dakaz / esp8266-restclient Goto Github PK

Hi,
I'm wondering if server sent events (SSE), will be covered in this repository?
Thanks a lot for your work.

As detailed here: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/src/WiFiClientSecure.h#L27

Hi, i use your library successfully with ESP8266 for some months now...
Recently i had to switch to ESP32 due to performance issues on EpaperDisplays, now in general your library is based on esp8266wifi.h however ESP32 requires wifi.h which seems to be the new naming.....at least for ESP32. So I did change the library include in the header file of your code....no errors.....but also no output when i try to make a get on a restful server....which works well on ESP8266.

Any idea what needs to be considered on top in order to make it work with "wifi.h"?

Highly appreciate your thoughts and check. Regards Norbert

How about this case:

server nginx config

server {
    server_name api.dev;
}

server certificate CN = api.dev or [ext] subjectAltName = DNS:api.dev,DNS:*.api.dev

https://github.com/bscheshirwork/docker-yii2-app-advanced-rbac/blame/api/docs/about-api-ssl.md#L113

connect to server use IP of host machine and verify by hostHeader, not by host

const char* host = "192.168.1.39";
const char* hostHeader = "api.dev";
const int httpsPort = 8082;
String url = "/v1/feedback/create";
// Use web browser to view and copy SHA1 fingerprint of the certificate or use
// openssl x509 -in server.crt -fingerprint 
const char* fingerprint = "A1 1F 18 32 A7 2C CE 2B 74 F8 0E 35 A7 11 16 11 7F 61 22 C9";
...
setup(){
...
  //connect to host
  Serial.print("connecting to ");
  Serial.println((String)host);
  if (!espClient.connect(host, httpsPort)) {
    Serial.println("connection failed");
    return;
  }


  if (espClient.verify(fingerprint, hostHeader)) {
    Serial.println("certificate matches");
  } else {
    Serial.println("certificate doesn't match");
  }
  
  Serial.print("requesting URL: ");
  Serial.println(url);

  espClient.print(String("POST ") + url + " HTTP/1.1\r\n" +
               "Host: " + hostHeader + "\r\n" +
               "User-Agent: MP3ESP8266\r\n" +
               "Connection: close\r\n\r\n");

I think about use your library, but
in this library I can see only equials sslClient.verify(...,host) ; sslClient.connect(host,...)

• Installed latest Arduino IDE 1.8.15 on Windows 10
• Installed latest esp8266 3.0.1 via https://arduino.esp8266.com/stable/package_esp8266com_index.json
• Selected "LOLIN(WEMOS) D1 R2 & mini" board type
• Copied RestClient[.cpp,.h] into examples/simple_POST
• Opened simple_Post.ino and attempted to compile. Generates the following error:

Hi,

I get the following error when using (compiling with) the library:
undefined reference to `RestClient::begin(unsigned char*)

How can I fix it?

The following code put in RestClient constructor will not work (by default all member pointers have undefined values, not NULLs):

if (contentType == NULL) {
  contentType = "application/x-www-form-urlencoded";  // default
}

Working solution would be just getting rid of if clause:

contentType = "application/x-www-form-urlencoded";

Observed on WeMos whild sending POST requests.

Hi,

first, thanks for your work. I have a strange behaviuor using your RestClient library as a pointer.
I define a RestClient object as a pointer, because i need to create it after loading the collector host IP from a config file:

RestClient *restClient;

Later i initialize the object:

      ...
      restClient = new RestClient(config.collector_host); 
      ....

and i send data via POST like:

  char query[128];
  String response="";
  ...
          sprintf(query,"key=%s&ts=%d&t=%s&p=%s&h=%s&uv=%d&pm25=%s&pm10=%s",config.api_key,data.ts,data.temp,data.pres,data.hum,data.uv,data.pm25,data.pm10);
          statusCode = restClient->post("/rest/data/put", query, &response);

but watching data with tcpdump, i see strange behavour in header like:

POST /rest/data/put HTTP/1.1
Host: [host]:80
Connection: close
Content-Length: 36
**Content-Type: L.).**

key=KEY&t=21.60&h=39.80

Any help really appreciated !

RestClient::request() adds a blank line between headers and request body if the method is GET, but this blank line is needed for other methods too, such as POST.
