我的react-native应用程序无法触发http PUT和POST请求，它无法获取，但是对于PUT来说，这不是我使用web2py构建的RESTful API。 API之所以有效，是因为当我使用curl时，所有请求均被正确触发。这是RESTful API
@request.restful()
def api():
response.view = 'generic.'+request.extension
def GET(*args,**vars):
patterns = [
"/trip[trip]", # endpoint to get all client trips
"/trip/{trip.id}", # endpoint to get trip details by id
"/self[self_driver_trip]", # endpoint to get all self trips
"/self/{self_driver_trip.id}", # endpoint to get a particular self trip
"/driver-trip[driver_trip]", # endpoint to get all client trips
"/driver-trip/{driver_trip.id}", # endpoint to get a particular client trip
"/indi-trip[individual_trip]", # endpoint to get all trips
"/indi-trip/{individual_trip.id}", # endpoint to get an individual trip
"/get_companies[company]", # endpoint to get all companies
"/company/{company.id}", # endpoint to get company details
"/driver[driver]", # endpoint to get all drivers
"/driver/{driver.id}", # endpoint to get driver details
"/get_vehicles[vehicle]", # endpoint to get all vehicles
"/vehicle/{vehicle.id}" # endpoint to get vehicle details

现在这是我的本机应用程序的代码段，该程序段必须发出http PUT请求以更新名为trip的表
let response = await fetch(
API_URL+'/trip',
{
method: 'POST',
body: JSON.stringify({
driver_id: this.props.navigation.state.params.driver_id,
start_mileage: parseInt(this.state.start_mileage),
client: this.state.client,
comp_id: this.state.comp_id,
vehicle_id: this.state.vehicle_id,
start_date: new Date().toLocaleString(),
departure: this.state.departure,
trip_type: this.state.trip_type,
departure_geo_lat: this.state.dep_latitude,
departure_geo_long: this.state.dep_longitude
}),
headers: {
'Content-Type': 'application/json'
}
}
)
和PUT请求
let response = await fetch(
API_URL+'/driver/'+this.state.driver_id,
{
method: "PUT",
body: JSON.stringify({
status: "On a Trip",
current_trip_type: "Client",
current_trip: responseJson.id
}),
headers: {
'Content-Type': 'application/json'
}
}
)
注意：这在我使用flask rest api时有效，但是，我想使用web2py构建后端，所以我决定甚至在我的Android应用程序中也要在web2py中创建RESTful API。 为什么不能与web2py一起使用
