API POST-Request 適用於 PowerShell 但不適用於 Python

Question

我有一個本地 API，我想用非常基本的 POST 請求來測試它。 PowerShell 測試腳本工作得很好，但 Python 測試腳本（應該以相同的方式工作）卻沒有。

---

PowerShell： api_post.ps1

$url = "http://test.local/"

$headers = @{"Content-Type" = "application/json"}

$payload = @(
    @{
        "Order_Number" = "123-vfs"
        "SKU"          = 123
        "Company"      = "Test Ltd"
    }
)

$payload = ConvertTo-Json -InputObject $payload

# Works exactly as it should
Invoke-RestMethod -Uri $url -Method "POST" -Headers $headers -Body $payload

Python api_post.py

import json
import requests

URL = "http://test.local/"

HEADERS = {
    "Content-Type": "application/json"
}

PAYLOAD = [
    {
        "Order_Number": "123-vfs",
        "SKU": 123,
        "Company": "Test Ltd",
    }
]

# Returns an error
requests.post(URL, headers=HEADERS, data=json.dumps(PAYLOAD))

API返回的錯誤沒有意義，因為API仍處於早期測試階段

PS：我沒有在這里標記 PowerShell，因為 PowerShell-example 只顯示 POST 通常有效

Answer 1

requests.post的data參數不接受字符串，您應該直接將 dict 傳遞給它:)

requests.post(URL, headers=HEADERS, data=PAYLOAD[0])
