用Httpclient来POST数据，POST不成功

dmcyxsdn 2013-04-11 11:29:29
做的是一个微博的工具，实现登录以及微博发送。

登录已经实现，cookie已经取得。但是发送微博的时候总是返回302 Found 。

POST操作需要发头信息吗？

发微博的代码：
			

	HttpPost postAdd = new HttpPost

		("http://weibo.com/aj/mblog/add?_wv=5&__rnd="+getServerTimeStamp());

	List<NameValuePair> postAddPara = new ArrayList<NameValuePair>();

	postAddPara.add(new BasicNameValuePair("_surl", ""));

	postAddPara.add(new BasicNameValuePair("_t", "0"));

	postAddPara.add(new BasicNameValuePair("hottopicid", ""));

	postAddPara.add(new BasicNameValuePair("location", "home"));

	postAddPara.add(new BasicNameValuePair("module", "stissue"));

	postAddPara.add(new BasicNameValuePair("pic_id", ""));

	postAddPara.add(new BasicNameValuePair("rank", "0"));

	postAddPara.add(new BasicNameValuePair("rankid", ""));

	postAddPara.add(new BasicNameValuePair("text", "战争是个谎言"));

			

	postAdd.setEntity(new UrlEncodedFormEntity(postAddPara, HTTP.UTF_8));

			

	HttpResponse responseAdd = client.execute(postAdd);


祝福你。

14.44 Vary The Vary field value indicates the set of request-header fields that fully determines, while the response is fresh, whether a cache is permitted to use the response to reply to a subsequent request without revalidation. For uncacheable or stale responses, the Vary field value advises the user agent about the criteria that were used to select the representation. A Vary field value of "*" implies that a cache cannot determine from the request headers of a subsequent request whether this response is the appropriate representation. See section 13.6 for use of the Vary header field by caches. Vary = "Vary" ":" ( "*" | 1#field-name ) An HTTP/1.1 server SHOULD include a Vary header field with any cacheable response that is subject to server-driven negotiation. Doing so allows a cache to properly interpret future requests on that resource and informs the user agent about the presence of negotiation on that resource. A server MAY include a Vary header field with a non-cacheable response that is subject to server-driven negotiation, since this might provide the user agent with useful information about the dimensions over which the response varies at the time of the response. A Vary field value consisting of a list of field-names signals that the representation selected for the response is based on a selection algorithm which considers ONLY the listed request-header field values in selecting the most appropriate representation. A cache MAY assume that the same selection will be made for future requests with the same values for the listed field names, for the duration of time for which the response is fresh. The field-names given are not limited to the set of standard request-header fields defined by this specification. Field names are case-insensitive. A Vary field value of "*" signals that unspecified parameters not limited to the request-headers (e.g., the network address of the client), play a role in the selection of the response representation. The "*" value MUST NOT be generated by a proxy server; it may only be generated by an origin server. 我觉得vary不是关键，system busy的提示我倒看到了，还是试试楼上说的抓包比较吧

使用wireshark抓包，比较你的代码发送的请求和微博客户端发送的请求有什么不同。 我想这个不同点就是造成响应代码不同的原因吧！

Vary: Accept-Encoding这个是压缩 你请求头设为application/json看喜爱

上面的太乱了，我把不同的贴出来：

成功返回：
HTTP/1.1 200 OK
DPOOL_HEADER: jason129 失败则是balor154，好像是人名
Content-Length: 3345
Content-Type: application/json; charset=utf-8 失败的type是text/html
返回一个json，在页面显示。

我目前返回：
HTTP/1.1 302 Found
Location: http://weibo.com/sorry?sysbusy
DPOOL_HEADER: balor154
Vary: Accept-Encoding---------------------这个不知道是什么
Content-Length: 0
Content-Type: text/html; charset=utf-8
