nit: maybe call this parameter net_result - it's not always an error.

Well, I've always thought it should have been other way round as long as many
people complained that it should have been DCHECK_NE(net::ERR, net_error);

But as you wish!

[Sergey Ulanov, 2016/09/21 07:13:50]

It matters for EXPECT_EQ/EXPECT_NE from gtest, where the first argument is the
expected value. This is not applicable here.

[Sergey Ulanov, 2016/09/06 17:43:23]

Should we even try reading the response when net_error != OK?

[maksims (do not use this acc), 2016/09/21 05:17:07]

Done.

rename this parameter to result or net_result and then you won't need net_error
below.
