我正在使用apache HttpClient
将几个文件发布到服务器。这是代码:
public static HttpResponse stringResponsePost(String urlString, String content, byte[] image,
HttpContext localContext, HttpClient httpclient) throws Exception {
URL url = new URL(URLDecoder.decode(urlString, "utf-8"));
URI u = url.toURI();
HttpPost post = new HttpPost();
post.setURI(u);
MultipartEntity reqEntity = new MultipartEntity();
StringBody sb = new StringBody(content, HTTP_CONTENT_TYPE_JSON, Charset.forName("UTF-8"));
ByteArrayBody ib = new ByteArrayBody(image, HTTP_CONTENT_TYPE_JPEG, "image");
reqEntity.addPart("interview_data", sb);
reqEntity.addPart("interview_image", ib);
post.setEntity(reqEntity);
HttpResponse response = null;
response = httpclient.execute(post, localContext);
return response;
}
问题是,
MultipartEntity
类仅具有isChunked()
方法(始终返回false),如果我希望为我的多部分实体启用被阻止的编码,则没有“setChunked(boolean)”选项。我的问题是:
InputStreamEntity
类)具有setChunked(boolean)
而MultipartEntity
没有? 最佳答案
为我的第二个问题找到了解决方案,诀窍是将MultipartEntity
写入ByteArrayOutputStream
,从ByteArrayEntity
创建ByteArrayOutputStream
并在其上启用分块。这是代码:
ByteArrayOutputStream bArrOS = new ByteArrayOutputStream();
// reqEntity is the MultipartEntity instance
reqEntity.writeTo(bArrOS);
bArrOS.flush();
ByteArrayEntity bArrEntity = new ByteArrayEntity(bArrOS.toByteArray());
bArrOS.close();
bArrEntity.setChunked(true);
bArrEntity.setContentEncoding(reqEntity.getContentEncoding());
bArrEntity.setContentType(reqEntity.getContentType());
// Set ByteArrayEntity to HttpPost
post.setEntity(bArrEntity);
