SDK Interface Linux Environment Deployment ​

Before calling, you must use ldd libShellExport.so, ldd libFTDataInterface.so and ldd hqdatafeed in the decompressed interface directory to check whether the environment on which the interface library depends is complete. If it is not complete, please use yum or apt-get to install (the following instructions take Ubuntu environment as an example), as follows:

Centos: sudo yum install -y libgcc.i686 zlib.i686 glibc.i686 libstdc++-devel.i686
Ubuntu: sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386

1)If the following 'not found' error occurs, install according to the missing error

2)Common missing libidn.so.11 error installation

You can search libidn and install:

查找：apt-cache search libidn  
安装：sudo apt install libidn-dev

After installation, such as ldd libFTDataInterface.so to check whether the environment depends or is missing, it may be that the installation location is wrong.

After installation, such as ldd libFTDataInterface.so to check whether the environment depends or is missing, it may be that the installation location is wrong. Search for:

sudo find / | grep libidn.so

libidn.so.11 can be seen in the directory: /snap/core18/2538/lib/x86_64-linux-gnu/ Move the file to the directory of other files found by ldd: /lib/x86_64-linux-gnu/

命令：sudo cp /snap/core18/2538/lib/x86_64-linux-gnu/libidn.so.11 /lib/x86_64-linux-gnu

Python ​

1)After the environment dependency query is complete according to the above instructions, call installiFinDPy.py in the interface directory to install

For example: the interface compression package is decompressed and placed in the/lib directory 32-bit call installiFinDPy.py installation in the bin directory of the interface, input parameters are the file path after file decompression For example: zip decompression package is placed in/lib directory

Sudo  python  /lib/bin/installiFinDPy.py  /lib

64-bit call interface installiFinDPy.py installation in bin64 directory, input parameter is the file path after file decompression For example: zip decompression package is placed in/lib directory

Sudo  python  /lib/bin64/installiFinDPy.py  /lib

2)Test the use of interfaces after the environment is deployed

Java ​

1)According to the above instructions, after the environment dependency query is complete, before compiling and using, please add the current directory to the system environment variable LD_LIBRARY_PATH (because this program uses configuration files, do not copy to the system directory, otherwise it will lead to data exception), such as bin64 after decompression is located in the directory/root/Linux

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/root/Linux/bin64

2)Modify Sample Code Login Function, Extract Data Command Function Test

3)Introduce jar package and test with sample code For example, the java directory after decompression is/root/Linux The commands are as follows (note the spaces between commands):

javac -cp /root/Linux/java/Ths/output/ThsJDI.jar test.java
java -cp /root/Linux/java/Ths/output/ThsJDI.jar: test

C++ ​

1)Follow the above instructions and download the official website example to modify the test after the environment dependency query is complete. 2)Unzip linux installation packages and C++ examples

3)Modify example, fill in account number, password

4)Add an interface directory to the system environment variable (bin64 directory for example)

5)Compile and test interface examples

HTTP Interface Instructions ​

HTTP Interface Description ​

Refresh Token and Access Token Description ​

Interface authentication schemes are divided into long-term refresh_token and short-term access_token

refresh_token: Used to obtain the latest valid access_token value;

access_token: Used to obtain specific function data.

1. Refresh Token

The refresh_token validity period is the same as the validity period of the account when it was acquired (subsequent account renewal, permission change must be re-acquired to update the refresh token validity period). refresh_token is used only to request the currently valid access_token or to obtain a new access_token. Refresh_token can only be obtained via the super command client "Tools-refresh_token query".

After refresh token is updated, refresh_token and access_token of all environment will be invalid.

2. Access Token

The access_token can be obtained by using the interface function refresh token, and expires seven days after the initial generation. For example, retrieving the access_token three days before the expiration will refresh the expiration time. Access_token is used to request data directly from the flush server. Single access_token supports up to 20 IPs. If the error 'Device exceeded limit' is reported, the access token can be updated to reset the binding.

Tools such as Postman Use HTTP Interfaces ​

Get Access Token ​

Supercommand select HTTP interface command to generate get_access_token function

After obtaining the refresh token, use the interface to obtain the latest access token.

Retrieve Data ​

Supercommand view fetch function command

Fill in parameters to get data

Language Environments such as Python Use HTTP Interfaces ​

You can refer to the official website example test-HTTP interface application case (python environment)

Get Access Token ​

Retrieve Data ​

Interface Whitelist and Proxy Settings ​

Open Interface Domain Name or IP Whitelist ​

Some users cannot directly connect to the public network due to the company's network security restrictions. They need to add the interface domain name or IP to the whitelist before using the interface network. Otherwise, the login interface will report an error-340 Network unavailable:

Open the interface domain name or IP whitelist as follows:

Note: It is recommended to open a domain name. Because the IP address corresponding to the domain name is not fixed, it must be cache IP first. If the user can only set IP, after opening the interface IP whitelist, you need to set it in the local device hosts.

Interface Settings Agent ​

Windows Environment Settings ​

1)After extracting Windows installation package, open interface super command client:

2)Click the Settings icon on the login interface:

3)Select agent type and fill in agent information:

Note: Select 'HTTP proxy' for your own proxy server, proxy server address and port are required, account number and password can be left blank if not set; special line proxy users contact customer manager for consultation.

Linux Environment Settings ​

Linux environment proxy settings need to be manually modified configuration file system_setting.ini

system_setting.ini Path: 64-bit directory: bin64\Tool\etc\system_setting.ini 32-bit directory: bin\Tool\etc\system_setting.ini

Add as follows：
[System]
proxy=1           //Control whether proxies are used. 1 means using a proxy; 0 means not using a proxy
ip=10.0.16.237    //Proxy server ip
port=802          //Proxy Service Port
type=http         //Proxy type, currently only supports http
user=User         //Proxy Service Identity Verification Account
password=123456   //Proxy service identity verification password
