# 获取文件上传信息

> 调用本接口可获取文件上传信息,为客户端上传文件至存储空间提供必要的凭证与地址。

调用本接口，获取文件上传信息。

## 接口调用说明

### 说明

* 如果上传文件时提供的入参为spaceId字段，使用[获取文件上传信息](https://open.dingtalk.com/document/development/obtain-storage-upload-information#)接口。
* 如果上传文件时提供的入参为dentryUuid或者uuid字段，推荐使用该文档。

接口的调用流程如下：

步骤一：调用本接口，获取上传文件需要的`resourceUrls`和`headers`参数值。

步骤二：使用OSS的header加签方式上传文件，参考示例：

Java

```java theme={"theme":{"light":"github-light","dark":"github-dark"}}
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
public void test(){
               // 从接口返回信息中拿到resourceUrls
                String resourceUrl = "第一步接口返回的resourceUrls";
              // 从接口返回信息中拿到headers
                Map<String, String> headers = 第一步接口返回的headers;
                URL url = new URL(resourceUrl);
                HttpURLConnection connection = (HttpURLConnection)url.openConnection();
               if (headers != null) {
                for (Map.Entry<String, String> entry : headers.entrySet()) {
                    connection.setRequestProperty(entry.getKey(), entry.getValue());
                }
            }
                connection.setDoOutput(true);
                connection.setRequestMethod("PUT");
                connection.setUseCaches(false);
                connection.setReadTimeout(10000);
                connection.setConnectTimeout(10000);
                connection.connect();
                OutputStream out = connection.getOutputStream();
                InputStream is = new FileInputStream(new File("/Users/xxxxx/Desktop/测试文件.xls"));
                byte[] b =new byte[1024];
                int temp;
                while ((temp=is.read(b))!=-1){
                       out.write(b,0,temp);
                }
                out.flush();
                out.close();
                int responseCode = connection.getResponseCode();
                connection.disconnect();
                if (responseCode == 200) {
                    System.out.println("上传成功");
                 } else {
                    System.out.println("上传失败");
                 }
}
```

Python

```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
#!/usr/bin/env python

import requests

url = '<第一步接口获取的resourceUrl>'
headers = <第一步接口返回的headers>
result = requests.put(url, data=open('<path_to_file>', 'rb'), headers=headers)
print(result)
```

C#

```java theme={"theme":{"light":"github-light","dark":"github-dark"}}
public static string HttpRequest(string url, string filePath, Dictionary<string, string> headers) {

    FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read);
    BinaryReader reader = new BinaryReader(fileStream);
    reader.BaseStream.Seek(0, SeekOrigin.Begin);
    byte[] datas = reader.ReadBytes((int)reader.BaseStream.Length);
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "PUT";
    request.Timeout = 150000;
    foreach (var header in headers) {
        request.Headers.Add($"{header.Key}", $"{header.Value}");
    }
    Stream requestStream = null;
    string responseStr = null;
    try {
        if (datas != null) {
            request.ContentLength = datas.Length;
            requestStream = request.GetRequestStream();
            requestStream.Write(datas, 0, datas.Length);
            requestStream.Close();
        } else {
            request.ContentLength = 0;
        }
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;
        responseStr = response.Headers.GetValues("x-oss-request-id")[0];
    } catch (Exception ex) {
        Console.WriteLine("error");
    } finally {
        request = null;
        requestStream = null;
    }
    return responseStr;
}
```

PHP

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
$url = $result->body->headerSignatureInfo->resourceUrls[0];
$headersSource = $result->body->headerSignatureInfo->headers;
foreach ($headersSource as $key => $value) {
$headers[] = $key . ': ' . $value;
}
// 需要主动指定content-type为空
$headers['Content-Type'] = '';

$file = '/Users/dengxian.ldx/Desktop/test.txt';

$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HEADER => true,
CURLOPT_TIMEOUT => 100,
CURLOPT_CONNECTTIMEOUT => 100,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_PUT => true,
CURLOPT_HTTPHEADER => $headers,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_SSL_VERIFYHOST => false,
));
curl_setopt($ch, CURLOPT_INFILE, fopen($file , 'rb'));
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($file) );
curl_setopt($ch, CURLOPT_UPLOAD, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response .PHP_EOL;
```

Node.js

```javascript theme={"theme":{"light":"github-light","dark":"github-dark"}}
const fs = require('fs');
const request = require('request-promise');

url = <url>;
header = <headers>;

// 注意: 需要主动指定content-type为空
headers['content-type']='';

var options = {
  method: 'PUT',
  url: url,
  headers: headers
};

fs.createReadStream('/Users/dengxian.ldx/temp/test/a.txt').pipe(request(options)).then(body =>{
  console.log(body);
}).catch(err => {
  console.log(err);
});
```

步骤三：调用[提交文件](/zh/open/development/submittal-file)接口，完成文件上传。

### 说明

* 存储空间类型为USER时，空间拥有权限的用户都有操作权限，其他员工调用[添加权限](/zh/open/development/add-permissions-file)接口进行授权。
* 存储空间类型为APP时，任何人操作都需要调用[添加权限](/zh/open/development/add-permissions-file)接口进行授权。
