All,
I am accessing a web-page through command prompt using simple_html_dom in php as
$page = file_get_html($url, false, $context);
where $url is the web-URL.
If you URL is like http://abc.com/xyz.html?s="sometext"
Then i am getting proper response.
But I am getting HTTP/1.1 400 Bad Request if the URL has white space in the get parameter like http://abc.com/xyz.html?s="some text".
Can anyone please help me how to resolve this issue.
Thanks in advance.
You need to encode the parameter:
$text = urlencode('some text');
$url = "http://abc.com/xyz.html?s=$text";
$page = file_get_html($url, false, $context);
If you're generating that url yourself, you'll have to url_encode the query values:
$url = 'http://example.com/xyz.html?s=' . urlencode('some text');
which'll give you
http://example.com/xyz.html?s=some+text
^---spaces must be + in urls.

I followed these steps:
Registered a bot with BotFather.
Send a post request for the webhook (https://api.telegram.org/bot[BOTID]/setWebhook) with the URL being https://example.com/myscript.php
Double check with getWebhookInfo and it showed it is correctly registered.
When I send a message to the bot, the script is being called but with an empty POST payload. In the documentation they say they would send an HTTPS POST request to the specified url, containing a JSON-serialized Update.
Does anyone else has this issue and perhaps know a way to resolve this?
My php script to log:
$file = dirname(__FILE__) . '/telegram-log.txt';
$entry = (object)array();
$entry->date = date("r");
$entry->GET = $_GET;
$entry->POST = $_POST;
$entry->REQUEST = $_REQUEST;
$entry->HTTP_USER_AGENT = $_SERVER['HTTP_USER_AGENT'];
$entry->REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];
file_put_contents($file, json_encode($entry) . "\n", FILE_APPEND | LOCK_EX);
Response:
{"date":"Thu, 17 Jun 2021 13:42:49 +0200","GET":[],"POST":[],"REQUEST":[],"HTTP_USER_AGENT":null,"REMOTE_ADDR":"91.108.6.133"}
Use $content = file_get_contents("php://input") to receive updates.
Telegram's response is of content-type application/json.
$_POST will only work when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.
I am trying to build a gnome shell extension (using gjs) that I need to communicate with an external REST API. In order to do so, I need to accompany my requests with the header: Authorization: Bearer <token> and with a Content-Type: application/json.
I have looked all over for questions like this and I did find some similar ones but none of them works. The documentation is not helpful at all, and, if anything, it has only confused me more.
With curl I could send that request as follows:
curl -X GET -H "Authorization: Bearer <token>" -H "Content-Type: application/json" <url>
So far, I have only created extensions that send simple GET requests with no headers. Then I would do the following:
const Soup = imports.gi.Soup;
let soupSyncSession = new Soup.SessionSync();
let message = Soup.Message.new('GET', url);
let responseCode = soupSyncSession.send_message(message);
let res;
if(responseCode == 200) {
res = JSON.parse(message['response-body'].data);
}
Any idea on how I can add the headers? Any help would be appreciated!
EDIT:
By using #ptomato's answer I ended up using the following code:
function send_request(url, type='GET') {
let message = Soup.Message.new(type, url);
message.request_headers.append(
'Authorization',
`Bearer ${token}`
)
message.request_headers.set_content_type("application/json", null);
let responseCode = soupSyncSession.send_message(message);
let out;
if(responseCode == 200) {
try {
out = JSON.parse(message['response-body'].data);
} catch(error) {
log(error);
}
}
return out;
}
Initial Comment:
So, I managed to find a workaround but it is not efficient and so I will not mark it as the accepted answer. If anyone knows how to answer my question using Soup, please answer!
My workaround involves using the imports.misc.util file which includes the function spawnCommandLine for executing shell commands. So, I used curl in order to download the json to a file (the path variable below):
Util.spawnCommandLine(`/usr/bin/curl -X ${type} -H "Authorization: Bearer ${token}" -H "Content-Type: application/json" ${url} -o ${path}`);
and then I read the contents by using the following:
let text = GLib.file_get_contents(path)[1];
let json_result = JSON.parse(text);
This is not efficient at all and there should be an easier way around. But, until that is found, I hope this will be able to help someone else.
message.request_headers is a Soup.MessageHeaders object to which you can append() the authorization and content type headers.
Additionally there is a convenient set_content_type() method for the content type header specifically.
I use Express-graphql middleware.
I send the following request in the body line:
POST /graphql HTTP/1.1
Host: local:8083
Content-Type: application/graphql
Cache-Control: no-cache
Postman-Token: d71a7ea9-5502-d5fe-2e36-0ae49c635a29
{
testing {
pass(id: 1) {
idn
}
}
}
and have error
{
"errors": [
{
"message": "Must provide query string."
