金山快盤開發（六）

 今天寫的就是測試程序了，其實有些事情是我們想得太難了，一開始後就發現挺簡單的。

頭文件：

#ifndef __KUAIPAN__
#define __KUAIPAN__
void get_signature(char* http_url,char* oauth_consumer_key,char* oauth_nonce, char* oauth_signature_method,char* oauth_timestamp, char* oauth_version,char* consumer_secret,char oauth_signature[]);
size_t write_data(void *ptr, size_t size, size_t nmemb, void *stream); //這個函數是爲了符合CURLOPT_WRITEFUNCTION, 而構造的
#endif

測試主體：

#include <curl/curl.h>
//#include <curl/types.h>
#include <curl/easy.h>
#include <unistd.h>
#include <stdio.h>
#include <string.h>
#include <malloc.h>
#include <stdlib.h>
//const char oauth_nonce
#include "kuaipan.h"
//#include "cJSON.h"

FILE *fp; //定義FILE類型指針
int main(int argc, char *argv[])
{
  char consumer_key[]="你的consumer_key";
  char consumer_secret[]="你的consumer_secret";
  char oauth_signature_method[]="HMAC-SHA1";
  char oauth_signature[2048];
  memset(oauth_signature,0,2048);
  //char request_method[]="GET";
  char http_url1[]="https://openapi.kuaipan.cn/open/requestToken";
  //const char oauth_timestamp;
  char oauth_version[]="1.0";
  char oauth_timestamp[40]="";
  char oauth_nonce[1024]="";
  strcpy(oauth_nonce,(char*)get_nonce());
  sprintf(oauth_timestamp,"%d",(int)time(0));
  //char oauth_signature
  get_signature(http_url1,consumer_key,oauth_nonce,oauth_signature_method, oauth_timestamp, oauth_version,consumer_secret,oauth_signature);


  CURL *curl;
  char url_base[2048]="";
  //strncpy(url_base,http_url1,strlen(http_url1));

  sprintf(url_base,"%s?oauth_signature=%s&oauth_consumer_key=%s&oauth_nonce=%s&oauth_signature_method=HMAC-SHA1&oauth_timestamp=%s&oauth_version=1.0",http_url1,oauth_signature,consumer_key,oauth_nonce,oauth_timestamp);
  printf("%s\n",url_base);
  curl_global_init(CURL_GLOBAL_ALL);
  curl=curl_easy_init();
  curl_easy_setopt(curl, CURLOPT_URL,url_base);

  if((fp=fopen("touch.txt","w"))==NULL)
  {
      curl_easy_cleanup(curl);
      exit(1);
  }
  curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data); //CURLOPT_WRITEFUNCTION 將後繼的動作交給write_data函數處理
  curl_easy_perform(curl);
  curl_easy_cleanup(curl);
  //exit(0);
  return 0;
}
void get_signature(char* http_url,char* oauth_consumer_key,char* oauth_nonce, char* oauth_signature_method,char* oauth_timestamp, char* oauth_version,char* consumer_secret,char oauth_signature[])
{
  //char* oauth_signature=(char*)malloc(1024*sizeof(char));
  char obj[1024]="",d[1024]="",out[1024]="";
  int lk=0,ld=0,t=0;
  //char url[1024]="";
  char consumer_key[1024]="";
  char nonce[1024]="";
  char signature_method[1024]="";
  char timestamp[1024]="";
  char version[1024]="";
  //sprintf(url,"%s&
  sprintf(consumer_key,"oauth_consumer_key=%s",oauth_consumer_key);
  sprintf(nonce,"&oauth_nonce=");
  sprintf(signature_method,"&oauth_signature_method=%s",oauth_signature_method);
  sprintf(timestamp,"&oauth_timestamp=%s",oauth_timestamp);
  sprintf(version,"&oauth_version=%s",oauth_version);

  strcat(d,"GET&");
  //printf("src=%s\n",d);
  //strcat(d,"&",1);
  URLEncode(http_url,strlen(http_url),obj,1024);
  strcat(d,obj);

  URLEncode(timestamp,strlen(timestamp),obj,1024);
  strcat(d,obj);
  URLEncode(version,strlen(version),obj,1024);
  strcat(d,obj);
  printf("src=%s\n%d\n",d,strlen(d));
  ld=strlen(d);
  lk=strlen(consumer_secret);
  char *hmac_shastr=(char*)hmac_sha(consumer_secret,lk,d,ld,out,20);
  int hmac_shalen=strlen(hmac_shastr);
  printf("hmac_shastr=%s\n",hmac_shastr);
  int base64_encodelen=strlen((char*)base64_encode(hmac_shastr, hmac_shalen));
  URLEncode(base64_encode(hmac_shastr,hmac_shalen),base64_encodelen,obj,1024);
  strcat(oauth_signature,obj);
  //strcat(oauth_signature,"\0");
  printf("%s\n%d\n",oauth_signature,strlen(oauth_signature));

  //return oauth_signature;
}


size_t write_data(void *ptr, size_t size, size_t nmemb, void *stream) //這個函數是爲了符合CURLOPT_WRITEFUNCTION, 而構造的
{
    int written = fwrite(ptr, size, nmemb, (FILE *)fp);
    return written;
}

makefile：

obj=kuaipan.o base64.o url_encode.o hmac_sha1.o oauth_nonce.o
kuaipan:$(obj)
    gcc -o kuaipan $(obj) -lcurl

kuaipan.o:kuaipan.c kuaipan.h
    gcc -c kuaipan.c -g
base64.o:base64.c base64.h
    gcc -c base64.c -g
url_encode.o:url_encode.c url_encode.h
    gcc -c url_encode.c -g
hmac_sha1.o:hmac_sha1.c hmac_sha1.h
    gcc -c hmac_sha1.c -g
oauth_nonce.o:oauth_nonce.c oauth_nonce.h
    gcc -c oauth_nonce.c -g
clean:
    rm -f *.o

已經經過測試了，所以應該是沒有問題的，代碼風格可能比較亂。

再編譯時需要libcurl的庫，所以沒有庫的話就會出問題

今天就不上傳代碼了。
