统一说明（重要）
从1.3.3开始，默认开启组(support_group_manage=true)功能（有更好的扩展性）
访问的url中都会带上group的名称，例如：
http://10.1.5.9:8080/这里是组名/upload
如:
http://10.1.5.9:8080/group1/upload
如果（support_group_manage=false）
url变为
http://10.1.5.9:8080/upload
命令上传
curl -F scene=default -F file=@http-index-fs http://10.1.xx.60:8080/group1/upload
说明：其它参数请参考web自带上传面面，文件参数前有个”@” 参数是-F
WEB上传（浏览器打开）
http://yourserver ip:8080/group1/upload.html 注意：不要使用127.0.0.1上传
python版本:
import requests
url = 'http://10.1.5.9:8080/group1/upload'
files = {'file': open('report.xls', 'rb')}
options={'output':'json','path':'','scene':''} #参阅浏览器上传的选项
r = requests.post(url,data=options, files=files)
print(r.text)
golang版本
package main
import (
"fmt"
"github.com/astaxie/beego/httplib"
)
func main() {
var obj interface{}
req:=httplib.Post("http://10.1.5.9:8080/group1/upload")
req.PostFile("file","filename")//注意不是全路径
req.Param("output","json")
req.Param("scene","")
req.Param("path","")
req.ToJSON(&obj)
fmt.Print(obj)
}
java版本
依赖(这里使用了hutool工具包,更简便)
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>4.4.3</version>
</dependency>
上传代码
public static void main(String[] args) {
//文件地址
File file = new File("D:\\git\\2.jpg");
//声明参数集合
HashMap<String, Object> paramMap = new HashMap<>();
//文件
paramMap.put("file", file);
//输出
paramMap.put("output","json");
//自定义路径
paramMap.put("path","image");
//场景
paramMap.put("scene","image");
//上传
String result= HttpUtil.post("http://xxxxx:xxxx/group1/upload", paramMap);
//输出json结果
System.out.println(result);
}
java版本流式上传
Hutool-http、HttpClient、OkHttp3多种方式流式文件上传 由于有不少人问到上面的问题，现在本人总结了一个常用的几种http客户端文件流式上传的方式，相当于给自己做下记录，同时也给有这方面疑问的朋友一个借鉴。废话不多说，直接上代码吧。代码是基于springboot的maven工程。
Hutool-http方式 先在pom中添加hutool的依赖
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>4.5.1</version>
</dependency>
接着在Controller中代码示例
@RequestMapping("/upload")
public String upload(MultipartFile file) {
String result = "";
try {
InputStreamResource isr = new InputStreamResource(file.getInputStream(),
file.getOriginalFilename());
Map<String, Object> params = new HashMap<>();
params.put("file", isr);
params.put("path", "86501729");
params.put("output", "json");
String resp = HttpUtil.post(UPLOAD_PATH, params);
Console.log("resp: {}", resp);
result = resp;
} catch (IOException e) {
e.printStackTrace();
}
return result;
}
HttpClient方式 pom依赖
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
</dependency>
接着在Controller中代码示例
@RequestMapping("/upload1")
public String upload1(MultipartFile file) {
String result = "";
try {
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
CloseableHttpResponse httpResponse = null;
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(200000)
.setSocketTimeout(2000000)
.build();
HttpPost httpPost = new HttpPost(UPLOAD_PATH);
httpPost.setConfig(requestConfig);
MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create()
.setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
.setCharset(Charset.forName("UTF-8"))
.addTextBody("output", "json")
.addBinaryBody("file", file.getInputStream(),
ContentType.DEFAULT_BINARY, file.getOriginalFilename());
httpPost.setEntity(multipartEntityBuilder.build());
httpResponse = httpClient.execute(httpPost);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
String respStr = EntityUtils.toString(httpResponse.getEntity());
System.out.println(respStr);
result = respStr;
}
httpClient.close();
httpResponse.close();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
OkHttp3上传示例 pom文件依赖
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>3.9.1</version>
</dependency>
接着在Controller中代码示例
@RequestMapping("/upload2")
public String upload2(MultipartFile file) {
String result = "";
try {
OkHttpClient httpClient = new OkHttpClient();
MultipartBody multipartBody = new MultipartBody.Builder().
setType(MultipartBody.FORM)
.addFormDataPart("file", file.getOriginalFilename(),
RequestBody.create(MediaType.parse("multipart/form-data;charset=utf-8"),
file.getBytes()))
.addFormDataPart("output", "json")
.build();
Request request = new Request.Builder()
.url(UPLOAD_PATH)
.post(multipartBody)
.build();
Response response = httpClient.newCall(request).execute();
if (response.isSuccessful()) {
ResponseBody body = response.body();
if (body != null) {
result = body.string();
System.out.println(result);
}
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
总结 上面给出了几个示例，是不是都挺简单的？通过这种方式，就可以在Controller中做中转了，还是挺方便的。顺便提一下，上面几种方式中，我个人觉得Hutool的是最简单的，最方便的，对于HttpClient而言，概念比较多，显得相对复杂，OkHttp也一样，不过比HttpClient显得优雅点。针对一般的并发量，个人觉得hutool的Http已经够用了，底层是基于jdk的HttpUrlConnection实现的。如果对性能有特殊要求的，可以考虑httpclient或者OKHttp，后两者相对而言，更推荐使用OkHttp。
