Use The json data sent by php curl is the same as other data in curl post.

Let me summarize a few examples of json data sent by curl post.

Example 1

$data = array("name" => "Hagrid", "age" => "36");                                                                      
$data_string = json_encode($data);                                                                                     
   
$ch = curl_init('http://api.local/rest/users');                                                                        
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                       
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                        
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                            
    'Content-Type: application/json',                                                                                  
    'Content-Length: ' . strlen($data_string))                                                                         
);                                                                                                                     
   
$result = curl_exec($ch);

Example 2

function http_post_data($url, $data_string) {  
  
        $ch = curl_init();  
        curl_setopt($ch, CURLOPT_POST, 1);  
        curl_setopt($ch, CURLOPT_URL, $url);  
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);  
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(  
            'Content-Type: application/json; charset=utf-8',  
            'Content-Length: ' . strlen($data_string))  
        );  
        ob_start();  
        curl_exec($ch);  
        $return_content = ob_get_contents();  
        ob_end_clean();  
  
        $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);  
        return array($return_code, $return_content);  
    }  
  
$url  = "http://xx.xx.cn";  
$data = json_encode(array('a'=>1, 'b'=>2));  
  
list($return_code, $return_content) = http_post_data($url, $data);

Example 3

$data=' {  
     "button":[  
     {      
          "type":"click",  
          "name":"今日歌曲",

      },  
      {  
           "name":"菜单",  
           "sub_button":[  
            {

            },  
            {  
               "type":"click",  
               "name":"赞一下我们",  
               "key":"V1001_GOOD"  
            }]  
       }]  
 }';  
  
$ch = curl_init($urlcon); //请求的URL地址  
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//$data JSON类型字符串  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data)));  
$data = curl_exec($ch);  
print_r($data);//创建成功返回：{"errcode":0,"errmsg":"ok"}

A brief introduction to the use of curl

Curl is a very powerful http command line tool under Linux, and its functions are very powerful.

1) Without further ado, let’s start from here!

$ curl http://code.endv.cn

After pressing Enter, the html of code.endv.cn will be displayed on the screen~

2) Well, if you want to save the page you have read, should you do this? Woolen cloth?

$ curl http://code.endv.cn > page.html

Of course you can, but it doesn’t have to be so troublesome!

Just use curl's built-in option. To save the http results, use this option: -o

$ curl -o page.html http://code.endv.cn

In this way, you can see a download page progress indicator appear on the screen. When the progress reaches 100%, it will be OK

3) What? ! Can’t access? It must be that your proxy is not configured.

When using curl, you can use this option to specify the proxy server and port used for http access: -x

$ curl -x 123.45.67.89:1080 -o page.html http://code.endv.cn

4) It is annoying when visiting some websites. They use cookies to record session information.

Browsers like IE/NN can certainly handle cookie information easily, but what about our curl? .....

Let’s learn this option: -D

$ curl -x 123.45.67.89:1080 -o page.html -D cookie0001.txt http://code.endv.cn

In this way, when When the page is saved to page.html, the cookie information is also saved to cookie0001.txt

5) So, how to continue to use the cookie information left last time the next time you visit? You know, many websites rely on monitoring your cookie information to determine whether you are visiting their website in violation of the rules.

This time we use this option to append the last cookie information to the http request: -b

$ curl -x 123.45.67.89:1080 -o page1.html -D cookie0002.txt -b cookie0001.txt http://code.endv.cn

In this way, we can simulate almost all IE operations to access the web page !

6) Wait a moment~I seem to have forgotten something~

That’s right! It’s browser information

Some annoying websites always require us to use certain specific browsers to access them. Sometimes, what’s more, we have to use certain specific versions of NND. Where do we have time for it? Go find these weird browsers! ?

Fortunately, curl provides us with a useful option, which allows us to arbitrarily specify the browser information we declare for this visit: -A

$ curl -A "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" -x 123.45.67.89:1080 -o page.html -D cookie0001.txt http://code.endv.cn

In this way, the server receives When requesting access, you will be considered to be an IE6.0 running on Windows 2000. Hey, hey, in fact, maybe you are using a Mac!

And "Mozilla/4.73 [en] (X11; U; Linux 2.2; 15 i686" can tell the other party that you are running Linux on a PC and using Netscape 4.73, hahaha

7) Another commonly used restriction method on the server side is to check the referer for http access. For example, if you visit the homepage first, and then visit the download page specified there, the referer address of the second visit will be the page address after the first successful visit. In this way, as long as the server finds that the referer address of a certain visit to the download page is not the address of the home page, it can conclude that it is a stolen connection ~

hate hate~I just want to steal the connection~! !

Fortunately, curl provides us with the option to set the referer: -e

$ curl -A "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" -x 123.45.67.89:1080 -e "mail.linuxidc.com" -o page.html -D cookie0001.txt http://code.endv.cn

In this way, you can deceive the other party's server. You clicked a link from mail.linuxidc.com. , Hahaha

8) As I write, I find that I have missed something important! ——-Use curl to download files

As I just said, you can use -o to download a page into a file, and the same is true for downloading files. For example,

$ curl -o 1.jpg http://img.endv.cn/~zzh/screen1.JPG

Here we teach you a new option: -O capital O, use it like this:

$ curl -O http://img.endv.cn/~zzh/screen1.JPG

In this way, you can automatically save it locally according to the file name on the server!

