這段代碼非常令人困惑.流程不合邏輯,異常處理很糟糕.像if(p！= path)和if(cookys！= cookies)之類的對象引用比較沒有任何意義.要比較對象的內(nèi)容,您需要使用equals()方法.

到目前為止,我知道您希望在同一個域上的一堆后續(xù)Jsoup請求中維護(hù)cookie.在這種情況下,您需要基本遵循以下流程：

Map cookies = new HashMap();

// First request.

Connection connection1 = Jsoup.connect(url1);

for (Entry cookie : cookies.entrySet()) {

connection1.cookie(cookie.getKey(), cookie.getValue());

}

Response response1 = connection1.execute();

cookies.putAll(response1.cookies());

Document document1 = response1.parse();

// ...

// Second request.

Connection connection2 = Jsoup.connect(url2);

for (Entry cookie : cookies.entrySet()) {

connection2.cookie(cookie.getKey(), cookie.getValue());

}

Response response2 = connection2.execute();

cookies.putAll(response2.cookies());

Document document2 = response2.parse();

// ...

// Third request.

Connection connection3 = Jsoup.connect(url3);

for (Entry cookie : cookies.entrySet()) {

connection3.cookie(cookie.getKey(), cookie.getValue());

}

Response response3 = connection3.execute();

cookies.putAll(response3.cookies());

Document document3 = response3.parse();

// ...

// Etc.

這可以重構(gòu)為以下方法：

private Map cookies = new HashMap();

public Document get(url) throws IOException {

Connection connection = Jsoup.connect(url);

for (Entry cookie : cookies.entrySet()) {

connection.cookie(cookie.getKey(), cookie.getValue());

}

Response response = connection.execute();

cookies.putAll(response.cookies());

return response.parse();

}

可以用作

YourJsoupWrapper jsoupWrapper = new YourJsoupWrapper();

Document document1 = jsoupWrapper.get(url1);

// ...

Document document2 = jsoupWrapper.get(url2);

// ...

Document document3 = jsoupWrapper.get(url3);

// ...

請注意,即將推出的Jsoup 1.6.2將附帶一個新的Connection#cookies(Map)方法,該方法應(yīng)該使循環(huán)每次都是多余的.
