api - Google Vision Api 支持 PDF 和 TIFF 文本检测，但它也可以与包含图像的 PDf 一起使用吗？

问题描述

我正在尝试使用包含图像的 pdf 以及 google vision API，但它会引发以下错误：

下午 4:35:12.207 info dialogflowFirebaseFulfillment Dialogflow 请求标头：{"host":"us-central1-detecttext-5a0c3.cloudfunctions.net","user-agent":"Apache-HttpClient/4.5.4 (Java/1.8. 0_181)","传输编码":"chunked","accept":"text/plain, /x-macromania, x-macsymbol, x-macthai, x-macturkish, x-macukraine, x-ms932_0213, x-ms950-hkscs, x-ms950-hkscs-xp, x-mswin-936, x-pck, x- sjis_0213, x-utf-16le-bom, x-utf-32be-bom, x-utf-32le-bom, x-windows-50220, x-windows-50221, x-windows-874, x-windows-949, x-windows-950, x-windows-iso2022jp","内容类型":"应用程序/json; charset=UTF-8","function-execution-id":"dvrpphf9f855","x-appengine-api-ticket":"4b7e84f29e9ce22b","x-appengine-city":"?","x-appengine- citylatlong":"0.000000,0.000000","x-appengine-country":"US","x-appengine-https":"on","x-appengine-region":"?","x-appengine-用户 IP":"35.193.50.245","x-cloud-trace-context":"

解决方案

我有同样的问题 - 在我的情况下，gzip: true上传设置导致问题：

this.client
    .bucket(bucketName)
    .upload(fullPath, {
        gzip: false,  // setting gzip: true causes the pdf annotator to fail
        metadata: {
            cacheControl: 'no-cache',
        },
    })
    .then(...)
