wifi_print(TCP...,string) only works with string allocated to wifi_buffer

[AndyLindsay]

If you try to pass a different string, it is not populated with the response.

Partially addressed with documentation and example code updates in v1.4.88 Update wifi_scan(TCP... docs

Check how common content-length is in headers. If common, then add function to deliver only content.

[AndyLindsay]

Hmmm, this actually looks pretty doable...

A word of caution regarding character sets as it relates to the content-length header. If the character set is multi-byte, such as UTF-8, the value in the content-length will be under reported.

Details can be found here and here.

Got it. Thank you!

This should help: int wifi_getNamedValue(char strSource, char strName, char *fmt, ...);

Usage example on line 102 in Dev branch's Temperature from OpenWeatherMap.

    float temp = 0;
    wifi_getNamedValue(str, "temp", "%f", &temp);
    print("temp = %6.2f deg K\r", temp);
