iPhone data capture tutorial,OKX Wallet Sign up capture data from the source! When we use iPhone on a daily basis, we often encounter some applications that cannot be used normally, such as abnormal connection, slow data transmission, etc. And these problems are likely to be caused by problems with network transmission data. In order to solve these problems, we need to capture the iPhone data, analyze and locate the location of the problem in time, so as to find a solution. This article will introduce in detail how to use the iPhone packet grabbing tool to capture data from the source. I. Preparation work. Before going to catch the bag, we need to prepare some tools and environment. 1. iPhone device First of all, we need a usable iPhone device, as well as a mobile phone number or Wi-Fi network.At the same time, we also need to ensure that the iPhone device is in developer mode, which can be set through Settings -> General -> About This Machine -> Developer. After turning on the developer mode, we can connect the mobile phone through Xcode and carry out debugging operations such as grabbing packages on the device. Two. The bag grabbing tool needs to install the bag grabbing tool to grab bags on iPhone. Here we recommend using the "Charles" or "Wireshark" tool. Both of these tools can be used for iPhone data grabbing packages. The specific usage method will be introduced in detail later. It should be noted that when using Charles to grab bags, the configuration of the computer and mobile phones is required. 3. In order to analyze data on the computer, we need to configure the relevant environment on the computer side.If you use Charles to grab packages, you need to install Charles software and configure it. You can refer to the official document for specific operation. II. Use Charles for iPhone data capture package 1. To install the Charles software, first of all, we need to download and install the Charles package grabbing software on the computer. You can download the latest version from the official website and follow the installation steps to install it. Two. After the installation of the iPhone device is completed, we will connect the iPhone to the computer to ensure that the Charles software has been launched and access the network on the iPhone device. On the interface of Charles software, you will see packet grabbing information similar to the following:![Charles package grabbing interface] (https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fblograndom.cn%2Fwp-content%2Fupl Oads%2F2020%2F07%2Fcharles.png&refer=http%3A%2F%2Fblograndom.cn&app=2002&size=f9999,10000&q=a80&n=0& G=0n&fmt=jpeg? Sec=1637489213&t=21bc852f5825698ab3049420cbe75d04)3.Configure the Charles agent. In order for the Charles packet grabbing software to accurately capture network requests, we need to forward the network requests on the iPhone device to the Charles agent for interception. To configure on iPhone, you can go to Settings -> Wi-Fi, find the currently connected Wi-Fi network, enter the connection details page, set the HTTP agent to manual, and enter the IP address and port number on the Charles software:!

Sec=1637489214&t=5069b9018dcabeea3ddb765bda6a5f5f) At the same time, in the Charles software, you need to turn on the two options "Web Proxy" and "Monitor" so that you can It is enough to intercept requests normally. Four. After the configuration of the packet grabbing operation is completed, we can carry out the data packet grabbing operation.Take Safari as an example, open Safari on your iPhone and visit any website. At this time, Charles will capture the relevant data and display it in the session column of the Charles interface. !

Sec=1637489214&t=d4d06bd3babd4daf60dc2148983cf6cf) We can click on each session to view specific requests and response information in order to better analyze data. III. Use Wireshark for iPhone data capture. In addition to the Charles tool, we can also use Wireshark for iPhone data capture. Here we will also take a look at how to use it. 1. To install the Wireshark software, first of all, we need to download and install the Wireshark package grabbing tool.You can download the latest version from the official website and follow the steps to install it. Two. Connect the iPhone device Connect the iPhone device and the computer to make sure that the device and the computer are in the same Wi-Fi network. Then, open the Wireshark software, click the menu "Capture->Interfaces", select the network interface that needs to be crawled, and then click the "Start" button to start grabbing the package. 3. Open the iPhone device and access the application that needs to be crawled. Wireshark software will intercept and display relevant packets, and we can filter and analyze packets. Similarly, we can also analyze every network request and response in order to find the root cause of the problem.In addition, Wireshark can also set filters to show specific packet details, which is relatively powerful. IV. Summary This article takes Charles and Wireshark as examples to introduce how to use the iPhone data packet grabbing tool to capture network requests and response data from the source in order to better analyze and locate the problem. Of course, in addition, there are other bag-grabbing tools available, which you can choose according to your own needs and actual situation. The most important thing is that grabbing the package is only one of the links to solve the problem. More importantly, analyze the problem according to the packet grabbing data, find the problem, and take corresponding measures to solve the problem.
