如何在承诺中返回身体的价值

如何解决如何在承诺中返回身体的价值

我试图将值（它是图像的二进制数据）放入一个像这样的承诺体内。有没有办法将二进制数据转换为base64编码？

"Promise"{
"IncomingMessage"{
    "_readableState":"ReadableState"{...
    },"readable":false,"_events":[...
    ]{...
    },"_eventsCount":4,"_maxListeners":"undefined","socket":"TLSSocket"{...
    },"connection":"TLSSocket"{...
    },"httpVersionMajor":1,"httpVersionMinor":1,"httpVersion":"1.1","complete":true,"headers":{...
    },"rawHeaders":[...
    ],"trailers":{...
    },"rawTrailers":[...
    ],"aborted":false,"upgrade":false,"url":"","method":null,"statusCode":200,"statusMessage":"OK","client":"TLSSocket"{...
    },"_consuming":true,"_dumped":false,"req":"ClientRequest"{...
    },"request":"Request"{...
    },"toJSON":[...
    ],"caseless":"Caseless"{...
    },"body": //binary values here

现在，访问它们的代码是通过console.log(getto)在异步函数中

async function getMedia(imgMsgUrl,auth) {
const getImage = {
    url: imgMsgUrl,oauth: auth,};
var getto = get(getImage);
await getto;
console.log(getto);
};

如何通过修改异步函数中的代码轻松访问主体？以及如何将其转换为base64编码？

解决方法

由于input_folder_path = '/home/inp' correct_files_folder = '/home/correct' error_files_folder = '/home/error' # All the multiple input files name in a list input_file_names = ['a.csv','b.csv','c.csv'] # Looping over all files for f in input_file_names: # Reading each file into a dataframe df = pd.read_csv(os.path.join(input_folder_path,f)) # Checking whether the column has any special characters or not. If it has one special character also then also it gets saved in error folder if df['ACCOUNT_LOGIN_1'].str.isalnum().sum()!=df.shape[0]: df.to_csv(os.path.join(error_files_folder,f),index=False) else: # No special character. Save in correct files folder df.to_csv(os.path.join(correct_files_folder,index=False) 的结果是一个承诺，因此您无法像访问变量一样访问该值。 您只能使用await在异步函数中获得结果（如上述操作），或者在传递给get(getImage)

的回调函数中执行所需的任何操作

Promise.then()

,

我明白了。这是代码。

async function getMedia(imgMsgUrl,auth) {
const getImage = {
    url: imgMsgUrl,oauth: auth,};
var getto = get(getImage).then(function(response) {
    let buffer = Buffer.from(response.body);
    let base64 = buffer.toString('base64');
    console.log(base64);
});
await getto;
};
