這篇文章介紹了.Net?Core實(shí)現(xiàn)第三方QQ掃碼登錄的方法，文中通過示例代碼介紹的非常詳細(xì)。對大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

效果展示：

核心實(shí)現(xiàn)

展示二維碼

public static (Stream, string) GetLoginQrCode()
{
    var uri = new Uri(QrCodeUrl);
    var request = new HttpRequestMessage(HttpMethod.Get, uri);
    var cookieContainer = new CookieContainer();
    var handler = new HttpClientHandler
    {
        CookieContainer = cookieContainer,
        AllowAutoRedirect = true,
        UseCookies = true
    };
    using var client = new HttpClient(handler);
    var response = client.Send(request);
    var stream = response.Content.ReadAsStreamAsync().Result;
    var cookies = cookieContainer.GetCookies(uri).ToList();
    var qrsig = cookies.FirstOrDefault(x => x.Name == "qrsig")?.Value;
    return (stream, qrsig);
}

解析掃碼結(jié)果

public static (bool, string, ScanResult) GetQqScanResult(string qrsig)
{
    var timeStamp = GetTimeStamp();
    var ptqrToken = ParsePtqrToken(qrsig);
    var uri = new Uri(string.Format(ScanResultUrl, ptqrToken, timeStamp));
    var request = new HttpRequestMessage(HttpMethod.Get, uri);
    var cookieContainer = new CookieContainer();
    cookieContainer.Add(new Cookie("qrsig", qrsig) { Domain = uri.Host });
    var handler = new HttpClientHandler
    {
        CookieContainer = cookieContainer,
        AllowAutoRedirect = true,
        UseCookies = true
    };
    using var client = new HttpClient(handler);
    var response = client.Send(request);
    var content = response.Content.ReadAsStringAsync().Result;
    var result = ParsePtuiCbResult(content);
    return result[0] == "0" ? (true, result[4], new ScanResult(ParseQqNumber(result[2]), result[5])) : (false, result[4], null);
}

登錄視圖

<h1>QQ Scan Login</h1>

<img src="@Url.Action("QrCode")" width="350" alt="二維碼失效？點(diǎn)擊刷新" onclick="javascript:this.src += '?_t='+ Math.random();" style="cursor: pointer;" />

<h1>QQ Scan Result</h1>

<textarea rows="3" cols="45" id="result"></textarea>

<form asp-action="Login" method="post" id="loginForm">
    <input type="hidden" name="nick" id="nickName" />
    <input type="hidden" name="number" id="qqNumber" />
</form>

登錄授權(quán)

配置Cookie認(rèn)證策略

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        // options.Cookie.HttpOnly = true;
        // options.ExpireTimeSpan = TimeSpan.FromHours(2);
        // options.SlidingExpiration = true;

        options.LoginPath = "/Account/Login";
        options.AccessDeniedPath = "/Account/Login";
    });

不要忘記使用策略： app.UseAuthentication();

創(chuàng)建用戶登錄標(biāo)識

if (ModelState.IsValid)
{
    // 創(chuàng)建用戶登錄標(biāo)識，Cookie名稱與IServiceCollection中配置的一樣即可
    var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme);
    // 添加之后，可使用User.Identity.Name獲取該值
    identity.AddClaim(new Claim(ClaimTypes.Name, model.Nick));
    // identity中還可以添加自定義數(shù)據(jù)
    identity.AddClaim(new Claim("qq", model.Number));
    // var customValue = User.Claims.SingleOrDefault(s => s.Type == "qq").Value;
    await HttpContext.SignInAsync(new ClaimsPrincipal(identity));

    return Redirect("~/");
}

用戶退出登錄

await HttpContext.SignOutAsync();
