Google Translate API

Recently in a task, but little information on the Internet, after a few twists and turns, finally got it. The implementation process is very simple, take out share, so that everyone like me for a long time.

Google translation to upgrade to 2.0 after the fee version, so first need to apply to Google a key. The pay standard is 20 dollars per 1 million text characters (feel small).

Google translation of the work process:
1. Google translation of the request URL: https://www.googleapis.com/language/translate/v2? {parameters} three parameters for translation requests:
1 API key: You need to pay Google, will give you a key;
2 target language: That is, you need to translate the goal language;
3 Source text string: Text that needs to be translated (less than 2k).

2. Here are some examples of different parameters that can be passed to the URL according to your own needs:
1 Specify source and target
HTTPS://Www.googleapis.com/language/translate/v2?key = insert-your-key & source = en & target = de &am P Q = Hello% 20world JSON
{
"Data": {
"Translations": [
{
"Translatedtext": "Hallo Welt"
}
]
}
2) Pass in multiple Q to translate multiple pieces of text
HTTPS://Www.googleapis.com/language/translate/v2?key = insert-your-key & source = en & target = de &am P Q = Hello% 20world & q = My% 20name% 20Jeff JSON
{
"Data": {
"Translations": [
{
"Translatedtext": "Hallo Welt"
},
{
"Translatedtext": "Mein Name ist Jeff"
}
]
}
} 3 does not specify source and translates directly into the target language
HTTPS://Www.googleapis.com/language/translate/v2?key = insert-your-key & target = de & q = Hello% 20w Orld JSON
{
"Data": {
"Translations": [
{
"Translatedtext": "Hallo Welt",
"Detectedsourcelanguage": "en"
}
]
}
3.python implementation of Google translation source:
# Coding:utf8


Import Urllib2
Import JSON
Import Os,sys

Reload (SYS)
Sys.setdefaultencoding ("Utf-8")
