Angular6-读取文本/纯文本的响应主体

标签: angular post response angular2-observables

我正在执行注册操作,当用户成功注册后在后端,我返回他的ID,例如“ 105”,并且当注册失败(用户已经存在)时,我返回“ USER_EXISTS”。我检查了邮递员的要求,回复的正文正确。
在两种情况下,我都返回“纯文本”。

但是,我无法找到如何通过返回的Observable对象获取响应的正文。

在register.component.ts中:

userExists = "";
onSubmit() {

    const newUser : RegisterUser = {  email: this.register.email,
                                  password: this.register.password,
                                  firstName: this.register.firstName,
                                  lastName: this.register.lastName,
                                  phoneNumber: this.register.phoneNumber}


    this.registerService.addUser(newUser)
    .subscribe(response => (this.userExists = response)); //The purpose of this line is to get the body of the text/plain response and assign it into the this.userExists string
}

在RegisterService.service.ts

addUser (registerUser) {

    return this.http.post(this.apiRoot + "User/add", registerUser, httpOptions);
}

默认情况下,角度6产生 JSON 响应 如果您想要文本/纯文本,则应将 responseType 设置为“文本”

 addUser (registerUser) {
    return this.http.post(this.apiRoot + "User/add", {responseType: 'text'});
 }

尝试将其附加到 httpOptions

检查text/plain

在RegisterService.service.ts中,添加地图并将响应转换为文本,如下所示:

addUser(registerUser){

return this.http.post(this.apiRoot + "User/add", registerUser, httpOptions).map(res => res.text());

}