}
]
}
in graphql i can send update in URL.
URL string is too short. i must send update model like
mutation {
update(id: 2, x1: "zazaza", x2: "zazaza", x3: "zazaza" ...(more more fields)...) {
idn
}
}
I think its must be in request body. How can I send 'update' query or that I'm doing wrong?
Post request needs to manage headers info.
Using Http client - Content-Type: application/json
Using Postman client - Content-Type: application/graphql
but request body looks like string
{"query":"mutation{update(id:1,x1:\"zazaz\",x2:\"zazaz\"......){id x1 x2}}"}
If you are using graphql and want to test it using postman or any other Rest client do this.
In postman, select POST method and enter your URL and set Content-Type as application/graphql then pass your query in the body.
Example:
http://localhost:8080/graphql
Mehtod: POST
Content-Type: application/graphql
Body:
query{
FindAllGames{
_id
title
company
price
year
url
}
}
Thats it you will get the response.
Using Postman Version 7.2.2 I had a similar issue. This version of Postman supports Graphql out of the box. Changing the Content-type to application/json fixed it for me.
for me worked like as following:
In the body
In the Headers
Don't forget mark GraphQl [x] on Body settings
And how was quoted before changes the verb to POST.
This generally occurs when your 'express-graphql' doest receive any params. You need to added a json/applicaton parser in your application.
npm install body-parser
eg -
const bodyParser = require('body-parser');
app.use(bodyParser.json()); // application/json
go to the relevant web page and open "inspect" (by write click ->
inspect || Ctrl+Shift+I in chrome)
go to the network tab and copy the cURL command
open the postman ,then import -> raw text
paste the copied command
then,continue ->
Switch content type to JSON.
Like this
Check if you are using correct protocol in your Postman requests.
I used HTTP instead of HTTPS and this caused the same error.
Changes of content-type, raw or json instead of graphql type didn't help.
Does anyone know how to extract html response from Guzzle HTTP client? If you look at the example below, we can get xml and json response easily but I don't know how to get plain text or HTML response string.
Documentation didn't have an option for plain text or HTML unlike json() and xml().
$client = new Client($base_url);
$request = $client->createRequest($method, $uri, null, $this->requestPayload);
$response = $client->send($request);
$xml = $response->xml(); // For XML response
$json = $response->json(); // For JSON response
$html = $response->????????(); // For plain text or HTML response
Solution:
This returns the whole response body as we see in browser.
$response->getBody(true)
I have an issue when trying to generate Access Token by POST data to https://login.bigcommerce.com/oauth2/token. There is an exception error ('The remote server returned an error: (400) Bad Request.'). I don't know why but I already read the document at https://developer.bigcommerce.com/apps/callback#token
If I open that URL on any web browsers. It said that "The page you were looking for doesn't exist."
Could you please help me this?
Thank you,
Trung
If you are getting a 400 response to your POST request to https://login.bigcommerce.com/oauth2/token then that is indicating a problem with your data. The most likely causes are:
You are not including the following header in your POST request:
Content-Type: application/x-www-form-urlencoded
You are not URL encoding your POST data such as the following example:
client_id=236754&client_secret=m1ng83993rsq3yxg&code=qr6h3thvbvag2ffq&scope=store_v2_orders&grant_type=authorization_code&redirect_uri=https%3A%2F%2Fapp.example.com%2Foauth%26context%3Dstores%2Fg5cd38&context=stores%2Fabc123
Also note that the error response message body that you receive should have some more details about the source of the problem.
If you have confirmed the above points then maybe try giving a sample of your POST data or some information about what you are doing to URL encode your data. Make sure not to include your actual client ID, client secret, or redirect URI.
Try ussing cURL
$data = array( "client_id" => "sdfgdfgdfkxddfgdfgdfdfgdfgddfgdfg2",
"client_secret" => "sdfgsdfgsdfgsdfgsdfgdf",
"redirect_uri" => "https://youapp.com/oauth",
"grant_type" => "authorization_code",
"code" => $_GET["code"], "scope" => $_REQUEST["scope"], "context" => $_GET["context"], );
$postfields = http_build_query($data);
$ch = curl_init();
$url = "https://login.bigcommerce.com/oauth2/token";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($ch);
curl_close ($ch);
$obj = json_decode($output);
var_dump($obj);
Firstly you need to get temporary authorization code, but sending GET request to https://login.bigcommerce.com/oauth2/authorize with parameters clientId, Scope, Context ("stores/{your_store_hash}") and redirect_url.
Only after this, you can change your temporary token to permanent token (see previous post).
This permanent token expires in 30-60 days, but I don't know how to renew it automatically without user action. If you know that, please write how.
