我在Typescript中定义$ http调用时遇到问题。以前我像这样使用.success和.error:
this.$http({
method: "GET",
url: self.ac.dataServer + url
})
.success((data: any, status: number, headers: (headerName: string) => string, config: ng.IRequestConfig): void => {
self.topics = angular.copy(data);
self.topicsBase = angular.copy(data);
this.$state.transitionTo('home.subjects.subject.admin.topics', {
subjectId: this.sus.subject.id
});
})
.error((data, status, headers, config): void => {
self.topics = null;
self.topicsBase = null;
})
.finally((): void => {
});
现在我改用了.then:
this.$http({
method: "GET",
url: self.ac.dataServer + url
})
.then(
(response): any => {
self.topics = angular.copy(response.data);
self.topicsBase = angular.copy(response.data);
this.$state.transitionTo('home.subjects.subject.admin.topics', {
subjectId: this.sus.subject.id
});},
(response): any => {
self.topics = null;
self.topicsBase = null;
}
);
但这给了我以下错误:
严重级代码说明项目文件行 错误TS2322类型' {}'不能指定类型' ITopic []'。 物业长度'在' {}'中缺少。 admin C:\ H \ admin \ admin \ app \ services \ topicservice.ts 214 严重程度代码说明项目文件行错误TS2322类型' {}'是 不能分配给类型 ' ITopic []&#39 ;. admin C:\ H \ admin \ admin \ app \ services \ topicservice.ts 215
错误出现在我为self.topics和self.topicsBase指定angular.copy(数据)的行上
答案 0 :(得分:2)
类型
'(data: IHttpPromiseCallbackArg<{}>, status: any, headers: any, config: any) => any'
的参数不能分配给'(response: IHttpPromiseCallbackArg<{}>) => any'
类型的参数
您传递的参数比$http()
返回的参数多。
$http({
method: "GET",
url: myURL
})
.then((response): any => { },(): any => {});
