Python3 开发以及部署 RESTful API项目（Python3 + Django2.0 + Django REST FrameWork + Centos7 + uWsgi + Nginx） 2 | 文档分为两个部分，分别从开发和部署两个方面先介绍项目流程，然后会说明项目中最常遇到的问题以及解决方案。如果项目中有什么处理不正确的地方，也希望大家给予指正、交流。 3 | 4 | 1. 开发环境采用Python3.6.3版本，项目采用Django2.0，Django REST FrameWork3.7.7去搭建。 5 | 6 | 2. 部署的时候，系统版本为Centos7，uWsgi版本使用本文发布时最新的2.0.15，Nginx版本1.13.7 7 | 8 | ## 第一部分 开发流程以及问题说明 9 | 由于项目本身基于 Token 的身份验证，另外有些接口不只是处理一个表里的数据，直接通过ORM不太好映射，所以并没有完全按照Django REST FrameWork进行开发，并且只采用GET和POST方法。 10 | 11 | ### 一、开发步骤 12 | 首先搭建开发环境并且创建一个新的项目。 13 | #### 1. 安装Python3：如果使用的是 Mac OS X ，系统可能已经预装了 Python 。我们可以通过homebrew安装Python3。 14 | ``` shell 15 | $ brew install python3 16 | ``` 17 | 安装了Python3之后，会有pip3，使用pip install XXX 新安装的库会放在这个目录下面python2.7/site-packages使用pip3 install XXX 新安装的库会放在这个目录下面python3.6/site-packages如果使用python3执行程序，那么就不能import python2.7/site-packages中的库 18 | #### 2. 安装Django和Django REST FrameWork：可以下载django最新版本,若想指定版本,请在命令后面加上版本号。 19 | ``` shell {.line-numbers} 20 | $ pip3 install django 21 | $ pip3 install djangorestframework 22 | ``` 23 | ``` shell {.line-numbers} 24 | $ pip3 install django==版本号 25 | $ pip3 install djangorestframework==版本号 26 | ``` 27 | #### 3. 创建一个新的项目。 28 | ``` shell {.line-numbers} 29 | $ cd ~ 30 | $ django-admin.py startproject attendances 31 | $ cd attendances 32 | $ python manage.py startapp user apps/user 33 | ``` 34 | #### 4. 将新user应用和rest_framework应用添加到配置文件attendances/settings.py文件的INSTALLED_APPS。 35 | ``` python {.line-numbers} 36 | INSTALLED_APPS = ( 37 | ... 38 | 'rest_framework', 39 | 'apps.user', 40 | ) 41 | ``` 42 | #### 5. 写接口代码前的一点准备。 43 | 做完以上步骤，我们就把项目开发需要的环境搭建完成了，接下来就可以在我们的项目中添加接口了。 44 | 45 | 另外还有一点要说明的是，为了给我们的api增加版本控制，我们的文件目录和路由是这样处理的，这样我们就可以通过添加新的版本文件并且修改配置，同时运行多个版本的接口： 46 | 47 | **文件目录结构** 48 | 79 | 80 | **路由** 81 | ``` python {.line-numbers} 82 | # 项目路由 83 | urlpatterns = [ 84 | url('admin/', admin.site.urls), 85 | url(r'^api/v1/', include('apis.api_v1.urls', namespace='api-v1')), 86 | ] 87 | ``` 88 | ``` python {.line-numbers} 89 | # apis下面的路由 90 | from apis.api_v1.user import views as api_user 91 | 92 | urlpatterns = [ 93 | # user 94 | url(r'^user/$', api_user.user, name='user'), 95 | ] 96 | 97 | app_name = 'api-v1' 98 | ``` 99 | **调用地址：** https://{Domain}/api/v1/user 100 | 101 | **请求方法：** GET-获取用户信息 POST-修改用户信息 102 | 103 | > 文件说明：apis存放的是api接口文件，app存放的是应用或者可以说是模块，attendances是项目文件存放一些项目配置，static静态文件，attendances.xml是uWsgi的配置文件，requirements.txt是一些项目相关的依赖，test.py是为了测试uWsgi是否配置成功的文件。 104 | #### 6. 创建一个可以使用的模型以及Serializer类、Django视图。 