将API输出导出到txt文件

Question

我已经用FastAPI创建了一个简单的API，我希望将输出导出到一个文本文件(txt)中。

这是一个简化的代码

import sys
from clases.sequence import Sequence
from clases.read_file import Read_file
from fastapi import FastAPI
 
app = FastAPI()
 
@app.get("/DNA_toolkit")
def sum(input: str):                        # pass the sequence in, this time as a query param
    DNA = Sequence(input)                         # get the result (i.e., 4)
    return {"Length": DNA.length(),         # return the response
            "Reverse": DNA.reverse(),
            "complement":DNA.complement(),
            "Reverse and complement": DNA.reverse_and_complement(),
            "gc_percentage": DNA.gc_percentage()
            } 

这是输出

{"Length":36,"Reverse":"TTTTTTTTTTGGGGGGGAAAAAAAAAAAAAAAATAT","complement":"ATATTTTTTTTTTTTTTTTCCCCCCCAAAAAAAAAA","Reverse and complement":"AAAAAAAAAACCCCCCCTTTTTTTTTTTTTTTTATA","gc_percentage":5.142857142857143}

我想要的文件

Length 36
Reverse TTTTTTTTTTGGGGGGGAAAAAAAAAAAAAAAATAT
complement ATATTTTTTTTTTTTTTTTCCCCCCCAAAAAAAAAA
Reverse and complement AAAAAAAAAACCCCCCCTTTTTTTTTTTTTTTTATA

有一个简单的方法可以做到这一点。这是我第一次使用API，我甚至不知道这有多可能

Answer 1

您可以使用open方法创建一个新文件，并编写输出。正如@Blackgaurd告诉你的，这不是一个代码编写服务。

，而且我写这段代码非常快，所以可能会出现一些语法错误，。

import sys
import datetime
from clases.sequence import Sequence
from clases.read_file import Read_file
from fastapi import FastAPI

app = FastAPI()

@app.get("/DNA_toolkit")
def sum(input: str):                        # pass the sequence in, this time as a query param
    DNA = Sequence(input)                    # get the result (i.e., 4)
    res = {"Length": DNA.length(),         # return the response
        "Reverse": DNA.reverse(),
        "complement":DNA.complement(),
        "Reverse and complement": DNA.reverse_and_complement(),
        "gc_percentage": DNA.gc_percentage()
        }

    #with open('result.txt', 'w+') as resFile:
        #for i in res:
            #resFile.write(i+" "+res[i]+"\n")

        #resFile.close()

        # Undo the above comment if you don't want to save result into 
        #file with unique id, else go with the method I wrote below...
    filename = str(datetime.datetime.now().date()) + '_' + str(datetime.datetime.now().time()).replace(':', '.')
    with open(filename+'.txt', 'w+') as resFile:
        for i in res:
            resFile.write(i+" "+res[i]+"\n")

        resFile.close()

    return {"Length": DNA.length(),         # return the response
        "Reverse": DNA.reverse(),
        "complement":DNA.complement(),
        "Reverse and complement": DNA.reverse_and_complement(),
        "gc_percentage": DNA.gc_percentage()
        }

Answer 2

dict1={"Length":36,"Reverse":"TTTTTTTTTTGGGGGGGAAAAAAAAAAAAAAAATAT","complement":"ATATTTTTTTTTTTTTTTTCCCCCCCAAAAAAAAAA","Reverse and complement":"AAAAAAAAAACCCCCCCTTTTTTTTTTTTTTTTATA","gc_percentage":5.142857142857143}

with open("output.txt","w") as data:
    for k,v in dict1.items():
        append_data=k+" "+str(v)
        data.write(append_data)
        data.write("\n")

输出：

Length 36
Reverse TTTTTTTTTTGGGGGGGAAAAAAAAAAAAAAAATAT
complement ATATTTTTTTTTTTTTTTTCCCCCCCAAAAAAAAAA
Reverse and complement AAAAAAAAAACCCCCCCTTTTTTTTTTTTTTTTATA
gc_percentage 5.142857142857143

我假设您已经以某种方式获得了调用API的数据。

# data = request.get(...).json()

# save to file:
with open("DNA_insights.txt", 'w') as f: 
    for k, v in data.items(): 
        f.write(f"{k}: {v}\n")
