Azure函数nodejs : How can I extract the object from the request body in this azure function?

Question

在nodejs azure函数中:

import {
  app,
  HttpRequest,
  HttpResponseInit,
  InvocationContext,
} from "@azure/functions";

export async function workerfunction(
  request: HttpRequest,
  context: InvocationContext
): Promise<HttpResponseInit> {
  context.log(`Http function processed request for url "${request.url}"`);
  context.log("request.body: ", request.body);

我正在 azure 门户中测试:测试体:

{"body":"this is a test message"}

以及打印的消息:

2023-08-02T06:49:19Z   [Information]   request.body:  ReadableStream { locked: true, state: 'closed', supportsBYOB: false }

假设我的请求正文中有一个复杂的对象，其中包含要由我的辅助函数处理的数据，我如何从这个 azure 函数的请求正文中读取该对象？

2023-08-02T06:49:19Z [Information] request.body: ReadableStream { locked: true, state: 'closed', supportsBYOB: false }

问题在于您记录的是 ReadableStream 对象，而不是请求正文中 JSON 对象的实际内容。

• 您直接记录 request.body，它是一个 ReadableStream 对象。需要读取并处理该流才能获取实际内容。

• 检查以下代码，您可以从请求正文中读取并处理 JSON 对象。

更新的代码:

import {
  app,
  HttpRequest,
  HttpResponseInit,
  InvocationContext,
} from "@azure/functions";

export async function workerfunction(
  context: InvocationContext,
  request: HttpRequest
): Promise<HttpResponseInit> {
  context.log(`Http function processed request for url "${request.url}"`);

  try {
    const requestBody = request.body;

    context.log("request.body: ", requestBody);

    // Your processing logic using requestBody

    return {
      status: 200,
      body: "Request processed successfully",
    };
  } catch (error) {
    context.log.error("Error processing request:", error);

    return {
      status: 500,
      body: "Internal server error",
    };
  }
