使用Java HttpClient将文件上载到apache web服务器

1 年，4 月 Questions & Answers 42

我正在尝试使用Java HttpClient和本地apache web服务器将文件上载到web服务器。对于apache web服务器，我创建了一个虚拟主机，并将其文件夹的完全权限授予了我的ubuntu用户名（而不是根用户）。我加了一个标志。png文件位于我的项目文件夹的根目录下，但在我的apache虚拟主机的文件夹中没有记录任何内容

当运行主（也是唯一）java类时，我总是得到这个返回答案，RequestBuilder指向http://localhost:

<html>
    <head>
        <title>Welcome to test upload!</title>
    </head>
    <body>
        <h1>Success!  The test upload virtual host is working!</h1>
    </body>
</html>

HTTP/1.1 200 OK

如果我改变主意http://localhost到http://localhost/tester（tester是一个新文件夹），我得到了这个答案，但tester文件夹中没有任何记录：

<html><head>
<title>301 Moved Permanently</title>
</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a href="http://localhost/tester/">here</a>.</p>
<hr>
<address>Apache/2.4.41 (Ubuntu) Server at localhost Port 80</address>
</body></html>

HTTP/1.1 301 Moved Permanently

我基本上复制粘贴了这个tutorial的代码

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.client.methods.RequestBuilder;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;

public class MultipartUploadExample {

    public static void main(String args[]) throws Exception{

        //Creating CloseableHttpClient object
        CloseableHttpClient httpclient = HttpClients.createDefault();

        //Creating a file object
        File file = new File("sample.txt");

        //Creating the FileBody object
        FileBody filebody = new FileBody(file, ContentType.DEFAULT_BINARY);

        //Creating the MultipartEntityBuilder
        MultipartEntityBuilder entitybuilder = MultipartEntityBuilder.create();

        //Setting the mode
        entitybuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

        //Adding text
        entitybuilder.addTextBody("sample_text", "This is the text part of our file");

        //Adding a file
        entitybuilder.addBinaryBody("image", new File("logo.png"));

        //Building a single entity using the parts
        HttpEntity mutiPartHttpEntity = entitybuilder.build();

        //Building the RequestBuilder request object
        RequestBuilder reqbuilder = RequestBuilder.post("http://localhost");

        //Set the entity object to the RequestBuilder
        reqbuilder.setEntity(mutiPartHttpEntity);

        //Building the request
        HttpUriRequest multipartRequest = reqbuilder.build();

        //Executing the request
        HttpResponse httpresponse = httpclient.execute(multipartRequest);

        //Printing the status and the contents of the response
        System.out.println(EntityUtils.toString(httpresponse.getEntity()));
        System.out.println(httpresponse.getStatusLine());
    }
}
