Apache Httpclient Logging

1. Apache Httpclient Https
2. Apache Httpclient Log Request

I am using commons-httpclient 3.1 in an integration test suite. The default logging for HttpClient is extremely noisy and I can’t seem to turn it off. I’ve tried following the instructions here but none of them make any difference.

Following are the steps to upload a multipart entity using the HttpClient library. Step 1 - Create an HttpClient object. The createDefault method of the HttpClients class returns an object of the class CloseableHttpClient, which is the base implementation of the HttpClient interface. Using this method, create an HttpClient object −.

RestTemplate request/response logging is not a straightforward matter, as Spring Boot doesn't include it out-of-the-box. Fortunately, we've seen that we can use the Apache HttpClient logger to get a verbose trace of exchanged data. Or, we can implement a custom interceptor to get more human-readable logs. Hi Michael, I am not sure if I understand your question right. I have not used resteasy so far, but if I look in the modules folders and the module.xml for resteasy I can see the httpclient-4.1.1.jar and a dependency to commons-logging implemented by jcl-over-slf4j.

Mostly I just need to make the org.apache.http.wire logger shut up. Part of the problem is that I don’t know what type of logger HttpClient is trying to use and most of the problem is I’ve never used this library before. I tried creating a log4j.properties file and dropping it in my test/resources folder, modifying the master logging.properties file in jre/lib, and sending in the various logging options to Maven as specified on the logging page, and none of them make any difference.

Any help is appreciated…this is driving me nuts.

UPDATE: A correction: it appears the output in question is actually originating through jwebunit’s usage of HttpClient, not my own. Either way, it’s not desirable.

UPDATE: Thanks for the attempts so far. I’ve tried everything suggested below but still no luck. I have a file commons-logging.properties in my src/test/resources folder with the following contents

and a file log4j.properties in the same folder with the following contents

However, when I run my tests I still get a bunch of output like this:

This output for everything that comes across the wire is making this library unusable for me…that is until I can figure out how to turn it off. Is there anything special I need to do to get this log configuration read in?

Update log4j.properties to include:

Note that if Log4j library is not installed, HttpClient (and therefore JWebUnit) will use logback. In this situation, create or edit logback.xml to include:

Setting the log level to WARN with Log4j using the package name org.apache.commons.httpclient in log4j.propertieswill not work as expected:

This is because the source for HttpClient (v3.1) uses the following log names: Pages for mac open with word.

Note: Some of this answer might repeat things you already know (or think you know), but there is a bit of mis-information floating around on this question, so I’m going to start at the beginning and spell it all out

• Commons HttpClient uses Commons-Logging for all its logging needs.
• Commons-Logging is not a full logging framework, but rather, is a wrapper around several existing logging frameworks
• That means that when you want to control the logging output, you (mostly) end up configuring a library other than Commons-Logging, but because Commons-Logging wraps around several other libraries, it’s hard for us to guess which one to configure without knowing your exactly setup.
• Commons-Logging can log to log4j, but it can also log to java.util.logging (JDK1.4 logging)
• Commons-Logging tries to be smart and guess which logging framework you are already using, and send its logs to that.
• If you don’t already have a logging framework, and are running on a JRE that’s 1.4 or above (which you really should be) then it will probably be sending its log messages to the JDK logging (java.util.logging)
• Relying on Commons-Logging’s autodiscovery mechanism is prone to error. Simply adding log4j.jar onto the classpath would cause it to switch which logging mechanism it uses, which probably isn’t what you want
• It is preferable for you to explicitly tell Commons-Logging which logging library to use
• You can do this by creating a commons-logging.properties file as per these instructions
• The steps you want to follow to configure the commons-httpclient logging are
  1. Decide which underlying logging framework you want to use. There are a number of choices, but probably log4j or java.util.logging are the best options for you.
  2. Set-up the commons-logging properties file to point to the correct Log implementation. e.g. to use log4j, put this into the properties file: org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger, or to use JDK logging set org.apache.commons.logging.Log=org.apache.commons.logging.impl.Jdk14Logger. These can also be set as system properties (e.g. using -D on the command line).
  3. Configure the underlying logging implementation (e.g. log4j) to ignore the messages you don’t want, and output the messages you do want.

That’s a lot of steps, but that’s what it takes. The developers at Apache-commons tend to assume you’ll already have a logging framework configured, and they can work out which one it is by auto-discovery.
If that’s not true for you, then it tends to be a bit more work to get things running.

