Convert image to string without losing data in c++
Convert image to string without losing data in c++
I am sending data from my C++ client to C# WCF service where it accepts JSON data.
We need to send an image to WCF service by converting it to a JSON string, but while converting image (jpg/jpeg) it has some null characters inside a string () so the string is getting terminated when converting std::string to char* and I am able to send only part of the string to service. Is there way that I can convert the image to string (const char *) without having null characters in it so that I can send all the image data (as char*) without loosing any data?
std::string
char*
const char *
char*
The available function from C++ client is:
httpClient.POST("ServiceName", const char* data, "ContentType")
You should not create a "string" from the raw binary data. Instead you use some encoding scheme that is textual but can handle arbitrary binary data. One such common encoding scheme is base64.

Convert the data to hex or base64 first.
