我有一个我试图在R中连接的模型。我通过运行打开模型;
> library(plumber)
> r <- plumb("deploy_ml_credit_model.R")
Warning message:
In readLines(file) :
incomplete final line found on 'deploy_ml_credit_model.R'
> r$run(swagger = FALSE)
Starting server to listen on port 3582
然后我转到Python并运行以下内容;
Python代码:
import requests
import json
response = requests.post(
“http://127.0.0.1:3582”
, headers={“Content-Type”: “application/json”}
, data=json.dumps({
"Status.of.existing.checking.account": "A11"
, "Duration.in.month": 24
, "Credit.history": "A32"
, "Savings.account.bonds": "A63"
})
)
print response.json()
我在哪里获得以下错误:
File "<ipython-input-41-507692393845>", line 4
“http://127.0.0.1:3582”
^
SyntaxError: invalid character in identifier
我在浏览器中打开链接,我收到此消息:{"error":["404 - Resource Not Found"]}
我哪里错了?我有plumber
在RStudio的后台运行所以它应该连接。我是否有关于权限或防火墙问题的一些问题?
编辑:
当我输入http://127.0.0.1:3582/predict
时,我仍然会收到以下消息 - 错误http://127.0.0.1:3582/predict
。我清理代码,我收到以下错误:
代码2:
import requests
import json
response = requests.post(
"http://127.0.0.1:3582"
, headers={"Content-Type": "application/json"}
, data=json.dumps({
"Status.of.existing.checking.account": "A11"
, "Duration.in.month": 24
, "Credit.history": "A32"
, "Savings.account.bonds": "A63"
})
)
print response.json()
错误2:
File "<ipython-input-49-0669c2ac9d9d>", line 15
print response.json()
^
SyntaxError: invalid syntax
编辑3:
我键入:
print (response)
我得到了这个错误:
<Response [404]>
但R模型正在后台运行
编辑:
使用:
curl -X POST "http://127.0.0.1:8000/__swagger__/predict" -d '{"Status.of.existing.checking.account": "A11", "Duration.in.month": 24, "Credit.history": "A32", "Savings.account.bonds": "A63"}' -H "accept: application/json"
给出了这个错误:
curl -X POST "http://127.0.0.1:8000/__swagger__/predic
t" -d '{"Status.of.existing.checking.account": "A11", "Duration.in.month": 24, "Credit.history":
"A32", "Savings.account.bonds": "A63"}' -H "accept: application/json"

编辑:
我运行这一行:
curl POST -H 'Content-Type:accept:application/json' -d "{/"Credit.history/":/"A32/"}" http://127.0.0.1:8000/__swagger__/predict
所以我决定删除很多我想发送到模型的内容,只删除一个变量,现在我收到了这个错误:
curl POST -H 'Content-Type:accept:application/json' -d "{/"Credit.history/":/"A32/"}" http://127.0.0.1:8000/__swagger__/predict
curl: (6) Could not resolve host: POST
{"error":["500 - Internal server error"],"message":["Error: lexical error: invalid char in json text.\n {/Credit.history/:/A32/}\n

你在字符串中有非常奇怪的引号
“http://127.0.0.1:3582”
- 它们应该是直引号:
"http://127.0.0.1:3582"
您的“错误2”似乎指的是使用Python 3和Python 2语法。 print
是Py3中的常规函数,因此您需要在它周围使用括号:
import requests
import json
response = requests.post(
"http://127.0.0.1:3582",
headers={"Content-Type": "application/json"},
data=json.dumps(
{
"Status.of.existing.checking.account": "A11",
"Duration.in.month": 24,
"Credit.history": "A32",
"Savings.account.bonds": "A63",
}
),
)
print(response.json())
