I have a program that periodically calls http.get. Generally it works fine and the response.status is 200 but occasionally it returns -1. AFAIK, -1 is not a standard HTTP result code. Can someone tell me what that’s all about? Thanks. I see this exact question has already been asked at least on…

The httpclient library returns -1 as a error code for a few possible problems. HTTP is carried over TCP, so the library uses the built-in TCPClient to connect to the remote host. The TCP client could not connect to the remote host. Check your hostname or IP address or DNS server. Or perhaps the …

Hi and thanks for your input! This is my code: http://hastebin.com/dupupamezu.cpp I have zero problems with my ip (ping works perfect, wifi signal is strong etc) and I do actually receive a response body (at least my server is sending it and whenever I receive it I see it in my serial monitor). C…

Hi @ltpitt The first thing I would try to do is test without the InternetButton library. There could be some kind of interaction there so I would just have your code a GET to each of the URLs in order one every say 10 seconds so I could debug. In the code you presented, you are using “osmc” as a …

Is it possible you could get -1 if the Photon drops its wifi connection? Mine is out in the back yard which is pretty much fringe reception. I’m showing signal strength sometimes as low as -78 dB. Or better yet, is there a function I can call to tell the current status of the wifi, eg. connected …

I, too, seem to be among the folk having trouble with the HttpClient library. I’ve attached mine, and I keep getting Response status: -1. #define LOGGING doesn’t show anything, and I can curl “ http://www.cbc.ca/ ” from my computer successfully. Have I got #define LOGGING in the correct place? I appa…

I think LOGGING needs to be defined in HttpClient.cpp. That works for me. I’m locally compiling so am able to edit the library files.

Thanks, timx. I ran it in Particle Dev, and now I see a more precise error – apparently there is a missing body! Any ideas? Application > Start of Loop. HttpClient> Connecting to:cbc.ca:80 HttpClient> Start of Http Request. GET / HTTP/1.0 Connection: close HOST: cbc.ca Accept: */* HttpClient > End…

So I just took a quick look and www.cbc.ca (at least where I am) can be served up by an Akamai edge router, so the HOST field in the request is very critical. I see in your debug print that it says HOST: cbc.ca but I would change that to be the exact hostname you are reaching www.cbc.ca instead. W…

That sounds like what I need. I will have it print a warning if it ever goes false and see if that matches when I get the -1’s from http.get. Thanks!
