Hello

If you use a external API like https://blockchain.info/rawaddr/, the problem is if your make more connections to the same IP in a small time, server blockeds your IP (2 o 3 connections per second is max).
The solution is add sleep instruction.

Code:

import time
...
...
...
for address in addresses:
    urlRequest = urllib2.Request("https://blockchain.info/rawaddr/" + address)
    data = urllib2.urlopen(urlRequest).read()
    json_data = json.loads(data)
    balances.append("Balance of " + address + " is " + str(json_data['final_balance']))
    time.sleep(0.5) # 2 connectios per second

...
...
...

Another solution is connect differents APIs.

Yes, thx

that s the reason I want to use my own node.

But unfortunately i can't reach it from the script.

Still not working?

Can you post your code and/or any error/exception you're getting?

[donGeilo]

Good morning!

lol No still doesn't work!

My code:

Code:

import urllib2

import json



addresses = open("addresses.txt", "r")
balances = open("balances.txt", "w")

for address in addresses:
    urlRequest = urllib2.Request("http://localhost:3001/insight-api/" + address)
    data = urllib2.urlopen(urlRequest).read()
    json_data = json.loads(data)
    balances.write("Balance of " + address + " is " + str(json_data["data"]["balance"]) + "\n") #use the right keys

addresses.close()
balances.close()

My errors:

urllib2.HTTPError: HTTP Error 404: Not Found

Edit:
I think i'm missing something inside the bitcoin.conf file

Edtit2:

Just recognized, seems to be really close! It's the first time the bitcored-Terminal shows the GET requets from python (but with the 404 error in it).
Never appeard before!!!

Good morning!

Good morning to you too (or maybe good evening, or good day )

My errors:

Code:

urllib2.HTTPError: HTTP Error 404: Not Found

If you have this error, then I don't understand why it would work when you enter the url in your browser ... Are you a 100% sure that when you enter http://localhost:3001/insight-api/<address> it works in your browser?

You might try two things:
- Clean your browser's cache and retry (entering the url directly in the browser).
- Add a print statement to see what is actually passed to Request:

Code:

url = "http://localhost:3001/insight-api/" + address
print url

[donGeilo]

Alright,

if i put: localhost:3001/insight/ +address  in the address-bar i get the error 404!

If i just open localhost:3001/insight/  -the page opens an i can put the address in the search field, and it shows me the balance!!!  

EDIT:

I think it supposed to be http://localhost:3001/insight-api/address/ +address

'cause that's the url it shows me if i enter the address in the search field (in fact it shows me"/insight/address/")

Ah! There might be your answer then. If indeed http://localhost:3001/insight-api/address/<address> is the right url then just update the code and see if it works better

[donGeilo]

Nope,
same 404 error

[kaicrypzen]

Nope,

Well you'll just have to figure out what the right url is.

When you put the address in the search field, do you have to click on a search button (or hit enter) ? If so, then what is the url that appears in the search bar once you've done that? This would be the url you should be using.

[donGeilo]

I copy-paste the addres in the search field and hit enter,
and the exact url is:

localhost:3001/insight/address/1NH5FzSuo........

but from the bitcore forum i got the info:
/insight/* is routed via client-side javascript application, the api is accessible at /insight-api/

but from the bitcore forum i got the info:

I found this https://github.com/bitpay/insight-api

It says an address is accessed with:

Code:

/insight-api/addr/<address>

and a balance with:

Code:

/insight-api/addr/<address>/balance

[donGeilo]

If i use:

Code:

 http://localhost:3001/insight-api/addr/+address")

Code:

 http://localhost:3001/insight-api/addr/+address/balance")

i get the error 400 bad request

EDIT:

misstyped in the code!!

Now it is just KeyError: 'data'

So it passsed the url!!!

[donGeilo]

YAY!!!
removed 'data'


and ......

it works!!!!!!!!!!!

But gives no output!!!


EDIT:

SOLVED!!!

[kaicrypzen]

YAY!!!
removed 'data'

That's why I commented

Code:

#use the right keys

and ......

it works!!!!!!!!!!!

But gives no output!!!

The code isn't supposed to give any output ... it just stores balances in balances.txt

EDIT:

SOLVED!!!

Cool , so what was the matter?

[kaicrypzen]

during the tests i edited a few balances -output text files


Just looked into the wrong one!

OK

Balance of 1NH5FzSuo.......
  is 0.1

Do you mean there is a carriage return after the address? If that's the case, then use:

Code:

balances.write("Balance of " + address.strip("\n") + " is " + str(json_data["balance"]) + "\n")

[donGeilo]

No everything works fine, like it should!!

Just one more question:

If my list would contain more lines, like:


John Smith
Address: 1234567890...

Benjamin Franklin
Address: 1098765432.....

How would that look, to just output all balances ?

If you have more info in your text file, maybe you should consider using a csv format or make the lines very distinguishable:

Code:

Name: John Smith
Address: 1234567890...

Then you'll have to test, let's assume that you don't care about the name:

Code:

....

for line in addresses:
    if line.startswith("Address: "): # Test that the line is an address line
        address = line.strip("Address: ") # Remove the prefix Address: 
        urlRequest = urllib2.Request("http://localhost:3001/insight-api/addr/" + address)
        data = urllib2.urlopen(urlRequest).read()
        json_data = json.loads(data)
        balances.write("Balance of " + address + " is " + str(json_data["balance"]) + "\n") 

....

[donGeilo]

Perfect!!!

Thanks alot!!!
