给出调用代码, 看上去是req.getHeader()返回null导致NPE

@wendal
Properties prop = new Properties();
InputStream in = GuoDuSMSClient.class.getClassLoader().getResourceAsStream("custom/proxy.properties");
try {
prop.load(in);
} catch (IOException e) {
try {
in.close();
} catch (IOException e1) {
e1.printStackTrace();
}
}
Http.setHttpProxy(prop.getProperty("proxy.host"),Integer.parseInt(prop.getProperty("proxy.port")));
Http.setAutoSwitch(true);
//...
Http.post2(url, params, timeOut);

知道了,是bug, 先用post3, header传Header.create()

https://github.com/nutzam/nutz/issues/1126 已fix

@wendal
post3 body直接把参数map传进去就行吧？
Http.post3(address, params, Header.create(), Constant.SMS_TIME_OUT);

这样写吧.

return Sender.create(Request.create(url, METHOD.POST, params, Header.create()))
                     .setTimeout(timeout)
                     .send();

@wendal setHttpProxy是一次设置任何地方调用Http.post/get ...都会经过代理吗

@ysysdzz 是的

@wendal 那如果。。。想只在一个地方使用代理。。请求结束后，setHttpProxy(null,null)?

Http.setProxySwitcher 看看这个方法, 自定义规则都行