105 | **在apps/user/models.py创建User模型** 106 | ``` python {.line-numbers} 107 | """ 108 | 用户模块 109 | """ 110 | from django.db import models, transaction 111 | 112 | class User(models.Model): 113 | """ 114 | 用户信息表 115 | """ 116 | user_id = models.AutoField(primary_key=True, verbose_name='用户id') 117 | user_guid = models.CharField(max_length=150, verbose_name='用户guid') 118 | user_name = models.CharField( 119 | max_length=100, blank=True, null=True, verbose_name='用户名') 120 | real_name = models.CharField( 121 | max_length=50, blank=True, null=True, verbose_name='真实姓名') 122 | avatar = models.CharField( 123 | max_length=250, blank=True, null=True, verbose_name='头像') 124 | mobile = models.CharField( 125 | max_length=50, blank=True, null=True, verbose_name='手机') 126 | balance = models.DecimalField( 127 | max_digits=8, decimal_places=2, blank=True, null=True, verbose_name='账户余额') 128 | available_balance = models.DecimalField( 129 | max_digits=8, decimal_places=2, blank=True, null=True, verbose_name='可用金额') 130 | frozen_balance = models.DecimalField( 131 | max_digits=8, decimal_places=2, blank=True, null=True, verbose_name='冻结金额') 132 | all_balance = models.DecimalField( 133 | max_digits=8, decimal_places=2, blank=True, null=True, verbose_name='累计金额') 134 | wx_open_id = models.CharField(max_length=150, verbose_name='微信OpenID') 135 | wx_union_id = models.CharField( 136 | max_length=150, blank=True, null=True, verbose_name='微信UnionID') 137 | create_date = models.FloatField(blank=True, null=True, verbose_name='创建时间') 138 | last_login_date = models.FloatField( 139 | blank=True, null=True, verbose_name='最后登录时间') 140 | ip_address = models.CharField( 141 | max_length=50, blank=True, null=True, verbose_name='IP地址') 142 | gender = models.IntegerField(blank=True, null=True, verbose_name='性别') 143 | province = models.CharField( 144 | max_length=50, blank=True, null=True, verbose_name='省份') 145 | city = models.CharField( 146 | max_length=50, blank=True, null=True, verbose_name='城市') 147 | session_key = models.CharField( 148 | max_length=150, blank=True, null=True, verbose_name='会话秘钥') 149 | is_notify = models.IntegerField(blank=True, null=True, verbose_name='是否开启打卡通知') 150 | 151 | @classmethod 152 | def update_user_balance(cls, user_id, amount): 153 | #

test.py 321 | def application(env, start_response): 322 | start_response('200 OK', [('Content-Type','text/html')]) 323 | return [b"Hello World"] # python3 324 | ``` 325 | 运行uwsgi,http :8000表示使用http协议，端口号为8000，wigi-file则表示要运行的wsgi应用程序文件。 326 | ``` shell {.line-numbers} 327 | # test.py 328 | $ uwsgi --http :8000 --wsgi-file test.py 329 | ``` 330 | uwsgi运行后打开浏览器，访问http://127.0.0.1:8000/ ，或者是相应服务器地址的8000端口，就可以看到hello world 页面了。 331 | #### 3. 安装Django以及项目依赖，通过uWsgi测试项目是否能正常运行 332 | 安装依赖 333 | ``` shell {.line-numbers} 334 | $ pip3 install django 335 | $ pip3 install djangorestframework 336 | $ pip3 install pycrypto 337 | ``` 338 | Django通过uWsgi测试，如果能正常浏览则运行成功，静态文件无法访问的话，我们这里先忽略，后面会通过Nginx配置静态资源访问 339 | #### 4. 安装MySQL,也可以直接使用SQLite或PostgreSQL、Oracle数据库，Django支持多种数据库，根据配置安装不同的驱动，本项目采用MySQL，数据表结构以及链接配置请参考文档 340 | ``` shell {.line-numbers} 341 | $ pip3 install mysql 342 | $ pip3 install mysql-server 343 | $ pip3 install mysql-devel 344 | ``` 345 | MySQL的安装可以参考文档：[MySQL 安装 | 菜鸟教程](http://www.runoob.com/mysql/mysql-install.html) 346 | #### 5. 