Salesforce - SharePoint 文件上传 400 错误请求错误

Question

我正在尝试将文件从 Apex 上传到 Sharepoint，但出现“400 错误请求”错误。但是从 JS 代码开始工作。以下是我的代码片段：

1. 顶点代码

Http http = new Http();
HttpRequest httpRequestToSend = new HttpRequest();  
httpRequestToSend.setEndpoint('https://sample.sharepoint.com/sites/siteName/_api/web/GetFolderByServerRelativeUrl(\''+'/sites/siteName/Shared Documents'+'\')/Files/Add(url=\''+'document3.txt'+'\', overwrite=true)');
httpRequestToSend.setMethod('POST');
httpRequestToSend.setHeader('Authorization', 'Bearer ' + token);
httpRequestToSend.setHeader('Content-Type','application/json; odata=verbose');

httpRequestToSend.setBodyAsBlob(Blob.ValueOf('test Message'));
System.debug('***** httpRequestToSend-->' + httpRequestToSend);
Http http1 = new Http();   
HttpResponse httpResponse1 = http1.send(httpRequestToSend);  
System.debug('***** httpResponse-->' + httpResponse1.toString());
    System.debug(httpResponse1.getBody());

2. JS代码

var myHeaders = new Headers();
        myHeaders.append("Authorization", "Bearer " + Token);
        myHeaders.append("Content-Type", "application/json;odata=verbose");

        var requestOptions = {
          method: 'POST',
          headers: myHeaders,
          body: fileBuffer,
        };

        fetch('https://sample.sharepoint.com/sites/siteName/_api/web/GetFolderByServerRelativeUrl(\'/sites/siteName/Shared Documents\')/Files/Add(url=\'test.txt\', overwrite=true)', requestOptions)
          .then(response => response.text())
          .then(result => console.log(result))
          .catch(error => alert('error', error));
      } 

谢谢

根据文档salesforce 无法直接与 FTP 通信，这意味着无法在 FTP 服务器上读取/写入文件。

我也遇到过这个问题，我是这样解决的：-

第 1 步：使用任何语言（C#、Python）创建并托管一个外部 API，该 API 采用两个参数，一个为 fileName，另一个为 fileData，并上传该文件。

Step2：在 Salesforce 端，使用 HttpRequest 使用该 API 并将您的文件作为 filedata 和 fileName.

public void uploadFileToFTP_Service(string fileName,string fileData)
{
    string value='{"fileName":"'+fileName+'","fileData": "'+fileData+'"}';
    HttpRequest req = new HttpRequest();
    req.setEndpoint('http://yourhostedApIPath:9001/data');
    req.setMethod('POST');
    req.setTimeout(120000);        
    req.setHeader('content-type','application/json; charset=utf-8');
    req.setBody(value);        
    Http http = new Http();
    HttpResponse res = http.send(req);
    system.debug('Status code: ' + res.getStatusCode());
}

今天我为此苦苦思索了一段时间，最终通过转义我的相对 url 路径中的空格字符（我希望文件名可能需要相同的解决方法）来克服“400 Bad Request”错误。

每个空格字符 (" ") 必须替换为 ASCII 引用 "%20"

所以在您的示例中，端点 url：

'https://sample.sharepoint.com/sites/siteName/_api/web/GetFolderByServerRelativeUrl(\'/sites/siteName/Shared Documents\')/Files/Add(url=\'test.txt\', overwrite=true)'

应该改为：

'https://sample.sharepoint.com/sites/siteName/_api/web/GetFolderByServerRelativeUrl(\'/sites/siteName/Shared%20Documents\')/Files/Add(url=\'test.txt\', overwrite=true)'

至少就我而言，这解决了问题。
