Hello group. I’m testing Orthanc’s Api Rest, but I’m having trouble using / tools / find. With curl (on linux or windows) it works fine, but not with python. Code:

import requests
from requests.auth import HTTPBasicAuth
data = ‘{“Level”:“Study”,“Query”:{“PatientName”:“BRAINIX”},“Expand”:true}’
url = “http://localhost:8042/tools/find -d”
response = requests.get(url + ’ '’ +data + '' ', auth=HTTPBasicAuth(‘alice’, ‘luisPassword’))

print(response.text)

Response:
{
“HttpError” : “Not Found”,
“HttpStatus” : 404,
“Message” : “Unknown resource”,
“Method” : “GET”,
“OrthancError” : “Unknown resource”,
“OrthancStatus” : 17,
“Uri” : "/tools/find -d ‘{"Level":"Study","Query":{"PatientName":"BRAINIX"},"Expand":true}’ "
}

with curl (on linux):
curl -u alice:alicePassword http://localhost:8042/tools/find -d ‘{“Level”:“Study”,“Query”:{“PatientName”:“BRAINIX”},“Expand”:true}’
and curl on windows:
curl -u alice:alicePassword http://localhost:8042/tools/find -d ‘{"Level":"Study","Query":{"PatientName":"BRAINIX"},"Expand":true}’

Response (OK):
{

Hello,

Here is a full working sample:

import json
import pprint
import requests
from requests.auth import HTTPBasicAuth

data = {
“Level”:“Study”,
“Query”:{“PatientName”:“BRAINIX”},
“Expand”:True
}

response = requests.post(‘http://localhost:8042/tools/find’,
json.dumps(data),
auth = HTTPBasicAuth(‘alice’, ‘luisPassword’))

pprint.pprint(json.loads(response.content))

Regards,
Sébastien-

Please excuse me again with another question.
But I want to list the studies of a patient, but I can’t do it. Please could you help me.
Code:

import pprint
import json
import requests

from requests.auth import HTTPBasicAuth
uspw = HTTPBasicAuth(‘alice’, ‘luisPassword’)

data = {
“Level”:“Study”,
“Query”:{“PatientName”:“BRAINIX”},
“Expand”:True
}

response = requests.post(‘http://localhost:8042/tools/find’,
json.dumps(data),
auth = uspw)

response_json = json.loads(response.json)
pprint.pprint(response_json)

for patient in response_json[‘ID’]:
print(‘Study Date:’, patient[‘LastUpdate’])
print(‘Name:’, patient[‘PatientName’])
print(‘Study:’, patient[‘StudyDescription’])
print(‘DOB:’, patient[‘PatientBirthDate’])
print(‘’)

Result:
TypeError: list indices must be integers or slices, not str

Thank you

Here is a corrected version of your script (modifications are highlighted in bold):

import pprint
import json
import requests

from requests.auth import HTTPBasicAuth
uspw = HTTPBasicAuth(‘alice’, ‘luisPassword’)

data = {
“Level”:“Study”,
“Query”:{“PatientName”:“BRAINIX”},
“Expand”:True
}

response = requests.post(‘http://localhost:8042/tools/find’,
json.dumps(data),
auth = uspw)

response_json = json.loads(response.content)
pprint.pprint(response_json)

for patient in response_json:
print(‘Study Date:’, patient[‘LastUpdate’])
print(‘Name:’, patient[‘PatientMainDicomTags’][‘PatientName’])
print(‘Study:’, patient[‘MainDicomTags’][‘StudyDescription’])
print(‘DOB:’, patient[‘PatientMainDicomTags’][‘PatientBirthDate’])
print(‘’)

Thank you. You are very kind.
The code worked perfectly.
