POST request is not sent
I have a short Android-Java client program which sends a basic information to bottle-python server with POST method. In the first version of code, server does not show anything. However, In the second version it works but I cannot understand what this additional line do because it has anything to do with posting content. I really appreciate if someone helps me figure this out.(There is nothing wrong with the server code since I can properly send request with python requests and my browsers).
This is the first version of client code:
String url = "http://192.168.1.23:8080/"; URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setDoOutput(true); OutputStream os = con.getOutputStream(); PrintStream myPusher = new PrintStream(os ); myPusher.print("param1=hey");
String url = "http://192.168.1.23:8080/"; URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setDoOutput(true); OutputStream os = con.getOutputStream(); PrintStream myPusher = new PrintStream(os ); myPusher.print("param1=hey"); InputStream in= con.getInputStream(); //Nothing changed but only this additional line
@app.route('/', method="POST") def hello(): print("it works") name = request.forms.get("param1") print(name) return name @app.route('/') def hello(): i=0 print("it works") run(app, host="192.168.1.23", port=8080)
With first client code server shows nothing.
With second code server shows:
it works hey 192.168.1.24 - - [31/Dec/2018 17:10:28] "POST / HTTP/1.1" 200 3
Which is as I expected.
With your first code snippet the output stream is still open. So the server does not know if it got the complete request. Probably just closing the stream would work as well.
However, I would make at least a call to
getResponseCode to see the outcome of the request.
Requests, You will need to send body data with requests whenever Typically you will use body data with PUT , POST , and PATCH requests. Postman does not set any header type for the binary body type. When I make a post request the angular 2 http is not sending this request. this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions()) the http post is not sent to the server but if I make the request like this
The PrintStream is a buffered type, this means you should add a flush operation after each
print(), or use
HttpClient.post body param is not sent correctly when using , Current behavior. When sending http post request (using HttpClient) with body data (for example a json object), it looks that Angular send the json A POST request is typically sent via an HTML form and results in a change on the server. In this case, the content type is selected by putting the adequate string in the enctype attribute of the <form> element or the formenctype attribute of the <input> or <button> elements:
Your java code seems incomplete for sending a post request. I think by using this code, you can make it work for yourself.
POST Request Json Body Not Sending · Issue #1555 · Kong , Insomnia Version: 6.5.4_ Operating System: Mac OS High Sierra_ Details For whatever reason the POST req.body would not send through to Short answer: in POST requests, values are sent in the "body" of the request. With web-forms they are most likely sent with a media type of application/x-www-form-urlencoded or multipart/form-data.
Why is my browser sending an OPTIONS HTTP request instead of , The problem was that no matter what, the front-end developer couldn't make a call with correct content-type . Even though that Axios uses JSON POST is used to send data to a server to create/update a resource. The data sent to the server with POST is stored in the request body of the HTTP request: POST /test/demo_form.php HTTP/1.1
What is the POST Method? | POST Method Definition, This means that data sent through the POST method will not be visible in the URL, as parameters are not sent along with the URI. The format of an HTTP POST The URL './api/add' actually got redirected to './api/add/index.php'. therefore this bizarre side-affect which the new request after the redirect sent using GET instead of POST Solution use the full url './api/add/index.php'
AJAX - Send a Request To a Server, A cached file is not an option (update a file or database on the server). Sending a large amount of data to the server (POST has no size limitations). Sending user For forms that use HTTP POST, it may not be safe to retry so the browser asks the user for confirmation first. A "GET" request is often cacheable, whereas a "POST" request can hardly be. For query systems this may have a considerable efficiency impact, especially if the query strings are simple, since caches might serve the most frequent queries.
