I want to ask. In general, how does one get an image through a url? The company's ios said that he could only encapsulate the image into a data stream, and then pass it through the parameter. then the parameter is too long to pass. I would like to ask, is this my technical problem? it is very hard. I am a fresh graduate. I have never heard of using gey for four years at school. is my experience too short? I mean I can't do anything. if you think I'm here to spray ios, just spray me. By the way, please get me and ask. In general, how does one get an image through a url?

I said I couldn't do anything. if you think I'm here to spray ios, I 'd like to try it out. By the way, I 'd like to find a get solution. thank you.
------ Solution --------------------
I have never heard of it. wait for the ox to get up to 1024 bytes and wait for the ox to solve it.
------ Solution --------------------
I have never performed IOS, but I guess it is not through get.

Reference: php: // input

Is post okay?
A lot of off-the-shelf code on the Internet
