The hardware supporting software was developed by c. Now c needs to send data to PHP through the 3G module. The data includes ordinary strings and image files.
I don’t know why the data array sent to me by c only has a pair of key values. The value is a string composed of all the data separated by English commas...
I didn’t care at first, I split it myself Dividing strings into arrays for processing can be done correctly.
But the image is a file and cannot be spliced ​​into a string.
c Just convert the picture into a binary string, use the same method to splice it with other data into a string and send it to me, and let me convert the binary string into a picture, but at this time I don’t know what to do I can't even receive it...
I don't understand c, and development can no longer proceed... Is this the right approach? Which side is the problem? What should be done correctly? Grateful

大家讲道理

There is a problem with the way the question is asked, and it has nothing to do with cross-domain.
I provide two solutions
1. C++ calls the file upload interface of PHP, similar to the form upload file
2. The image is encoded in base64, and C++ passes the encoded string to you, and you can also parse it


3. You said you did not receive the content. You need to confirm this first. Either c++ failed or you did not receive it.
Whether it can be restored to an image through a binary string is a problem. No binary characters were received. Strings are another problem

小葫芦

It’s not a browser, there is no cross-domain problem.
This depends on the specific request protocol, such as:HTTP啥的,php接收图片也是用二进制啊Content-Type:multipart/form-data;
