Python代码：

endpoint = "https://di-myService.cognitiveservices.azure.com/"
key = "ANZ...CzH"

formUrl = "https://raw.githubusercontent.com/Azure-Samples/cognitive-services-REST-api-samples/master/curl/form-recognizer/sample-layout.pdf"

document_intelligence_client = DocumentIntelligenceClient(
            endpoint=endpoint, credential=AzureKeyCredential(key)   
        )

poller = document_intelligence_client.begin_analyze_document(
            "prebuilt-layout", AnalyzeDocumentRequest(url_source=formUrl
        ))

result: AnalyzeResult = poller.result()

在门户中运行这段代码时，我遇到了错误：

连接字符串为空或格式错误

解决方案

这是一个误报。代码在下游阶段失败，因为我在用连接字符串创建Blob客户端时，实际传入的是存储账户名。
