从网址读取图片 [英] read image from url
问题描述
有没有人能指出一个可以从
网址读取图像到内存的库？在Java中这很容易，但是用c / c ++很难找到一个完整的
解决方案。
谢谢，
Hi, can anyone point me a library that can read image to memory from a
URL? It is very easy in Java, but it is hard to find an complete
solution in c/c++.
Thanks,

也许是因为神秘的语言C / C ++没有退出？
你必须用自己喜欢的语言找到自己的HTTP库。

Maybe because the mythical language of C/C++ doesn''t exit?
You will have to find yourself an HTTP library in your preferred language.

也许是因为C / C ++的神话语言不退出？

连续5个字符C / C ++，指的是C或C ++。
如果我要编写一个没有使用C ++提供的扩展功能的程序，那么我称之为C程序。

如果你追求多功能性，那么拥有C代码比使用C ++代码更好。

The 5 consecutive characters, "C/C++", refer to "C or C++".
If I were to write a program which didn''t use the extended features which
C++ provides over C, then I''d call it a C program.
Makes me think of how race car manufacturers try to get a "road
worthiness stamp" for their race vehicles; these vehicles are primarily
race vehicles, not road vehicles, but if they can get a road-worthiness
stamp for it aswell, then that''s great!
If you start off writing a program with no intention of prohibiting
yourself from using C++ features, and still end up with a finished
product which doesn''t use C++ features, then it''s quite like setting out
to design a race car, and ending up with a car that''s also road-worthy.
I compare the ability to "compile as C" with a "road worthiness stamp" --
it''s the icing on the cake!
I *never* hesitate to use C++ features, (and I actually use them quite
often), but if I did some day produce a program which didn''t use any C++
features at all, I''d consider going back through it and changing
everything to C.
If you''re after versatility, it''s better to have C code than C++ code.
