Question

我正在使用advanced-http cordova插件。按照their GitHub repo中的所有步骤进行操作。

但是当我尝试运行我的代码时会弹出一个错误：

缺少必需的“onFail”回调函数

以下是我的代码的样子：

 cordova.plugin.http.post('http://127.0.0.1:5000/api/register', {
        username: this.username, 
        password: this.password,
        firstname: this.firstname,
        middlename: this.middlename,
        lastname: this.lastname,
        birthday: this.birthday,
        age: this.age,
        contact: this.contact,
        address: this.address,
        prisoner: this.prisoner
    }, response => {

        try {
            response.data = JSON.parse(response.data);
            // prints test
            console.log(response.data.message);
          } catch(e) {
            console.error('JSON parsing error');
          }
        }, response => {
          // prints 403
          console.log(response.status);

          //prints Permission denied
          console.log(response.error);
        });

我在这里缺少什么？请帮忙。

您的通话中缺少标题参数。根据问题中链接的文档：

获取网址，数据和标题。

 cordova.plugin.http.post('http://127.0.0.1:5000/api/register', {
        username: this.username, 
        password: this.password,
        firstname: this.firstname,
        middlename: this.middlename,
        lastname: this.lastname,
        birthday: this.birthday,
        age: this.age,
        contact: this.contact,
        address: this.address,
        prisoner: this.prisoner
    },
    { //your_headers_here 
     },
     response=> {//success callback
     },
     response=> {//error callback
     });
