javapost模擬

『壹』 java POST xml請求

是的，就是將你的xml文本內容寫出去就好了，接收端接收到後解析xml 以取得參數名及值

『貳』 java模擬post 出現「可能訪問過於頻繁或非正常訪問」

應該是有限制，把你的post請求，加上瀏覽器代理信息等，盡量看起來更像一個瀏覽器發起的正常請求。

『叄』 怎麼使用java模擬post請求

你要導入httpclient的jar包，要是你請求參數格式是json的或者返回的是json格式數據，你還需要導入json包
/**
* post請求
* @param url url地址
* @param jsonParam 參數
* @param noNeedResponse 不需要返回結果
* @return
*/
public static JSONObject httpPost(String url,JSONObject jsonParam, boolean noNeedResponse){
//post請求返回結果
DefaultHttpClient httpClient = new DefaultHttpClient();
JSONObject jsonResult = null;

『肆』 如何使用java模擬post請求

有很多工具可以實現，比如使用HTTPclient工具去模擬post請求

『伍』 要求將資料庫中獲取的一條數據上報成功，用java模擬 post請求求大神給點例子啊或者思路啊。解決必採納

import org.apache.commons.httpclient.methods.PostMethod;
String url="";

PostMethod pm = new PostMethod(url);
pm.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=GBK");
pm.setRequestHeader(....);
.....//設置請亮野纖求頭信息
pm.addParameter(String,Object);
....//設置參數

this.executeMethod(pm);//發送請求敬仿

String rt = toString(pm.getResponseBodyAsStream(),"脊猜GBK");//解析響應

『陸』 關於JAVA模擬發送post請求並響應內容

如果你是用java的api實現的模擬post請求，那麼你需要在你之前構造的http request的header里加上
Cookie：名字=值 然後統一包裝成你的conenction的OutputStream。
建議你用apache的HttpClient api項目，裡面有專門處理cookie的api，這樣事情就簡單許多。

『柒』 如何使用java模擬post請求

兩種選擇：一、使用httpclient，二使用java自帶的類庫。
1、java自帶類庫：

public static String call(String address,String params) {

URL url = null;

HttpURLConnection httpurlconnection = null;

StringBuilder result = new StringBuilder();

try {

url = new URL(address);

// 以post方式請求

httpurlconnection = (HttpURLConnection) url.openConnection();

httpurlconnection.setDoOutput(true);

httpurlconnection.setRequestMethod("POST");

if(null!=params&¶ms.length()>0){

httpurlconnection.getOutputStream().write(params.getBytes());

httpurlconnection.getOutputStream().flush();

httpurlconnection.getOutputStream().close();

}

// 獲取頁面內容

java.io.InputStream in = httpurlconnection.getInputStream();

java.io.BufferedReader breader = new BufferedReader(new InputStreamReader(in, Config.DEFAULT_CHARSET));

String str = breader.readLine();

while (str != null) {

result.append(str);

str = breader.readLine();

}

breader.close();

in.close();

} catch (Exception e) {

} finally {

if (httpurlconnection != null)

httpurlconnection.disconnect();

}

return result.toString().trim();

}

2、httpclient：

public static String post(String url,String params){
HttpClient httpClient = new DefaultHttpClient();

StringBuilder builder = new StringBuilder();

HttpPost post = new HttpPost(url);

try {

if(null!=params){

post.setEntity(new StringEntity(params,"UTF-8"));

}

HttpResponse resp = httpClient.execute(post);

int statusCode = resp.getStatusLine().getStatusCode();

if(statusCode<=304){

HttpEntity entity = resp.getEntity();

if (entity == null) {

throw new IllegalArgumentException("HTTP entity may not be null");

}

if (entity.getContentLength() > Integer.MAX_VALUE) {

throw new IllegalArgumentException("HTTP entity too large to be buffered in memory");

}

int i = (int)entity.getContentLength();

i = i<0 ? 4096 : i;

final InputStream instream = entity.getContent();

final Reader reader = new InputStreamReader(instream, Config.DEFAULT_CHARSET);

final CharArrayBuffer buffer = new CharArrayBuffer(i);

final char[] tmp = new char[1024];

int l;

while((l = reader.read(tmp)) != -1) {

buffer.append(tmp, 0, l);

}

builder.append(buffer);

}

post.abort();

} catch (Exception e) {

post.abort();

}

return builder.toString().trim();

}

『捌』 java怎麼模擬post提交

String action = "xxxxxxxxxxx"；
URL url = new URL(action);
HttpURLConnection http = (HttpURLConnection) url.openConnection();
http.setRequestMethod("POST");
http.setConnectTimeout(0);
http.setInstanceFollowRedirects(true);
http.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
http.setDefaultUseCaches(false);
http.setDoOutput(true);

String queryString = "";
PrintWriter out = new PrintWriter(http.getOutputStream());
out.print(queryString);//傳入參數
out.close();
http.connect();//連接
InputStream in = httpURLConnection.getInputStream();//返迴流
其他的自己來了吧

『玖』 java 模擬post登錄

這個要分兩步，先用GET方法取得頁面源碼，分析出mpc的值，然後用POST方法發送數據就能登錄了。當然一切工作之前要設置好CookieHandler

post頁面：
http://www.songtaste.com/info_oper.php?tag=signin&pageref=

post參數就4個而已，
name=yourName&pwd=yourPassword&B12=Login&mpc=分析得到的mpc

看如下例子：
http://..com/question/141336096.html
將這個例子中的如下語句改一下就能收到數據的
connection.getInputStream().close();
