如果有人想要调用API,则需要在请求中删除.csv,如下所示:
byte sd = stash.create();
stash.print("variable="); //change this to your post variable
stash.print(VARIABLE);
stash.print("&action=Submit");
stash.save();
// generate the header with payload - note that the stash size is used,
// and that a "stash descriptor" is passed in as argument using "$H"
//remove the .csv
Stash::prepare(PSTR("POST http://$F/$F HTTP/1.0" "\r\n"
"Host: $F" "\r\n"
"Content-Length: $D" "\r\n"
"Content-Type: application/x-www-form-urlencoded" "\r\n"
"\r\n"
"$H"),
website, PSTR(PATH), website, stash.size(), sd);

首先,您需要安装以下库:https://github.com/jcw/ethercard
用6个引脚将模块连接到arduino:
ENC SO - > Arduino引脚12
ENC SI - > Arduino引脚11
ENC SCK - > Arduino引脚13
ENC CS - > Arduino引脚8
ENC VCC - > Arduino 3V3引脚
ENC GND - > Arduino Gnd引脚
然后使用以下代码:
您可能想要尝试这个与库存Ethernet-lib完全兼容的库:
https://github.com/ntruchsess/arduino_uip
来自Arduino-IDE以太网的示例通过在[arduino-dir] / libraries / UIPEthernet中安装此lib来打开标准以太网示例(例如:examples-> Ethernet-> WebServer)并将“Ethenet.h”替换为“ UIPEthernet.h” .
关于netheads回答,我在服务器端收到POST数据时遇到问题 . 它正在接收 Headers 信息,我无法使用$ _POST或任何其他方式访问帖子数据 . 我发现指定内容类型解决了这个问题 . 只需更改HTTP标头部分,如下所示:
Arduino v1.6.12
如果有人想要调用API,则需要在请求中删除.csv,如下所示:
其他信息,如果您使用本地服务器进行测试,则可以查看Wampp或Xampp Server的访问日志,以了解您的请求已到达服务器的天气 .
并在此行中使用const:
