Unirest设置超时
时间: 2024-06-15 21:07:21 浏览: 9
在Unirest中,你可以通过设置连接和读取超时来控制请求的超时时间。以下是设置超时的方法:
1. 设置连接超时:
你可以使用`Unirest.setTimeouts()`方法来设置连接超时时间。该方法接受两个参数,分别是连接超时时间(以毫秒为单位)和读取超时时间(以毫秒为单位)。例如,如果你想将连接超时设置为5秒,可以使用以下代码:
```java
Unirest.setTimeouts(5000, 0);
```
2. 设置读取超时:
如果你只想设置读取超时而不设置连接超时,可以使用`Unirest.setReadTimeout()`方法。该方法接受一个参数,即读取超时时间(以毫秒为单位)。例如,如果你想将读取超时设置为10秒,可以使用以下代码:
```java
Unirest.setReadTimeout(10000);
```
请注意,以上方法需要在发送请求之前进行设置,以确保超时时间生效。

这段代码是用于初始化两个MCP3901模数转换器的函数。下面是对代码的解释:
1. `TRISBbits.TRISB11 = 0`:将RB11引脚设置为输出模式,用于控制MCP3901。
2. `RPOR4bits.RP43R = 0x31`:将RP43引脚配置为RB11引脚的复用功能,用于与MCP3901通信。
3. `REFOCONbits.ROSEL = 0`:选择内部参考电压作为参考电压源。
4. `REFOCONbits.RODIV = 5`:设置参考电压的分频系数为32。
5. `REFOCONbits.ROON = 1`:使能参考电压输出。
6. `RST_AD2_CLR`:清除MCP3901的复位引脚,使其处于正常工作状态。
7. `delay()`:延时一段时间。
8. `RST_AD2_SET`:设置MCP3901的复位引脚,保证其正常工作。
9. `CS_AD2_CLR`:清除MCP3901的片选引脚,开始SPI通信。
10. `ADC_spiMOSI(8,(Status_AD<<1))`:向MCP3901发送SPI数据,设置增益为1。
11. `ADC_spiMOSI(8,0x10)`:向MCP3901发送SPI数据,配置寄存器。
12. `CS_AD2_SET`:设置MCP3901的片选引脚,结束SPI通信。
13. 类似地,通过一系列的SPI通信操作,设置了MCP3901的其他配置寄存器,包括增益、采样率等参数。
请注意,这段代码中存在一些宏定义(例如`RST_AD2_CLR`、`CS_AD2_CLR`等),你需要在代码的其他部分找到这些宏定义的具体内容才能完全理解代码的功能。此外,`ADC_spiMOSI`函数可能是用于SPI通信发送数据的自定义函数,你需要在代码中找到它的定义以了解其具体实现。
关于战争与和平的英语演讲
Ladies and gentlemen,
Today, I want to talk about the two most important concepts that have shaped human history - war and peace.
War has been an unfortunate reality in human history. It has caused immense suffering, destruction, and loss of life. From the ancient wars fought with swords and shields to the modern wars fought with tanks and drones, the devastation caused by war is undeniable. The scars of war can last for generations, and the human cost is immeasurable.
However, war is not inevitable. We have the power to create a more peaceful world. Peace is not just the absence of war, but a state of harmony, where people can live together without fear, violence, or conflict. Peace is the foundation of progress, development, and prosperity.
Achieving peace requires a collective effort from all of us. It requires us to work together, to respect each other's differences, and to find common ground. We must promote understanding, dialogue, and diplomacy, and reject the use of force as a means of resolving conflicts.
We must also address the root causes of conflict. Poverty, inequality, and injustice are all factors that contribute to social unrest and conflict. By addressing these issues, we can create a more equal and just society, where people can live in harmony.
In conclusion, war and peace are two sides of the same coin. We must strive for peace and work towards it every day. Let us choose the path of peace, and work together to create a better world for ourselves and future generations. Thank you.