连接uwsgi与Django 347 | 该步骤只是检测Django项目能否在uwsgi下运行，下面我们将配置xml的启动配置文件 348 | ``` shell {.line-numbers} 349 | $ uwsgi3 --http :8000 --module attendances.wsgi 350 | ``` 351 | xml的启动配置文件 352 | ``` python {.line-numbers} 353 | 354 | 127.0.0.1:8000 355 | /root/web/attendances/attendances 356 | attendances.wsgi 357 | 4 358 | uwsgi.log 359 | 360 | ``` 361 | 进入项目执行以下命令 362 | ``` shell {.line-numbers} 363 | $ uwsgi3 -x attendances.xml 364 | ``` 365 | #### 6. 安装nginx 366 | ``` shell {.line-numbers} 367 | $ wget http://nginx.org/download/nginx-1.13.7.tar.gz 368 | $ tar -zxvf nginx-1.13.7.tar.gz 369 | $ ./configure 370 | $ make 371 | $ make install 372 | $ nginx 373 | ``` 374 | 通过链接查看nginx是否启动成功:http://192.168.2.110 375 | #### 6. 通过配置nginx.conf文件连接Django、uWsgi与Nginx 376 | 在/etc/nginx/nginx.conf修改nginx.conf 377 | ``` shell {.line-numbers} 378 | server { 379 | listen 80 default_server;#暴露给外部访问的端口 380 | listen [::]:80 default_server; 381 | server_name 127.0.0.1; 382 | index index.py index.html; 383 | root /root/web/attendances/attendances; 384 | 385 | location / { 386 | include uwsgi_params; 387 | uwsgi_pass 127.0.0.1:8000;#外部访问80就转发到内部8000 388 | } 389 | 390 | location /static/ { 391 | alias /root/web/attendances/attendances/static/;#项目静态路径设置 392 | } 393 | } 394 | ``` 395 | 保存nginx.conf执行nginx -t命令先检查配置文件是否有错，没有错就执行以下命令：nginx启动nginx，可以通过链接查看nginx是否启动成功,之前启动过的话重启nginx. 396 | 重启nginx 397 | ``` shell {.line-numbers} 398 | $ nginx -t 399 | $ nginx -s reload 400 | ``` 401 | 以上步骤都没有出错的话，打开你的浏览器，输入以下链接，记得关闭系统防火墙或者开放8000端口 402 | http://192.168.2.110/api/v1/user/?token=21cd4161-2a78-451e-8979-5fbd8538935e&user_id=4 （请将该ip替换成你的服务器ip） 403 | 网站访问成功！ 404 | ### 二、相关问题说明 405 | #### 1. Nginx和Django静态文件处理 406 | Django项目可以正常打开，但是静态文件引用路径还有问题，在Django开发时Django自己可以正确处理静态文件的路径，但是部署后Nginx去无法找到静态文件路径。 407 | 408 | 检查Nginx配置文件夹sites-enabled里的nginx-pro文件，确保里面默认的try_files要删掉或者注释掉，否则Nginx会因此检查静态文件是否存在。 409 | 410 | 将Django的静态文件集中起来，Django为此有专门的工具 411 | 412 | 现在Django的Settings文件中加上StATIC_ROOT，把静态文件都集中到这个路径下 413 | 414 | ``` shell 415 | STATIC_ROOT = os.path.join(BASE_DIR, "static/") 416 | ``` 417 | 执行命令 418 | 419 | ``` shell {.line-numbers} 420 | $ python3 ./manage.py collectstatic 421 | ``` 422 | 这样所有Django前后台的静态文件都会集中到项目文件夹pro下static中，另外nginx-pro其中一个配置location /static即可让Nginx来处理静态内容。 423 | #### 2. Nginx权限问题(Nginx 403 forbidden) 424 | 如果nginx用户没有web目录的权限，则会导致该错误。解决办法：修改web目录的读写权限。或者是把nginx的启动用户改成目录的所属用户，重起一下就能解决，在nginx.conf头部加入一行：user root;因为项目是在root用户下建立的，通过这个用户去访问资源就可以访问。 425 | ``` shell 426 | chmod -R 766 /web 427 | ``` 428 | #### 3. Nginx转发出现错误(502 BAD GATEWAY) 429 | 430 | ``` shell 431 | $ setsebool -P httpd_can_network_connect 1 432 | ``` 433 | > 如果访问不了可以查看Nginx下的error.log文件，查看具体的问题，再找解决方法。 434 | ## 分享一些中文文档资料 435 | > 有关Python、Django以及Django REST FrameWork的学习可以参考官方文档，以及以下中文文档，在网上找了很久，感觉以下这几个中文文档还是写的很不错的。 436 | 437 | [**Python：** 廖雪峰老师Python教程，基于最新的Python
