    　"request_id":4043312669
}

并且也参考了：

http://developer.baidu.com/wiki/index.php?title=docs/pcs/rest/overview

中所解释的POST的例子：

2． POST请求：

说明：

分别用两种方式使用POST方式发送三个参数：key1=value1、key2=value2和key3=value3；方式一与方式二效果等同。

方式一：

POST /rest/2.0/pcs/quota?key2=value2&key3=value3 HTTP/1.1

User-Agent: curl/7.12.1 (x86_64-redhat-linux-gnu) libcurl/7.12.1 OpenSSL/0.9.7a zlib/1.2.1.2 libidn/0.5.6

方式二：

value2
------WebKitFormBoundaryS0JIa4uHF7yHd8xJ

value3
------WebKitFormBoundaryS0JIa4uHF7yHd8xJ--

然后用代码：

string[] token = respTokenJson.Split(',');

string tokenStr = token[2].Split(':')[1].Trim('"');

byte[] fileBytes = null;
string filename = "fileForUpload2.txt";
string fullFilePath = @"d:\" + filename;
using (FileStream fs = new FileStream(fullFilePath, FileMode.Open))
{
    fileBytes = new byte[fs.Length];
    fs.Read(fileBytes, 0, fileBytes.Length);
}

StringBuilder buffer = new StringBuilder();
char[] fileCh = new char[fileBytes.Length];
for (int i = 0; i < fileBytes.Length; i++)
    fileCh[i] = (char)fileBytes[i];

buffer.Append(fileCh);
//postDict = new Dictionary<string, string>();
//postDict.Add("file", buffer.ToString());

string postDataStr = buffer.ToString();

string uploadSingleFileUrl = "https://pcs.baidu.com/rest/2.0/pcs/file?";
Dictionary<string, string> queryParaDict = new Dictionary<string, string>();
queryParaDict.Add("method", "upload");
queryParaDict.Add("access_token", tokenStr);
queryParaDict.Add("path", "/apps/测试应用/" + filename);
uploadSingleFileUrl += crifanLib.quoteParas(queryParaDict);

curCookies = crifanLib.getCurCookies();
newCookies = new CookieCollection();
foreach (Cookie ck in curCookies)
{
    if (ck.Name == "BAIDUID" || ck.Name == "BDUSS")
    {
        ck.Domain = "pcs.baidu.com";
    }

    newCookies.Add(ck);
}
crifanLib.setCurCookies(newCookies);

string boundaryValue = "----WebKitFormBoundaryS0JIa4uHF7yHd8xJ";
string boundaryExpression = "boundary=" + boundaryValue;

headerDict = new Dictionary<string, string>();
headerDict.Add("Pragma", "no-cache");
headerDict.Add("Content-Type", "multipart/form-data;" + " " + boundaryExpression);

postDataStr = boundaryValue + "\r\n" 
            + "Content-Disposition: form-data; name=\"file\"" + "\r\n" 
            + postDataStr + "\r\n" 
            + boundaryValue;

//string str = crifanLib.getUrlRespHtml(
//    string.Format(@"https://pcs.baidu.com/rest/2.0/pcs/file?method=upload&path=%2Fapps%2F%E6%B5%8B%E8%AF%95%E5%BA%94%E7%94%A8%2F78.jpg&access_token={0}", tokenStr),
//    headerDict, postDict);
string respJson = crifanLib.getUrlRespHtml(uploadSingleFileUrl, headerDict, null, null, postDataStr: postDataStr);

