Question

我无法调用Yahoo Gemini API从我的C＃控制台（桌面）应用程序访问Yahoo Gemini Advertising。

以下是我使用的步骤：

在https://developer.yahoo.com/apps/create/上创建已安装的应用程序。这给了我{Client ID}和{Client Secret}。
https://api.login.yahoo.com/oauth2/request_auth?client_id={Client ID} &redirect_uri=oob&response_type=code&language=en-us。这将带我到我登录的yahoo登录界面。按下“同意”按钮，下一个屏幕显示七个字母的授权码（比如nzbcns9）。我写下了这个授权码。

然后我使用以下代码尝试获取访问令牌：

class Program
{
static void Main(string[] args)
{
    string clientId = {Client ID};
    string secret = {Client Secret};

    var request = WebRequest.Create(@"https://api.login.yahoo.com/oauth2/get_token");
    request.Method = "POST";

    SetBasicAuthHeader(request, clientId, secret);

    string postData = "grant_type=authorization_code&redirect_uri=oob&code=nzbcns9";
    ASCIIEncoding encoding = new ASCIIEncoding();
    byte[] byte1 = encoding.GetBytes(postData);
    request.ContentLength = byte1.Length;
    Stream dataStream = request.GetRequestStream();
    dataStream.Write(byte1, 0, byte1.Length);
    dataStream.Close();

    request.ContentType = "application/x-www-form-urlencoded";
    var response = request.GetResponse();
    Console.WriteLine(((HttpWebResponse)response).StatusDescription);
}

static void SetBasicAuthHeader(WebRequest request, String userName, String userPassword)
{
    string authInfo = userName + ":" + userPassword;
    authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
    request.Headers["Authorization"] = "Basic " + authInfo;
}
}

然后我得到

未处理的异常：System.Net.WebException：远程服务器返回错误：（401）未经授权。在System.Net.HttpWebRequest.GetResponse（）。

我做错了什么？

我也尝试使用Fiddler发布相同的消息，我得到了

{ “错误”： “INVALID_REQUEST”}

Answer 1

我尝试了您的代码，对我有用的是将request.ContentType = "application/x-www-form-urlencoded";行放在Stream dataStream = request.GetRequestStream();

之前

所以这很有效：

    string postData = "grant_type=authorization_code&redirect_uri=oob&code=nzbcns9";
    ASCIIEncoding encoding = new ASCIIEncoding();
    byte[] byte1 = encoding.GetBytes(postData);
    request.ContentLength = byte1.Length;
    request.ContentType = "application/x-www-form-urlencoded";
    Stream dataStream = request.GetRequestStream();
    dataStream.Write(byte1, 0, byte1.Length);
    dataStream.Close();

这些都不适合我，但是一旦我将SetBasicAuthHeader更改为使用ISO-8859-1编码，它确实有效：

<?php
require("config.php");
$uname =$_POST["uname"];
$pass = $_POST["pass"];
$fname = $_POST["fname"];
$lname = $_POST["lname"];

$insert=$db->prepare("insert into users (uname,pass,fname,lname) values(?,?,?,?)");
$insert->bind_param("ssss",$uname,$pass,$fname,$lname);
if($insert->execute()){
    echo "ok";
}
else
{$db->error;}

?>
