我在通过python的rest模块发送文件时遇到了一些麻烦。我可以发送不带附件的电子邮件很好,但是一旦尝试添加文件参数,调用就会失败,并出现415错误。
我浏览了该网站,发现可能是因为在构建数据数组时我没有发送文件的内容类型,因此将其更改为使用mimetypes查询内容类型。还是415。
此线程:python requests file upload进行了多次其他修改,但仍为415。
错误消息显示:
“找不到与响应的内容类型匹配的受支持的MIME类型。没有受支持的类型”
然后列出了一堆json类型,例如:“'application / json; odata.metadata = minimal; odata.streaming = true; IEEE754Compatible = false”
然后说:
“匹配内容类型'multipart / form-data; boundary = 0e5485079df745cf0d07777a88aeb8fd'”
当然,这让我觉得我在某处仍然无法正确处理内容类型。
任何人都可以在代码中看到我要去哪里吗?
谢谢!
功能如下:
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)
答案 0 :(得分:0)
我知道了!看了一下Outlook API文档,意识到我应该在消息Json中而不是request.post函数中以编码列表的形式添加附件。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)
