本文介绍了获取雅虎联系人列表中的C＃应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

作为指导 https://developer.yahoo.com/oauth/guide /oauth-requesttoken.html ，下面是我做了什么通过OAuth获得雅虎联系人列表：

请GET请求到 https://api.login.yahoo.com/oauth/v2/get_request_token
获得组oauth_token和oauth_token_secret，我成功地让他们

示例网址：

  OAuthBase誓=新OAuthBase（）; 
 
字符串URL =https://api.login.yahoo.com/oauth/v2/get_request_token？ + 
 
oauth_nonce =+ oath.GenerateNonce（）+ 
及放大器; oauth_timestamp =+ oath.GenerateTimeStamp（）+ 
及放大器; oauth_consumer_key =+ consumerKey + 
及放大器; oauth_signature_method =明文+ 
及放大器; oauth_signature =+ consumerSecret +％26+ //％26，如果明文
及放大器; oauth_version = 1.0+ 
&放大器; oauth_callback =+OOB;

使用步骤1中的组oauth_token。做一个GET请求 https://api.login.yahoo.com/ OAuth的/ V2 / request_auth？组oauth_token = {令牌}，这回我oauth_verifier

使用步骤1和2的paramters使GET请求 https://api.login.yahoo.com/oauth/v2/get_token ，它返回我新组oauth_token，oauth_token_secret，oauth_session_handle，xoauth_yahoo_guid

示例网址：

 字符串SIG = consumerSecret +％26+ OauthTokenSecret; 
字符串URL =https://api.login.yahoo.com/oauth/v2/get_token？ + 
 
oauth_consumer_key =+ consumerKey + 
及放大器; oauth_signature_method =明文+ 
及放大器; oauth_signature =+ SIG + 
及放大器; oauth_timestamp = + oath.GenerateTimeStamp（）+ 
及放大器; oauth_version = 1.0+ 
及放大器;组oauth_token =+ OAuthToken + 
及放大器; oauth_nonce =+ oath.GenerateNonce（）+ 
&放大器; oauth_verifier =+ oauth_verifier;

<醇开始=4>

最后一步是获取联系人列表：
我做一个GET请求 https://social.yahooapis.com/v1/user / {} xoauth_yahoo_guid /联系人？格式= JSON

示例

 开放的URI =新的URI（URL）; 
串随机数= oath.GenerateNonce（）; 
串的timeStamp = oath.GenerateTimeStamp（）; 
串normalizedUrl; 
串normalizedRequestParameters; 
串SIG = oath.GenerateSignature（URI，客户端ID，clientSecret，yahooToken.OAuthToken，
 yahooToken.OauthTokenSecret，GET，时间戳，现时，OAuthBase.SignatureTypes.HMACSHA1，
 OUT normalizedUrl，出normalizedRequestParameters）;

功能GenerateSignature：

 公共字符串GenerateSignature（URI链接，串consumerKey，串consumerSecret，字符串标记，字符串tokenSecret，串列举HTTPMethod，字符串的timeStamp，串现时，SignatureTypes signatureType，出字符串normalizedUrl，出字符串normalizedRequestParameters）
 { 
 normalizedUrl = NULL; 
 normalizedRequestParameters = NULL; 
 
开关（signatureType）
 {
情况下SignatureTypes.PLAINTEXT：
返回HttpUtility.UrlEncode（的String.Format（{0}&放大器; {1}， consumerSecret，tokenSecret））; 
情况下SignatureTypes.HMACSHA1：
串signatureBase = GenerateSignatureBase（URL，consumerKey，令牌，tokenSecret，列举HTTPMethod，时间戳，现时，HMACSHA1SignatureType，出normalizedUrl，出normalizedRequestParameters）; 
 
 HMACSHA1 HMACSHA1 =新HMACSHA1（）; 
 hmacsha1.Key = Encoding.ASCII.GetBytes（的String.Format（{0}&放大器; {1}，以UrlEncode（consumerSecret），string.IsNullOrEmpty（tokenSecret）：以UrlEncode（tokenSecret））） ; 
 
返回GenerateSignatureUsingHash（signatureBase，HMACSHA1）; 
情况下SignatureTypes.RSASHA1：
抛出新NotImplementedException（）; 
默认：
抛出新的ArgumentException（未知的签名类型，signatureType）; 
} 
}

