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", "key":"V1001_TODAY_MUSIC" }, { "type":"click", "name":"歌手简介", "key":"V1001_TODAY_SINGER" }, { "name":"菜单", "sub_button":[ { "type":"click", "name":"hello word", "key":"V1001_HELLO_WORLD" }, { "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"}

curl post sending and receiving

 "bob","key" => "12345"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // post数据 curl_setopt($ch, CURLOPT_POST, 1); // post的变量 curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); $output = curl_exec($ch); curl_close($ch); //打印获得的数据 print_r($output); ?>

  Welcome .
 You are  years old.  

get test

//curl -X GET -H "Content-Type:application/json" -H "Authorization: token 4e56266f2502936e0378ea6a985dc74a5bec4280" http://user.endv.cn/v1/datastreams/plug-status/datapoint/ $url = "http://localhost/web_services.php"; $post_data = array ("username" => "bob","key" => "12345"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); curl_close($ch); //打印获得的数据 print_r($output);

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 d8a1c03fa9e6aaa0a6f4d1e085fe1ce1 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

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
