rust实现post小程序(完整代码)
<p>主要是白天折磨了半天，无论如何post出去都不能成功，搞得我专门修改了一堆server的代码，以拦截任何访问服务器的数据，结果还是返回502，结果晚上回来一遍过，也真是奇怪的不行。先把一遍过的代码放出来，防止哪天又卡在这儿过不去。</p><div class="jb51code"><pre class="brush:plain;">//main.rs
use reqwest::Error;
//main.rs
async fn post_request() -> Result<(), Error> {
let url = "http://localhost:30241/dfc/get_block_stock";
let json_data = r#"{"block_source": "gnn"}"#;
let client = reqwest::Client::new();
let response = client
.post(url)
.header("Content-Type", "application/json")
.body(json_data.to_owned())
.send()
.await?;
println!("Status Code: {}", response.status());
let response_body = response.text().await?;
println!("Response body: \n{}", response_body);
Ok(())
}
#
async fn main() -> Result<(), Error> {
post_request().await?;
Ok(())
}</pre></div>
<p>Cargo.toml文件如下：</p>
<div class="jb51code"><pre class="brush:plain;">
name = "untitled"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
tokio = { version = "1.15", features = ["full"] }
reqwest = { version = "0.11.22", features = ["json"] }</pre></div>
<p>意思很简单，就是访问路径为/dfc/get_block_stock,json数据为：</p>
<div class="jb51code"><pre class="brush:json;">{"block_source": "gnn"}</pre></div>
<p>后面就是打印结果了。居然直接一遍过了，在公司可是花了好几小时查遍了所有资料，也改遍了服务器的代码。</p>
<p>最后再贴出服务器的python测试代码：my_http_server.py</p>
<div class="jb51code"><pre class="brush:py;">from sanic import Sanic
from sanic import response, request
from sanic_cors import CORS
app = Sanic(name='my-http-server')
CORS(app)
def success_msg(err_code=0):
res = dict()
res["err_code"] = err_code
res["err_msg"] = "success"
return res
@app.middleware("response")
def cors_middle_res(request: request.Request, response: response.HTTPResponse):
"""跨域处理"""
allow_origin = '*'
response.headers.update(
{
'Access-Control-Allow-Methods': 'POST, GET, OPTIONS, PUT, DELETE',
'Access-Control-Allow-Headers': 'Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization',
}
)
@app.route("/dfc/get_block_stock", methods=['POST'])
async def order_buy_sell(request):
print("order_buy_sell: from: {}, path: {}, data: {}".format(request.socket, request.path, request.json))
res = success_msg(0)
result = dict()
res["result"] = result
return response.json(res)</pre></div>
<p>然后是main.py</p>
<div class="jb51code"><pre class="brush:py;">from my_http_server import app
# Press the green button in the gutter to run the script.
if __name__ == '__main__':
try:
port = 30241
print("my-http-server will started, serving at http://localhost:{}".format(port))
app.run(host="0.0.0.0", port=port)
except KeyboardInterrupt:
print("python-sanic-http-server error.")</pre></div>
<p>最后由于服务器运行用到了sanic组件和一个跨域组件，所以最后记得</p>
<div class="jb51code"><pre class="brush:bash;">pip install sanic
pip install sanic_cors</pre></div>
