转 Android网络编程之使用HttpClient批量上传文件 MultipartEntityBuilder

HttpClient client=new DefaultHttpClient();// 开启一个客户端 HTTP 请求
HttpPost post = new HttpPost(url);//创建 HTTP POST 请求
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
//builder.setCharset(Charset.forName("uft-8"));//设置请求的编码格式
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);//设置浏览器兼容模式
int count=0;
for (File file:files) {
//FileBody fileBody = new FileBody(file);//把文件转换成流对象FileBody
//builder.addPart("file"+count, fileBody);
builder.addBinaryBody("file"+count, file);
count++;
}
builder.addTextBody("method", params.get("method"));//设置请求参数
builder.addTextBody("fileTypes", params.get("fileTypes"));//设置请求参数
HttpEntity entity = builder.build();// 生成 HTTP POST 实体
post.setEntity(entity);//设置请求参数
HttpResponse response = client.execute(post);// 发起请求 并返回请求的响应
if (response.getStatusLine().getStatusCode()==200) {
return true;
}
return false;
