无法上传大小为>的文件使用REST API到SharePoint的10 mb-400错误请求

问题描述

我们有一个要求，我们需要使用REST API将文件上传到SharePoint 2013(内部部署).  但是下面的代码段上传的文件是< 10mb.对于文件> 10mb，出现错误" 400 Bad Request".有人可以建议， 可以使用REST API上传的最大照片.还有一种方法(使用REST API)上传最大50 mb的文件.

We have a requirement where we need to upload the files to the SharePoint 2013(onpremise) using REST API.  However below code snippet is uploading files <10mb. For files >10mb getting error "400 Bad Request". Can some one suggest, the maximum fize that can be uploaded using REST api. Also is there a way(using REST API) to upload files up to 50 mb.

推荐答案

我建议您在SharePoint 2013中增加最大上传大小.

I suggest you increase the Maximum Upload Size in SharePoint 2013.

以下是一个博客供您参考:
