可能这经常是问题,但我无法解决。我需要自动填写从服务器提供的网络表单上的一些字段。我使用 Apache HttpClient 让我的生活更轻松)现在,可以考虑我的步骤来实现目标:
-
1. 我没有 http://trac.edgewall.org/ 的证书,所以我下载了这个软件并在本地安装,完成后我必须创建 NewTicket。
-
2. 我在本地使用没有任何 SSL(SSL 隧道)的 Trac。(将我的程序更改为能够使用 HTTPS 并不难)。
-
3. 到目前为止,我可以认证并执行GET请求,但我不能执行POST请求
-
4. 例如:我对http://localhost:8000/tracenvir/newticket执行 GET 请求。这个(~/newticket)页面如下所示:
http ://s04.radikal.ru/i177/0912/cb/d43971cebc02.png
作为回应,我有:(部分)
-
"输入类型="文本" id="字段摘要" 名称="字段摘要" 大小="70" "
- "textarea id="field-description" name="field_description" class="wikitext" rows="10" cols="68"/textarea"'
- 5. 所以,我写这个:
int status = 0;
int cookLength=0;
Cookie[] cookies = null;
HttpClient client = new HttpClient();
client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
HttpState initialState = new HttpState();
client.setState(initialState);
//**********//
//**Log in**//
//**********//
GetMethod login = new GetMethod("http://localhost:8000/tracenvir/login");
client.getState().setCredentials(AuthScope.ANY,
new UsernamePasswordCredentials("rauch", "qwert"));
login.setDoAuthentication(true);
System.setProperty("javax.net.ssl.trustStore", "/home/rauch/NetBeansProjects/jssecacerts");
try {
status = client.executeMethod(login);
System.out.println("response code = "+status);
cookies = client.getState().getCookies();
cookLength = cookies.length;
for(int i=0;i (less than) cookLength;i++) {
System.out.println(cookies[i].toString());
}
login.releaseConnection();
} catch(IOException ex) {
ex.printStackTrace();
}
//*********************//
//**Create New Ticket**//
//*********************//
PostMethod post = new PostMethod("http://localhost:8000/tracenvir/newticket");
NameValuePair[] data = {
new NameValuePair("field-summary","second error"),
new NameValuePair("field-descryption","Some stupid descryption..."),
new NameValuePair("field-type","defect"),
new NameValuePair("field-priority","major"),
new NameValuePair("field-version","1.0"),
new NameValuePair("field-owner","moscow server"),
new NameValuePair("submit","create ticket"),
};
//post.setRequestBody(data);
post.addParameters(data);
post.addRequestHeader("Referer","http://localhost:8000/tracenvir/login");
for(int i=0;i (less than) cookLength;i++) {
initialState.addCookie(cookies[i]);
}
client.setState(initialState);
try {
status = client.executeMethod(post);
System.out.println("response code = "+status);
byte[] buf = new byte[10];
int r=0;
BufferedInputStream is = new BufferedInputStream(post.getResponseBodyAsStream());
while((r = is.read(buf)) > 0) {
System.out.write(buf, 0, r);
}
post.releaseConnection();
} catch(IOException ex) {
ex.printStackTrace();
}
}
我有这个:
-
400 错误:错误请求
-
缺少或无效的表单令牌。你有启用cookies吗?
怎么了?
- 作为对 GET 请求的响应,我得到以下信息:
- 响应代码 = 200 trac_auth=38144ec2830678183afebf0b14c51721
-
trac_form_token=e9648f17987551b8f97e1953
可能我需要改变这个:
- client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
