我想在设备农场（上传测试或应用程序）中使用python + boto3创建上传。 “create_upload”方法可以正常工作，因为它返回一个上传的arn和url以上传到它。上传文件到AWS设备农场

当我尝试使用要求上传文件到这个网址我得到一个错误：

<Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message><AWSAccessKeyId>AKIAJV4C3CWPBUMBC3GA</AWSAccessKeyId><StringToSign>AWS4-HMAC-SHA256

我的代码：

response = client.create_upload(
    projectArn=df_project, 
    name="test.zip", 
    type="APPIUM_JAVA_TESTNG_TEST_PACKAGE", 
    contentType='application/octet-stream' 
) 
test_url = response["upload"]["url"] 
files = {'upload_file': open('/tmp/test.zip','rb')} 
r = requests.post(test_url, files=files, data={})

此外，我使用curl尝试，并requests.post传递文件将数据 attribut：

r = requests.put(test_url, data=open("/tmp/test.zip", "rb").read()) 
print(r.text)

和

cmd = "curl --request PUT --upload-file /tmp/test.zip \""+test_url+"\"" 
result = subprocess.call(cmd, shell=True) 
print(result)

我之前在过去的项目中这样做过。下面是我如何做它的代码片段：

创建一个新的上传

#http://boto3.readthedocs.io/en/latest/reference/services/devicefarm.html#DeviceFarm.Client.create_upload 
print('Creating the upload presigned url') 
response = client.create_upload(projectArn=args.projectARN,name=str(args.testPackageZip),type='APPIUM_WEB_JAVA_TESTNG_TEST_PACKAGE') 
#create the s3 bucket to store the upload test suite 
uploadArn = response['upload']['arn'] 
preSignedUrl = response['upload']['url'] 
print('uploadArn: ' + uploadArn + '\n') 
print('pre-signed url: ' + preSignedUrl + '\n') 

#print the status of the upload 
#http://boto3.readthedocs.io/en/latest/reference/services/devicefarm.html#DeviceFarm.Client.get_upload 
status = client.get_upload(arn=uploadArn) 
print("S3 Upload Bucket Status: " + status['upload']['status'] + '\n') 

print("Uploading file...") 
#open the file and make payload 
payload = {'file':open(args.testPackageZip,'rb')} 
#try and perform the upload 
r = requests.put(url = preSignedUrl,files = payload) 
#print the response code back 
print(r)

希望帮助

我为AWS设备农场工作。当某些请求参数与用于签署URL的内容不匹配时，会发生此问题。我看到这个问题的时候，它与内容类型有关。我建议不要将它传递给CreateUpload请求。如果您确实通过了它，那么在进行PUT调用时，您还需要将其作为请求标头。
