在PHP中为Rail PNR API生成HMAC SHA1

Question

I am trying to generate the HMAC SHA1 Hash to use the .

I am using . I used the helper given here .

Then I tried to generate the hash and compare it with the given in the .

But both the hash ie the one I generated and the one I am getting from the are not the same.

Then I tried to use online tools to generate the hash value for the same. But still the hash that is generated is not same as that is coming from the API site.

My three data are in the following way:

• 1234567890
• json
• < >

So the data that has to be hashed is: 1234567890json< > using the < >

I don't know that if the method to generate hash is wrong or if I am doing it wrong. I pretty much followed every step that is stated there correctly.

I am okay if the solution is available in , but is more preferred.

I even read the following but they couldn't help:

Please help me out here...

Thanks.

The values that are to be passed in the API is supposed to be in the alphabetical order. Like in my case above, if we arrange the keys in alphabetical order the will be: and .

So the string to be hashed will be .

Now to generate the hash, basically you can use any PHP function. I use the function to generate the hash.

Now its working for me. Hope this helps anyone who's working with the Rail PNR API.

Thanks.