I put this into my log4j config file

This limits the output to Warning level or above

For log4j, add the following to log4j.properties (in the application’s source directory):

For logback, the following logback.xml will kill the noise:

We use XML, rather than a properties file, to configure our logging output. The following code worked to silence this chatter.

It took far too long to find this out, but JWebUnit comes bundled with the Logback logging component, so it won’t even use log4j.properties or commons-logging.properties.

Instead, create a file called logback.xml and place it in your source code folder (in my case, src):

Logback looks to still be under development and the API seems to still be changing, so this code sample may fail in the future. See also this StackOverflow question.

In your log4.properties – do you have this set like I do below and no other org.apache.http loggers set in the file?

Also if you don’t have any log level specified for org.apache.http in your log4j properties file then it will inherit the log4j.rootLogger level. So if you have log4j.rootLogger set to let’s say ERROR and take out org.apache.http settings in your log4j.properties that should make it only log ERROR messages only by inheritance.

UPDATE:

Create a commons-logging.properties file and add the following line to it. Also make sure this file is in your CLASSPATH.

org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Log4jFactory

Added a completed log4j file and the code to invoke it for the OP. This log4j.properties should be in your CLASSPATH. I am assuming stdout for the moment.

Here is some code that you need to add to your class to invoke the logger.

I had the same problem with JWebUnit. Please notice that if you use binary distribution then Logback is a default logger. To use log4j with JWebUnit I performed following steps:

• removed Logback jars
• add lod4j bridge library for sfl4j – slf4j-log4j12-1.6.4.jar
• add log4j.properties

Probably you don’t have to remove Logback jars but you will need some additional step to force slf4j to use log4j

Simple way Log4j and HttpCLient (v3.1 in this case, should work for higher, could require minor changes)

Make sure all the dependencies are correct, and MD5 your downloads!!!! Pmb for mac.

The following 2 lines solved my problem completely:

I’ve been plagued by the same issue for quite some time now and finally decided to look into this. It turned out the issue is that my project had a dependency on http-builder-0.5.2.jar which bundled a log4j.xml file within itself. And sure enough, the log level for org.apache.http.wire was DEBUG! The way I found it was just to go through all the jar files in my dependencies and do “jar tvf” and grepping for log4j.

While this discovery led to the eventual solution of upping the version of my http-builder dependency to 0.6, it still baffles me what must have gone through the developer’s mind when bundling the log4j.xml file into the jar file. Anyway, that’s probably not relevant to this thread for now. But I figured it’s useful to mention this solution I found given that when I was searching for a solution before now, mine never came up. Hopefully someone will find this useful.

I was led to this post when searching for solution for similar problem. Tim’s answer was very helpful. like Matt Baker, I just want to shut off httpClient log without too much configuration. As we were not sure which logging implementation underneath common-logging was used, My solution was to force it using log4j by throwing log4j jar file in the class path. Default setting of log4j configuration shuts off common-httpclient debug output. Of course, to make it more robust, you may create common-logging.properties and log4j.properties files to further define your logging configurations.

I had this same problem when running jwebunit integration tests. I fixed it by excluding logback and adding in slf4j-log4j12, like so:

This took me ages to figure out once, you need this:

I guess HttpClient uses “httpclient.wire” as its logger name, not “org.apache.commons.httpclient”.

Sneaky buggers.

Apache Httpclient Https

Add the below lines in the log4j property file and it will shut the http logs :- log4j.logger.org.apache.http=OFF

The best solution I found was to use the maven enforcer plugin in order to prevent commons-logging from being used altogether. Then I added the slf4j dependency for logging instead. So add the following to your pom.xml

and also add the maven-enforcer plugin

I experienced such problem after setting HttpComponentsClientHttpRequestFactory for my rest template.

Setting OkHttpClientHttpRequestFactory should solve problem with trash logging.

First, we'll show how to send a custom cookie with an HttpClient request. Then, we'll see how to get it from the response.

Narrator for mac. Please note that the code examples presented here are based on HttpClient 4.3.x and above, so they won't work on older versions of the API.

First, we create a basic cookie store and a basic cookie with the name custom_cookie and value test_value. Then, we create an HttpClientContext instance that will hold the cookie store. Finally, we pass the created context as an argument to the execute() method.

3. Accessing Cookies

Now that we've sent a custom cookie in a request, let's see how to read it from the response:

To get our custom cookie from the response, we must first get the cookie store from the context. Then, we use the getCookies method to get the cookies list. We can then make use of Java streams to iterate over it and search for our cookie. Additionally, we log all cookie names from the store:
