swift - http header 中的 Yelp 身份验证

Question

我只是尝试使用 yelp api ( https://www.yelp.com/developers/documentation/v2/authentication ) 搜索营业地点。但是，尽管在 header 中添加了必填字段，但我无法通过他们的服务进行身份验证。这是代码:

    private func generateAuthorizationHeaders() -> String {
    let consumer = "oauth_consumer_key=\"\(consumerKey!)\""
    let accessToken = "oauth_token=\"\(token!)\""
    let signatureMethod = "oauth_signature_method=\"HMAC-SHA1\""
    let signature = "oauth_signature=\"\(token!.hmacsha1(key: tokenSecret!))\"" //More than likely wrong
    let timestamp = "oauth_timestamp=\"\(Int(Date.timeIntervalBetween1970AndReferenceDate))\""
    let uniqueString = "oauth_nonce=\"nvgnhvfvfvffvvf\""
    return "\(consumer),\(accessToken),\(signatureMethod),\(signature),\(timestamp),\(uniqueString)"
}

func search(for place: String, at location: CLLocationCoordinate2D) {
    let authorization = generateAuthorizationHeaders()
    let string = "https://api.yelp.com/v2/search?term=\(place)&ll=\(location.latitude),\(location.longitude)"
    let request = NSMutableURLRequest(url: NSURL(string: string) as! URL)
    request.httpMethod = "GET"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("\(authorization)", forHTTPHeaderField: "Authorization")

    URLSession.shared.dataTask(with: request as URLRequest, completionHandler: {data, response, error in
       ... JSON stuff
    }).resume()

我收到的错误信息是:

{
error =     {
    field = "oauth_consumer_key";
    id = "MISSING_PARAMETER";
    text = "One or more parameters are missing in request";
};

有人能发现问题吗？谢谢。

看起来您缺少 OAuth。

试试这个:

return "OAuth \(consumer),\(accessToken),\(signatureMethod),\(signature),\(timestamp),\(uniqueString)
