Okhttp3上传参数、文件和同时上传

OkHttpClient client=new OkHttpClient();

//一种：参数请求体
FormBody paramsBody=new FormBody.Builder()
.add(“id”,currentPlan.getPlanId()+"")
.add(“name”,currentPlan.getName())
.add(“volume”,currentPlan.getVolume())
.add(“type”,currentPlan.getType()+"")
.add(“mode”,currentPlan.getMode()+"")
.build();

//二种：文件请求体
MediaType type=MediaType.parse(“application/octet-stream”);//“text/xml;charset=utf-8”
File file=new File("/data/data/com.example.company/files/plan/plans.xml");
RequestBody fileBody=RequestBody.create(type,file);

//三种：混合参数和文件请求
RequestBody multipartBody = new MultipartBody.Builder()
.setType(MultipartBody.ALTERNATIVE)

	//一样的效果
        .addPart(Headers.of(
            "Content-Disposition",
            "form-data; name=\"params\"")

            "form-data; name=\"file\"; filename=\"plans.xml\"")
