將ESP32——WEB服務(wù)程序測(cè)試項(xiàng)目移植到一個(gè)現(xiàn)有項(xiàng)目中，現(xiàn)有項(xiàng)目包括基于固定IP的WIFI連接、OTA升級(jí)、Websocket等功能。
因模塊采用ESP32-WROVER-E(4MB)，故分區(qū)表內(nèi)容修改如下（后發(fā)現(xiàn)問(wèn)題，下面會(huì)提到）。
# Name, Type, SubType, Offset, Size, Flags nvs, data, nvs, 0x9000, 0x4000 otadata, data, ota, 0xd000, 0x2000 phy_init, data, phy, 0xf000, 0x1000 ota_0, app, ota_0, 0x10000, 1M ota_1, app, ota_1, , 1M www, data, spiffs, , 1M
并修改配置如下圖項(xiàng)。
將restful_server項(xiàng)目front目錄及其下所有內(nèi)容復(fù)制到現(xiàn)有項(xiàng)目根目錄下。
2.3 復(fù)制rest_server.c文件到現(xiàn)有項(xiàng)目main目錄下并在main目錄下CMakeLists.txt文件中添加 "rest_server.c"

config EXAMPLE_MDNS_HOST_NAME
string "mDNS Host Name"

help
Specify the domain name used in the mDNS service.
Note that webpage also take it as a part of URL where it will send GET/POST requests to.
choice EXAMPLE_WEB_DEPLOY_MODE
prompt "Website deploy mode"
default EXAMPLE_WEB_DEPLOY_SEMIHOST
help
Select website deploy mode.
You can deploy website to host, and ESP32 will retrieve them in a semihost way (JTAG is needed).
You can deploy website to SD card or SPI flash, and ESP32 will retrieve them via SDIO/SPI interface.
Detailed operation steps are listed in the example README file.
config EXAMPLE_WEB_DEPLOY_SEMIHOST
bool "Deploy website to host (JTAG is needed)"
help
Deploy website to host.
It is recommended to choose this mode during developing.
config EXAMPLE_WEB_DEPLOY_SD

bool "Deploy website to SD card"
help
Deploy website to SD card.
Choose this production mode if the size of website is too large (bigger than 2MB).
config EXAMPLE_WEB_DEPLOY_SF
bool "Deploy website to SPI Nor Flash"
help
Deploy website to SPI Nor Flash.
Choose this production mode if the size of website is small (less than 2MB).

When using semihost in ESP32, you should specify the host path which will be mounted to VFS.
Note that only absolute path is acceptable.
