如何将图像保存到具有Cloudinary的特定文件夹中

Question

我想将图像文件保存在云上的特定文件夹中。文件夹名称为" userimg"。

这是我在没有文件夹的情况下保存的代码。

我的云和文件夹目录。

Answer 1

云上载API支持folder参数。参见-https：//cloudinary.com/documentation/image_upload_api_reference#upload

请尝试添加：

formData.append('folder', 'userimg');

您还可以在公共ID中包含文件夹，例如" myFolder/myimageid"。

另外，请参见：

在云上保存图像文件的代码：

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/normalize/5.0.0/normalize.min.css">
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<div class="container">
    <div class="card">
        <img src="http://fillmurray.com/g/300/300" id="img-preview" />
        <label class="file-upload-container" for="file-upload">
            <input id="file-upload" type="file">
            Select an Image
        </label>
    </div>
</div>
<script>
    var cloudeinary_url = "your_cloudeinary_url";
    var upload_presets = "your_upload_presets";
    var ingpriview = document.getElementById("img-preview");
    var fileupload = document.getElementById("file-upload");
    fileupload.addEventListener('change',
        function (event) {
            var files = event.target.files[0];
            var formData = new FormData();
            formData.append('file', files);
            formData.append('upload_preset', upload_presets);
            formData.append('folder', 'itemimg'); // itemimg is folder name
            axios({
                url: cloudeinary_url,
                method: 'POST',
                header: {
                    'Content-Type': 'application/x-www-form-urlencoded'
                },
                data: formData
            }).then(function (res) {
                document.getElementById("img-preview").src = res.data.secure_url;
                console.log(res);
            }).catch(function (err) {
                console.log(err);
            });
        });
</script>