请要求：

 使用（VAR的客户=新的WebClient（））
 {
串authenHeader =OAuth的+ 
的境界= \\ \\yahooapis.com\+ 
，oauth_consumer_key = \+ consumerKey +\+ 
，oauth_nonce = \+ +随机数\ + 
，oauth_signature_method = \HMAC-SHA1\+ 
，oauth_timestamp = \+ +的timeStamp\+ 
组oauth_token = \\ \\+ OAuthToken +\+ 
，oauth_version = \1.0\+ 
，oauth_signature = \+ HttpUtility.UrlEncode（SIG）+ \; 
 
 client.Headers.Set（授权，authenHeader）; 
串responseString = client.DownloadString（URL）; 
}

但雅虎给我发（401）未经授权的响应，你能告诉我在哪里'错了？

解决方案

我意识到，我停留在完全相同的地方

System.Net.WebException：远程服务器返回错误：（401）未经授权。在...

 私人的ArrayList GetEmailContacts（）{
 OAuthBase的OAuth =新OAuthBase ..GetEmailContacts（）（ ）; 
 
乌里URI =新的URI（https://social.yahooapis.com/v1/user/+ OauthYahooGuid +/联系人格式的XML =？）; 
串随机数= oauth.GenerateNonce（）; 
串的timeStamp = oauth.GenerateTimeStamp（）; 
串normalizedUrl; 
串normalizedRequestParameters; 
串SIG = oauth.GenerateSignature（URI，this.sConsumerKey，this.sConsumerSecret，OauthToken，OauthTokenSecret，GET，时间戳，现时，OAuthBase.SignatureTypes.HMACSHA1，出normalizedUrl，出normalizedRequestParameters）; 
 
 StringBuilder的sbGetContacts =新的StringBuilder（uri.ToString（））; 
 
尝试{
串returnStr =的String.Empty; 
 HttpWebRequest的REQ =（HttpWebRequest的）WebRequest.Create（sbGetContacts.ToString（））; 
 req.Accept =application / xml进行; 
 req.Method =GET; 
 ArrayList的电子邮件=新的ArrayList（）; 
 
串authHeader =授权：OAuth的+ 
的境界= \yahooapis.com\+ 
，oauth_consumer_key = \+这一点。 sConsumerKey +\+ 
，oauth_nonce = \+ +随机数\+ 
，oauth_signature_method = \HMAC-SHA1\+ 
，oauth_timestamp = \+ +的timeStamp\+ 
组oauth_token = \+ OauthToken +\+ 
，oauth_version = \ 1.0\+ 
，oauth_signature = \+ HttpUtility.UrlEncode（SIG）+\; 
 
 req.Headers.Add（authHeader）; 
 
使用（HttpWebResponse RES =（HttpWebResponse）req.GetResponse（））{

SO，我发现这个问题。香港专业教育学院改变了内容格式从XML到JSON

改变了以下内容：

 私人的ArrayList GetEmailContacts（）{
 OAuthBase的OAuth =新OAuthBase（）; 
 
乌里URI =新的URI（https://social.yahooapis.com/v1/user/+ OauthYahooGuid +/联系人格式= JSON？）; 
串随机数= oauth.GenerateNonce（）; 
串的timeStamp = oauth.GenerateTimeStamp（）; 
串normalizedUrl; 
串normalizedRequestParameters; 
串SIG = oauth.GenerateSignature（URI，this.sConsumerKey，this.sConsumerSecret，OauthToken，OauthTokenSecret，GET，时间戳，现时，OAuthBase.SignatureTypes.HMACSHA1，出normalizedUrl，出normalizedRequestParameters）; 
 
 StringBuilder的sbGetContacts =新的StringBuilder（uri.ToString（））; 
 
尝试{
串returnStr =的String.Empty; 
 HttpWebRequest的REQ =（HttpWebRequest的）WebRequest.Create（sbGetContacts.ToString（））; 
 req.Accept =应用/ JSON; 
 req.ContentType =应用/ JSON; 
 req.Method =GET; 
 ArrayList的电子邮件=新的ArrayList（）; 
 