One more useful one.

If in addition to screen1.JPG there are screen2.JPG, screen3.JPG, ...., screen10.JPG that need to be downloaded, is it possible that we need to write a script to complete these operations?

Don’t do it!

In curl, just write like this:

$ curl -O http://img.endv.cn/~zzh/screen[1-10].JPG

Hahaha, isn’t it awesome? ! ~

9) Come again, let’s continue to explain downloading!

$ curl -O http://img.endv.cn/~{zzh,nick}/[001-201].JPG

The download generated in this way is

~zzh/001.JPG
~zzh/002.JPG
...
~zzh/201.JPG
~nick/001.JPG
~nick/002.JPG
...
~nick/201.JPG

convenient enough, right? Hahaha

Eh? It's too early to be happy.

Since the file names under zzh/nick are all 001, 002..., 201, the downloaded files have the same name, and the later ones overwrite the previous files ~

没关系，我们还有更狠的！

$ curl -o #2_#1.jpg http://img.endv.cn/~{zzh,nick}/[001-201].JPG

—这是.....自定义文件名的下载？ —对头，呵呵！

这样，自定义出来下载下来的文件名，就变成了这样：原来： ~zzh/001.JPG —-> 下载后： 001-zzh.JPG 原来： ~nick/001.JPG —-> 下载后： 001-nick.JPG

这样一来，就不怕文件重名啦，呵呵

9）继续讲下载

我们平时在windows平台上，flashget这样的工具可以帮我们分块并行下载，还可以断线续传。curl在这些方面也不输给谁，嘿嘿

比如我们下载screen1.JPG中，突然掉线了，我们就可以这样开始续传

$ curl -c -O http://cgi2.tky.3wb.ne.jp/~zzh/screen1.JPG

当然，你不要拿个flashget下载了一半的文件来糊弄我 别的下载软件的半截文件可不一定能用哦 ~

分块下载，我们使用这个option就可以了： -r

举例说明

比如我们有一个http://img.endv.cn/~zzh/zhao1.mp3 要下载（赵老师的电话朗诵 :D ）我们就可以用这样的命令：

$ curl -r 0-10240 -o "zhao.part1" http:/img.endv.cn/~zzh/zhao1.mp3 &\
$ curl -r 10241-20480 -o "zhao.part1" http:/img.endv.cn/~zzh/zhao1.mp3 &\
$ curl -r 20481-40960 -o "zhao.part1" http:/img.endv.cn/~zzh/zhao1.mp3 &\
$ curl -r 40961- -o "zhao.part1" http:/img.endv.cn/~zzh/zhao1.mp3

这样就可以分块下载啦。不过你需要自己把这些破碎的文件合并起来如果你用UNIX或苹果，用 cat zhao.part* > zhao.mp3就可以如果用的是Windows，用copy /b 来解决吧，呵呵

上面讲的都是http协议的下载，其实ftp也一样可以用。用法嘛，

$ curl -u name:passwd ftp://ip:port/path/file

或者大家熟悉的

$ curl ftp://name:passwd@ip:port/path/file

10) 说完了下载，接下来自然该讲上传咯上传的option是 -T

比如我们向ftp传一个文件：

$ curl -T localfile -u name:passwd ftp://upload_site:port/path/

当然，向http服务器上传文件也可以比如

$ curl -T localfile http://img.endv.cn/~zzh/abc.cgi

注意，这时候，使用的协议是HTTP的PUT method

刚才说到PUT，嘿嘿，自然让老服想起来了其他几种methos还没讲呢！ GET和POST都不能忘哦。

http提交一个表单，比较常用的是POST模式和GET模式

GET模式什么option都不用，只需要把变量写在url里面就可以了比如：

$ curl http://code.endv.cn/login.cgi?user=nickwolfe&password=12345

而POST模式的option则是 -d

比如，

$ curl -d "user=nickwolfe&password=12345" http://code.endv.cn/login.cgi

就相当于向这个站点发出一次登陆申请 ~

到底该用GET模式还是POST模式，要看对面服务器的程序设定。

一点需要注意的是，POST模式下的文件上的文件上传，比如

<form method="POST" enctype="multipar/form-data" action="http://img.endv.cn/~zzh/up_file.cgi">
<input type=file name=upload>
<input type=submit name=nick value="go">
</form>

这样一个HTTP表单，我们要用curl进行模拟，就该是这样的语法：

$ curl -F upload=@localfile -F nick=go http://img.endv.cn/~zzh/up_file.cgi

罗罗嗦嗦讲了这么多，其实curl还有很多很多技巧和用法比如 https的时候使用本地证书，就可以这样

$ curl -E localcert.pem https://remote_server

再比如，你还可以用curl通过dict协议去查字典 ~

$ curl dict://dict.org/d:computer
