#### [ CLI ]

**AWS CLI**  
**创建上传**  
以下命令为 Android 应用创建上传：  

```
aws devicefarm create-upload --project-arn "arn:aws:devicefarm:us-west-2:123456789012:project:070fc3ca-7ec1-4741-9c1f-d3e044efc506" --name app.apk --type ANDROID_APP
```
您可以从 create-project 或 list-projects 的输出中获取项目 ARN。  
输出：  

```
{
    "upload": {
        "status": "INITIALIZED",
        "name": "app.apk",
        "created": 1503614408.769,
        "url": "https://prod-us-west-2-uploads.s3-us-west-2.amazonaws.com/arn%3Aaws%3Adevicefarm%3Aus-west-2%3A123456789012%3Aproject%3A070fc3ca-c7e1-4471-91cf-d3e4efc50604/uploads/arn%3Aaws%3Adevicefarm%3Aus-west-2%3A123456789012%3Aupload%3A070fc3ca-7ec1-4741-9c1f-d3e044efc506/dd72723a-ae9e-4087-09e6-f4cea3599514/app.apk?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20170824T224008Z&X-Amz-SignedHeaders=host&X-Amz-Expires=86400&X-Amz-Credential=AKIAEXAMPLEPBUMBC3GA%2F20170824%2Fus-west-2%2Fs3%2Faws4_request&X-Amz-Signature=05050370c38894ef5bd09f5d009f36fc8f96fa4bb04e1bba9aca71b8dbe49a0f",

        "arn": "arn:aws:devicefarm:us-west-2:123456789012:upload:070fc3ca-7ec1-4741-9c1f-d3e044efc506/dd72723a-ae9e-4087-09e6-f4cea3599514"
    }
}
```
使用输出中的已签名 URL 将文件上传到 Device Farm：  

```
curl -T app.apk "https://prod-us-west-2-uploads.s3-us-west-2.amazonaws.com/arn%3Aaws%3Adevicefarm%3Aus-west-2%3A123456789012%3Aproject%3A070fc3ca-c7e1-4471-91cf-d3e4efc50604/uploads/arn%3Aaws%3Adevicefarm%3Aus-west-2%3A123456789012%3Aupload%3A070fc3ca-7ec1-4741-9c1f-d3e044efc506/dd72723a-ae9e-4087-09e6-f4cea3599514/app.apk?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20170824T224008Z&X-Amz-SignedHeaders=host&X-Amz-Expires=86400&X-Amz-Credential=AKIAEXAMPLEPBUMBC3GA%2F20170824%2Fus-west-2%2Fs3%2Faws4_request&X-Amz-Signature=05050370c38894ef5bd09f5d009f36fc8f96fa4bb04e1bba9aca71b8dbe49a0f"
