Re: $_POST is empty when request made using RequestBuilder
Thanks everyone very nice tips and links.
Salk31 Cokol, you were right, I didn't need the ?, PHP page
wouldn't get the first parameter because of the ?
VM, nice article and very smart hack... but it got me wondering
whether I will be able to maintain status on the server (using
sessions), especially after I read the other hack on how to use the
iframe name to store information.
I am lucky that I am controlling both the PHP pages and GWT
application, and both will be running from the same domain and server,
so I tried deploying both on the same server and they communicate
perfectly with no hassle using RequestBuilder. These issues are raised
when I try to run the GWT application through Eclipse.
I could be wrong, but it seems like no matter what technique you use
to send a cross server POST request, will give you a lot of pain
especially if you are interested in maintaining status...
Thanks a bunch.

hi!
so if you really need to go for HTTP POST rather than get, then do so,
remove the '?' from post body, these would be required for CGI doing
GET but not in this case.
you dont need to go for JSNI!! SOP cannot be workarounded on the
client solely. You have to write simple gateway service which you call
from the client (via RequestBuilder or XMLHttpRequest) and the data is
posted via socket from the backend to the destination server.

The problem was because I wasn't encoding the URL, Now when I think
about it, it is kind of strange because the logs show that a request
was sent but the only problem was with the $_POST, You would expect
not being able to send the request if you don't encode the url and not
send a request with no parameters.
What was interesting too, the fact that getStatusCode() returned 0. I
checked the group and it seems that it has something to do with SOP
(correct me please if I am wrong). Would having the GWT application in
the same folder as the PHP project solve this issue?

I don't see anything in particular that is wrong with your code, but
the following works for me if you want to give it a try:

url = URL.encode(url);
RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST,

try {
builder.setHeader(Content-Type, application/x-www-form-

response) {

});
} catch (RequestException e) {
fireErrorEvent(Failed to send therequest: +

You can look at 'output' which should display any echos you have in
your PHP. Hopefully this will help you debug out what is happening.
If this doesn't work check that you are not violating the SOP (same
origin policy). There are other threads on this forum with more info

Re: $_POST is empty when request made using RequestBuilder
btw:
you can of course abuse HTML resource reference tags allowing SOP
( like SCRIPT, IMG, IFRAME ) but they all do only support HTTP GET. If
your service you gonna talk with requires HTTP POST, there is no other
way
you can also patch your DNS but this is for sure not the way you look
for...

Re: $_POST is empty when request made using RequestBuilder
Thanks Rob,
The problem was because I wasn't encoding the URL. Wired, I would
expect the whole request to fail if I don't encode the URL.
Another thing, I received 0 (zero) as status code, i checked the
forums and it seems that it is related to SOP as you suspected. Would
having the PHP files in the same www folder as the GWT application
solve this issue?
Are there any workarounds to SOP?

I am really new to GWT, I tried searching the net for hours to get an
answer to my problem with no luck. Here is what I am doing:
I am creating a simple EntryPoint which shows some text fields, when
the user clicks on a button I want to send a POST request to a php
page. The PHP page says that my request parameters are not set.
Right before I send the request I display the request data and they
look right. As the code shows, I am setting the content type, I am
appending the parameters properly, I don't know what is wrong.
I didn't want to use FormPanel because it seemed like I wouldn't be
able to send a request asynchronously (correct me if I am wrong, my
conclusion was based on Javadoc's examples also some examples on the
net)
Here is the code:
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, url);
builder.setHeader(Content-type, application/x-www-form-
urlencoded);
StringBuffer requestData = new StringBuffer();
// parameters is a HashMap
if (parameters != null ){
requestData.append(?);
SetString keys = parameters.keySet();
for (String key : keys ){
requestData.append(URL.encode(key));
requestData.append(=);
requestData.append(URL.encode(parameters.get(key)));
requestData.append();
}
}
try {
Window.alert(requestData.toString());
builder.sendRequest(requestData.toString(), handler);} catch (
Exception e){
Window.alert(e.getMessage());
}
Please help.

Re: $_POST is empty when request made using RequestBuilder
Thanks Rob,
The problem was because I wasn't encoding the URL, Now when I think
about it, it is kind of strange because the logs show that a request
was sent but the only problem was with the $_POST, You would expect
not being able to send the request if you don't encode the url and not
send a request with no parameters.
What was interesting too, the fact that getStatusCode() returned 0. I
checked the group and it seems that it has something to do with SOP
(correct me please if I am wrong). Would having the GWT application in
the same folder as the PHP project solve this issue?
Please, are there any other work arounds to the SOP issue?
Thanks again

I don't see anything in particular that is wrong with your code, but
the following works for me if you want to give it a try:
public void postPHPRequest(String url, String postData){
url = URL.encode(url);
RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST,
url);
try {
builder.setHeader(Content-Type, application/x-www-form-
urlencoded);
@SuppressWarnings(unused)
Requestreq = builder.sendRequest(postData, new
RequestCallback() {
public void onError(Requestrequest, Throwable exception) {
fireErrorEvent(Failed to send therequest: +
exception.getMessage());
}
public void onResponseReceived(Requestrequest, Response
response) {
String output = response.getText();
}
});
} catch (RequestException e) {
fireErrorEvent(Failed to send therequest: +
e.getMessage());
}
}
You can look at 'output' which should display any echos you have in
your PHP. Hopefully this will help you debug out what is happening.
If this doesn't work check that you are not violating the SOP (same
origin policy). There are other threads on this forum with more info
on this.
Good luck,
Rob

Re: $_POST is empty when request made using RequestBuilder
Although I can't see anything obviously incorrect with your code, the
following code snippet successfully sends a POST request in my code:
public void postPHPRequest(String url, String postData){
url = URL.encode(url);
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST,
url);
try {
builder.setHeader(Content-Type, application/x-www-form-
urlencoded);
@SuppressWarnings(unused)
Request req = builder.sendRequest(postData, new
RequestCallback() {
public void onError(Request request, Throwable exception) {
fireErrorEvent(Failed to send the request: +
exception.getMessage());
}
public void onResponseReceived(Request request, Response
response) {
String output = response.getText();
}
});
} catch (RequestException e) {
fireErrorEvent(Failed to send the request: + e.getMessage());
}
}
You can look at the content of 'output', which should display any
echo's in your php code.
If you still have no luck, check that you are not violating the rules
of the SOP.
Good luck,
Rob
