在阅读代码前最好可以先花点时间了解一点php 和libcurl的相关知识,并不会花费太长时间,由于我做的时候对php不是特别熟悉,所有使用libcurl拼凑表单的时候出现一个问题,花了我一阵时间去解决。下方代码只是简单的demo,代码有些粗糙,但对于大家的理解应该影响不大

我使用XAMMP中的Apache服务器,php脚本放在\xampp\htdocs\目录下,并在当前目录创建upload文件夹用来存放上传的文件

1:

ReceiveFile.php

文件的类型 */
    $type=array("rar","zip","txt","c","JPG");
 
    /* 获取上传文件信息 */
   // $upfile=&$HTTP_POST_FILES['file'];
    $upfile=$_FILES["file"];
 
    echo "Upload: " . $_FILES["file"]["name"] . "
"; echo "Type: " . $_FILES["file"]["type"] . "
"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb
"; echo "Temp file: " . $_FILES["file"]["tmp_name"] . "
"; /* 获取文件后缀名函数 */ function fileext($filename) { return substr(strrchr($filename, '.'), 1); } //echo "Temp file: " . fileext($upfile['name'] . "
"; /* 判断上传文件类型 */ if( !in_array( strtolower( fileext($upfile['name'] ) ),$type) ) { $text=implode(",",$type); echo "对不起,您只能上传以下类型文件: ",$text,"
"; } else { /* 设置文件名为"日期_文件名" */ $dest=$dest_dir.'/'.date("ymdHis")."_".$upfile['name']; /* 移动上传文件到指定文件夹 */ $state=move_uploaded_file($upfile['tmp_name'],$dest); if ($state) { print("文件上传成功!
"); print("文件名:".$dest."
"); print("上传的文件大小:".( round($upfile['size'] / 1024,2) )." KB
"); } else { /* 处理错误信息 */ switch($upfile['error']) { case 1 : die("上传文件大小超出 php.ini:upload_max_filesize 限制
"); case 2 : die("上传文件大小超出 MAX_FILE_SIZE 限制
"); case 3 : die("文件仅被部分上传
"); case 4 : die("没有文件被上传
"); case 5 : die("找不到临时文件
"); case 6 : die("文件写入失败
"); } } } ?>

2:

upload.html 表单:



可以直接运行upload.html,如http://127.0.0.1/WD/upload.html

则会出现cocos2dx 实现简单的文件上传到php服务器的demo页面,选择相应的文件上传则会提示

注:php页面会有上传大小超过1M的限制

接下来就要最重要的部分了,使用libcurl库来实现upload.html表单,实现上传功能

Httpupload.h

    (curl_easy_setopt)(curl, CURLOPT_CAINFO, ca_certificate_file.c_str());

  struct curl_httppost *formpost = NULL;

       pos != parameters.end(); ++pos) {
    const string &str = pos->first;
    if (str.size() == 0)

}


//重写把数据读入上传数据流函数   
size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp) {
	FILE *fptr = (FILE*)userp;
	size_t m_size = fread(buffer, size, nmemb, fptr);
	return m_size;
} 

在任意地方调用下方代码,则实现E:\\3.0.25.63.zip 文件上传到php服务器的upload目录下
		CCLOG("################################################################################################ Begin send dump file");
		string strPath = "E:\\3.0.25.63.zip";
		std::map parameters;
		string response, error;
		const char * url = "http://127.0.0.1/WD/ReceiveFile.php";
		bool success = HTTPUpload::SendRequest(url,
			parameters,
			strPath.c_str(),
			//"upload_file_minidump",
			"",
			"","","",
			&response,
			NULL,
			&error);




以上代码是个简单的demo,代码相当粗糙,但应该对大家的理解影响不打,代码还有很大的优化空间,大家可以进行优化和扩展空间,期望大家一起完善!
