1.使用 AddPart 方法
public static void upload(String authorization,String baseUrl,String filePath,String userId,String isOverWrite,String remotePath){
??CloseableHttpClient client = HttpClients.createDefault();
??String uploadFile_url = Utils.getValue("uploadFile.url");
??String url=baseUrl+uploadFile_url;
??HttpPost post = new HttpPost(url);
??System.out.println("---->upload_url:"+url);
??//设置请求头
??HashMap<String, String> header = new HashMap<>();
??header.put("Authorization", authorization);//Basic YWRtaW4xMjM6MTIzcXdl
??Iterator<String> iterator_header = header.keySet().iterator();
??while(iterator_header.hasNext()){
?????String key = iterator_header.next();
?????post.addHeader(key,header.get(key));
??}
??//构造待上传数据,加入builder
??File file=new File(filePath);
??String fimeName = file.getName();
??MultipartEntityBuilder builder = MultipartEntityBuilder.create();
??builder.setMode(HttpMultipartMode.RFC6532);
??builder.setCharset(Charset.forName("UTF-8"));
??builder.addPart("userId", new StringBody(userId, ContentType.MULTIPART_FORM_DATA));
??builder.addPart("remotePath", new StringBody(remotePath, ContentType.MULTIPART_FORM_DATA));
??builder.addPart("isOverWrite", new StringBody(isOverWrite, ContentType.MULTIPART_FORM_DATA));
??builder.addPart("isSendEmail", new StringBody(String.valueOf(false), ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowChunkNumber", new StringBody("1", ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowChunkSize", new StringBody("104857600", ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowCurrentChunkSize", new StringBody("90058", ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowTotalSize", new StringBody("90058", ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowIdentifier", new StringBody("90058-2pdf", ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowFilename", new StringBody(fimeName, ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowRelativePath", new StringBody(fimeName, ContentType.MULTIPART_FORM_DATA));
??builder.addPart("flowTotalChunks", new StringBody("1", ContentType.MULTIPART_FORM_DATA));
??builder.addPart("file", new FileBody(file, ContentType.DEFAULT_BINARY));
??HttpEntity entity = builder.build();
??post.setEntity(entity);
??HttpResponse response = null;
??try {
?????response = client.execute(post);
?????System.out.println("---->reponse:"+response);
?????entity = response.getEntity();
?????JSONObject result = JSONObject.parseObject(EntityUtils.toString(entity));
??} catch (IOException e) {
?????e.printStackTrace();
??}
}
2.使用 addTextBody 方法
?public static void uploadInterface(String authorization,String baseUrl,String filePath,String userId,String isOverWrite,String remotePath){
?????CloseableHttpClient client = HttpClients.createDefault();
String uploadFile_url = Utils.getValue("uploadFile.url");
String url=baseUrl+uploadFile_url;
?????HttpPost httpPost=new HttpPost(url);//通过post传递 ?
?????
//heard处理
?????HashMap<String, String> header = new HashMap<>();
header.put("Authorization", authorization);//
?????Iterator<String> iterator_header = header.keySet().iterator();
?????while(iterator_header.hasNext()){
??????String key = iterator_header.next();
??????httpPost.addHeader(key,header.get(key));
?????}
?????File file=new File(filePath);
?????String ?fileName=file.getName();
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
?? builder.addTextBody("userId", userId,ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("remotePath", "/",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("isOverWrite", "-1",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("isSendEmail", String.valueOf(false),ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowChunkNumber", "1",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowChunkSize", "104857600",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowCurrentChunkSize", "3493921",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowTotalSize", "3493921",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowIdentifier", "3493921-1jpg",ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowFilename", fileName,ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowRelativePath", fileName,ContentType.TEXT_PLAIN.withCharset("UTF-8"))
?????.addTextBody("flowTotalChunks", "1",ContentType.TEXT_PLAIN.withCharset("UTF-8"));
? builder.addBinaryBody("file", file, ContentType.create("image/jpeg"), fileName);
?????HttpEntity entity = builder.build();
?????httpPost.setEntity(entity); ?
?????
?????/**发送请求*/ ?
?????try { ?
??????String result="";
?????????HttpResponse response=client.execute(httpPost); ?
?????????HttpEntity responseEntity = response.getEntity();
?????????if (responseEntity != null) {
?????????????// 将响应内容转换为字符串
?????????????result = EntityUtils.toString(responseEntity, Charset.forName("UTF-8"));
?????????}
?????????//判断是否上传成功 ?返回200 ?
?????????if (response.getStatusLine().getStatusCode()== HttpStatus.SC_OK){ ?
?????????} ?
?????} catch (ClientProtocolException e){ ?
?????????e.printStackTrace(); ?
?????} catch (IOException e) { ?
?????????e.printStackTrace(); ?
?????} ?
?}
3.addBinaryBody中文文件乱码解决方法ContentType contentType = ContentType.create("text/plain",Charset.forName("UTF-8"));
HttpEntity caiJiEntity= MultipartEntityBuilder.create()
.addBinaryBody("file", new File("d://2.mp4"), ContentType.create("video/mp4"), "2.mp4")
.addBinaryBody("file1",new File("d:/1-120915094151.jpg"),
ContentType.create("image/jpg"), "1-120915094151.jpg")
.addTextBody("mtxs", "三面立柱",contentType)
.build();
使用 HttpClient ?进行文件上传
