Javascript not executing in Azure

Hi I forgot the image

Could you post the

console.log(req.body);

Select allOpen in new window

Hi Leonidas,

Thanks for responding. I'm 100% new with Javascript.

Can you let me know how to post the

console.log(req.body):

Select allOpen in new window

Add into your code the console.log as I show below and then check your console.

module.exports = function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    console.log(req.body);
    if (req.body && req.body.name && req.body.id && req.body.age && req.body.address){

    context.res = {
        //status: 200, /* Defaults to 200 */
        body: "Data is saved for user " + (req.body.name) +" !!"
    };

     context.bindings.outputDocument = JSON.stringify({
         id: req.body.id,
         name: req.body.name,
         age: req.body.age,
         address: req.body.address
     });
}
else {
    context.res = {
        status: 400,
        body: "Please pass all user details"
    };
}
context.done();

};

Select allOpen in new window

One of the if statement parameter is not pass the true statement.Also try to change the if statement with this:

 if ( req.body.name && req.body.id && req.body.age && req.body.address){
//code here...
}

Select allOpen in new window

Thanks,

Will try that now...

Hi still getting the same error

module.exports = function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    console.log(req.body);
    if (req.body && req.body.name && req.body.id && req.body.age && req.body.address){
    context.res = {
        //status: 200, /* Defaults to 200 */
        body: "Data is saved for user " + (req.body.name) +" !!"
    };

     context.bindings.outputDocument = JSON.stringify({
         id: req.body.id,
         name: req.body.name,
         age: req.body.age,
         address: req.body.address
     });
}
else {
    context.res = {
        status: 400,
        body: "Please pass all user details"
    };
}
context.done();

};

Select allOpen in new window

This also failed:

module.exports = function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    console.log(req.body);
    if ( req.body.name && req.body.id && req.body.age && req.body.address){
    context.res = {
        //status: 200, /* Defaults to 200 */
        body: "Data is saved for user " + (req.body.name) +" !!"
    };

     context.bindings.outputDocument = JSON.stringify({
         id: req.body.id,
         name: req.body.name,
         age: req.body.age,
         address: req.body.address
     });
}
else {
    context.res = {
        status: 400,
        body: "Please pass all user details"
    };
}
context.done();

};

Select allOpen in new window

Set pls the

context.log(req.body);

Select allOpen in new window

instead of console.log and post the output

Hi, after changing to context, this is the output

Any more thoughts?

It looks like the posted vars are not being converted - have you added a urldecoder to your app?

Hi Julian,

Thanks for responding.

I'm not sure about vars, however below is the out after I run the script with the test variables

"id":"1",
"name": "Carlton",
"age":"23",
"address":"London"

Ok but I would expect to see something like this from your dump of req.body

{ id: '1', age: '2', address: 'a', name: 'b' }

Select allOpen in new window

I think I see your problem though
You are doing a POST but defining your data as if it was JSON
In your Test window try this

id=1&name=Carlton&age=23&address=London

Select allOpen in new window

Hi Julian,

Thanks again. Going to try your suggestion now..

Hi julian,

I got the following error:

Wrong image.. see below

Ok then this is telling me that there is no server process that is processing the POST body - what we are seeing there is the raw post data - whereas what we want to be seeing is an object.

I am not familiar with the Azure platform - but somewhere in your app you need to be telling it that you are expecting URLEncoded data so that it knows how to decode it.
Are there any other files in your project.

Julian,

The attached image shows the options available in HTTP method

Thanks but that is not where the problem is. The test container just defines how you send your data to the backend service.

The problem here is on how the service is interpreting that data.

Is this your only app file or are there others listed behind View Files

Somewhere you must define how to interpret the incoming data.

Change the method to GET and retry. The key-values pairs are in the url and you must get them from this as I show at this documentation:

oh wow, Leonidas are you reading from the same book located here?

https://www.packtpub.com/mapt/book/virtualization_and_cloud/9781787122932/6/ch06lvl1sec32/building-the-project

I will try your suggestion

Cheers

So, I used GET and still no luck

I read from this Docs Azure

oh yeah, I successfully managed to implement the sample from that link

ahhhh  Julian, I think you might onto something there. I wil try and use the 'Add Parameter' option.

I will let you know how I get on.

Hi Julian,

I'm trying to figure out how to add the parameter into the request body after entering the ID + 1

Tried entering all the parameters, but still can't get the parameters added to the request body..

Get the url and add these parameter ass I posted above:

https//:some_url_here.net/api/HttpTrigger..etc?id=1&name=Carlton&age=23&address=London

Select allOpen in new window

Hi Leonidas,

I tried adding the parameter to the url as you suggested but it didn't work. However, adding the string as follows got a result but not the right result

https://projectfunction.azurewebsites.net/api/SaveDataAPI?code=aTqhABAA3TMKEhNRUQSawJnHFHjIUgiL/M8HW/0K4VkYwNk94n5G0g==&id=1&name=Carlton&age=23&address=London

Julian,

I added the parameters as you suggested. I'm still don't know what command to enter to get the parameters into the 'Request body' when I use the 'Add parameter' option.

Leonidas,

Do you know how to use the Add Parameter option?

Any of you guys still there to help?

Try with this:

https://projectfunction.azurewebsites.net/api/SaveDataAPI?code=aTqhABAA3TMKEhNRUQSawJnHFHjIUgiL/M8HW/0K4VkYwNk94n5G0g==?id=1&name=Carlton&age=23&address=London

Select allOpen in new window

I got the same that you had it...
I think that the blank page without errors is a good sign :)

The problem is, with your url I don't see any activity when I enter it in the browser. Whereas, although I see the error message with my url I see it being entered in my log when I enter it in my browser:

The only difference between your url and my url is the ?

https://projectfunction.azurewebsites.net/api/SaveDataAPI?code=aTqhABAA3TMKEhNRUQSawJnHFHjIUgiL/M8HW/0K4VkYwNk94n5G0g==?id=1&name=Carlton&age=23&address=London

If you enter the following I will see activity in my logs

https://projectfunction.azurewebsites.net/api/SaveDataAPI?code=aTqhABAA3TMKEhNRUQSawJnHFHjIUgiL/M8HW/0K4VkYwNk94n5G0g==&id=1&name=Carlton&age=23&address=London

I GOT IT

I missed out the { }

If someone knows how to add a parameter option as Julian mentioned please let me know

Cheers

Did it work the url settings as I mentioned above?

Hi Leonidas,

Did it work the url settings as I mentioned above?

Unfortunately not..

If you try, nothing will come back

Adding parameters - have not tried but should be a case of entering the values and they are added to the Request body

Missing { } => your code is expecting a JSON post not a urlencoded - I would need to get some more experience points on Azure for being able to say why - but for now it looks like the Request Body needs a valid JSON string to work.

Thanks guys

You are welcome.
