发帖数: 4260 | 1 哪位大峡知道如何在HttpURLConnection里面使用proxy?
我找到的很多sample code 都是用 system property （见下），
但是都不work。里面随便设成bogus ip:port也能拿到page，
说明没有通过proxy出去。
System.setProperty("https.proxyHost", proxyHost);
System.setProperty("https.proxyPort", new
Integer(proxyPort).toString());
有了解的请知会一声，如果找到类似sample code，这个不work :( |

把你要去的ip禁掉，再试试看。

发帖数: 4260 | 3 It falls back to no proxy if proxy server doesn't connect!
But this isn't the behavior I want. Why not leave the logic
to the application. Java tries to be smart where it really
shouldn't :(

How did you make sure that it actually tried the proxy first?
Take a look at httpclient. It has more sophisticated
proxy handling code than the jdk code.

发帖数: 4260 | 5 i'm not so sure. but from the time it uses to connect,
it seems that it didn't fail then try the proxy.
Yeah, I may just use the httpclient lib. I didn't want
to bother with an additional jar - didn't know jvm handles
proxies like this.

The reason I suspect that it's not even trying the proxy
is that it should definitely blow up if the proxy address
isn't correct, instead of falling back _silently_.
