Using Python to implement Baidu API calls

1. First to register Baidu API to become a developer,

Here is a link to the developer application:

Http://api.fanyi.baidu.com/api/trans/product/index

For ease of use, Baidu Translation open platform provides detailed access documentation, links are as follows:

Http://api.fanyi.baidu.com/api/trans/product/apidoc

Detailed usage is listed in the translated document, and the following is the original text of the access document:

Example: Translating Apple from English to Chinese:

Request Parameters:

Q=apple

from=en

To=zh

appid=2015063000000001

salt=1435660288

Platform-assigned key: 12345678

Generate sign:

> Stitching Strings 1

Stitching appid=2015063000000001+q=apple+salt=1435660288+ key =12345678

Get string 1 =2015063000000001Apple143566028812345678

> Calculate signature sign (do MD5 encryption on string 1, note that string 1 must be UTF-8 encoded before MD5 is calculated)

SIGN=MD5 (2015063000000001apple143566028812345678)

Sign=f89f9594663708c1605f3d736d01d2d4

The complete request is:

http://api.fanyi.baidu.com/api/trans/vip/translate?q=apple&from=en&to=zh&appid=2015063000000001 &salt=1435660288&sign=f89f9594663708c1605f3d736d01d2d4

Generation of signed Sign

Signature calculation can be achieved by HASHLIB.MD5 () in the Hashlib module provided by Python

Take the string in the access document as an example:

1. Import Hashlib
2. m = ' 2015063000000001apple143566028812345678 '
3. M_MD5 = HASHLIB.MD5 (M)
4. Sign = M_md5.hexdigest ()
5. Print ' m = ', M
6. Print ' sign = ', sign

Once the signature is received, the URL request is generated as requested in the access documentation , and the translation results are returned after submission. The following are the fields provided by the access documentation and the corresponding descriptions:

{"from": "en", "to": "zh", "trans_result": [{"src": "Apple", "DST": "\u82f9\u679c"}]}

Parse return result

The return value after the URL is submitted is in JSON format, which can be parsed using the JSON module:

1. Import JSON
2. result = ' {' from ': ' en ', ' to ': ' zh ', ' trans_result ': [{' src ': ' apple ', ' DST ': ' \u82f9\u679c '}]} '
3. data = Json.loads (Result)
4. Print data['trans_result ' [0][' DST ']

These are all programs called by the API.
