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

目前在“让它工作”

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.
原文链接:/angularjs/141801.html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; }
