Error parsing HTTP request header



I am trying to send a POST request from browser to my server(local host). My request URL is :


POST


http://localhost:8080/myPath/myServlet?requestData= .......//Json String......;



requestData is a json String (I am using GSON for the purpose.) Everything is working fine until the data in the json string exceeds a particular limit. Say, I am sending array of objects in the json string. If the number of objects in the list exceed 67 then I get following error :


requestData


67


AM org.apache.coyote.http11.AbstractHttp11Processor process
INFO: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.



Why is this so? I am totally confused. Why does this happen and what needs to be done to fix this?
I want to understand the reason behind this, for I don't understand that after particular number of objects it suddenly stops working and I get this error in my console.



Thanks.





This seems to be a GET instead POST ...

It seems that you are passing the json string as a GET parameter, not POST.

It seems that you are using POST incorrectly. Although you are using POST you are sending JSON as a request parameter that is the GET style. When using POST you should send content as a request body. In this case no reasonable size limitation exist.





Can you show how it should be done ?

How can I send it from the browser?

You can write HTML page with form tag, define its method=POST and configure action to your URL, create text area field, then write your JSON there and press button submit.

form


method=POST


action


submit



I had a similar issue, I was sending a POST request (using RESTClient plugin for Firefox) with data in the request body and was receiving the same message.



In my case this happened because I was trying to use HTTPS protocol in a local tomcat instance where HTTPS was not configured.





thanks - that was my problem.

In my case problem was caused by security issues, i used csfr for authentication, and all my post forms should have input with _csrf


<input type="hidden" name="$_csrf.parameterName" value="$_csrf.token"/>



I apologize for not answering questions seriously before.



1.Maybe it caused by special characters.You can get details from this url。https://bz.apache.org/bugzilla/show_bug.cgi?id=60594



solve it by：


encodeURIComponent(JSON.stringify(data))



or change your tomcat version to 7.0.67 or lower.
According to developers's opinion, tomcat developers in the following versions set the option to allow |，，.
Get detail http://tomcat.apache.org/tomcat-8.0-doc/config/systemprops.html#Other


|，，



The new environment variable will be included in:
- trunk for 9.0.0.M18 onwards



8.5.x for 8.5.12 onwards



8.0.x for 8.0.42 onwards



7.0.x for 7.0.76 onwards2.



Another reason maybe that Request header is too large.You can solve this by modifying the server.xml.


server.xml


<Connector port="8080" maxHttpHeaderSize="8192" maxThreads="150"
minSpareThreads="25" maxSpareThreads="75" enableLookups="false"
redirectPort="8443" acceptCount="100" connectionTimeout="20000"
disableUploadTimeout="true" />



Hope it works for you！

IMHO the problem of parsing the headers can be caused by numerous reasons.


In my case it was due to the fact that the following XML was passed:


<soapenv:Header/>



The empty header element was generated by SoapUI.
After the removal of the <soapenv:Header/> from the XML of the WS then everything was fine.


<soapenv:Header/>



I fixed this by passing an additional header



connection: close, along with the request.



Could you please try and let me know if this works for you.

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use .

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
