两个 get 请求都会随机给出错误 500，有时它会起作用并给出正确的响应，有时它会给我这个错误。 错误500 VSC 终端

如果我在邮递员上使用 devops URL，则使用本地服务器 url 的邮递员也会发生同样的情况https://dev.azure.com/preet442727/test/_apis/wit/workitems/1?api-version= 7.1 它有效并且每次都给我正确的响应，但不是本地服务器

根据您的 python 应用程序的代码片段，我在示例 hello-world 应用程序中使用

GET

API 进行了测试，它正在工作。 （我添加了

from flask import jsonify

。）

from datetime import datetime
from flask import Flask, render_template, jsonify
from . import app
import os, json
from flask_cors import CORS
from azure.devops.connection import Connection
from msrest.authentication import BasicAuthentication
from azure.devops.v7_1.work_item_tracking.models import Wiql

ORGANIZATION = "MyOrgName"  
PROJECT = "TheProjectName"  
PAT = "xxxxxx"
credentials = BasicAuthentication('', PAT)
connection = Connection(base_url=f"https://dev.azure.com/{ORGANIZATION}", creds=credentials)
wit_client = connection.clients.get_work_item_tracking_client()

@app.route("/work-items", methods=["GET"])
def get_work_items():
    work_item_id = 1  
    work_item = wit_client.get_work_item(work_item_id)      
    try:
        # Get work item by ID
        work_item = wit_client.get_work_item(work_item_id)
        return jsonify(work_item.as_dict())
    except Exception as e:
        return jsonify({"error": "Failed to fetch work item", "details": str(e)}), 500

@app.route("/")
def home():
    return render_template("home.html")

您可以尝试使用另一个脚本进行测试，以帮助确定问题是否是由 Azure DevOps API 本身引起的。

import json
from azure.devops.connection import Connection
from msrest.authentication import BasicAuthentication
from azure.devops.v7_1.work_item_tracking.models import Wiql

ORGANIZATION = "MyOrgName"  
PROJECT = "TheProjectName"  
PAT = "xxxxxx"

credentials = BasicAuthentication('', PAT)
connection = Connection(base_url=f"https://dev.azure.com/{ORGANIZATION}", creds=credentials)
wit_client = connection.clients.get_work_item_tracking_client()

work_item_id = 1  
work_item = wit_client.get_work_item(work_item_id)
print(json.dumps(work_item.as_dict(), indent=4))

如果问题目前已消失，则可能与 Azure DevOps 事件有关。
