1. Import Os,sys

2. Import Os,sys

3. Import Urllib2

4. Http_str = ' http://127.0.0.1:12345/apps/' + serviceline + '/clusters/' + clustername

5. url = http_str + '/machine_info '

6. req = Urllib2. Request (URL) # URL converted to URL to initiate GET request

7. result = Urllib2.urlopen (req) # initiates get HTTP service

8. res = Result.read () #把结果通过. Read () function reads

9. Slave_info = json.loads (res) #把返回结果 (string) is converted to JSON for ease of processing,

10. Print slave_info[' content ' [' slave '] # printing dict information for JSON strings

post request "POST and get to go to request the difference is that some of the parameters are written inside the program, not in the HTTP request"

3. Import Urllib2

5. Http_str = ' http://127.0.0.1:12345/apps/' + serviceline + '/clusters/' + clustername

6. URL1 = http_str + '/ops/rpm_update ' # URL part

7. Params1 = {"app_rpm_id": "1", "rpm_xxx": rpmxxxxx} #参数部分

8. The params = Json.dumps (params1) # HTTP server requires the incoming params to be a JSON object, so you need to convert it here, and if the HTTP server is not required, you can not convert

11. Response = Urllib.urlopen (url1,params) #发送POST request Print Response # because the HTTP server has already specified that the result of the return is a JSON object, so there is no need to convert to JSON;

12. Print Response.read () # reads the result data through read (), and if HTTP is not returning a JSON object, it needs to be converted to a JSON object.
