这段代码使用了Python的requests
库来发送HTTP POST请求,向本地服务器的API发送数据,并处理响应。接下来我会一步步解释这个代码,并用中文回答。
import requests import json url = "http://localhost:11434/api/generate" headers = { "Content-Type": "application/json" } data = { "model": "qwen2:0.5b", "prompt": "Why is the sky black? Answer in Chinese.", "stream": False } response = requests.post(url, headers=headers, data=json.dumps(data)) print(response.text) if response.status_code == 200: response_text = response.text data = json.loads(response_text) actual_response = data["response"] print(actual_response) else: print("error:", response.status_code, response.text)
{ "model": "qwen2:0.5b", "created_at": "2024-08-22T06:20:16.768091631Z", "response": "天空为什么是黑色的?因为光线穿过大气层时,会受到不同的散射现象影响。具体来说,大气分子(如氮气、氧气等)和水蒸气阻止了阳光中的大部分波长光线,导致太阳光中只有红、橙、黄、绿、蓝五颜六色的光线被散射;而蓝色、紫色光线则被吸收并反射回去。结果就是天空呈现出黑色。", "done": true, "done_reason": "stop", "context": [ 151644,872,198,10234,374,279,12884,3691,30,21806,304,8453,13,151645,198,151644,77091,198,101916,100678,20412,104723,9370,11319,99519,109587,109239,105797,99371,13343,3837,36993,100683,101970,99632,99759,102060,99564,1773,100398,99883,3837,105797,102388,9909,29524,109958,99180,5373,115893,49567,7552,33108,52510,101494,99180,107345,34187,104166,101047,101212,99804,45861,109587,3837,100673,101281,99225,15946,101043,99425,5373,107678,5373,99789,5373,99679,5373,100400,75108,100847,99566,38035,9370,109587,99250,99632,99759,24968,68536,105681,5373,111413,109587,46448,99250,104460,62926,111192,104748,1773,59151,99486,101916,107433,104723,1773 ], "total_duration": 3086970885, "load_duration": 48652771, "prompt_eval_count": 18, "prompt_eval_duration": 53432000, "eval_count": 90, "eval_duration": 2943180000 }
import requests import json
代码首先导入了requests
库用于发送HTTP请求,以及json
库用于处理JSON数据。
url = "http://localhost:11434/api/generate" headers = { "Content-Type": "application/json" }
这里定义了请求的目标URL,即本地服务器上运行的API接口http://localhost:11434/api/generate
。同时,定义了请求头,指定Content-Type
为application/json
,表示请求体中传递的数据格式为JSON。
data = { "model": "qwen2:0.5b", "prompt": "Why is the sky black? Answer in Chinese.", "stream": False }
data
字典包含三个键值对:
"model"
: 指定使用的模型,这里是qwen2:0.5b
。"prompt"
: 提供的提示问题,这里是“Why is the sky black? Answer in Chinese.”。"stream"
: 表示是否希望服务器以流式方式返回数据,这里设为False
。response = requests.post(url, headers=headers, data=json.dumps(data)) print(response.text)
使用requests.post()
方法发送POST请求,传递目标URL、请求头和请求体数据。然后打印服务器的响应内容。
if response.status_code == 200: response_text = response.text data = json.loads(response_text) actual_response = data["response"] print(actual_response) else: print("error:", response.status_code, response.text)
首先检查响应的状态码是否为200(表示请求成功)。如果成功,解析响应文本为JSON格式,并提取实际的回答内容。否则,打印错误信息。
如果服务器正常运行并能处理请求,输出可能会是:
{ "response": "因为天空在没有太阳的情况下没有被光线照亮,所以看起来是黑色的。" }
程序会提取并打印 "因为天空在没有太阳的情况下没有被光线照亮,所以看起来是黑色的。"
。
