Python常见问题
我能够使用RESTAPI很好地登录（没有证书验证）。然而，当我查询元数据API时，我得到的只是来自graphQL GUI的html/javascript。没有人知道如何正确设置查询以检索与/metadata/graphQL上GUI中显示的相同信息
这是我要登录的代码：
import requests
import json
url = "https://<tableau-server-name>/api/3.8/auth/signin"
payload = json.dumps({
"credentials": {
"personalAccessTokenName": "<my login token>",
"personalAccessTokenSecret": "<my token value>",
"site": {
"contentUrl": ""
}
}
})
headers = {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
response = requests.request("POST", url, headers=headers, data=payload, verify=False)
response = json.loads(response.text)
print(response)
site_id = response['credentials']['site']['id']
user_id = response['credentials']['user']['id']
token = response['credentials']['token']
headers['X-tableau-auth']=token我得到了一个很好的json响应，带有授权令牌，可以传递给后续调用：
{'credentials': {'site': {'id': '<site-id>', 'contentUrl': ''}, 'user': {'id': '<my-user-id>'}, 'token': '<my-user-token>'}}我对元数据api的下一次调用是从这里开始的：
import requests
import json
url = "https://<tableau-server-name>/metadata/graphql/"
payload="{\"query\":\"query getAllTables {\\r\\n workbooks (filter: {id: \\\"<workbook id>"\\\"}) {\\r\\n\\t\\tname\\r\\n dashboards {\\r\\n id\\r\\n name\\r\\n sheets {\\r\\n id\\r\\n name\\r\\n \\tdatasourceFields {\\r\\n id \\r\\n name\\r\\n __typename\\r\\n ...on CalculatedField {\\r\\n formula\\r\\n }\\r\\n }\\r\\n }\\r\\n }\\r\\n }\\r\\n}\",\"variables\":{}}"
headers = {
'\'X-tableau-auth\'': token,
'Accept': 'application/json',
'Content-Type': 'application/json'
}
response = requests.request("GET", url, headers=headers, data=payload)
print(response.text)答复是：

</body>相比之下，我希望查询返回json，并对我在graphql GUI中测试的graphql查询做出相应的响应
我正在运行的graphQL查询如下：
query getAllFields {
workbooks (filter: {id: "<workbook-id>"}){
embeddedDatasources {
fields {
id
name
...on CalculatedField{
formula
}
}
name
id
}
}
}
