在文字识别ocr中,前端可以用js直接去调-增值税发票识别的接口吗?可以的话有没有代码示例?

在文字识别ocr中,前端可以用js直接去调-增值税发票识别的接口吗?可以的话有没有代码示例?我现在只开通了免费的票据凭证识别的OCR服务,还没有那个appcode,然后在这上面调用是成功了的,但是这里的skd没有js的。d6b3a62a98fcb5f963062a5db82d6c71.png

  • 可以看下这个 https://market.aliyun.com/products/57124001/cmapi027758.html#sku=yuncode2175800000 js代码实列可以参考这个。

    var myHeaders = new Headers();
    myHeaders.append("Authorization", "APPCODE xxxx");
    myHeaders.append("Content-Type", "application/json;");

    var raw = "{\"url\":\"https://duguang-mld.oss-cn-hangzhou.aliyuncs.com/data_pool/5b03f08e0426698df86f6afbf42a0142\"}\r\n";

    var requestOptions = {
    method: 'POST',
    headers: myHeaders,
    body: raw,
    redirect: 'follow'
    };

    fetch(, requestOptions)
    .then(response => response.text())
    .then(result => console.log(result))
    .catch(error => console.log('error', error));这是官网的没有sdk 需要自行签名 根据这个示例代码 https://help.aliyun.com/document_detail/469176.html?spm=a2c4g.442329.0.0.6dde4fadBXUEGR。此回答来自钉群【官方】阿里云OCR公共云客户交流群。
