为什么取得验证码的url,没有参数? about baidupcs HOT 13 CLOSED

未获取到 code_string字符串值吧。 你修改了什么地方？

2014-05-06 4:30 GMT-04:00 terry2010 [email protected]:

pcs -uUSER_NAME quota --urlc
COOKIE FILE: /root/.baidupcs/default.cookie
Password:
Login Failed: Can't get captch image from the server :
https://passport.baidu.com/cgi-bin/genimage?

我发现报错以后, 简单改了一下代码,

url = pcs_utils_sprintf(URL_CAPTCHA "%s", code_string);
img = pcs_http_get_raw(pcs->http, url, PcsTrue, &imgsz); pcs_free(url);
if (!img) {
pcs_set_errmsg(handle, "Can't get captch image from the server : %s",url);
return PCS_NETWORK_ERROR;
}

想看看为什么会出错, 但是 url 是没有参数的, 请问如何修正, 谢谢

pcs_set_errmsg(handle, "Can't get captch image from the server : %s",url);
只是改了下报错的输出, 这里输出的 url 是
https://passport.baidu.com/cgi-bin/genimage?

from baidupcs.

在pcs.c的1587行前，增加代码： printf("html: %s\ncode_string: [%s]\n", html,
code_string); 如下：

             printf("html: %s\ncode_string: [%s]\n", html, code_string);

i = 0;

try_login:
if (code_string[0]) {
res = pcs_get_captcha(pcs, code_string, captch, sizeof(captch));
if (res != PCS_OK) {
pcs_free(token);
pcs_free(code_string);
return res;
}
}

查看输出的html是什么？比较一下html中的code_string值和获取到的code_string值。 没有code_string值表示不需要验证码。

在1660行，同样增加一行printf.

else {
if (code_string) pcs_free(code_string);
code_string = pcs_get_embed_query_token_by_key(html, "&codestring");
printf("html: %s\ncode_string: [%s]\n",
html, code_string);
if (!code_string) {
pcs_set_errmsg(handle, "Can't read the codestring from the
response. Response: %s", html);
pcs_free(token);
pcs_free(code_string);
return PCS_FAIL;
}
}

增加URL输出的地方有问题。换下边这样再输出URL看看。
问题在于：调用pcs_http_get_raw函数的同一行最后有一个pcs_free(url)把url释放掉了。

PcsRes pcs_get_captcha(Pcs handle, const char *code_string, char *captcha,
int captchaSize)
{
struct pcs *pcs = (struct pcs *)handle;
char *url, *img;
size_t imgsz;

captcha[0] = '\0';
if (!pcs->captcha_func) {
pcs_set_errmsg(handle, "No captch function, please regist the function by
call pcs_setopt(handle, PCS_OPTION_CAPTCHA_FUNCTION, pFun).");
return PCS_NO_CAPTCHA_FUNC;
}
url = pcs_utils_sprintf(URL_CAPTCHA "%s", code_string);
img = pcs_http_get_raw(pcs->http, url, PcsTrue, &imgsz);
if (!img) {
pcs_set_errmsg(handle, "Can't get captch image from the server. url: %s",
url);
pcs_free(url);
return PCS_NETWORK_ERROR;
}
if (!(*pcs->captcha_func)((unsigned char *)img, imgsz, captcha,
captchaSize, pcs->captcha_data)) {
pcs_set_errmsg(handle, "Can't get captch from the captcha, which is regist
by user.");
pcs_free(url);
return PCS_GET_CAPTCHA_FAIL;
}
pcs_free(url);
return PCS_OK;
}

增加libcurl错误输出后新的函数：

PcsRes pcs_get_captcha(Pcs handle, const char *code_string, char *captcha, int captchaSize)
{
struct pcs *pcs = (struct pcs *)handle;
char *url, *img;
size_t imgsz;

captcha[0] = '\0';
if (!pcs->captcha_func) {
    pcs_set_errmsg(handle, "No captch function, please regist the function by call pcs_setopt(handle, PCS_OPTION_CAPTCHA_FUNCTION, pFun).");
    return PCS_NO_CAPTCHA_FUNC;
}
url = pcs_utils_sprintf(URL_CAPTCHA "%s", code_string);
img = pcs_http_get_raw(pcs->http, url, PcsTrue, &imgsz); 
if (!img) {
    pcs_set_errmsg(handle, "Can't get captch image from the server. url: %s. Error message: %s", url, pcs_http_strerror(pcs->http));
    pcs_free(url);
    return PCS_NETWORK_ERROR;
}
if (!(*pcs->captcha_func)((unsigned char *)img, imgsz, captcha, captchaSize, pcs->captcha_data)) {
    pcs_set_errmsg(handle, "Can't get captch from the captcha, which is regist by user.");
    pcs_free(url);
    return PCS_GET_CAPTCHA_FAIL;
}
pcs_free(url);
return PCS_OK;

很奇怪，能告知使用什么操作系统、操作系统版本、使用什么编译器、编译器版本、使用的C库吗？

能拿一下最新代码后，再试一下吗？ 再不行的话，我虚拟机装一个64bit系统调试一下。 原因应该是
libcurl的curl_easy_setopt函数传入的值应该是long类型，但是代码中很多地方使用了0和1而不是0L和1L。我改了一下，已经提交到github了，你能帮忙再试一下？
