我有一个类将从https服务器下载文件.当我运行它时,它会返回很多错误.我的证书似乎有问题.是否可以忽略客户端 - 服务器身份验证？如果是这样,怎么样？

package com.da;

import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.CharBuffer;
import java.util.concurrent.Future;

import org.apache.http.HttpResponse;

public class RSDDownloadFile {
    static FileOutputStream fos;

    public void DownloadFile(String URI, String Request) throws Exception
    {
        java.net.URI uri = URIUtils.createURI("https", "176.66.3.69:6443", -1, "download.aspx",
                "Lang=EN&AuthToken=package", null);
        System.out.println("URI Query: " + uri.toString());

        HttpAsyncClient httpclient = new DefaultHttpAsyncClient();
        httpclient.start();
        try {
            Future<Boolean> future = httpclient.execute(
                    new HttpAsyncGet(uri),
                    new ResponseCallback(), null);

            Boolean result …

我正在尝试使用Boost Asio创建一个HTTP客户端.我从asio复制了同步客户端示例,编译然后运行.不幸的是,在我的日志中,它显示找不到服务.当我跟踪代码时,我发现它是从以下代码抛出的:

boost::asio::io_service io_service;
// Get a list of endpoints corresponding to the server name.
tcp::resolver resolver(io_service);
//->if i removed the http, it has no error
tcp::resolver::query query("host.com", "http");
//->This part throws the service not found
tcp::resolver::iterator endpoint_iterator = resolver.resolve(query);
tcp::resolver::iterator end;

任何人都可以解释为什么抛出未找到的服务或者如何解决这个问题？

我正在使用CABasicAnimation旋转CALayer并且工作正常.问题是,当我尝试旋转同一层时,它会在旋转之前返回到原始位置.我的预期输出是,对于下一轮,它应该从它结束的地方开始.这是我的代码:

CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
animation.fromValue         = 0;
animation.toValue           = [NSNumber numberWithFloat:3.0];
animation.duration          = 3.0;
animation.timingFunction    = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
animation.removedOnCompletion = NO;
animation.fillMode          = kCAFillModeForwards;
animation.autoreverses      = NO;
[calayer addAnimation:animation forKey:@"rotate"];

我的代码上有什么遗漏？谢谢

我这里有一个使用Magick ++(ImageMagick接口)库的简单图像转换器代码.(Eclipse IDE)

#include <Magick++.h>
#include <string>
#include <iostream>

using namespace std;

using namespace Magick;

int main(int argc,char **argv) 
{ 
    Image image; 
    image.read("/home/usr1/test.tiff");
    image.write( "/home/usr1/test.bmp" ); 
    return 0;
}

我正在使用arm-linux目标进行交叉编译.代码编译成功,但在链接部分,我得到了未定义的引用错误.
