我想POST(在Java中)一个multipart / mixed请求,其中一个部分是’application / json’类型,另一个是’application / pdf’类型.有谁知道一个图书馆,这将允许我轻松地这样做？令人惊讶的是我找不到一个.
我将生成JSON,但我需要能够将该部分的内容类型设置为’application / json’.
非常感谢,

简单,使用Apache Http-client library(此代码使用版本4.1和jars httpclient,httpcore和httpmime),这是一个示例：
package com.officedrop.uploader;
import java.io.File;
import java.net.URL;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.DefaultHttpClient;
public class SampleUploader {
public static void main(String[] args) throws Exception {
DefaultHttpClient httpclient = new DefaultHttpClient();
String basePath = "http://localhost/";
URL url = new URL( basePath );
HttpHost targetHost = new HttpHost( url.getHost(),url.getPort(),url.getProtocol() );
HttpPost httpost = new HttpPost( String.format( "%s%s",basePath,"ze/api/documents.xml"));
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("file_1",new FileBody( new File( "path-to-file.pdf" ),"file.pdf","application/pdf",null));
entity.addPart("uploaded_data_1",new FileBody( new File( "path-to-file.json" ),"file.json","application/json",null));
httpost.setEntity(entity);
HttpResponse response = httpclient.execute( targetHost,httpost);
}
}
