为毕加索设置Cookie

你会想要使用OkHttpDownloader将两者结合在一起:

OkHttpClient client = new OkHttpClient();
CookieManager cookieManager = new CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
client.setCookieHandler(cookieManager);

// Create the downloader for Picasso to use
OkHttpDownloader downloader = new OkHttpDownloader(client);
Picasso picasso = new Picasso.Builder(context).downloader(downloader).build();

覆盖UrlConnectionDownloader的openConnection-Method对我有用.

import android.content.Context;
import android.net.Uri;
import com.squareup.picasso.UrlConnectionDownloader;
import java.io.IOException;
import java.net.HttpURLConnection;

public  class CookieImageDownloader extends UrlConnectionDownloader{

    public CookieImageDownloader(Context context) {
        super(context);
    }

    @Override
    protected HttpURLConnection openConnection(Uri path) throws IOException{
        HttpURLConnection conn = super.openConnection(path);

        String cookieName = /*your cookie-name */;
        String cookieValue = /*your cookie-value */;
        conn.setRequestProperty("Cookie",cookieName + "=" + cookieValue );

        return conn;
    }
}

将其应用于毕加索:

Picasso picasso = new Picasso.Builder(context).downloader(new CookieImageDownloader(context)).build();

并注意不要在picasso.with()事后使用,因为它会再次初始化构建器,删除我们的自定义下载程序CookieImageDownloader,而是picasso.load()直接使用.
