I run this url in my browser
http://www.bing.com/search?q=italy&cc=us&qdr:d
and I get 260M (million) results.
I run it on my webserver with curl and I get only 28 (literal) results?
What causes this with bing?
I ended up using yahoo since returns the same results anyway and has no problem on the server.

I've got a working local website that takes in HTML form data.
The fields are:
Temperature
Humidity
The server successfully receives the data and spits out a graph updated with the new entries.
Using a browser tool, I was able to capture the actual POST request as follows:
http://127.0.0.1:5000/add_data
Temperature=25.4&Humidity=52.2
Content-Length:30
Now, I want to migrate from using the human interface browser with manual entries to an ESP01 device using AT commands.
According to the ESP AT-commands documentation, a POST request is performed using the following command:
AT+HTTPCPOST=
Find the link below for the full description of the command.
I cannot seem to get this POST request working. The ESP01 device immediately returns an "ERROR" message without any delay, as though it did not even try to send the request, that the syntax might be wrong.
Among many variations, the following is my best attempt:
AT+HTTPCPOST="http://MYIPADDR:5000/add_data",30,2,"Temperature: 25.4","Humidity: 52.2"
With MYIPADDR above replaced with my IP address.
How do I translate a post request into ESP01 AT command format, and are there any prerequisites needed to be in place to perform such a request?
I did connect the ESP01 device to the WiFi network.
Here's the link to the POST AT command description:
https://docs.espressif.com/projects/esp-at/en/release-v2.2.0.0_esp8266/AT_Command_Set/HTTP_AT_Commands.html#cmd-httpcpost
The documentation says:
AT+HTTPCPOST=url,length[,<http_req_header_cnt>][,<http_req_header>..<http_req_header>]
Response:
OK
The symbol > indicates that AT is ready for receiving serial data, and you can enter the data now. When the requirement of message length
determined by the parameter is met, the transmission starts.
...
Parameters
: HTTP URL. : HTTP data length to POST. The maximum
length is equal to the system allocable heap size.
<http_req_header_cnt>: the number of <http_req_header> parameters.
[<http_req_header>]: you can send more than one request header to the
server.
You're sending:
AT+HTTPCPOST="http://MYIPADDR:5000/add_data",30,2,"Temperature: 25.4","Humidity: 52.2"
The length is 30. The problem is that everything after the length is HTTP header fields; you need to send the variables in the body. So the command is:
AT+HTTPCPOST="http://MYIPADDR:5000/add_data",30
followed on the next line by after the ESP-01 send the > character:
Temperature=25.4&Humidity=52.2
Because you passed 30 as the body length, the ESP-01 will read exactly 30 characters after the end of the AT command and send that data as the post body. If the size of that data changes (for instance, maybe the temperature is 2.2, so one digit less), you'll need to send the new length rather than 30.
I'm using Firebase API to generate short link:
https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=XYZ
It work most of time and generated expected result like https:// abc123.app.goo.gl/WXYZ but randomly it sometime generated https:// goo.gl/xyz sort of link. And finally when this executed by client it does not contain expected parsed result.
I have no idea why this is happening. Any one suggestion what's wrong going here.
I'm trying to send a SMS using AT commands and after typing the cellphone number it show the CMS: ERROR 302.
What I'm doing:
AT
OK
AT+CMGF=1
OK
AT+CMGS="<3 digit local area code><7 digit cellphone number>"<Enter>
+CMS: ERROR 302
I've found this post: AT+CMGS returns ERROR but couldn't find a solution. Am I typing something wrong? I've changed SMS-encoding to GMS as the post describes.
Try this:
AT
AT+CMGF=1
AT+CSCA="sms tel. service",145
AT+CMGS="tel. number"
text message here
^Z
Some modems need set CSCA (SMS Service Center Address) always.
And look here for a examples and descriptions.
I found out that sending exactly the same AT commands by hand worked, but sending them from a controller did not (with waiting for the correct answers). Getting the 302 error. But then doing all commands a lot slower with waits of 2 secs in between it suddenly started to work. Apparantly the SIM900 needs more time after it answers, or something.
I get the mails from the code below after getting the security token. My problem is that in my test account, there are 22 mails (in the inbox) and the returned JSON contains only the first 10 emails.
var json = JObject.Parse(await response.Content.ReadAsStringAsync());
My get is the following code:
https://graph.microsoft.com/v1.0/me/messages
I checked the resulting JSON and I can see the first 10 emails correctly.
What do I need to do to get all emails? (i.e. get the next 10, next 10... until I have all emails?)
10 is the default page size, so this is expected. You can expand the page size using $top up to 50. After that you need to request subsequent pages. There should be an #odata.nextLink included in the response which contains a URL to get the next page.
I have moved my graph requests to a batch, and noticed that when more than one request parameter is passed, the request fails with error 400.
For example, this works when not batched:
facebook->api('/me/friends?limit=5000&fields=id')
But when the same graph url is moved to a batch request, I get a 400 error.
When I remove one of the parameters (either fields or limit), it works:
/me/friends?fields=id
/me/friends?limit=10
Anyone knows if this is a bug or should be like this for some reason?
Finally found the answer to my problem. It appears that the & char must be escaped with %26 in order for this to work.
So my code sample should be:
facebook->api('/me/friends?limit=5000%26fields=id')
Wish this was documented...
