使用REST或Web服务上传/下载文件 - Upload/Download File using REST or Web Services

是否可以使用REST或任何其他Web服务上传/下载文件并发送HTML代码?

这必须是可能的使用:PHP, Java或ASP

我想这会很有帮助。至少在Java方面是这样。实际上，看一下整个教程

下面是一个如何使用Spring做这件事的例子:

将commons-io和commons-fileupload依赖项添加到pom.xml。在servlet上下文xml文件中配置多部分解析器:

<beans:bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <beans:property name="maxUploadSize" value="10000000" />
</beans:bean>

这将是您的JSP上传文件(即fileUpload.jsp):

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title></title>
</head>
<body>
    <form:form method="post" commandName="upload" action="uploadNewFile"
        enctype="multipart/form-data">
        <table class="table table-bordered">
            <tbody>
                <tr>
                    <td><label>File</label></td>
                    <td><input class="form-control" name="file" type="file"
                        id="file" /></td>
                </tr>
                <tr>
                    <td colspan="2"><input class="btn btn-primary" type="submit"
                        value="Upload" /></td>
                </tr>
            </tbody>
        </table>
    </form:form>
</body>
</html>

这是controller:

import java.io.IOException;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class UploadController {
    // Show page for upload
    @RequestMapping(value = "/fileUpload", method = RequestMethod.GET)
    public ModelAndView showUploadFilePage() {
        return new ModelAndView("fileUpload", "upload", null);
    }
    // Get multipart file and save it
    @RequestMapping(value = "/uploadNewFile", method = RequestMethod.POST)
    public String save(@RequestParam("file") MultipartFile file) {
        // Save it to i.e. database
        // dao.save(file);
        return "fileUpload";
    }
    // Downloads file. I.e. JPG image
    @RequestMapping(value = "/download/{id}", produces = MediaType.IMAGE_JPEG_VALUE)
    public @ResponseBody HttpEntity<byte[]> getFile(
        @PathVariable("id") Integer id) throws IOException {
        byte[] file= dao.get(id).getImage();
        HttpHeaders header = new HttpHeaders();
        header.set("Content-Disposition", "attachment; filename=Image");
        header.setContentLength(file.length);
        return new HttpEntity<byte[]>(file, header);
    }
}

是…其可能的。

这取决于服务器端的实现。

但是如果你只是想要一个答案....它是的

是可能的，需要使用正确的mime类型来实现这一点。

可以在响应体中传递字符串。
