PHP to write a simple app interface _php instance

This is the first PHP interface that the note attempts to write and tries to apply the test in iOS development. Today to share how to write their own interface to test!

I believe many friends have encountered this problem during development: when does the background provide the interface? How do we provide an interface, and when will the other interfaces come out? Without the interface, how can we do it at the front?

Ha ha! After the completion of this chapter, the university can make its own interface to return the fixed dead data to test!

Build PHP Environment

Because I use the computer is a Mac, so recommend that you use Mamp Pro this software, but the fee version, I believe you do not want to spend money will have a way to fix!

Mamp Pro This software is integrated environmental software, has Apache, MySQL, PHP, with the operation of the environment to parse PHP!

If you don't want to use an integrated environment, you can build it yourself. Mac with Apache and PHP environment, only need a little configuration can be used, and then install the MySQL on it!

You can look at the simple version configuration: The new MAC Configuration PHP Development Environment Tutorial this article.

Start the server

Here's how to start the server with Mamp Pro software as an example. In the figure below, we assume that the service address is www.api.com , and then associate the project directory with the service address, and look at the lower-right corner of the graph:

After the environment is started, it can be entered directly into the browser to www.api.com run up!

Start Get interface

After the first run of our empty project, we will automatically generate index.php this file, we delete the contents, and then modify the following:

<?php
 
$data = Array (
  ' tid ' =>, ' 
  name ' => ' Technical blog ', '
  site ' => ' www.huangyibiao.com '); c5/> $response = Array (
  ' code '  =>, 
  ' message ' => ' success for request ',
  ' data '  => $ data,
  );
 
Echojson_encode ($response);

Is our structure here the most common return data structure in the daily app development? They are usually status codes, state information, and client business data.

PHP is also good to force, declare the array, through the json_encode function can output JSON format data!

iOS tune Get interface

We have the server and the interface, so how can the client request and how to get the data? Let's take a look at the simplest GET request example, which uses the Hybnetworking author's Open Source Library:

NSString *url = @ "http://www.api.com/index.php";
[hybnetworkinggetwithurl:urlrefreshcache:yessuccess:^ (ID response) {
  
}fail:^ (nserror *error) {
  
}];

Let's take a look at the results of the iOS client response:

As you can see from the response results, it is consistent with what our server interface returns, looking at the effect of the following image in the browser:

PHP Post Interface

Suppose we want to pass the parameter type over, and the requirement is numeric, used to return different data, when we do interface test, we can do so, do not need to wait for the background to the interface!

<?php
 
$type = $_post[' type '];
$data = ';
 
if (Isset ($type) && is_numeric ($type) && $type >= 0) {
  if ($type = = 1) {
    $data = array (
      ' Ty PE ' => $type, 
      ' name ' => ' Technical blog ', '
      site ' => ' www.huangyibiao.com ');
  } else if ($type = = 2) {
    $ data = Array (
      ' type ' => $type, 
      ' name ' => ' public number: Standard Brother's Technical blog ',
      ' site ' => ' Weixin search: Biaogedejishuboke ');
  } 
 
  $response = Array (
    ' code '  =>, 
    ' message ' => ' success for request ',
    ' data '  => $ data,
    );
 
  Echojson_encode ($response);
  return;
} 
 
$response = Array (
  ' code '  => 999, 
  ' message ' => ' argument error for request ',
  ' data '  = > $data,
  );
 
Echojson_encode ($response);

iOS Tuning Post interface

Here's how the iOS client invokes the PHP post interface just written, which uses the Hybnetworking author's Open Source Library:

NSString *url = @ "http://www.api.com/index.php";
Nsdictionary *params = @{@ "type": @ (1)};
[hybnetworkingpostwithurl:urlrefreshcache:yesparams:paramssuccess:^ (ID response) {
  
}fail:^ (nserror *error) {
  
}];

We look at the results as follows, you can see that the server returned to receive the interface data and parse it out:

Summary

This is the end of this article, I believe that if you want to learn it, we will seriously to operate it again! In fact, before writing this article, the author has tried!

In the future will slowly contact with it, slowly grasp it, will make you work more smoothly!
