【问题】
参考百度API的官网：
http://developer.baidu.com/wiki/index.php?title=docs/pcs/rest/file_data_apis_list
中的“上传单个文件”的解释：
上传单个文件API演示 功能 上传单个文件。 百度PCS服务目前支持最大2G的单个文件上传。 HTTP请求方式 POST URL https://pcs.baidu.com/rest/2.0/pcs/file 请求参数 参数名称 类型 是否必需 描述 method string 是 固定值，upload。 access_token string 是 开发者准入标识，HTTPS调用时必须使用。 path string 是 上传文件路径（含上传的文件名称)。 注意：
file char[] 是 上传文件的内容。 ondup string 否
注意：
返回参数 参数名称 类型 UrlEncode 描述 path string 是 该文件的绝对路径。 size uint64 否 文件字节大小。 ctime uint64 否 文件创建时间。 mtime uint64 否 文件修改时间。 md5 string 否 文件的md5签名。 fs_id uint64 否 文件在PCS的临时唯一标识ID。 示例 请求示例: POST https://pcs.baidu.com/rest/2.0/pcs/file?method=upload&path=%2fapps%2falbum%2f1.JPG&access_token=b778fb598c717c0ad7ea8c97c8f3a46f 响应示例： {
"path" : "/apps/album/1.jpg",
"size" : 372121,
"ctime" : 1234567890,
"mtime" : 1234567890,
"md5" : "cb123afcc12453543ef",
"fs_id" : 12345,
"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：
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 Pragma: no-cache Accept: */* Host:pcs.baidu.com Content-Length:123 Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryS0JIa4uHF7yHd8xJ ------WebKitFormBoundaryS0JIa4uHF7yHd8xJ Content-Disposition: form-data; name="key1" value1 ------WebKitFormBoundaryS0JIa4uHF7yHd8xJ— 方式二： POST /rest/2.0/pcs/quota 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 Pragma: no-cache Accept: */* Host:pcs.baidu.com Content-Length:123 Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryS0JIa4uHF7yHd8xJ ------WebKitFormBoundaryS0JIa4uHF7yHd8xJ Content-Disposition: form-data; name="key1" value1 ------WebKitFormBoundaryS0JIa4uHF7yHd8xJ Content-Disposition: form-data; name="key2" value2 ------WebKitFormBoundaryS0JIa4uHF7yHd8xJ Content-Disposition: form-data; name="key3" value3 ------WebKitFormBoundaryS0JIa4uHF7yHd8xJ-- |
然后用代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 | 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();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：
|
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：
1 2 3 4 5 6 7 8 9 10 11 12 | 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：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 | 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();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：
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：
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：

结果是，还是同样的403的错误，彻底无语了。
