我尝试在 android 移动设备中通过 HttpClient 将照片上传到服务器，但有时我会收到此错误，但并非总是如此。任何人都知道如何解决它？

我的代码是这样的:

HttpClient client =new DefaultHttpClient();
HttpPut httpPut = new HttpPut(uploadUrl);       
InputStream in =null;
HttpResponse response =null;
        try {
            in = new FileInputStream(filepath);
            BasicHttpEntity entity = new BasicHttpEntity();
            entity.setContent(in);
            entity.setContentLength(new File(basepath+path).length());

            httpPut.setEntity(entity);
            response = client.execute(httpPut);
            System.out.println(response.getStatusLine());


            consume(response.getEntity());


        } 

.......

错误信息:

最佳答案

这意味着初始请求失败，并且因为它是一个流，所以不能重复它。

如果您删除 FileInputStream 并改为使用 FileEntity , 我相信它将是可重复的。

您也不必设置长度。
