Question

我尝试执行GET请求以返回单个＆＃34;项目＆＃34;，但是当我将参数发送给Rails时，他们会被拒绝，因为它已经显示作为[object Object]，而不是Rails期望的参数。

之前这对我有用，所以我有点失落。我应该能够输入一个代表项目ID的数字，它应该返回该项目。以下是我输入ID的index.html代码：

const onGetProject = function (event) {
  event.preventDefault()
  const data = getFormFields(this)
  api.getProject(data)
    .then(ui.getProjectSuccess)
    .catch(ui.getProjectFailure)
}

事件在提交时触发：

const getProject = (id) => {
  event.preventDefault()
  return $.ajax({
    url: config.apiOrigin + '/projects/' + id,
    method: 'GET',
    headers: {
      Authorization: 'Token token=' + store.user.token
    }
  })
}

和onGetProject抓取数据并将其发送到API调用：

Started GET "/projects/[object%20Object]" for 127.0.0.1 at 2017-06-27 
22:03:35 -0400
Processing by ProjectsController#show as */*
  Parameters: {"id"=>"[object Object]"}

API调用：

API="${API_ORIGIN:-http://localhost:4741}"
URL_PATH="/projects/${ID}"
curl "${API}${URL_PATH}" \
  --include \
  --request GET \
  --header "Content-Type: application/json" \
  --header "Authorization: Token token=$TOKEN" \
  --data '{
    "project": {
      "id": "'"${INTEGER}"'"
    }
  }'

这是终端显示的内容：

#include <iostream>
#include <string>
#include <fstream>
#include <iomanip>

using namespace std;

void getInformationKeyBoard(int, string[], int[]);
bool openFile(ifstream &infile, string fileName);
void display(int size, string array[]);
void read2Array(ifstream &infile, int size, string array[]);
void printReport(string name[], int score[], int NumberOfStudent);
int main()
{
    const int size = 1024;
    string Name[size], scoreFile[size];
    int score[size];
    int NumberOfStudent;
    const int SIZE = 7;

    ifstream inFile;

    char choice;
    cout << "You want to enter your scores by your keyboard (A) or from your input (B): ";
    cin >> choice;
    if (choice == 'a' || choice == 'A') // It will take information from keyboard
    {
        cout << "How many students do you want to enter: ";
        cin >> NumberOfStudent;
        getInformationKeyBoard(NumberOfStudent, Name, score);
        printReport(Name, score, NumberOfStudent);
    }

    else if (choice == 'b' || choice == 'B') // It will take information from file
    {

        string name;
        char again = 'Y';
        bool close = false;

        cout << "Enter name of file: ";
        cin >> name;
        openFile(inFile, name);
        read2Array(inFile, SIZE, scoreFile);
        display(SIZE, scoreFile);




    }
    else // If you choice is not A,a or B,b
        cout << "Your did not follow the right instruction.";


    cout << endl << endl;
    system("pause");
    return 0;

}

// Open file
bool openFile(ifstream &infile, string fileName){
    infile.open(fileName);
    if (infile)
        return true;
    return false;
}

void getInformationKeyBoard(int size, string Names[], int scores[]) // Information from keyboard
{
    for (int i = 0; i < size; i++)
    {
        cout << i + 1 << ". Student First Name and Last Name: ";
        cin.ignore();
        getline(cin, Names[i]);
        do
        {
            cout << i + 1 << ". Enter the score between 1 and 100: ";
            cin >> scores[i];
        } while (scores[i] > 100 || scores[i] < 0);

    }
}



void read2Array(ifstream &infile, int size, string array[]){
    int index = 0;
    string line;

    while (getline(infile, line)){
        array[index] = line;
        ++index;
    }
}

// Display array
void display(int size, string array[]){
    for (int index = 0; index < size; ++index){
        cout << array[index] << endl;
    }
}


void printReport(string name[], int score[], int NumberOfStudent)
{
    int lowest, highest, mean;
    cout << "Enter lowest score: ";
    cin >> lowest;
    cout << "Enter highest score: ";
    cin >> highest;
    cout << "Enter mean score: ";
    cin >> mean;

    cout << "================================================================================";
    cout << setw(10) << "Number of scores = " << NumberOfStudent << endl;
    cout << setw(10) << "Lowest Score = " << lowest << endl;
    cout << setw(10) << "Highest Score = " << highest << endl;
    cout << setw(10) << "Mean Score = " << mean << endl;
    cout << "Name" << setw(15) << "Score" << setw(15) << "IsLowest" << setw(15) << "IsHighest" << setw(15) << "Mean" << endl;
    cout << "-----------------------------------------------------------------" << endl;
    cout << name[NumberOfStudent] << endl;
    cout << endl;

}

我编写了一个脚本，该脚本应该为单个ID执行GET请求，但这会返回所有内容，而不是＆＃34; show＆＃34;我希望Rails能够执行：

脚本：

Number of scores = 3
Lowest Score  = 82
Highest Score = 92
Mean Score = 87
Name    Score    IsLowest    IsHighest    >=Mean
F1 L1    82         Y              N          N
F2 L2    87         N              N          Y
F3 L3    92         N              Y          Y

我在我的后端使用Ruby on Rails，并且我能够成功执行GET请求，该请求返回所有Projects及其嵌套任务的索引，如预期的那样。但是，我无法获得单个GET请求，并且不确定我的代码可能出现了什么问题。

如果您需要任何其他代码或信息，请与我们联系。谢谢你的帮助！

由于ID是一个对象，我需要使用id.project.id更明确地访问该值。

一旦我在我的API调用中替换了它，它就成功执行了，并且返回了我请求的单个Project。这是工作代码：

    const getProject = (id) => {
      event.preventDefault()
      return $.ajax({
        url: config.apiOrigin + '/projects/' + id.project.id,
        method: 'GET',
        headers: {
          Authorization: 'Token token=' + store.user.token
        }
      })
    }

Params在GET请求中作为[object Object]发送，Rails不接受
