TypeError: Cannot read property 'name' of null NodeJs Request module

Question

我想用请求模块发送一个 post 请求。我的代码是这样截断的：

 let formData = new FormData();

   myArray.map((param, index) => {
      formData.append(param.name, param.value)
    })

    formData.append('file', fs.createReadStream(file.location), { filename: file.name });

    var options = {
      'method': 'POST',
      'url': 'https://shopify-video-production-core-originals.s3.amazonaws.com/',
      'headers': {
      },
      formData: formData,
    };

    let requestProm = async () => {
      return new Promise(resolve => {
        request(options, function (error, response) {
          if (error) {
            logger.error("Video Upload Failed")
            console.log(error)
          } else {
            logger.info("Video Upload Successfull");
            resolve(response);
          }
        })
      })

    }

    await requestProm()

但是我得到一个错误：

TypeError: Cannot read property 'name' of null

为什么我会收到这个错误？请帮忙！

编辑：我控制了我的 formData。没有空名称值。我在互联网上搜索但找不到任何解决方案。所以，我的 formData 是这样的：

Answer 1

Cannot read property '' of null表示对象的属性不存在。您可以做的是记录文件，然后检查属性 'name' 是否存在。记住：console.log() 是你在 nodejs 中最好的朋友（在一般编程中）

Answer 2

显然，表单数据已由请求承诺处理。您可以将表单数据作为对象传递。检查这个

TypeError: Cannot read property 'name' of null NodeJs Request module

TypeError: Cannot read property 'name' of null NodeJs Request module

javascript

multipartform-data

request

node.js