结果出错，出现403：

【解决过程】

1。很明显，403是就是禁止访问，一般都是权限错误。

但是此处确保对应的access_token等值是正常的，即没有权限方面的错误的。

2.百度官网：

http://developer.baidu.com/wiki/index.php?title=docs/cplat/stor/faq

也说了，403的话，是：

返回403是什么意思？

这种情况一般是权限验证没有通过。可能有如下几种情况：

没有权限访问资源。
签名计算错误。可查看是否计算签名的对象有多少是正确的。

3.后来别处调试的结果，貌似也是如预期的：

4.然后调试发现，此时的request header是，正常的：

{Accept: */*

User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3; .NET4.0C; .NET4.0E

Accept-Encoding: gzip, deflate,gzip

Content-Type: multipart/form-data; boundary=—-WebKitFormBoundaryS0JIa4uHF7yHd8xJ

Host: pcs.baidu.com

Cookie: $Version=1; BAIDUID=6D174687C22FA05F53A9DB633FC499D8:FG=1; $Path=/; BDUSS=5JTlV4aEMyMTJnc2hxYkpud3JFTldlMC02cjdRUHJXcGEtRnpXVmJoaWVSN05SQVFBQUFBJCQAAAAAAAAAAAEAAAAZP0gCYWdhaW5pbnB1dDMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAJ66i1GeuotRNH

Content-Length: 180

Expect: 100-continue

Connection: Keep-Alive

}

以及对应的post data是：

"—-WebKitFormBoundaryS0JIa4uHF7yHd8xJ

Content-Disposition: form-data; name="file"

6222021102008788781

home abc:

6228480670539546416

—-WebKitFormBoundaryS0JIa4uHF7yHd8xJ"

也符合其规范的。

但是结果就是不对，始终是403错误。

5.再去试试，把所有的，当然的cookie，都改为此处的domain：

curCookies = crifanLib.getCurCookies();
newCookies = new CookieCollection();
foreach (Cookie ck in curCookies)
{
    //if (ck.Name == "BAIDUID" || ck.Name == "BDUSS")
    //{
        ck.Domain = "pcs.baidu.com";
    //}

    newCookies.Add(ck);
}
crifanLib.setCurCookies(newCookies);

试试效果。

结果还是错误依旧。

6.后来又试了试：

string[] token = respTokenJson.Split(',');

string tokenStr = token[2].Split(':')[1].Trim('"');

byte[] fileBytes = null;
string filename = "fileForUpload2.txt";
string fullFilePath = @"d:\" + filename;
using (FileStream fs = new FileStream(fullFilePath, FileMode.Open))
{
    fileBytes = new byte[fs.Length];
    fs.Read(fileBytes, 0, fileBytes.Length);
}

StringBuilder buffer = new StringBuilder();
char[] fileCh = new char[fileBytes.Length];
for (int i = 0; i < fileBytes.Length; i++)
    fileCh[i] = (char)fileBytes[i];

buffer.Append(fileCh);
//postDict = new Dictionary<string, string>();
//postDict.Add("file", buffer.ToString());

string fileDataStr = buffer.ToString();

string uploadSingleFileUrl = "https://pcs.baidu.com/rest/2.0/pcs/file?";
Dictionary<string, string> queryParaDict = new Dictionary<string, string>();
queryParaDict.Add("method", "upload");
queryParaDict.Add("access_token", tokenStr);
//queryParaDict.Add("path", "/apps/测试应用/" + filename);
//queryParaDict.Add("path", "/apps/测试应用/");
uploadSingleFileUrl += crifanLib.quoteParas(queryParaDict);

curCookies = crifanLib.getCurCookies();
newCookies = new CookieCollection();
foreach (Cookie ck in curCookies)
{
    //if (ck.Name == "BAIDUID" || ck.Name == "BDUSS")
    //{
        ck.Domain = "pcs.baidu.com";
    //}

    newCookies.Add(ck);
}
crifanLib.setCurCookies(newCookies);

string boundaryValue = "----WebKitFormBoundaryS0JIa4uHF7yHd8xJ";
string boundaryExpression = "boundary=" + boundaryValue;

headerDict = new Dictionary<string, string>();
headerDict.Add("Pragma", "no-cache");
headerDict.Add("Content-Type", "multipart/form-data;" + " " + boundaryExpression);

string postDataStr = "";
postDataStr += boundaryValue + "\r\n" 
            + "Content-Disposition: form-data; name=\"Filename\"" + "\r\n"
            + filename + "\r\n";
postDataStr += boundaryValue + "\r\n"
            + "Content-Disposition: form-data; name=\"path\"" + "\r\n"
            + "/apps/测试应用/" + "\r\n";
postDataStr += boundaryValue + "\r\n"
            + "Content-Disposition: form-data; name=\"Filedata\"; filename=\"" + filename + "\" \r\n"
            + "Content-Type: application/octet-stream" + "\r\n"
            + fileDataStr + "\r\n"
            + boundaryValue;
//postDataStr += boundaryValue + "\r\n" 
//            + "Content-Disposition: form-data; name=\"file\"" + "\r\n" 
//            + fileDataStr + "\r\n" 
//            + boundaryValue;

