至于OAuth 是啥，这里不做详细介绍
就是类似这样的东东：
1、先到这边获取Client Id 和 Client Secret ：https://code.google.com/apis/console/b/0/?noredirect
2、创建两个string，储存Client ID 和 Secret
string clientID = "{CLIENT-ID}";
string clientSec = "{CLIENT-SECRET}";
3、Google Code Page 这里有个OAuth2.0 的 .net 版本例子，我们照搬改点东西就好了：
所以我们只要改一改我们的BloggerService 再加上一个function就行了：
先创建NativeApplicationClient
NativeApplicationClient provider = new NativeApplicationClient(GoogleAuthenticationServer.Description)
{
ClientIdentifier = clientID,
ClientSecret = clientSec
};然后是增加一个函数
private static IAuthorizationState getAuth(NativeApplicationClient arg)
{
IAuthorizationState state = new AuthorizationState(new [] {BloggerService.Scopes.Blogger.GetStringValue()})
{
Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl)
};
Uri authUri = arg.RequestUserAuthorization(state);
Process.Start(authUri.ToString());
Console.WriteLine("Please enter auth code:");
string authCode = Console.ReadLine();
return arg.ProcessUserAuthorization(authCode, state);
}创建OAuth2Authenticator
OAuth2Authenticator<NativeApplicationClient> auth = new OAuth2Authenticator<NativeApplicationClient>(provider, getAuth);然后更改BloggerService
BloggerService blogService = new BloggerService(new BaseClientService.Initializer()
{
Authenticator = auth,
ApplicationName = "BloggerTest"
});完整代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Google.Apis.Blogger.v3;
using Google.Apis.Blogger.v3.Data;
using Google.Apis.Services;
using System.Diagnostics;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using DotNetOpenAuth.OAuth2;
using Google.Apis.Util;
namespace BloggerTest
{
class Program
{
static void Main(string[] args)
{
string apiKey= "{API-KEY}";
string blogUrl= "{BLOG-URL}";
string clientID = "{CLIENT_ID}";
string clientSec = "{CLIENT_SECRET}";
NativeApplicationClient provider = new NativeApplicationClient(GoogleAuthenticationServer.Description)
{
ClientIdentifier = clientID,
ClientSecret = clientSec
};
OAuth2Authenticator<NativeApplicationClient> auth = new OAuth2Authenticator<NativeApplicationClient>(provider, getAuth);
BloggerService blogService = new BloggerService(new BaseClientService.Initializer()
{
Authenticator = auth,
ApplicationName = "BloggerTest"
});
BlogsResource.GetByUrlRequest getReq = blogService.Blogs.GetByUrl(blogUrl);
getReq.Key = apiKey;
Blog blog = getReq.Execute();
Console.WriteLine(blog.Id);
Console.ReadKey();
}
private static IAuthorizationState getAuth(NativeApplicationClient arg)
{
IAuthorizationState state = new AuthorizationState(new[] { BloggerService.Scopes.Blogger.GetStringValue() })
{
Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl)
};
Uri authUri = arg.RequestUserAuthorization(state);
Process.Start(authUri.ToString());
Console.WriteLine("Please enter auth code:");
string authCode = Console.ReadLine();
return arg.ProcessUserAuthorization(authCode, state);
}
}
}编译运行后，程序会开启一个页面：
点击Accept
然后就有一长串字符，Copy 了 paste 进程序内 （[教程] 如何在CMD中Copy & Paste）
然后照常输出blog id
PS：Auth code 会过期的！
