在PHP中遇到preg_match（）问题[关闭](Having an issue with preg_match() in PHP [closed])

 这里混合了两种不同的API约定。 使用Shared API时不使用run上下文，它仅在调用Word API时使用 。 一般来说，我会推荐使用Word API，因为它更新，整体上提供了更多的功能。 
 
 也就是说，对于此操作，您可以使用Word或Shared API。 我将提供两个例子。 
 
 还要注意.toDataURL()返回一个包含 base64图像的字符串。 它不是纯粹的base64表示。 您需要删除Word之前的data:image/png;base64,前缀才能够呈现它。 
 
 共享API： 
 
 既然你只是插入一个图像，我会使用Office.CoercionType.Image而不是Office.CoercionType.Html ： 
 
Office.context.document.setSelectedDataAsync(imgHtml, {
        coercionType: "image"
    },
    function (asyncResult) {
        if (asyncResult.status == "failed") {
            writeError('Error: ' + asyncResult.error.message);
        }
    });
 
 Word API： 
 
 Word API包含一个insertInlinePictureFromBase64方法。 与setSelectedDataAsync ，它将图像作为Base 64编码的字符串： 
 
Word.run(function (context) {
    context.document.body.insertFileFromBase64(base64String, "end");
    return context.sync();
}).catch(function (myError) {
    // Handle error
})

You're mixing a two different API conventions here. You don't use a run context when using the Shared API, it is only used when calling the Word API. In general, I would recommend using Word API as it's newer and overall provides a more functionality. 
 
That said, for this operation you could use either Word or Shared APIs. I'll provide examples for both.
 
Also note that .toDataURL() returns a string that includes a base64 image. It isn't a pure base64 representation. You need to remove the data:image/png;base64, prefix before Word will be able to render it. 
 
Shared API:
 
Since you're simply inserting an image, I would use Office.CoercionType.Image instead of Office.CoercionType.Html:
 
Office.context.document.setSelectedDataAsync(imgHtml, {
        coercionType: "image"
    },
    function (asyncResult) {
        if (asyncResult.status == "failed") {
            writeError('Error: ' + asyncResult.error.message);
        }
    });
 
Word API:
 
The Word API includes a insertInlinePictureFromBase64 method. As with the setSelectedDataAsync, it takes an image in as a Base 64 encoded string:
 
Word.run(function (context) {
    context.document.body.insertFileFromBase64(base64String, "end");
    return context.sync();
}).catch(function (myError) {
    // Handle error
})
