I'm trying to make a get request from a Arduino to Google App Engine:
client.println("GET /getData HTTP/1.0\r\n");
client.println("HOST: xxxxxxxxxx.appspot.com\r\n");
client.println("\r\n");
And I get the following error message:

I cant seem to get the formatting of the request right. Does anyone have a idea how to get it working? When I test it against WAMP server everything works fine. Thanks
This code should help you:
char server[]="your_server_name";
EthernetClient client;
IPAddress ip(192, 168, 1, 40); // Arduino IP Add
IPAddress myDns(8,8,8,8); // DNS
IPAddress myGateway(192,168,1,1); // your gateway
void setup() {
Serial.begin(9600);
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// try to congifure using IP address instead of DHCP:
Ethernet.begin(mac,ip,myDns,myGateway);
}
}
in the loop():
... loop funcion
if (client.connect(server,80)) // Server port
{
client.println("GET /getData HTTP/1.0\r\n");
client.println("HOST: host_name\r\n");
client.println("\r\n");

We run a service that synchronizes with Gmail using the REST API. Since last Wednesday, some of our (unchanged) Gmail tests have begun sporadically failing. The cause appears to be on the Gmail REST API side.
One failing test involves creating a label, creating a message, tagging a message with the label, and then renaming the label. When the tests fail, the POST request to change the label name returns a 404 error. A GET on that label or on the label list, either before or after the first 404, will successfully return the label in question. Retrying the POST keeps resulting in a 404 for at least 30 seconds, even with a 5-second gap between retries. Adding a 15-second delay before trying the POST doesn’t help.
Is this a known issue? If so, are there any known workarounds? What can we provide to help diagnose and fix this? We’re using the Google-HTTP-Java-Client/1.22.0 client library.

Looking at a few runs, the Server response header value differs between successes and failures (though that may be by design).
This is a very peculiar error. Patching of labels seem to be broken. I also get Error 404 (Not Found)!!1. What on earth?!
In the mean time your could just get the label data, and then update the fields that can be changed, but just changing the name to your liking:

The API Explorer does not work for some odd reason. However, if you change from POST to PATCH in your request, it will work:

In the same way that you get an instance's metadata via instance/attributes/xyz, so you can get the project's metadata via project/attributes/xyz.
curl http://metadata/computeMetadata/v1/project/attributes/groupip -H "Metadata-Flavor: Google"
To make sure you actually added the project-level metadata correctly, list all project attributes:
And more generally, keep shortening the URL to list ancestors:
I have issues when I try to call a GAPPS script that is published as a webapp. I am trying to call this service from AppEngine. I am doing a POST method to this script with a JSON Payload. Urlfetch options are set to follow redirects and a timeout of 30 secs. The script is publicly available and open to anonymous users.
On my local GAE development machine, the URLFetch response from the script is 200, and all is fine.
When I move to production, the script gets executed but returns errors and an HTML page.
I have follow redirects on on URLFetch and I have set the deadline to 30secs.

The funny - no so much - thing is that the script WORKS NEVERTHELESS most of the time but not always or not for all users.
You can see that thet response header says Allow=HEAD, GET but I implemented doPOst in my script.
Nevertheless, I have tried solving this problem by rewriting the whole things to work with GET and a parameter but I am running into similar issues !

GAS is very picky when running as webapp. Sometimes it helps to put the script into a public folder on Google Drive.
How to parse mime body part using Java Mail MimeMessage, I am fetching BODY part alone from my IMAP server.
Command I used to fetch BODY part alone.
A001 UID FETCH 1 (UID FLAGS BODY.PEEK[1])
This will fetch raw MIME message without headers and attachments ( but contains inline images ).
When I parse the fetched content using Java Mime Message, I am getting wrong result.
For Example : If the raw MIME contains inline images part.getInputStream() return content with inline image data
Raw MIME:

Can any one suggest how to parse body using Java MimeMessage.
Thanks.
You are getting just the .TEXT portion (i.e. the content of the part), but you need to combine the .MIME and the .TEXT before you'll be able to parse it.
You can see how I do this in my own IMAP library (written in C#, though) in the GetBodyPart method of ImapFolder.cs:
https://github.com/jstedfast/MailKit/blob/master/MailKit/Net/Imap/ImapFolder.cs#L3729
Effectively I request <part-spec>.MIME and <part-spec>.TEXT and then chain them together in a custom ChainedStream class that takes a list of streams and reads from them as if they were a single, sequential, stream.
Are you implementing the IMAP protocol support yourself instead of using the IMAP protocol support built in to JavaMail? If so, you need to spend a lot more time reading the IMAP protocol spec!
To get the entire message content, leave out the section id - BODY.PEEK[].
I want to create a html email and I've read a lot about how to do it. There is one piece of information I can't find. How should I declare the mime type? I tried with:
meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
but it doesn't work.
Later edit:
I am trying to set the content-type of the mail to text/html but I don't know how. All this when writing from a regular email client. I have to declare it in the mail body? Or in the mail header (if so, how do I o it?)?
Are you trying to set the content-type declaration within the message header sent to the mail server? If so, you should set it this way, in a line itself:
Content-Type: text/html; charset=UTF-8
The end tag for meta tag is used only in xhtml/xml. If you are using html, you should use it inside <head> tags like:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
Basically email clients ignore any META tags with Content type in them (at least as of 2013-10-17).
You need to set a the content type declaration in a special header in the email server.
More information about this issue can be found at http://www.emailonacid.com/blog/details/C13/the_importance_of_content-type_character_encoding_in_html_emails
If this makes no sense to you, then I'm afraid you're out of luck. The only reliable solution I've found is to convert any special characters to their HTML entity equivalent. The link above has a link to a tool that does this for you.
Hope that helps!
This applies to php:
// To send HTML mail, the Content-type header must be set
$headers[] = 'MIME-Version: 1.0';
$headers[] = 'Content-type: text/html; charset=iso-8859-1';
// Additional headers
$headers[] = 'To: Mary <mary#example.com>, Kelly <kelly#example.com>';
$headers[] = 'From: Birthday Reminder <birthday#example.com>';
$headers[] = 'Cc: birthdayarchive#example.com';
$headers[] = 'Bcc: birthdaycheck#example.com';
// Mail it
mail($to, $subject, $message, implode("\r\n", $headers));
