringify(err));
    }

}

getRequestToken() {
    alert("in request token");
    let token_base_url = "https://servername/oauth/request_token";
    var oauth_nonce = this.generateNonce();
    var oauth_timestamp = this.getCurrentTimeStamp();

    let signatureBaseString = this.createSignatureBaseString(token_base_url,oauth_nonce,oauth_timestamp);
    let encryptedSignature = this.generateEncryptedSignature(signatureBaseString);

    let token_url = this.createOauthUrl(token_base_url,oauth_timestamp,encryptedSignature);

    this.http.get(token_url).subscribe(data => {
        this.doAuthorize(data);
    },err => {
        alert("ups: " + JSON.stringify(err));
    });
}

doAuthorize(data: any) {
    alert("in do authorize");

    let responseParameters = data.text().split("&");
    let requestToken = responseParameters[0].split("=")[1];
    let requestTokenSecret = responseParameters[1].split("=")[1];

    let authorize_url = `https://servername/oauth/authorize?oauth_token=${requestToken}&oauth_callback=${encodeURIComponent('http://localhost/callback')}`;
    let ref = cordova.InAppBrowser.open(authorize_url,'_blank','location=yes');

    ref.addEventListener("loadstart",(event) => {
        // little workaround to make this work without actually having a callback url
        if((event.url).indexOf('http://localhost/callback') == 0) {
            ref.removeEventListener("exit",(event)=>{});
            ref.close();

            this.getAccessToken(event.url,requestTokenSecret,requestToken);

好吧所以我不知道具体的解决方案是什么,但现在它的工作原理.对于按字母顺序排列基本字符串的人来说确实有一些东西.

这些是我用于OAuth的当前功能

创建基本字符串:

exampleUse() {
   let baseString = this.createSignatureBaseString('GET','someurl','asdfva323','15134234234',localStore.getItem('token'));
}

createSignatureBaseString(method: string,url: string,oauth_token?: string): string {
    let baseString = method+"&" + encodeURIComponent(url) + "&";
    baseString += encodeURIComponent(`oauth_consumer_key=${this.oauth_consumer_key}&`);
    baseString += encodeURIComponent(`oauth_nonce=${nonce}&`);
    baseString += encodeURIComponent(`oauth_signature_method=${this.oauth_signature_method}&`);
    baseString += encodeURIComponent(`oauth_timestamp=${timestamp}&`);
    if(oauth_token) {
        baseString += encodeURIComponent(`oauth_token=${oauth_token}&`);
    }
    baseString += encodeURIComponent(`oauth_version=1.0`);
    return baseString;
}

创建加密签名:

exampleUse() {
  let baseString = ...
  let mySecret = thatthissolutiontookmetwomonths;
  let signature = this.generateEncryptedSignature(baseString,mySecret);
}

generateEncryptedSignature(signatureBaseString: string,secret_signing_key); 
    let encryptedSignature = encodeURIComponent(CryptoJS.enc.Base64.stringify(oauth_signature));
    return encryptedSignature;
}

使用OAuth参数创建URL(以获取访问令牌等):

createOauthUrl(baseUrl: string,oauth_token?: string): string {
    var url = `${baseUrl}?`;
    url += `oauth_consumer_key=${this.oauth_consumer_key}&`;
    url += `oauth_nonce=${nonce}&`;
    url += `oauth_signature_method=HMAC-SHA1&`;
    url += `oauth_timestamp=${timestamp}&`;
    if(oauth_token) {
       url += `oauth_token=${oauth_token}&`;
    }
    url += `oauth_version=1.0&`;
    url += `oauth_signature=${signature}`;

    return url;
}

创建Authorization标头值(对每个经过身份验证的请求都是必需的):

exampleUse(){
  let headerValue = this.getHeaderValue('POST','someserver');
  let headers = new Headers();
  headers.append('Authorization',headerValue);
  let options = new RequestOptions(headers);

  this.http.post(url,some_data,options).then(res => {...});
}    

getHeaderValue(method: string,url: string): string {
    let headerValue = 'OAuth ';

    //these functions not included but they're pretty straightforward
    let timestamp = this.getCurrentTimeStamp();
    let nonce = this.generateNonce();

    let token = localStorage.getItem("u:access_token");
    let secret = localStorage.getItem("u:access_token:s");

    let baseString;
    baseString = this.createSignatureBaseString(method,url,nonce,timestamp,token);

    let signature = this.generateEncryptedSignature(baseString,secret);
    headerValue += `oauth_consumer_key="${this.oauth_consumer_key}"`;
    headerValue += `,oauth_token="${token}"`;

    headerValue += `,oauth_signature_method="HMAC-SHA1"`;
    headerValue += `,oauth_timestamp="${timestamp}"`;
    headerValue += `,oauth_nonce="${nonce}"`;
    headerValue += `,oauth_version="1.0"`;
    headerValue += `,oauth_signature="${signature}"`;

    return headerValue;
}

如果有人使用我上面分享代码遇到任何问题,请告诉我!我觉得我为此写了一个迷你图书馆.甚至可能把它合二为一.