串authHeader =授权：OAuth的+ 
的境界= \yahooapis.com\+ 
，oauth_consumer_key = \+这一点。 sConsumerKey +\+ 
，oauth_nonce = \+ +随机数\+ 
，oauth_signature_method = \HMAC-SHA1\+ 
，oauth_timestamp = \+ +的timeStamp\+ 
组oauth_token = \+ OauthToken +\+ 
，oauth_version = \ 1.0\+ 
，oauth_signature = \+ HttpUtility.UrlEncode（SIG）+\; 
 
 req.Headers.Add（authHeader）; 
 
使用（HttpWebResponse RES =（HttpWebResponse）req.GetResponse（））{

当我提出，改变它突然返回的电子邮件，并没有更多的406错误代码。

我希望这可以帮助别人..不知道，为什么XML停止工作

As guidance on https://developer.yahoo.com/oauth/guide/oauth-requesttoken.html, Below are what I did with OAuth to get Yahoo contact list:

Make a GET request to https://api.login.yahoo.com/oauth/v2/get_request_token to get oauth_token and oauth_token_secret, I successfully get them.

Example url:

OAuthBase oath = new OAuthBase();

string url = "https://api.login.yahoo.com/oauth/v2/get_request_token?" +

          "oauth_nonce=" + oath.GenerateNonce() +
          "&oauth_timestamp=" + oath.GenerateTimeStamp() +
          "&oauth_consumer_key=" + consumerKey+
          "&oauth_signature_method=plaintext" +
          "&oauth_signature=" + consumerSecret + "%26" + //%26 if plaintext
          "&oauth_version=1.0" +
          "&oauth_callback=" + "oob";

Using oauth_token of step 1. to make a GET request to https://api.login.yahoo.com/oauth/v2/request_auth?oauth_token={token}, It returned me oauth_verifier
Using paramters of step 1 and 2 to make GET request to https://api.login.yahoo.com/oauth/v2/get_token , it returned me new oauth_token , oauth_token_secret, oauth_session_handle, xoauth_yahoo_guid.

Example url:

string sig = consumerSecret + "%26" + OauthTokenSecret;
string url = "https://api.login.yahoo.com/oauth/v2/get_token?" +

          "oauth_consumer_key=" + consumerKey+
          "&oauth_signature_method=plaintext" +
          "&oauth_signature=" + sig +
          "&oauth_timestamp=" + oath.GenerateTimeStamp() +
          "&oauth_version=1.0" +
          "&oauth_token=" + OAuthToken +
          "&oauth_nonce=" + oath.GenerateNonce() +
          "&oauth_verifier=" + oauth_verifier;

The final step is to get the contact list: I make a GET request to https://social.yahooapis.com/v1/user/{xoauth_yahoo_guid}/contacts?format=json

Example

Uri uri = new Uri(url);
string nonce = oath.GenerateNonce();
string timeStamp = oath.GenerateTimeStamp();
string normalizedUrl;
string normalizedRequestParameters;
string sig = oath.GenerateSignature(uri, clientId, clientSecret, yahooToken.OAuthToken,
    yahooToken.OauthTokenSecret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1,
    out normalizedUrl, out normalizedRequestParameters);

Function GenerateSignature:

public string GenerateSignature(Uri url, string consumerKey, string consumerSecret, string token, string tokenSecret, string httpMethod, string timeStamp, string nonce, SignatureTypes signatureType, out string normalizedUrl, out string normalizedRequestParameters)
{
    normalizedUrl = null;
    normalizedRequestParameters = null;

    switch (signatureType)
    {
        case SignatureTypes.PLAINTEXT:
            return HttpUtility.UrlEncode(string.Format("{0}&{1}", consumerSecret, tokenSecret));
        case SignatureTypes.HMACSHA1:
            string signatureBase = GenerateSignatureBase(url, consumerKey, token, tokenSecret, httpMethod, timeStamp, nonce, HMACSHA1SignatureType, out normalizedUrl, out normalizedRequestParameters);

            HMACSHA1 hmacsha1 = new HMACSHA1();
            hmacsha1.Key = Encoding.ASCII.GetBytes(string.Format("{0}&{1}", UrlEncode(consumerSecret), string.IsNullOrEmpty(tokenSecret) ? "" : UrlEncode(tokenSecret)));

            return GenerateSignatureUsingHash(signatureBase, hmacsha1);
        case SignatureTypes.RSASHA1:
            throw new NotImplementedException();
        default:
            throw new ArgumentException("Unknown signature type", "signatureType");
    }
}

