如何修复不返回的Java http多部分文件上传？

问题描述

我正在尝试使用

上传文件

这适用于大多数文件，但对于某些文件似乎失败了：文件已上传（我可以在服务器上看到它并且它与源文件的大小相同）。但是，一旦文件上传，client.execute(post) 调用就永远不会返回。失败的文件似乎是较大的文件（> 800M）。

代码如下所示。

import java.io.File;
import java.io.FileInputStream;

import org.apache.commons.io.IoUtils;
import org.apache.http.httpentity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
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.entity.mime.content.StringBody;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;

import lombok.extern.slf4j.Slf4j;

@Slf4j
public class HttpFileUpload2 {

    public static void main(String args[]) throws Exception {
        log.info("Starting...");
        String url = "https://url-of-the-rest-api/api/2.0/dbfs/put";
        String token = "security-token";
        String path = "/path/on/the/server/for/myfile.txt";
        String srcFile = "C:\\path\\to\\myfile.txt";

        File file = new File(srcFile);
        HttpPost post = new HttpPost(url);
        //
        multipartentityBuilder builder = multipartentityBuilder.create();
        builder.setMode(HttpMultipartMode.broWSER_COMPATIBLE);
        builder.addTextBody("path",path,ContentType.TEXT_PLAIN);
        log.info("Converting to byte[]...");
        byte[] bytes = IoUtils.toByteArray(new FileInputStream(file));
        log.info("Adding to builder");
        builder.addBinaryBody("upload-file",bytes,ContentType.APPLICATION_OCTET_STREAM,file.getName());
        
        httpentity entity = builder.build();
        //
        post.setEntity(entity);
        post.addHeader("Authorization","Bearer " + token);
        CloseableHttpClient client = HttpClients.createDefault();
        log.info("Doing post...");
        HttpResponse httpResponse = client.execute(post);
        String response = HttpRequestClient.getResponse(httpResponse.getEntity().getContent());
        // we never get to this line
        log.info("Got response: \n" + response);
        log.info("Done.");
    }

}
