創建JSON數組後發送錯誤「not a JSONArray」

Question

我正在綁定格式化數據以發佈到web api。它看起來是正確的，但我得到一個錯誤。

Error: "result":"failed","error_message":org.json.JSONException: JSONObject["leads"] is not a JSONArray.}

這裏是樣品到我的數據應該如何格式化：

{"leadtype":"259","leads":[{"first_name":"John", "last_name":"Anderson", "email":"john.anderson@g-pwatersa.com", "company":"GP Waters", "city":"New York", "state":"New York", "address1":"201 1st St. N.", "country":"United States"}]}

而且這裏是我的樣子使用echo看到的結果：

{"leadtype":"Test","leads":{":first_name":"First",":last_name":"Last",":company":"Company",":email":"myemail@gmail.com",":phone":"8886664455",":city":"Houston",":state":"TX",":zip":"77222",":country":"USA",":source":"Demo"}}

這裏是代碼：

$data = array('leadtype'=>$type); 
$data['leads'] = array(':first_name'=>$firstname, 
':last_name'=>$lastname, 
':company'=>$company, 
':email'=>$email, 
':phone'=>$phone, 
':city'=>$city, 
':state'=>$state, 
':zip'=>$zip, 
':country'=>$country, 
':source'=>$source); 
$data_string = json_encode($data); 
echo "<br>".$data_string."<br>"; 

$ch = curl_init('https://myapi.com');                  
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                  
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                  
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                   
'Content-Type: application/json',                     
'Content-Length: ' . strlen($data_string))                  
);                             

$result = curl_exec($ch); 

echo "<br>".$result."<br>" 

我不明白爲什麼它說它不是一個JSONArray當我使用json_encode()。

您的leads成員是而不是數組 - 這是一個散列。該示例顯示了一個引導對象的數組，而不是傳遞給一個對象。

考慮是這樣的：

$lead = array(':first_name'=>$firstname, 
':last_name'=>$lastname, 
':company'=>$company, 
':email'=>$email, 
':phone'=>$phone, 
':city'=>$city, 
':state'=>$state, 
':zip'=>$zip, 
':country'=>$country, 
':source'=>$source); 
$data['leads'] = array($lead);
