我正在按照本教程进行操作，因为许多部分没有向初学者解释，因此很难解决这个问题：https://cloud.google.com/developers/articles/how-to-build-mobile-app-with-app-engine-backend-tutorial
我来到了需要将一些数据上传到数据存储区的部分。他们正在使用.csv文件来实现这一目标。
这是我遇到的教程的一部分：
Create Upload Script
This is the script that actually uploads the simulated information into the backend datastore.
For information about the bulkloader.yaml and more, refer to the App Engine documentation in: Uploading and Downloading Data. Also, you can find the bulkloader.yaml file and the test data here MobileAssistant-Data.
Create a new directory and make it your current directory.
In your editor, create a script file and call it upload_data.sh.
Copy and paste the following code into the file.
#!/bin/sh
appcfg.py upload_data
--config_file bulkloader.yaml --url=http://localhost:8888/remote_api --filename $1 --kind=$2 -e
nobody@nowhere.com
The previous script accepts two arguments separated by a blank space:
./upload_data.sh<data.csv> <class entity name>
The first argument is the name of the csv file that contains the data you want to upload, The second is the name of the entity class to handle the data.
Close and save the file. Notice that the script at this time is intended to be used on local server. It must be modified when the backend application is deployed to the cloud. For example, e-mail “nobody@nowhere.com ” will be changed to an actual e-mail address of the App Engine administrator before deployment.
Places Simulated Data
The simulated data is contained in the file places.csv that you downloaded earlier from the MobileAssistant-Data directory in Mobile Shopping Assistant.
The file contains the following comma separated fields:
name: <place’s name>
placeId: <number that identifies the place>
location: <place’s latitude and longitude coordinates (two values separated by a comma) >
key: <unique key associated with the place>
address: <the place’s address >
Modify Web.xml
To upload data to the datastore, reference the “remote API servlet” and associate it with a URL. You’ll define these mappings in the Web.xml file of the MobileAssistant-Appengine application, as shown next. The web server uses this configuration to identify the servlet to handle a given request.
Note. Notice, you might need to restart Eclipse. if you skip th e Web.xml modification you will get Error 404 Not Found.
<servlet>
<display-name>Remote API Servlet</display-name>
<servlet-name>RemoteApiServlet</servlet-name>
<servlet-class>com.google.apphosting.utils.remoteapi.RemoteApiServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RemoteApiServlet</servlet-name>
<url-pattern>/remote_api</url-pattern>
</servlet-mapping>
Upload Places Simulated Data
To upload the test data to the data store, run the script that uploads the data from your script directory.
Before you upload your data, make sure to start MobileAssistant-AppEngine as a Web Application (in Debug mode) in Eclipse.
./upload_data.sh <places.csv> Place
At the password request, just press enter.
我不了解脚本中的那部分内容。我在桌面上创建了一个文件夹age，放在他们的文件bulkloader.yaml和places.csv中。在该文件夹中是上传脚本。
运行./upload_data.sh <places.csv> Place后，在我的终端中收到以下错误：
upload_data.sh: line 2: appcfg.py: command not found
upload_data.sh: line 3: --config_file: command not found
upload_data.sh: line 4: nobody@nowhere.com: command not found
如何将该数据上传到Google App Engine数据存储区？谢谢。
答案 0 :(得分：0)
appcfg.py是否在您的路径中，如果没有，则在脚本中明确设置路径或将appcfg.py路径添加到PATH
