Java使用 OkHttpClient 模拟表单提交请求

使用 OkHttpClient 模拟表单提交请求，普通字段加文件上传

一、maven依赖

      <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
            <version>3.14.2</version>
      </dependency>

二、请求代码 

 public static void uploadFile(String url, byte[] file,String other) {

        OkHttpClient client = new OkHttpClient();
        RequestBody fileBody = RequestBody.create(MediaType.parse("video/mp4"), file);//将file转换成RequestBody文件 这里以MP4视频为例
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("其他参数字段名", 其他参数值)
                .addFormDataPart("文件参数字段名", 文件名, fileBody)
                .build();
        
        Request request = new Request.Builder()
                .url(url)
                .post(requestBody)
                .build();
        try {
            Response response = client.newCall(request).execute();
            int code = response.code();
            if(code==200){
                log.info("上传成功");
            }else {
                log.info("上传出错 {}",response.body().string());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
