DAPP应用开发指导¶
配置环境¶
配置客户端¶
wget http://download.lambdastorage.com/lambda/0.6.0/lambda-0.6.0-testnet.tar.gz
mkdir -p ~/LambdaIM && cd ~/LambdaIM
tar zxvf lambda-0.6.0-testnet.tar.gz && cd lambda-0.6.0-testnet
./lambdacli config node tcp://bj1.testnet.lambdastorage.com:26657
./lambdacli config chain-id lambda-chain-test6.0
./lambdacli config trust-node true
./lambdacli config node tcp://bj1.testnet.lambdastorage.com:26657
./lambdacli config node tcp://bj2.testnet.lambdastorage.com:26657
./lambdacli config node tcp://bj3.testnet.lambdastorage.com:26657
./lambdacli config node tcp://bj4.testnet.lambdastorage.com:26657
创建用户并保存助记词¶
- 助记词是用来恢复帐户信息的需谨慎保存
./lambdacli keys add user1
Enter a passphrase to encrypt your key to disk:
Repeat the passphrase:
NAME: TYPE: ADDRESS: PUBKEY:
user1 local lambda1jdev3l38xwxxfq5fdpx6cva2agfxrkugrflur6 lambdapub1addwnpepqdjpeayr7xf7cn74n3t7hcnt6567qlwune7g5uf008qsak4yd60qczc9ulg
**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.
#保存助记词

查询lamb余额：
./lambdacli query account lambda1jdev3l38xwxxfq5fdpx6cva2agfxrkugrflur6
Account:
Address: lambda1jdev3l38xwxxfq5fdpx6cva2agfxrkugrflur6
Pubkey:
Coins: 100000000000ulamb
AccountNumber: 486
Sequence: 0
发行资产¶
创建一个pig币用作存储的支付, 资产最小单位也是u，创建资产需要抵押1000000lamb币。
./lambdacli tx asset create 100000000000upig 1000000000000ulamb --asset-name "pig Coin" --mint-type inflated_mint --total-supply 100000000000000 --inflation 1000000 --adjust-rate 0.5 --adjust-period 10000 --max-adjust-count 5 --genesis-height 10000 --from master --broadcast-mode block
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| --asset-name | string | false | Asset Full Name | |
| --mint-type | string | true | Asset mint type, options: not_mint/one_time_mint/inflated_mint | |
| --total-supply | int | false | 0 | Only for inflated_mint type, total supply is upper limit of asset supply |
| --inflation | int | false | 0 | Only for inflated_mint type, the asset's initial inflation per height |
| --adjust-rate | double | false | 0 | Only for inflated_mint type, the adjust rate about inflation |
| --adjust-period | int | false | 0 | Only for inflated_mint type, adjust inflation when period reached |
| --max-adjust-count | int | false | 0 | Only for inflated_mint type, if reached max adjust count, it won't adjust inflation anymore |
| --genesis-height | int | false | 0 | Only for inflated_mint type, produce asset only if reached genesis height |
| --from | string | true | Name or address of private key with which to sign |

存储业务¶
配置lambgw¶
初始化：
wget http://download.lambdastorage.com/lambda-storage/0.3.2/lambda-storage-0.3.2-testnet.tar.gz
mkdir -p ~/LambdaIM && cd ~/LambdaIM
tar zxvf lambda-storage-0.3.2-testnet.tar.gz && cd lambda-storage-0.3.2-testnet
./storagecli init
cat ~/.lambda_storagecli/config/user.toml
[gateway]
# 服务监听的地址
address = "127.0.0.1:9002"
# 用于访问服务的key
access_key = "accesskey"
secret_key = "secretkey"
运行lambgw¶
./storagecli lambgw run --account user1 --daemonize --log.file /tmp/gateway.log
lambgw使用参考：S3Gateway API文档
使用aws cli接入lambda s3¶
安装awscli.
配置用于访问s3网关的key：
$ aws configure
AWS Access Key ID [None]: accesskey
AWS Secret Access Key [None]: secretkey
Default region name [None]:
Default output format [None]:
aws configure set default.s3.multipart_threshold 512MB
创建bucket¶
aws s3 --endpoint=http://localhost:9002/ mb s3://awstest
上传文件¶
aws s3 --endpoint=http://localhost:9002/ cp /path/to/your/file s3://awstest
列出bucket内容¶
aws s3 --endpoint=http://localhost:9002/ ls s3://awstest
下载文件¶
aws s3 --endpoint=http://localhost:9002/ cp s3://awstest/your-file /tmp/new-file
使用python sdk 接入lambda s3¶
安装boto3
pip install boto3
#!/usr/bin/env python
# coding: utf-8
"""
