什么是WebDav

What is WebDAV?

Briefly: WebDAV stands for “Web-based Distributed Authoring and Versioning”. It is a set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers.

WebDAV Resources

WebDav是基于HTTP的协议，他可以允许客户端远程编辑Web内容。

WebDAV的特性和优势

支持创建、修改、复制、移动、移除、查询、列举文件

文件锁

版本控制

支持修改文件属性

安全完善的身份验证机制

支持https加密

支持proxy

客户端缓存

方便的客户端工具：和局域网中的文件共享一样简单使用。

WebDav常用命令

WebDav在HTTP的基础上扩展了自己的命令，例如：

PROPFIND 用于获取文件夹列表、文件夹内的文件列表、文件夹和文件的属性；

MKCOL 用于创建空文件夹；

PUT 用于上传文件；

GET 用于下载文件；

COPY 用于复制文件；

MOVE 用于移动文件；

WebDav常用命令的测试（代码）

我在坚果云网盘中，创建了几个文件夹，上传了几个文件。并按照如何在Zotero中设置webdav连接到坚果云？进行了网盘的WebDav服务配置，生成了WebDav密码。

根据学习WebDav ，直接在windows cmd使用curl命令就可以一定程度测试WebDav，我这里是在VS 2022中，通过libcurl库，向坚果云发送请求。

关于VS中如何导入libcurl库，可以看[libcurl] windows visual studio 导入libcurl库。

PROPFIND 方法测试

代码：

<code>#include <curl/curl.h>

#include <iostream>

#include <fstream>

using std::cout;

using std::endl;

using std::ios;

#define ERROR(X) (cout << __FUNCDNAME__ << " " << (X) << " " << "error" << endl, -1)

#define ERROR2(X,Y) (cout << __FUNCDNAME__ << " " << (X) << " " << (Y) << " " << "error" << endl, -1)

#if 1 // WebDav

size_t write_callback(char* ptr, size_t size, size_t nmemb, void* userdata);

int My_PROPFIND();

FILE* fp;

int main()

{

//打开一个文件，用于输出WebDav响应

char filename[256];

sprintf_s(filename, 256, "%s.%s", "WebDav-Test", "xml");

errno_t err = fopen_s(&fp, filename, "wb");

if (err)

return ERROR2("fopen_s", err);

//初始化curl

curl_global_init(CURL_GLOBAL_WIN32);

//WebDav请求函数

My_PROPFIND();

curl_global_cleanup();

cout << "program end." << endl;

}

int My_PROPFIND()

{

const char* host = "https://dav.jianguoyun.com";

list = curl_slist_append(list, "Accept: */*");

curl_easy_setopt(curl, CURLOPT_HTTPHEADER, list);

//指定用于SSL证书验证的证书

CURLcode err = curl_easy_setopt(curl, CURLOPT_CAINFO, "D:\\SourceCode\\cert\\_.jianguoyun.com.crt");

if (err != CURLE_OK) {

cout << "CURLOPT_CAPATH err:" << err << endl;

}

//如果不设置，会出现：unable to get local issuer certificate的错误

curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);

//执行HTTP请求

CURLcode ret = curl_easy_perform(curl);

if (ret != CURLE_OK) {

curl_easy_cleanup(curl);

fclose(fp);

return ERROR2("curl_easy_perform", ret);

}

}

else {

fclose(fp);

return ERROR("curl_easy_init");

}

fclose(fp);

curl_easy_cleanup(curl);

return 0;

}

size_t write_callback(char* ptr, size_t size, size_t nmemb, void* userdata)

{

int realsize = size * nmemb;

fwrite(ptr, 1, realsize, fp);

return realsize;

}

#endif

控制台输出：

我对Dav中的box1文件夹发送了PROPDIND请求，在响应回来的XML内容中，列出了box1中的每个文件夹和文件（包括box1自己）。每个<d:response>节点都包含了一个文件夹或者文件，<d:response>节点，是文件夹或者文件的属性信息。

PUT 方法测试

只保留方法部分，其余代码省略。

int My_PUT()

{

//这里需要指明需要在Dav上创建的文件的路径“box1”和名字“Upload_test.txt”

curl_easy_setopt(curl, CURLOPT_READDATA, src);//设置传入回调函数的文件句柄

curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);//设置文件大小

//指定用于SSL证书验证的证书

}

{

FILE* src = (FILE*)userdata;

/* copy as much data as possible into the 'ptr' buffer, but no more than

'size' * 'nmemb' bytes */

size_t retcode = fread(ptr, size, nmemb, src);

return retcode;

}

PROPPATCH方法

PROPPATCH方法用于修改文件的属性。

WebDav方法的HTTP Body是XML格式，前面尝试的几个请求都没有添加Body。

PROPPATCH需要在Body中添加需要修改的属性指令。

以刚才PUT的文件Upload_test.txt为目标，把它的<d:displayname>修改为Upload_test_1.txt。

但是没有效果，坚果云给的响应中消息中，也没有显示失败信息。

我咨询了坚果云的客服，客服联系技术给出了回复，目前坚果云不支持PROPPATCH方法

因此，无法验证我的代码是否正确，但是还是记录一下代码，期待以后有机会验证。
