由于"无法使用不可重复的请求实体重试请求",HttpPost失败

Question

我试图通过Android手机中的HttpClient将照片上传到服务器,但有时我得到这个错误,它不会一直发生.谁知道怎么解决呢？

我的代码如下:

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:

这意味着初始请求失败,因为它是一个流,它不能重复它.

如果您删除FileInputStream而使用FileEntity,我相信它将是可重复的.

您也不必设置长度.
