I'm using HttpRequestBase and I want to log the request fully to a log file before using it.
The default toString returns only the request line and I want to print all the headers, parameters, request body etc...
Is there a way to do so?
The HttpRequestBase object (HttpGet, HttpPost, etc.) contains information about the headers, parameters, and the implementation class contains the body, but it's not actually serialized into a String. That happens when the HttpClient actually sends the request.
You can play with the http components logging configuration.
Or you can call the appropriate methods and do it yourself.
HttpRequestBase base = new HttpGet("www.google.com");
Header[] headers = base.getAllHeaders();
// iterate and print
For the body, you need to cast to your implementation class and get the HttpEntity, if it has one.
HttpEntity entity = ((HttpPost)base).getEntity(); // example
And print it (its InputStream content). Note: That might consume the entity.
Full example
HttpPost post = new HttpPost("www.google.com");
post.setHeader(new BasicHeader("User-Agent", "random client"));
HttpEntity entity = new StringEntity("yellaworld");
post.setEntity(entity);
Header[] headers = post.getAllHeaders();
String content = EntityUtils.toString(entity);
System.out.println(post.toString());
for (Header header : headers) {
System.out.println(header.getName() + ": " + header.getValue());
}
System.out.println();
System.out.println(content);
prints
POST www.google.com HTTP/1.1
User-Agent: random client
yellaworld
This works
private void printRequest() {
System.out.println("receive " + httpRequest.getMethod() +" notification for "+ httpRequest.getRequestURI());
System.out.println(" \n\n Headers");
Enumeration headerNames = httpRequest.getHeaderNames();
while(headerNames.hasMoreElements()) {
String headerName = (String)headerNames.nextElement();
System.out.println(headerName + " = " + httpRequest.getHeader(headerName));
}
System.out.println("\n\nParameters");
Enumeration params = httpRequest.getParameterNames();
while(params.hasMoreElements()){
String paramName = (String)params.nextElement();
System.out.println(paramName + " = " + httpRequest.getParameter(paramName));
}
System.out.println("\n\n Row data");
System.out.println(extractPostRequestBody(httpRequest));
}
static String extractPostRequestBody(HttpServletRequest request) {
if ("POST".equalsIgnoreCase(request.getMethod())) {
Scanner s = null;
try {
s = new Scanner(request.getInputStream(), "UTF-8").useDelimiter("\\A");
} catch (IOException e) {
e.printStackTrace();
}
return s.hasNext() ? s.next() : "";
}
return "";
}

I am looking to interact with a Documentum Repository using their REST API. I would like to use the http-client 4.3 jars to perform this interaction.
I was hoping someone might have a sample that would help point me in the correct direction on how to interact with DCTM.
I am having trouble finding a clear and simple example of how to do this.
Thanks
I know it is a bit late to answer this question. But i want to answer to help those who still need a code for making requests to the rest api. Here is a full example of sending a post request to the rest api for starting a workflow.
For other needs you can check the Document called Documentum xCP Rest Services provided by EMC : https://support.emc.com/docu52500_Documentum-xCP-REST-Services-2.1-Development-Guide.pdf?language=en_US&request=akamai and compare with this example, change it according to it's needs.
UPDATE:
Also if you are not using xcp here is the Documentation for rest api without it emc.com/collateral/TechnicalDocument/docu57895.pdf
You can also check my answer here How can I use REST to copy an object in Documentum 7.x for geting object data and content from the rest api ( without xcp )

I intend to send a simple http post request with a large string in the Payload.
So far I have the following.
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("address location");
String cred = "un:pw";
byte[] authEncBytes = Base64.encodeBase64(cred.getBytes());
String authStringEnc = new String(authEncBytes);
httppost.setHeader("Authorization","Basic " + authStringEnc);
However, I do not know how to attach a simple RAW string into the payload. The only examples I can find are name value pairs into the Entity but this is not what I want.
Any assistance?
It depends on the concrete HTTP-API you're using:
Commons HttpClient (old - end of life)
Since HttpClient 3.0 you can specify a RequestEntity for your PostMethod:
httpPost.setRequestEntity(new StringRequestEntity(stringData));
Implementations of RequestEntity for binary data are ByteArrayRequestEntity for byte[], FileRequestEntity which reads the data from a file (since 3.1) and InputStreamRequestEntity, which can read from any input stream.
Before 3.0 you can directly set a String or an InputStream, e.g. a ByteArrayInputStream, as request body:
httpPost.setRequestBody(stringData);
or
httpPost.setRequestBody(new ByteArrayInputStream(byteArray));
This methods are deprecated now.
HTTP components (new)
If you use the newer HTTP components API, the method, class and interface names changed a little bit, but the concept is the same:
httpPost.setEntity(new StringEntity(stringData));
Other Entity implementations: ByteArrayEntity, InputStreamEntity, FileEntity, ...
i was making a common mistake sequence of json object was wrong. for example i was sending it like first_name,email..etc..where as correct sequence was email,first_name
my code
boolean result = false;
HttpClient hc = new DefaultHttpClient();
String message;
HttpPost p = new HttpPost(url);
JSONObject object = new JSONObject();
try {
object.put("updates", updates);
object.put("mobile", mobile);
object.put("last_name", lastname);
object.put("first_name", firstname);
object.put("email", email);
} catch (Exception ex) {
}
try {
message = object.toString();
p.setEntity(new StringEntity(message, "UTF8"));
p.setHeader("Content-type", "application/json");
HttpResponse resp = hc.execute(p);
if (resp != null) {
if (resp.getStatusLine().getStatusCode() == 204)
result = true;
}
Log.d("Status line", "" + resp.getStatusLine().getStatusCode());
} catch (Exception e) {
e.printStackTrace();
}
return result;
Answer
I am struggling with creating a plain text file on a server via HTTP PUT. I am using apache commons httpClient. My credentials are working but there is no body content in my request. What must I do to create the file like this? It works as intended when I try via hurl.it (ie setting my credentials, and setting a body). What I would like is the string "hej" to show in the file body. After getting this to work I intend to use a JSONString. The following code generates an empty file on the server (204 response):
HttpClient httpClient = new DefaultHttpClient();
String encoding = http_username + ":" + http_password;
encoding = Base64.encodeBase64String(encoding.getBytes());
HttpPut httpput = new HttpPut(http_path);
HttpEntity content=null;
try{
content = new StringEntity("hej");
}
catch(UnsupportedEncodingException e){
logger.error("Failed to Encode result");
}
logger.info("executing request " + httpput.getRequestLine());
try {
httpput.setHeader("Authorization", "Basic " + encoding);
//httpput.setHeader("Content-Type", "application/json; charset=utf-8");
httpput.setEntity(content);
HttpResponse response = httpClient.execute(httpput);
Header[] allHeaders = response.getAllHeaders();
for (Header h : allHeaders) {
logger.info(h.getName() + ": " + h.getValue());
}
} catch (Exception e) {
logger.error(e.getMessage());
}
I have tried both setting a content type and not doing it, no difference. What basic thing am I doing wrong?
Turns out that Base64.encodeBase64String appends a newline character at the end of the string, which throws everything off!
String encoding = http_username + ":" + http_password;
encoding = Base64.encodeBase64String(encoding.getBytes());
encoding= encoding.replace("\r\n", ""); //This fixes everything
Wow, that just took me a couple of days to figure out!