//string str = crifanLib.getUrlRespHtml(
//    string.Format(@"https://pcs.baidu.com/rest/2.0/pcs/file?method=upload&path=%2Fapps%2F%E6%B5%8B%E8%AF%95%E5%BA%94%E7%94%A8%2F78.jpg&access_token={0}", tokenStr),
//    headerDict, postDict);
string respJson = crifanLib.getUrlRespHtml(uploadSingleFileUrl, headerDict, null, null, postDataStr: postDataStr);

结果错误依旧。

6.后来，参考：

http://developer.baidu.com/wiki/index.php?title=docs/pcs/guide/usage_example

以为，找到了之前的错误，然后去访问自己的：

https://openapi.baidu.com/oauth/2.0/authorize?response_type=token&client_id=Gnwa0TAyuWHccReOq7DRVNDe&redirect_uri=oob&scope=netdisk

可以看到所需要的界面，可以获得百度网盘创建文件夹并修改的那个权限了。

然后可以访问到：

http://openapi.baidu.com/oauth/2.0/login_success#expires_in=2592000&access_token=3.60b12647a72d958bf77e07a4d58b8d93.2592000.1370768746.1057380247-758730&session_secret=bf7dcf9ac8517657623af68c8735b7ba&session_key=94rlZwL7wihABheINcMLcJGK0a0f5hNaPSkftNRqEAp7vzHcfXDEjcsok9AMTkY%2FcpakCCn5hwXkm5xaGWWg72gJkwtA%2FNM%3D&scope=basic+netdisk

对应的网页显示的是“百度 OAuth2.0”的那个界面了。

然后可以获得对应的：

access_token=3.60b12647a72d958bf77e07a4d58b8d93.2592000.1370768746.1057380247-758730

然后就再去写对应的代码：

            string respJson = crifanLib.getUrlRespHtml(uploadSingleFileUrl, headerDict, null, null, postDataStr: postDataStr);

        }
    }
}

结果是，还是同样的403的错误，彻底无语了。

解决了没？

The12年前 (2013-10-05)回复

没。因为后来也懒得去弄了。即使可以解决，也懒得弄了。

queryParaDict.Add("path", "/apps/测试应用/" + filename); 路径错了，把“/测试应用”改为pcs api开启时创建的文件夹名（也就是你的应用）

syzll12年前 (2013-09-11)回复

谢谢提醒。不过这点，是很容易想到的事情，当时就试过了，还是不行的。当时专门另外创建几个文件夹，并且改为对应的文件夹的。都不行。你的是成功的？

- 你这篇文章在我学习百度云API时搜到的，那时候是返回的用户请求错误，是上传POST表单错了，你这个403的错误没有出现过，你写的这个语言我不懂，我的是用易语言写的，可以上传成功。解决方法：你可以先写个简单的，直接用get方式访问“https://pcs.baidu.com/rest/2.0/pcs/quota?method=info&access_token=你的access_token”看看能不能获取正确返回的信息。

第一个请求地址中需要指定scope=netdisk

yecheng12年前 (2013-08-29)回复

我的代码中： //1. access https ... string getNetdiskTokenUrl = "https://openapi.baidu.com/oauth/2.0/authorize?response_type=token&client_id=" + txbBaiduApiKey.Text + "&redirect_uri=oob&scope=netdisk"; 不是已经指定了吗？？？

我也遇到了，怎么也没行，难道这个就是个摆设？我的QQ :165609409 欢迎交流

sutong13年前 (2013-07-01)回复

是利用百度提供的那个api搞定的？
crifan13年前 (2013-07-03)回复

我也是各种错误，怎么上传也是成功，可以加为QQ好友吗？我的QQ是714715047

上传单个文件
