HttpClient Example Issues

Getting Started

I am trying to get the HttpClient example working with the www.timeapi.org website to tell me the time, but I only keep getting this response from the serial port.

This is the code I am using.

#include "application.h"
#include "HttpClient/HttpClient.h"

/**
* Declaring the variables.
*/
unsigned int nextTime = 0;    // Next time to contact the server
HttpClient http;

// Headers currently need to be set at init, useful for API keys etc.
http_header_t headers[] = {
    //  { "Content-Type", "application/json" },
    //  { "Accept" , "application/json" },
    { "Accept" , "*/*"},
    { NULL, NULL } // NOTE: Always terminate headers will NULL
};

http_request_t request;
http_response_t response;

void setup() {
    Serial.begin(9600);
}

void loop() {
    if (nextTime > millis()) {
        return;
    }

    Serial.println();
    Serial.println("Application>\tStart of Loop.");
    // Request path and body can be set at runtime or at setup.
    request.hostname = "www.timeapi.org";
    request.port = 80;
    request.path = "/utc/now";

    // The library also supports sending a body with your request:
    //request.body = "{\"key\":\"value\"}";

    // Get request
    http.get(request, response, headers);
    Serial.print("Application>\tResponse status: ");
    Serial.println(response.status);

    Serial.print("Application>\tHTTP Response Body: ");
    Serial.println(response.body);

    nextTime = millis() + 10000;
}

Can anyone help me out?

I’ve edited your post to properly format the code. Please check out this post, so you know how to do this yourself in the future. Thanks in advance! ~Jordy

I am having the same issue.

I tried another website and it ended up working, so try to find another website and see if that solves your issue.

I just did some experimenting, and determined that this site (for whatever reason) will only accept a request that includes a “User-agent” header in the request. Try adding that in your code, and it should work.

http_header_t headers[] = {
    //  { "Content-Type", "application/json" },
    //  { "Accept" , "application/json" },
    { "Accept" , "*/*"},
    { "User-agent", "Particle HttpClient"},
    { NULL, NULL } // NOTE: Always terminate headers will NULL
};
