问题 I am trying to write a script that fills out forms automatically and then automatically presses the submit button. I have read that you can use curl to post HTTP requests, but what do you do when the form handles the post request with JavaScript, like the code below? <form name="myform" action="javascript:void(0)" method="POST" onsubmit="return fancy_function(this)"> 回答1: Based off your answer to the comments above, what you want to do is not "fill out the form" with curl, but rather post the

问题 Since upgrading to OS X Yosemite 10.10.2, I have been unable to use RCurl to send POSTs via SSL. The error message I get is: Error in function (type, msg, asError = TRUE) : SSLRead() return error -9806 This strongly resembles the curl error here: osx 10.10 Curl POST to HTTPS url gives SSLRead() error So I ran the instructions to install libcurl via home-brew, per the answers on that question, but I cannot figure out how to link RCurl to the new libcurl. curl-config still returns the old

问题 I'm trying to download a file from an FTP server using Curl. I can paste the URL into my browser and it downloads fine. The problem is that with Curl and PHP, I believe the FTP server is doing a redirect and Curl won't follow. I get the error message, "Server denied you to change to the given directory". EDIT: I had %2f in the code and deleted it. That was from a prior test. My code is: $curl = curl_init(); $file = fopen("temp.zip", 'w'); curl_setopt($curl, CURLOPT_URL, "ftp://idx.living.net

问题 In Visual Studio 2012 (SP4) if I create a new Windows EXE solution, use the Nuget command line to "install-package curl", build the solution, the program executes correctly and displays the simple window as expected. If I add a call to curl_version() to the code (meaning the cURL, SSL, etc... DLLs are now referenced) - I get an error from Windows saying... MyProgram.EXE - Entry Point Not Found The procedure entry point CreateFile2 could not be located in the dynamic link library KERNEL32.DLL.

问题 I have a problem trying to download files using libcurl . The program works with multiple threads, every thread that needs to download a file creates a libcurl handle to work with. When the URL is correct everything works, but if there is a mistake in the URL the program crashes. In debug mode, if the URL is not correct curl_easy_perform returns an error connection code and the program works. In contrast, it crashes in release. How could I fix this error? Here is the code that I use to

问题 I am working on a C++ program, which uses cURL lib. When I try to connect to URL, that is incorrect or the page is down I get following error : getaddrinfo(3) failed for www.wp.pl#:80 Couldn't resolve host 'www.wp.pl#' And the program terminates. And that is the problem, because I it to go futher and connect to other pages. I just won't parse and analyze the broken page I don't want to end my program after come across such one.

问题 I have just downloaded and compiled curl. In my /usr/include folder I can see folder, 'curl' and I can see that I do, indeed, have '/usr/include/curl/curl.h'. However I cannot talk XCode into looking there when compiling. #import <curl/curl.h> In my target's properties I have included '/usr/include' to 'Header Search Paths'. The build continues to fail stating that it cannot find 'curl/curl.h' Am I not adding my search paths correctly? Thanks 回答1: User Header Search Paths - searched for

问题 I want to parse the HTML code from a webpage with PHP Curl, but there is an error msg that I can't access the site without JavaScript. Can I enable JavaScript with PHP Curl? 回答1: JavaScript is executed by a browser; cURL does not have a JavaScript parser, therefore can not execute it. Because the website is expecting something to tell it that javascript is enabled, you'll need to use a tool that can execute the webpage through an actual browser to give you the html. 回答2: While a TERRIBLE idea

问题 I'm running python 2.6 on an Intel Mac OS X 10.5 I'm trying to install pycurl 7.16.2.1 (as recommended here http://curl.haxx.se/mail/curlpython-2009-03/0009.html), but for some reason, the installation sees my libcurl 7.16.3, yet it still insist I install 7.16.2 or greater (doesn't 7.16.3 satisfy that?) Here's the error output: Running pycurl-7.16.2.1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-3emZIB/pycurl-7.16.2.1/egg-dist-tmp-K10rbP Using curl-config (libcurl 7.16.3) src/pycurl.c