Make request:

using (var client = new WebClient())
{
    string authenHeader = "OAuth " +
        "realm=\"yahooapis.com\"" +
        ",oauth_consumer_key=\"" + consumerKey+ "\"" +
        ",oauth_nonce=\"" + nonce + "\"" +
        ",oauth_signature_method=\"HMAC-SHA1\"" +
        ",oauth_timestamp=\"" + timeStamp + "\"" +
        ",oauth_token=\"" + OAuthToken + "\"" +
        ",oauth_version=\"1.0\"" +
        ",oauth_signature=\"" + HttpUtility.UrlEncode(sig) + "\"";

    client.Headers.Set("Authorization", authenHeader);
    string responseString = client.DownloadString(url);
}

But Yahoo sends me (401) Unauthorized response, Could you tell me where I'm wrong ?

解决方案

I realized that I am stuck at the exact same place

System.Net.WebException: The remote server returned an error: (401) Unauthorized. at ..GetEmailContacts() in ...

  private ArrayList GetEmailContacts() {
    OAuthBase oauth = new OAuthBase();

    Uri uri = new Uri("https://social.yahooapis.com/v1/user/" + OauthYahooGuid + "/contacts?format=XML");
    string nonce = oauth.GenerateNonce();
    string timeStamp = oauth.GenerateTimeStamp();
    string normalizedUrl;
    string normalizedRequestParameters;
    string sig = oauth.GenerateSignature(uri, this.sConsumerKey, this.sConsumerSecret, OauthToken, OauthTokenSecret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1, out normalizedUrl, out normalizedRequestParameters);

    StringBuilder sbGetContacts = new StringBuilder(uri.ToString());

    try {
    string returnStr = string.Empty;
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sbGetContacts.ToString());
    req.Accept = "application/xml";
    req.Method = "GET";
    ArrayList emails = new ArrayList();

    string authHeader = "Authorization: OAuth " +
    "realm=\"yahooapis.com\"" +
    ",oauth_consumer_key=\"" + this.sConsumerKey + "\"" +
    ",oauth_nonce=\"" + nonce + "\"" +
    ",oauth_signature_method=\"HMAC-SHA1\"" +
    ",oauth_timestamp=\"" + timeStamp + "\"" +
    ",oauth_token=\"" + OauthToken + "\"" +
    ",oauth_version=\"1.0\"" +
    ",oauth_signature=\"" + HttpUtility.UrlEncode(sig) + "\"";

    req.Headers.Add(authHeader);

    using (HttpWebResponse res = (HttpWebResponse)req.GetResponse()) {

:/ sighz

SO I found the issue. Ive changed the content format from XML to JSON

changed the following:

private ArrayList GetEmailContacts() {
    OAuthBase oauth = new OAuthBase();

    Uri uri = new Uri("https://social.yahooapis.com/v1/user/" + OauthYahooGuid + "/contacts?format=json");
    string nonce = oauth.GenerateNonce();
    string timeStamp = oauth.GenerateTimeStamp();
    string normalizedUrl;
    string normalizedRequestParameters;
    string sig = oauth.GenerateSignature(uri, this.sConsumerKey, this.sConsumerSecret, OauthToken, OauthTokenSecret, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1, out normalizedUrl, out normalizedRequestParameters);

    StringBuilder sbGetContacts = new StringBuilder(uri.ToString());

    try {
        string returnStr = string.Empty;
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sbGetContacts.ToString());
        req.Accept = "application/json";
        req.ContentType = "application/json";
        req.Method = "GET";
        ArrayList emails = new ArrayList();

        string authHeader = "Authorization: OAuth " +
        "realm=\"yahooapis.com\"" +
        ",oauth_consumer_key=\"" + this.sConsumerKey + "\"" +
        ",oauth_nonce=\"" + nonce + "\"" +
        ",oauth_signature_method=\"HMAC-SHA1\"" +
        ",oauth_timestamp=\"" + timeStamp + "\"" +
        ",oauth_token=\"" + OauthToken + "\"" +
        ",oauth_version=\"1.0\"" +
        ",oauth_signature=\"" + HttpUtility.UrlEncode(sig) + "\"";

        req.Headers.Add(authHeader);

        using (HttpWebResponse res = (HttpWebResponse)req.GetResponse()) {

When I made that change it suddenly returned the emails and no more 406 error code.

I hope that this helps someone.. no idea as to why xml stopped working.
