Python Post 请求 - 通过 Outlook 发送文件时出现 415 错误 API

Question

我在通过 python 的 rest 模块发送文件时遇到了一些问题。我可以发送没有附件的电子邮件，但只要我尝试添加文件参数，调用就会失败，我会收到 415 错误。

我浏览了该站点，发现可能是因为在构建该数据数组时我没有发送文件的内容类型，因此更改它以使用 mimetypes 查询内容类型；还是415.

此线程：python requests file upload 进行了更多编辑，但仍为 415。

错误消息说：

"A supported MIME type could not be found that matches the content type of the response. None of the supported type(s)"

然后列出一堆 json 类型，例如："'application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false"

然后说：

"matches the content type 'multipart/form-data; boundary=0e5485079df745cf0d07777a88aeb8fd'"

这当然让我觉得我仍然没有在某处正确处理内容类型。

谁能看出我的代码哪里出错了？

谢谢！

函数如下：


def send_email(access_token):

    import requests
    import json
    import pandas as pd
    import mimetypes

    url = "https://outlook.office.com/api/v2.0/me/sendmail"

    headers = {
        'Authorization': 'Bearer '+access_token,
    }

    data = {}
    data['Message'] = {
        'Subject': "Test",
        'Body': {
            'ContentType': 'Text',
            'Content': 'This is a test'
        },
        'ToRecipients': [
            {
                'EmailAddress':{
                'Address': 'MY TEST EMAIL ADDRESS'
                }
            }
        ]
    }
    data['SaveToSentItems'] = "true"

    json_data = json.dumps(data)
    #need to convert the above json_data to dict, otherwise it won't work
    json_data = json.loads(json_data)

    ###ATTACHMENT WORK
    file_list = ['test_files/test.xlsx', 'test_files/test.docx']

    files = {}
    pos = 1
    for file in file_list:
        x = file.split('/') #seperate file name from file path

        files['file'+str(pos)] = ( #give the file a unique name
        x[1], #actual filename
        open(file,'rb'), #open the file
        mimetypes.MimeTypes().guess_type(file)[0] #add in the contents type
        )

        pos += 1 #increase the naming iteration

    #print(files)

    r = requests.post(url, headers=headers, json=json_data, files=files)

    print("")
    print(r)
    print("")
    print(r.text)

我想通了！查看 outlook API 文档并意识到我应该在消息 Json 中添加附件作为编码列表，而不是在 request.post 函数中。这是我的工作示例：

import requests
import json
import pandas as pd
import mimetypes
import base64

url = "https://outlook.office.com/api/v2.0/me/sendmail"

headers = {
    'Authorization': 'Bearer '+access_token,
}


Attachments = []
file_list = ['test_files/image.png', 'test_files/test.xlsx']

for file in file_list:

    x = file.split('/') #file the file path so we can get it's na,e
    filename = x[1] #get the filename
    content = open(file,'rb') #load the content

    #encode the file into bytes then turn those bytes into a string
    encoded_string = ''
    with open(file, "rb") as image_file:
        encoded_string = base64.b64encode(image_file.read())

    encoded_string = encoded_string.decode("utf-8")

    #append the file to the attachments list
    Attachments.append({
            "@odata.type": "#Microsoft.OutlookServices.FileAttachment",
            "Name": filename,   
            "ContentBytes": encoded_string        
    })


data = {}
data['Message'] = {
    'Subject': "Test",
    'Body': {
        'ContentType': 'Text',
        'Content': 'This is a test'
    },
    'ToRecipients': [
        {
            'EmailAddress':{
            'Address': 'EMAIL_ADDRESS'
            }
        }
    ],
    "Attachments": Attachments
}
data['SaveToSentItems'] = "true"

json_data = json.dumps(data)
json_data = json.loads(json_data)



r = requests.post(url, headers=headers, json=json_data)

print(r)
