我尝试使用HttpClient 4.3.3和multipartentityBuilder上传文件时实现进度
所以实际上我用以下代码执行一个post请求
HttpClientBuilder builder = HttpClientBuilder.create();
HttpClient httpClient = builder.build();
HttpPost httpPost = new HttpPost(uploadUrl);
multipartentityBuilder entityBuilder = multipartentityBuilder.create();
entityBuilder.addPart("filea",new FileBody(filea));
entityBuilder.addPart("fileb",new FileBody(fileb));
final httpentity entity = entityBuilder.build();
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
知道如何从上传中获得实际进展吗？我搜索了很多 – 但是这些例子是针对android而不是简单的java或者旧版本的HttpClient而且对我来说不起作用……
解决方法
我刚刚找到了解决方案：
您需要一个httpentityWrapper来计算已处理的字节并进行回调.
ProgresshttpentityWrapper.ProgressCallback progressCallback = new ProgresshttpentityWrapper.ProgressCallback() {
@Override
public void progress(float progress) {
//Use the progress
}
}
httpPost.setEntity(new ProgresshttpentityWrapper(entityBuilder.build(),progressCallback));
这是ProgresshttpentityWrapper：https://github.com/x2on/gradle-hockeyapp-plugin/blob/master/src/main/groovy/de/felixschulze/gradle/util/ProgressHttpEntityWrapper.groovy的完整代码
